Study of foraging behaviour in the communities of Kanha Tiger Reserve with respect to different aspects of memorization

Foraging.jpg

“Memory” and how it is formed is indeed one of the widely explored processes by lots of neuroscientists and psychologists and still it remains a mysterious topic after so many years of consistent research. In recent years we have reached a rather general consensus about the stages of processing that are involved in human memory. This consensus is reflected in the development of a new class of psychological theories that differs radically from the more traditional approach to the same problems. This new approach is “Human Information Processing” which is a direct result of an attempt to view and understand “memory” as a complex system, with many interacting stages, rather than as something that mediates between the presentation of a stimulus to the subject and his eventual response.

In all the memory system aspects, “working memory” plays an essential role in complex cognition. Everyday cognitive tasks such as calculating monthly budget, reading newspaper and so on involves multiple steps with intermediate results that need to be kept in mind temporarily to accomplish the task at hand. “Working memory” is a theoretical construct that has come to be used in cognitive psychology to refer to the system underlying the maintenance of task-relevant-information during the performance of a cognitive task. (Baddeley &Hitch, 1974; Daneman and Carpenter, 1980)

As reflected by the fact that it has been labelled “the hub of cognition” and proclaimed as “perhaps the most significant achievement of human mental evolution, “it is a central construct in cognitive psychology.

This article however focuses on the working and long term memory and its process in depth and highlights key insights about the foraging behaviours of the Gondi and Baiga (tribal communities) communities that are settled in and around the Kanha Tiger Reserve.  The idea is to understand their foraging behaviour with respect to the mental maps that exists within their memory. Along with foraging as an activity, there are many other examples from their everyday lives like during agriculture practices, cleaning the house, cooking, constructing new house, cultural celebrations and so on where one can understand their concept of memory and how it is passed on from one generation to other.

  • Memory and its basic principles

Memory by and large possesses few fundamental principles. These set of principles might not apply to all types of memory but still intend to use. The reason being there are many areas of memory research where there is simply not enough data to assess, yet. The 7 basic principles of memory are as follows:

1.1.a. The cue-driven principle: In all situations, the act of remembering begins with a cue that initiates the retrieval process.

1.1.b. The encoding-retrieval principle-Memory depends on the relation between the conditions at encoding and the conditions at retrieval .Accepting this principles entails accepting 4 consequences-

  1. Items do not have intrinsic mnemonic properties
  2. Processes do not have intrinsic mnemonic properties
  • Cues do not have intrinsic mnemonic properties
  1. Forgetting is due to extrinsic factors

 

1.1.c. The cues overload principle: Cues can become associated with more and more items at various encoding opportunities, thus reducing their effectiveness at the time of retrieval.

1.1.d. The reconstruction principle: Memory, similar to other cognitive processes, is inherently constructive. Information present at encoding, cues at retrieval, memories of previous recollections, indeed, any possibly useful information, are all exploited to construct a response to a cue.

1.1.e. The impurity principle: One consequence of the reconstruction principle is the realization that on any task, people recruit and use a wide variety of information and processes. Therefore, tasks are not pure and processes are not pure, and inferences based on the assumption that a task taps a particular memory system or requires only one particular process are likely to be misguided.

1.1.f. The relative distinctiveness principle- Items will be well remembered to the extent that they are more distinct than competing items at the time of retrieval.

1.1.g.The specificity principle- Those tasks that require specific information about the context in which memories were formed are more vulnerable to interference or forgetfulness than those that rely on more general information.

 

So, from the above principles it is clear that brain helps in activating some cues and one needs to explore where these cues are actually formed, how information gets converted from a mere raw form to a memory form and how it is retrieved when needed. It has been found that more specific the cue that working memory attaches to a new learning, the easier it is for long term memory to identify the item being sought.  This process leads to an interesting phenomenon regarding the long term memory storage and retrieval.

“We store by similarity but we retrieve by difference.” Long term memory most often stores new learning’s into a network that contains learning’s with similar characteristics or associations, as perceived by the learner. This network identification is one of the connections made in working memory during rehearsal and closure. To retrieve an item, long term memory identifies how it is different from all the other items in that network.

Sharing one example from the village, where I did my research work:

I asked the Ahilyaji (the lady of the house) How you will identify your best friend in the village crowd? Now, she instantly told me “I can.” Now, if I try to go back to my question and look at the entire process, it followed few steps. She didn’t come to her answer without following these steps. How would she recognize her best friend in the village? It’s not because she has two legs, two hands and one nose. These characteristics are similar to all. So, rather than similarities one needs to see some differences, that are subtle in nature. In this case, it may be her walking style, voice or hairstyle that distinguishes her from the crowd. These unique characteristics are called “Critical attributes” that helps a person to retrieve the information faster and in an efficient manner.

  • Process of “Human Information Processing”

Firstly, newly presented information would appear to be transformed by the sensory system into its physiological representation (which may already involve a substantial amount of processing on the initial sensory image) and this representation is stored briefly in a sensory information storage system. Following this sensory storage, the presented material is identified and encoded into a new format and retained temporarily in a different storage, usually the short term memory. Then if extra attention is paid to the material, or if it is rehearsed frequently enough, or if it gets properly organized, the information is transferred to a more permanent memory system. The capacity of this more permanent memory system is so large that information that is stored must be organized in an efficient manner, if it is ever to be retrieved.

Finally, when it is necessary to retrieve information from memory, decision rules must be used, both to decide how exactly to get access to the desired information and then decide what response should be made to the information that has been retrieved. To understand this more, one needs to understand the internal structure of brain where all the sensory information is saved and then processed with the help of electric signals. The internal structure of brain broadly consists of brain stem, limbic system and the cerebrum. The brain stem looks at the vital functions like respiration, digestion and heartbeat. The limbic system comprises of thalamus, hypothalamus, hippocampus and amygdala. All the incoming sensory information is stored in the thalamus at an initial level. Hypothalamus regulates the normal state of the body and it is the hippocampus that is responsible for consolidating learning and converting information from working memory to the long term storage via electrical signals. Also this part goes through neurogenesis. Amygdala regulates individual’s interactions with external stimuli or environment. E.g. Fear, escape and mate and so on. This experience also shifts into the long term memory due to presence of extreme emotions within them.

 

“Association of emotions” with any experience makes the incidents or events more concrete and hence the chances of its retrieval are higher. The brain’s amygdala encodes emotional messages when they are strong and bonds them to learning/concrete events for long term storage. Emotions have a higher priority than cognitive processing for commanding our attention.

 

The classical example of this that I found in the village of Kadala was the entire process of “Constructing a house” by a small Baiga family of 6 people. House is a small institution itself when the family shares their togetherness, care and boding and so there is a small emotional element when it comes to sharing the memory of the same. They shared the entire process of how they make the furnace, make “Kavli (Tiles that are used above the roof) for their house, how much time does it take, what are the challenges in making it, what precautions do they have to take care of, how do they measure area, what measuring tools do they use and how do they keep an account of time. So, they are able to share all this in a detailed manner, because all this is a part of their long term memory and the events are placed in a concrete manner.

Secondly, the community member’s approximation is also quite an accurate one, because their approximation has some basic ground rules that are scientific, which their older generation was quite aware of.

Eg-1: The making of the furnace is a round shaped structure and not any other geometrical shape because they know that heat will be equally distributed to all parts (Central to periphery) So they do use principles that are efficient but might not be able to share the reasons for each.

 

Eg-2: The Gonds of this village told me about a ritual they carry out post a man is dead. On the 13th day after a person’s death, they bring an alive fish to their house and do some “puja” and then leave the fish back to the pond from where they brought it. I asked many people why they bring only fish. Do they get fish every time of the year? What if the fish is not available? Is it fine to carry any other living form other than a fish like a turtle or a tortoise and so on? What is the relevance of this ritual? Many people responded to these questions in different ways. Few said fish is essential and others said if not fish it’s fine to get some other life form too. But when I investigated this more through few more people who are called the “Wise and intellectual group of men” they shared that fish cannot be substituted by any other life form. So, the reason for having a fish in the ritual is something like this:

In a women’s womb, who has conceived a month or 2 ago, the zygote in its growing stage looks like a “Fish shaped structure” So in the Gond culture, they respect “Shapes and forms” more than anything. So, the analogy is by bringing the fish back, the people are actually welcoming the new form of birth of a person. They are praying the Almighty to bring this dead person back in the same life form that is-Human form, by honouring the shape of the fish. This looks quite interesting and insightful and opens the doors for further investigation.

Listening to this, it may be a possibility that someone in the past exposed them with the knowledge of embryology, otherwise how would they know such intricate shape of the zygote and its resemblance with the fish. Or maybe they or they forefathers had done dissections and so on. So the possibilities can be many, but this ritual is such an important and intricate part of their culture due to the emotional connection and the loss of life scenario. The brain’s amygdala encodes these information capsules and keeps it safe for further retrieval.

 

  • Memory System- A system for Perception and Memory

The basic components that form the memory system are sensation, perception, short term memory (working memory) and long term memory and last but not the least is the retrieval from the memory. The system is divided into 2 main sections- Perception and memory. By perception, we include those processes involved in the initial transduction of the physical signal into some sensory image and the identification of that list of features with a previously learned structure.  By memory we mean the processes that act to retain the material that was sent to it from the perceptual system.

We also need to understand that brain systems are specialised for different functions. To characterize these specializations we focus on basic trade-offs that exists within this conceptual framework. The PMC (Posterior perceptual and motor cortex), PFC (Pre frontal cortex) and HCMP (Hippocampus and related structures) play an important role in it.

4.1 Memory and its theories & its interpretation with respect to the foraging behaviour

So, now after understanding the brain structure, how we retrieve memory and so on, it’s important to understand what the theorists believe in memory and how do they perceive it. There are three prominent theories of memory that are fundamentally debated, discussed and critiqued:

  • Decay: This approach primarily revolved around the issue of the permanence or non-permanence of memory. Decay theory proposes that we learn something; a memory (trace) is formed. This trace will gradually fade away if the imprint is not occasionally reactivated. The way one remembers is by rehearsing and keeping these traces active. This is much like the physiological theory of reverberation of neurons and continues to discharge for some time and eventually stop. Hebb’s theory stated that when a pattern of neuron fire, it could be equated with a “pattern” of memory. If it keeps firing, the same memory remains and if it stops, we forget.
  • Interference – This approach maintains that a memory trace is a “permanent entity.” If we forget, it is because other permanent memories are stronger and are blocking retrieval. This is analogous to a physiological theory of structural change of neurons this says that neurons, once fired, undergo a permanent change. This pattern of permanent change is equated with a memory trace. Once it is present, it is permanent but other traces could be superimposed at a later time and therefore, retrieval could be blocked.
  • Gestalt– This theory or approach believes that traces are neither all permanent nor all temporary. Traces are constantly being transformed and memory is a fluid process. This is psychologically hard to conceive because it presupposes that somehow neurons have control over their own destiny and can interact and form new connections on their own.

Visual memories, such as remembering where to turn to drive home, seem effortless unless retrieval is compromised by dementing illnesses or injuries affecting the brain’s frontal lobes (at the front of the brain).  Studies have shown that both the frontal lobe and the occipital lobe (at the back of the brain) are critical in retrieving visual memories. But just how and when the brain’s frontal lobe affects this visual sensory region at the back of the brain during memory processes remains a mystery. The researchers have found, however, that when people remember an object’s previous spatial location, the brain is activated as if the person were actually seeing that object in its previous location.

This finding supports the notion that memory is a constructive process where various brain regions reactivate details from a previous experience and the combined information creates a memory. That is, unless this process is disrupted.

 

So, the villagers who go for foraging for hours together don’t necessarily walk together all day long. They distribute themselves into different areas and come back to the common location, they all have decided. The mental map of the territory helps them to navigate in a better way. The spatial orientation which is primarily the responsibility of the parietal lobe and the movement function which is regulated by the cerebellum enhances their activity during this period. These mental rehearsals of the motor skills, ultimately improves their performance and makes them more skilled and efficient in the foraging activities.

My experience with the foraging groups that I had accompanied was something like this:

 

4.1. a. There are different groups based on gender and age differentiation in a village. Men and women groups used go separately with their own groups. Children mostly used to accompany their mothers. If the child is an adolescent and a male, he might go with his father and in rest of all cases, children, accompanied their mothers.

4.1. b Timings – Kadala village is bang next to the forest and so these people usually go early morning or late afternoons.

4.1.c. The time spent by these communities in the forest varies from season to season and from tribe to tribe Gonds usually go for shorter durations like 2-3 hours in summers and for longer durations during rainy and winter season. The reason is that they collect some fruits and vegetables during the rainy season from the forest and it’s a leisure and relaxation time for them to enjoy the beauty of the forest. One of the man, named Bhola Singh Meravi said- “It’s like a picnic for us.” Baiga’s on the other hand collect leaves- Leaves of Mahul creeper, which they later sell and earn their money. It’s a livelihood option for them. So baiga’s go early morning to the forest and come in the afternoons.  Unlike Gonds, they do cover larger landscapes.

4.1.d. The foraging groups of villagers vary from 5-7 and even 2-3. During foraging when they enter the forest, they maintain one hand distance while walking in a straight line, like a single file in an army. One behind the other helps them to follow and also keep a steady pace. They are alert if they hear any animal’s noise or any unfamiliar sound.

4.1.e. The routes are imprinted in their brain and so they are able to navigate and forage successfully. Following are things they usually collect from the forest, during their one visit:

  • Timber collection / Firewood (around 8-10 logs per person)
  • Mahul creeper (they make ropes out of it)
  • Mahul leaves that are used as serving plates
  • Tendu, Sarai, Rehartiya, Jamun and Baramsiya sticks that are used as toothbrush for the family.
  • Fruits during the season- Mango, Plums, Tendu, Chaar, Dumar and Sihar (Sihar is a fruit of Mahul tree)
  • Vegetables during the season- Pihari (a type of mushroom that is red and white in colour) Pudpura (it’s a black coloured round vegetable) Pudpura is their favourite vegetable and they say, it tastes delicious. One of them compared it with mutton and said it tastes better than our favourite dish, mutton.
  • Bhodo, Saraipihri and Baanspihari( all different species of mushroom)
  • In rainy season, they do collect grass for their cattle.
  • Chindi tree- For making brooms in their houses.

4.1.f. They don’t carry any tools like knife or axe with them. The villagers said that since now the laws are strict, it is difficult to carry these things. If you don’t have any weapon, forest people will not punish you and let you go.

4.1. g. The children who accompany their mother usually are a kind of support system for them. It’s an unsaid way of their culture. If there is a woman with her son or daughter, they will assist their mothers and ensure everything is collected. They will keep an eye if there is an animal in the surrounding. They will collect small things like fruits, toothbrush sticks and so on.

4.1. h. These foraging groups are by and large people from the same kinship. They usually go for foraging 2-3 days in a week.  Gonds usually go in 2-3 days where Baiga usually go every day because their livelihood needs forces to collect leaves (Mahul) every day. They usually take their lunch also.

4.1.i. Gonds men I saw going to forests for timber collection more often than the Baiga men. When I tried to explore, one thing that came out distinctly was that Baiga men usually drink a lot of Mahua liquor whereas in Gonds, they have lesser usage. So Baiga men, don’t do well in agriculture and nor they go to forest to collect timber and support their family. So a woman has to perform lots of roles and also earn hard for the family.

4.1. I.Kadala village has 105 households out of which 80 of them belong to Gonds and they have a common lineage system. Around 10-12 houses belongs to Baiga tribe and the rest to Yadav.

5.1 Long term Memory:

Long term memory is the retention of facts or events that can be recalled even though they have not been continually rehearsed since their original presentation. These facts have been somehow represented in a relatively permanent state and have been remained stable during the retention interval. One important characteristic of long term memory is that it possesses an infinite capacity or ability to retain information.

There are times, however, when we are incapable of retrieving the information in this vast store house. Situations arise when we know that we have memorized some facts but simply cannot seem to recall it. It is almost as if something was blocking its retrieval. Eg: When I asked a villager, the name of her teacher, who used to teach them (since he was sharing about the how this teacher used to teach with so much of dedication) He was confused and was able to recall another teacher’s name, not this one.

Now, this “blocking” is what is known as “Interference” and this can be generated 2 ways. Either the material that interferes was learned before the information this villager was trying to recall or it was learned after it. If it was learned before, it is termed as “Proactive interference (PI)” and if it is after it is called “Retroactive interference (RI)”

There are 3 different ways measures which demonstrate how much material is retained. It is recall, retention and relearning. All these are basic ways, how our brain retrieves the memory of a particular event and shares.

6.1. Types of memories – Explicit & Implicit (Declarative and non-declarative) Episodic and Semantic with field data

Primarily memory has been divided into two. One is explicit (also known as Declarative) and Implicit (also known as non-declarative)

The type of memory that most closely matches the “store/retrieve” metaphor is “declarative memory”. There are two types of declarative memory: knowledge for facts and episodic memory (memory for past events). Another kind of memory is “procedural memory”, which is the learning of skills. The division of memory into implicit and explicit has been promoted by examining dissociation among tasks. Dissociation occurs when one variable (such as time) has a different effect on two different memory tasks.

Blaxton (1989) conducted few experiments that directly contrasted the predictions of an account based on a transfer-appropriate processing theory with a system account. It’s important to note that the structuralists & the processing frameworks make opposite predictions.  They discovered that two explicit tasks will differ from the two implicit tasks(regardless of the type of processing) whereas as the transfer appropriate processing account predicts that the two data driven tasks will differ from the two conceptually driven tasks ( regardless of the type of conceptual of conscious knowledge needed to perform the tasks.)

In general, the brain does not store new memories by a centrally controlled process, the way one might file something away in a file cabinet. Memory is a decentralized, distributed process in the brain. All parts of the brain are adapting to new information all the time. The main criteria the neural circuits use to decide when to alter them to accommodate new information is repetition. The more frequently two or more unusual pieces of information co-occur, the more the brain decides they must be important and prioritize them for associative retention by altering neural circuits. The brain does not really store “information” but rather adapts to statistical relationships among signals.
Another criterion by which the brain selects memory for storage is perceived value. If something unexpected happens, the brain records everything that led up to it. This process is mediated by the neurotransmitter dopamine, and is one of the reasons why dopamine-related drugs (cocaine, amphetamine) are addictive. This neurotransmitter controls the brains rewards and pleasure centres.

There is one region of the brain that is specialized for the formation of new declarative memories, and that is the hippocampus. Hippocampus is responsible for forming new memories and also helping in retrieving it at the time of recall. Several researches have been done on hippocampus’s role and function. There were experiments where a person’s hippocampus was removed and then doctors, discovered that he remembers everything of the past, but can’t form new memories.   This led to the realization that the hippocampus is specialized for the formation of new memories.

One current theory is that memories are coded temporarily by the hippocampus throughout the day, and then at night while we sleep (or dream?), the memories are transferred to the rest of the brain via a process called memory consolidation. The specifics of how this might work are still being investigated. Most recall occurs by association. An event or situation that is somehow similar to a memory from the past, or a piece of knowledge, causes that memory or knowledge to spontaneously re-enter consciousness. The spontaneous retrieval of memory by association is closer to a process of “reconstruction” than retrieval. Clues about a past mental state are activated until something coherent emerges. That coherent “recreated” brain state may or may not be an accurate reproduction of the past, as the high error rate of eye-witness testimony shows. The exact way that knowledge and episodic memories are coded and accessed is still the subject of on-going research.

 

6.1. a. Episodic and Semantic memory:

 

Episodic memory and semantic memory differ primarily in whether the rememberer is aware of the original learning episode.  Sharing a real example from the village of Kadala in Garhi-

E.g.: When I asked Saraswatiji (one of the lady in the village of Kadala where I was staying at her relative’s place) which was the crop that you harvested in the last summers? Being aware of the encoding episode suggests that the information is in the episodic memory. And she responded to me saying, “Rice” and then detailed out the entire process how did she and her family harvested together and how long did it take and so on.

Now in contrast, if she would have been an expert in farming and does lots of things related to agriculture and she “Knows” that they did harvest some crop but is unaware of the episode during which she acquired this information. In this case the information is in semantic (generic)

One way of examining the relative contributions of episodic and semantic memory is through a procedure called the remember/know paradigm.

(Source- Gardiner in 1988 and Tulving in 1985b)

In this procedure subjects are asked to give a “remember” response to all those items for which they can explicitly bring to mind the episode in which the item was learned. There must be conscious awareness of the specific learning episode in this case. However, if the subject thinks the item was on the list but can’t consciously recall learning that particular item in the learning phase, they are instructed to give a “Know” response.

 

Autobiographical memories are another set of memories that I found prominently active in this community. These are our recollections of circumstances and episodes from our own lives. Autobiographical memories encompass the episodic memories we hold about ourselves (Rubin, 1999; Sutin & Robins, 2007).

For example, we tend to forget information about our past that is incompatible with the way in which we currently see ourselves. One study found that adults who were well adjusted but who had been treated for emotional problems during the early years of their lives tended to forget important but troubling childhood events, such as being in foster care. College students misremember their bad grades—but remember their good ones (see Figure 5; Walker, Skowronski, & Thompson, 2003; Kemps & Tiggemann, 2007). Similarly, when a group of 48-year-olds were asked to recall how they had responded on a questionnaire they had completed when they were high school freshman, their accuracy was no better than chance. For example, although 61% of the questionnaire respondents said that playing sports and other physical activities was their favorite pastime, only 23% of the adults recalled it accurately (Offer et al., 2000).

It is not just certain kinds of events that are distorted; particular periods of life are remembered more easily than others. For example, when people reach late adulthood, they remember periods of life in which they experienced major transitions, such as attending college and working at their first job, better than they remember their middle-age years. Similarly, although most adults’ earliest memories of their own lives are of events that occurred when they were toddlers, toddlers show evidence of recall of events that occurred when they were as young as 6 months old (Simcock & Hayne, 2002; Wang, 2003; Cordnoldi, De Beni, & Helstrup, 2007).

Travellers who have visited areas of the world in which there is no written language often have returned with tales of people with phenomenal memories. For instance, storytellers in some preliterate cultures can recount long chronicles that recall the names and activities of people over many generations. Those feats led experts to argue initially that people in preliterate societies develop a different, and perhaps better, type of memory than do those in cultures that employ a written language. They suggested that in a society that lacks writing, people are motivated to recall information with accuracy, especially information relating to tribal histories and traditions that would be lost if they were not passed down orally from one generation to another (Daftary & Meri, 2002; Berntsen & Rubin, 2004).

 

The different stories and events that I could trace and classify into these 3 categories are below.

Episodic Memory (Declarative) Semantic Memory (Declarative) Procedural memory

(Non declarative) habits and skills

1. Agricultural practises and the crops they cultivate and harvest.

 

2. Marriage of their sons and daughters. What customs are followed in son’s marriage and how are they different from the daughter’s wedding?

 

3. Foraging routes and what all needs to be collected from the forest when they start their tasks.

 

4. The traditional folklores, songs, phrases and stories.

 

5. The lineage system and in their kinship who shares what relationship with whom.

 

6. They have a synchronic approach and often use an episodical memory for the different situations. For e.g.- They don’t remember their birth age and then will say, when I was small and when I was of my son’s current age and so on. There language reflects this during the conversations. E.g.- The last night for them is today’s night according to their TIME FUNCTION.  “Aaj raat sapna aaya tha…!!”

 

7. Episodical – In the earlier days, information source was only Radio and so everyone used to listen to radio, without failure. And people used to tell each other, if they come to know about something.  Now things have signicantly changed and people have different ways of information. Today TV, mobile, gram Panchayats all these serves as a major source of information channels to gain new information about agricultural seeds, new practices in farming, health care, mothers and child care information.

 

8.      Interview with a grandmother- 108 – Janani Express is accessible and everyone calls there and avails the facility. There are 4-5 Dais in the village who support the families in case of emergency if needed

1. Some traditional old stories :

 

Rains-Onset of monsoons -How do they predict?  Gadala plant (looks like an onion plants) in the forests, it gives flowers that blooms thrice in 3 months. The blooming of the flower in the 3rd month is the sign that now rain is going to start. This flower is a direct indicator for the onset of monsoons.                                                                                                                    2. Wind-  In the month of late  Jeth (Jeshtha) and early Ashaad, if the winds start blowing from the east direction in a continuous manner, one can make out that rains are going to come in next couple of hours.                                               3. Dumar fruit’s shape- According to the past stories, this fruit was round in shape and then once upon a time, a rat came and tried to taste it, and because the rat has tasted it, the shape of the fruit got distorted permanently and now its not round and looks like the mouth of the rat.  And all the animals, birds and humans eat it.

 

4. Interview from one of the villager: These people migrated almost 5 generations before and according to them this village is around 150 years old.                                                    These people don’t speak Gondi, but speak “Raigarhi” which is close to Hindi in some ways. They call is as their DEHATI language.

5. Interview with a grandmother earlier till 2000, the delivery was done in the villages only at homes. “Dai” was the lady who used to do it with the help of other women in the family.  Now a days, deliveries are done in the hospital. In emergency cases, they usually take the woman immediately to hospital to avoid complications.

1. Going to the forest and getting timber.

2. The villagers habit of urinating and defecating in the open.  They prefer to go out for urination and defecation. Usually they try to defecate near the forest areas, few meters away from their place of residence. For urination, they don’t have any criteria. They urinate in open, in their own farms nearby.

 

3. Most of the families consume “Mahua Liquor” Both males and females, drink them before the dinner. But now a days few families, they prefer not drinking.                                          Apart from Mahua Liquor, they also consumer their traditional drink names “Pej”

 

4. The villagers do believe that the person’s body is dead and he takes rebirth after some years and comes back to life. Because of their belief, they pray the fish (basically the shape) and pray the almight to help the soul take another birth in the same shape, which means the human form. In their culture “SHAPE and FORMS” have more importance.

 

There are instances where you might find that there is a combination or an overlap of semantic and episodic memory. Also there is a skill involved in it due to repeated action of the same over the years, and can be identified into procedural memory tool. An excellent example of that is the traditional ways of treating a person, if he or she breaks his or her bone. The remedy that they use is:

Frature or Bone Injury– Rangul creeper + mix it with Ghee and Honey. Add turmeric and any edible oil to it. Apply it on the injured part. the joint heals and the patient is recovered soon.

Plants of Mirmisi– Along with plant of Raajgonda, Dusa (carbon/Ash) Dried Red pepper, Coriander powder, Cream (Mahi in their local language) and Dahl. Mix all of them and feed the cattle if there is a Digestion problem. This is a very effective treatment, they use for their cattles.                                                                                                                                       In case of humans, if they have digestion problem, these people either take Mathha – made from butter milk. Milk is not readily available, so they have to get it from some other place. Pudina leaves are also used for cooling the body.

7.1 Relationship of working memory to long term memory and knowledge –

Working memory is not a special repository of information but rather a subset of declarative memory that is distinguished by higher activation cells. So whenever any information is retrieved that specific part is activated and it comes into action.

Memory trace- A prerequisite for any search is a collection of objects through which the search is to be made; in the present instance, the memory trace. A traditional approach defines these traces as a set of images or codes, where the structure of images is a function of the current task being utilized. Thus, if a series of paired associates is presented, the subject is presumed to store in memory a series of images, each representing a particular paired associate item. The memory search could then be said to take place through some subset of these images. The difficulty with this approach is that it is dependent upon the specific task and the type of test being used; it would be preferable to define the search upon a collection of objects that would not have to be altered with changes in the task and type of test.

A small example of the same is give below:

Organization of Long term memory into search-sets and image

Human brains are estimated to have a staggering 86 billion neurons with multiple connections from each cell webbing in every possible direction, forming the vast cellular network that somehow makes us capable of thought and consciousness.  With such huge number of connections to work with, it’s no wonder we still don’t have a thorough understanding of how the brain’s neural network operates. But the new mathematical framework built by the team of neuroscientists takes us one step closer to one day having a digital brain model. They found that groups of neurons connect into “Cliques” and that the number of neurons in a clique would lead to its size as a high- dimensional geometric object.

Algebraic topology, a branch of mathematics used to describe the properties of objects and spaces regardless of how they change shapes. This is very important for us to understand and build more insight as foraging behaviour deeply engages with objects in the form of forest produce and spaces in from of the mental maps that they have of the different foraging route imprinted within their brains.

Algebraic topology provides mathematical tools for discerning details of the neural network both in a close up view at the level of individual neurons and a grander scale of the brain structure as a whole.  By connecting these 2 levels, the researchers could discern high-dimensional geometric structures in the brain, formed by collections of tightly connected neurons (cliques) and the empty spaces (also called cavities) between them.  (Source- Kathryn Hess, Frontiers of Computational Neuroscience )

It has been found through researches and various studies that there are remarkably high number and variety of high- dimensional directed cliques and cavities, which had not been seen before in neural networks, either biological or artificial.  Through the algebraic typology one can zoom into the networks to find hidden structures, the trees in the forest and see the empty spaces, the clearings, all at the same time.  Those cavities/clearings seem to be critically important for brain function. When researchers gave their virtual brain tissue a stimulus, they saw that neurons were reacting to it in a highly organised manner.

This also helps us relate to the fact, that foraging activity and the various challenges (any new stimulus) that the villagers encounter within the forest during foraging.  The brain reacts to a stimulus and then starts building a block in the form of a tower. These processes continue and these blocks keep on piling within the brain like geometric structures.  Few examples from the village Kadala, where I conducted my Research study are given below:

Challenges Tasks
1. Walking for hours together in the forest, collecting timber and other forest produce.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2. Cutting the timber and other branches of the trees like mahul and others.

 

 

 

 

 

 

 

 

3. Animals in the wild like big cats, sloth bears and swamp deer.

 

1. They usually prefer early mornings or late afternoon timings to go in the forest.                                                         2. They go in groups of 5-6 or 4-5 people at a time. Nobody goes alone because of the risks that have to face.                                                                             3. They follow a filing system in which they walk one behind the other in a way that one cannot see any other person, apart from the person who is in the front. This discipline helps them to run and make fast decision if they encounter any wild animal.                                                 4. The group has some major landmarks within the forest, where they depart from the group and start collecting timber and other stuff as an individual. They again meet at another common point and then start organizing their forest produce in a way that they would be able to carry it over their heads.

 

 

 

1. They don’t use any tool like hammer and axe. Earlier they used to keep all these tools inside the forest but now, because of strict forest laws, all this is strictly prohibited. So, they use their hands for cutting, tying, folding and for other functions.

2. Their motor skills are quite advanced and one can see it clearly when they start organizing their forest produce in one big load. They also climb the trees if needed. They exactly know which tree to climb and for what?

 

1.  They remain alert while taking every step and they know from the smell and sounds if there is some wild animal in the vicinity. They also take their children along to have some more safety and a supporting hand.

 

Summary:

jj.jpg

My Research study and observation showed that the people of Kadala have a good episodic memory and that have a good mix of semantic and procedural memory. The way information is passed on from one generation to other, is by and large oral whether it’s the different family rituals, birth of a new born baby, death rituals, daily work chores and their detailing, songs and folklores, historical facts, ancient beliefs and myths, superstitions related to horoscopes and so on. The written culture is not so popular but there is a 20-25% population (roughly) who understands the value of education and also writing things facts and figures. It was interesting for to understand that written knowledge for them was important to understand the legal records related to farming and different government schemes.

From the foraging data, it also shows that Baiga’s who go quite deep within the forests and spends more time in the foraging act than the Gonds; tend to have more complex mental maps of the forest. It will be interesting to see, if this knowledge is replicated in their children too, when they join their parents during foraging. It’s also quite evident from the study that for Gonds foraging is an activity that take care of their daily needs of timber, food and daily items like brush and broom, whereas for Baiga’s is a way to meet their  livelihood needs.  Both the tribals (Gonds as well as Baigas) own good agricultural land, but in Kadala Gonds men and women both do farming and work hard whereas in Baiga’s (who are around 10% of the total population) only women put in more efforts. Men drink mahua and half of the time during the day, they are sleeping. Baiga women are extremely hard working and have to manage work, family and daily chores all at different levels whereas for Gond women they get support from their men.

Memory traces also have given some insights that Gonds and Baigas in this community have good explicit (declarative)   memory but an excellent implicit memory. This also indicates that habit formation and skill building takes place at a very early age due to which they have a strong ability to exhibit it and so they are excellent with their implicit memory.  For explicit memory, one has to recall the evidences often in order to retain them, and very few can do it in an efficient manner. Also for explicit memory, if you don’t know you can always go and take help from your relatives and nearby family members.

Quest to know more- Sairat..!! The journey of life, leading to ……..?

Review of the Movie:

 

Watched this movie a month back and then heard from so many friends, colleagues and relatives. Yes, no doubt everyone enjoyed the movie and it had many subtle questions for the society and addressed the key issue of why it is so important to talk to families and share with them, before taking an extreme action.

The film follows the story of Parshya, a low-caste man, and Archie, a daughter of a rich “upper caste landlord”, who falls in love despite pressures from society that they must not be together. When their relationship is discovered, the couple is faced with violence and many challenges before they leave for the city.  The movie’s first part deals with a romantic love shades where there is lot of naughtiness seen, young love bubbling up and adolescents immersed in pure madness of sheer love and happiness. Excellent acting by both the actors. Even the starting plot was very well laid by the director, where he is bringing about many issues of the village and the society through  the “”Cricket” match.

Whereas the second part is more about the very struggle both of them faced and then emerged as a powerful family. They overcome their situations, learnt from their hardships and also lived the life they wanted to live. Till that it was fine, but the moment the parents come to know about them, they ensure they both of them are killed and they are successful in doing that.

Definitely the story could have been reduced in terms of its length, where many unnecessary prolonged shots have been taken.  Songs, Music and Lyrics are at the top no doubt and make you feel dance and sing.  Now, besides the technical parts of movie making, I want to highlight some basic questions, which came to my mind, while watching this movie:

 

  • Movies are the stories that come from our society. And there is a huge audience that get influenced by such love stories and where do you mark a line, when it’s a PURE LOVE.
  • Treating such stories also means that one has a responsibility to deal with the topic sensitively. Somewhere down the line, it felt as if ONE WAS PUNISHED FOR FALLING IN LOVE…..!!
  • The climax, may also justifies conservative people who still believes in casteism and advocate classes within the society. How do we help them REFLECT on this? The movie is somehow reaffirming their beliefs more strongly.
  • The whole approach of this movie, at the end somewhere, reflects that if you don’t let you parents know about things and don’t take their agreement into account, something similar can happen which is as extreme as this movie has shown?
  • Both the girl and the boy study in the same college and the guy is shown more intelligent in a way, but just because he is not rich and well settled, in the later stages is shown working as vendor body and as a labourer whereas the girl, who is from a rich family gets a managerial job. Are we trying to give some MESSAGE THROUGH THAT?
  • How do we see LOVE and the universal force that binds us? Parents love is more than anything, why is blockage is there in our minds? Is love really a comparable commodity to think?

My Take:

images (2)

  • Could have enjoyed if the director would have posed some question/questions at the end of the movie, to the audience and society related to what they think? It could have led to a mass movement towards breaking these stereotypes, caste and class debates because media is a strong way of bringing about social changes.
  • A positive message where parents share their disappointment and never come along with them, rather than taking such an extreme step / where parents come along and share love together with their family of Archie and Pasrshya…!!

LOVE STORY – And at the end its the love..!! 

The movie somehow gave a feeling of tornness and hurt at the end. 

Creative Assembly in “Girirajpura School”

Morning Assembly at Girirajpura School:

We all remember during our school days and how we used to start our day with an assembly. There used to me a prayer song, followed by some news bulletin, current affairs and some exercises. It was quite amazing to see and visit Girirajpura School, which is almost 40 kms  away from the main SawaiMadhopur city where, each child shared his or her input and then co create an assembly session. They sing, dance, talk and discuss about issues related to their school,community and classroom, cleanliness and hygiene related matters and so on. All this becomes a part of the Assembly and this platform, is something which is an important part of the school’s every day rituals.

Phenomenal Palace and Me- “Lakshmivilas”

Incredible Lakshmivilas Palace- Vadodara-

It was not in my life, that I plan too much for things and then make them happen. So, visiting to Vadodara, was much like this. I had few cousins staying over there and then when I got a weekend, I thought of visiting them. It was just an amazing time I had with them and since I love to visit the nearby places, I decided to go to Laxmivilas Palace, about which I have heard a lot in the last 15-20 years.The best thing about this palace is that it is still a living palace which means, that still the Gaekwad family stay there in one part of the palace. Its a home for them. This is not usually seen in other palaces, where they are kept just for visits and maintenance. One can make out, how different one feels, when one enters someone’s home, which is a palace itself and how those energies are felt all around.

“Incredible piece of Art and Creativity indeed”

My niece, Namita, came along with me and we really had some really enriching, wonderful and incredible experience. I never thought that this palace is so huge. Being in Rajasthan, I had visited to many palaces and so I was not really thinking this to be an incredible and marvellous piece of art.When you see it from outside, it look like a massive giant palace with enormous facets and when you go closer the massiveness becomes eye catching and mesmerizing in its own ways. Whether its paintings, or wall hangings, gardens or architecture, weapons collection or handmade things, hunting tiger or deer skins or the mehfil khana all just makes you feel speechless.

03-DSC_082804-DSC_0835

We left early morning, had our breakfast, shared some stories of our work and then left to visit the palace. Namita, already knew a lot about this palace from the beginning, so she endlessly continued to share stories from the past about the prince, the Gaekwad family and their ancestral anecdotes one after the other. She was quite informative that way and being a localite it was an added advantage. This is my experience that more, you are familiar to the place, more comfortable you become and if you have a local person with you, there is nothing like it. It adds on to your comfort and also well-being in a great way. I really admire Namita and her warm presence around me. She must have visited this place 100s of times, but her curiosity to be a child, and her willingness to share things with me, were something that I relished beyond measures.  She has an impeccable command over the stories of the past related to Gaekwad Gharana. What I  loved about the palace was the audio system, which helped to listen to stories and information in a great details.

The term Maharaja Palace actually refers to a series of palaces in Vadodara, Gujarat, India, constructed since the Gaekwad a prominent Maratha family started ruling the Baroda State. The first one was a building known as the Sarkar Wada. This building, not really a palace, was given up for the Nazarbaug Palace built in old classical style. This palace was built by Maharaja Sayajirao Gaekwad III in 1890.I was really mesmerized by the way the whole architecture was done. In those days ,when technology was not there, when it was difficult to communicate to each other in that era, something so beautiful, unimaginable palace like this was built. Really feels hats off to the workers, laborers and everyone who had contributed to this, due to which today we area able to see some great structures like this.

Long shot taken from a distance by me.

It is reputed to have been the largest private dwelling built till date and four times the size of Buckingham Palace. At the time of construction it boasted the most modern amenities such as elevators and the interior is reminiscent of a large European country house. It remains the residence of the Royal Family, who continue to be held in high esteem by the residents of Baroda.

Darbar Hall featuring the Rajas Throne: This was simply marvellous. My eyes are stuck on the kind of artistic work that was done and that too in those days.

36-DSC_0902

Darbar hall featuring the Ornate artwork:Its ornate Darbar Hall, which is sometimes the venue of music concerts and other cultural events, has a Venetian mosaic floor, Belgium stained glass windows and walls with intricate mosaic decorations.This is the same place where “Prem Ratan Dhan Payo” movie was shot in 2015. The place was dedicated for Mehfils by renowned poets, musicians and dancers of those times. The females of the palace, used to see this mehfil from the top windows. They were not allowed to come down and be a part of the larger community. The were considered special and were not given the same treatment as men.

27-DSC_0874Outside of the Darbar Hall is an Italianate courtyard of water fountains. The palace houses a remarkable collection of old armoury and sculptures in bronze, marble & terracotta by Fellici. Each stone/marble was imported through different parts of the world, through water transport. The palace is full of Italian, Russian, Indo-western styles of architecture.   The grounds were landscaped by William Goldring, a specialist from Kew Gardens. The Palace “compound” covers over 700 acres (2.8 km2) and houses a number of buildings, particularly the Moti Baug Palace and the Maharaja Fateh Singh Museum building.

29-DSC_0883

This was one of the unimaginable place with absolute peace and quiet ambience. What more you need? 

When I entered this place I really thought, why there is not water source here, and the moment I reached to this fountain space,I was on the top of the world. Water, is one thing I have loved the most and still love it. The cleanliness in and around the palace is something, I really wish to share about. The toilets were in very good condition, neat, clean and tidy with water facility. This also speaks about how our culture was and what we have made it like today.

31-DSC_089532-DSC_0896.JPG

The Museum building was constructed as a school for the Maharaja’s children. Today a large number of works of art belonging to the Royal family have been displayed in the museum. The most remarkable of these is the fabulous collection of the paintings of Raja Ravi Varma, who was specially commissioned by the then Maharaja of Baroda. The collection includes portraits of the Royal family in addition to the paintings based on Hindu mythology for which Raja Ravi Varma was famous.

The charm and convenience to hear the stories with the help of technology is really an innovative way.

Encounter with “DHOLE” (Wild dogs)

 

 

 

DSC_0335

A young  confident and bold “Dhole” on his way leading the group.

I have been travelling to these forest and tiger reserves from almost a year and a half. And though I don’t go in the core so often, there is this unsaid anxiousness to just keep your fingers crossed and imagine some wild animal approaching you. It all about the crazy imagination of a person, who is fond of nature and its diversity. And so this time, during my visit to Tadoba Tiger Reserve, I encountered a pack of 7 wild dogs. I had always heard that wild dogs are always in groups and they are more dangerous than Big Wild cats at times. I was furious to see them, but then somehow came out of my vehicle and captured.

It was around 7.30 am in the morning and I was going through the Tadoba’ s  buffer zone (forests) along with my driver and the coordinator where I saw a pack of wild dogs sitting on the side of the road. They all were quite in their own play way mood. Wild dog is a highly social animal, living in large clans and containing multiple breeding females. It is a diurnal pack hunter which preferentially targets medium and large sized ungulates. In tropical forests, the dhole competes with tigers and leopards targeting somewhat different prey species, but still with substantial dietary overlap.

It was a quite an interesting morning to start the day with work. We moved to the NFE, taking the amazing memories of the Wild dogs with us.

POWER OF 1% OVER 99%

When it comes to “LEARNING” and “CONNECTING WITH YOURSELF”

 And we say that man learns through books, television and internet but the best of the learning has happened to me only through my experiences of life. Definitely the formers have influenced me to a great extent in the way I think and exhibit my response to situations but most of it is merely through experience.

 

IMG_20150106_080947

 

The journey of experiential education also came in my life, with this subtle realization as a young girl, looking at life and its huge canvas. Looking at people, following their dreams and yet learning in their own ways and putting their ideas in place, really gives me a feeling of self-contentment and encouragement.

This is an experience of my life, which I want to share, to connect with those souls, who had experienced something similar in their lives in the past. It was somewhere at night when I was on my way back home and suddenly when in a meditative phase. I was a bit tired and wanted to relax for a while. When I closed my eyes, I could sense a lot of negativity in my mind and I was recalling some viscous painful memories that were juxtaposing over each other in an endless manner. I was getting overwhelmed and wanted to be at peace and in isolation for some time. And I did the same.

The more I tried to go away from it; more I was getting closer towards it. Slowly there was something BEAUTIFUL that happened the moment I realized that though everything is negative and low in energy, there is a small part within me which is blowing, growing and is happy and I was wondering why it is happening? It was magical and unimaginable. I was surprized to see how it was growing and expanding from within. Slowly, that small part made me realize how happy and blessed I am? How this small beauty touched me, made me realize that all those pains, struggles and sadness was just another part of me, which was somewhere needing a place to rest and reflect itself. It was longing for acknowledgement and a sense of liberty to express itself the “”WAY IT IS.”  Those experiences have taught me few things:

  • To be more grounded and be mindful.
  • To acknowledge life with both its facets.
  • Be alert and conscious, because in the most painful experiences of life also, there will a small beam of light, which will take you to the path of consciousness.
  • Pain has its own beauty and its needs to be acknowledged and appreciated.

That incidence made me realize the power of 1% over the 99% which was more in terms of numbers and intensity but had an energy that was pushing me down and was also asking me to “LET GO” and feel it completely till it’s done.  1% was just there, but was not visible. It needed some extra efforts, some patience and perseverance that certain things happen at their own pace.

It was a wonderful discovery that happened to me while travelling. I don’t know what others think about it and how it lands for them, but for me it gave a “SENSE OF HOPE” and energy to move ahead.
