- Learning shapes human behavior by changing our nervous system and behavior based on experiences. We call these changes memories.
- There are four basic forms of learning: perceptual learning, associative (S-R) learning, motor learning, and relational learning. Learning involves forming connections between neurons based on experiences.
- Memories can last from seconds to years in different memory systems like short-term and long-term memory, which are supported by different brain regions like the prefrontal cortex and hippocampus.

Definition
Our ability to encode, store, retain and subsequently recall information and past experiences in the human brain.It is the sum total of what we remember, and gives us the capability to learn and adapt from previous experiences as well as to build relationships.
In more Physiological and neurological term, memory is, at its simplest , a set of encoded neural connections in the brain.
MEMORY PROCESS
1)Encoding
2)Storage
3)Retrieval
NEURO-BIOLOGY OF ENCODING
Process of laying down a memory begin with attention, which is regulated by thalamus and fontal lobe, in which a memorable event causes neurons to fire more frequently making the experience more intense and increasing the likelihood that the event is encoded as a memory. Emotion increases attention in the amygdala. The perceived sensation are decoded in the various sensory areas of the cortex. Then combined in the hippocampus into one single experience. Hippocampus analyzing these inputs and ultimately deciding if they will be committed to long- term memory.
TYPES OF MEMORY
1)Sensory memory
2)Short term memory
3) Long term memory
MODELS OF MEMORY
1) ALLEN D. BADDELEY’S MODEL
2)ATKINSON AND SHIFFRIN’S MODEL (1968)
3)LEVELS OF PROCESSING ( CRAIK AND LOCKHART)

Bluma Zeigarnik , a Russian Psychologist, compared memory for tasks that were successfully completed and those which were not. She interpreted the work and did not allow them to finish it. Interrupted tasks were remembered more frequently than those which were completed.
Dutta and Kanungo gave a new interpretations to this effect.
The intensity of emotiom arousal by the completed tasks or the interrupted task is the critical factor. Any aivity that gives to strong emotion, be it pleasant or unpleasant , is remembered better than ordinary everyday actions
METHODS OF STUDYING MEMORY

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

behavior. From the classroom to
the trading floor to ordering at a
restaurant, our ability to make
good decisions is shaped by how
we learn from experience.”
-Daphna Shohamy
Biology of Learning and Memory
2. 13 Learning and Memory
What is the nature of learning?
Learning is the process by
which experiences change
our nervous system, and
hence our behavior.
We call those changes
memories.
3. 13 Overview
Four basic forms of learning:
• Perceptual learning
• S-R (associative) learning
• Motor learning
• Relational learning
5. • Neurobiologists
generally believed that
memories were
generally not the result
of new neuron
production
• 1894: Santiago Ramon
y Cajal thought
memories were formed
by strengthening
neuron connections
• 1949: Hebbian theory
13 Early Learning Theory
7. • Changes in the structure or biochemistry
of synapses that alter their effects on
postsynaptic neurons
• Long-term Potentiation: long term
increase in the excitability of a neuron to a
particular synaptic input caused by
repeated high-frequency activity of that
input.
• Long-term Depression: produces a long-
lasting decrease in synaptic strength.
13 Synaptic Plasticity
8. • Associative long-term potentiation:
weak synapses are strengthened by the
action of strong synapses
• NMDA receptor: A specialized ionotropic
glutamate receptor that controls a calcium
channel that is normally blocked by Mg2+
ions; involved in long-term potentiation.
• AMPA receptor: An ionotropic glutamate
receptor that controls a sodium channel;
when open, it produces EPSPs.
13 Synaptic Plasticity
9. 13 Perceptual Learning
• Involves learning to recognize things, not what
to do when they are present
• Can involve learning to recognize entirely new
stimuli, or it can involve learning to recognize
changes or variations in familiar stimuli
• We learn that particular stimuli are found in
particular locations or contexts or in the
presence of other stimuli. We can even learn
and remember particular episodes: sequences
of events taking place at a particular time and
place.
10. • Thalamus LGN -> primary visual cortex ->
extrastriate cortex
• Objects are recognized visually by circuits
of neurons in the visual association cortex.
• Damage to the inferior temporal cortex
leaves vision unaffected but causes
inability to discriminate visual stimuli
• Ventral = what, Dorsal = where
13 Perceptual Learning
11. • Involves changes in synaptic connections
in the visual association cortex , creating
new neural circuits
• When exposed to the same stimulus, the
same circuits become active
13 Perceptual Learning
14. • MT/MST: region of the visual association
cortex that perceives movement
• Memory contains information about
previously seen movements
• Brain saves sensory information for future
reference
13 Perceptual Learning
15. • The memory for a stimulus or an event
that lasts for a short while
• Involves activating established neural
circuits even after stimulus is gone
• Delayed matching-to-sample task: A
task that requires the subject to indicate
which of several stimuli has just been
perceived.
13 Short-term Memory
17. • Involves several brain regions
• Prefrontal cortex manipulates and
organizes information to be remembered
• PFC devises strategies for retrieval and
monitors the outcome of those processes
• Successful remembering requires: filtering
out irrelevant info and maintaining relevant
info
13 Short-term Memory
19. 13 S-R Learning
Hebb’s rule: Neurons that fire together, wire together.
S-R Learning is to learn to perform a particular
behavior when a particular stimulus is present
20. Ivan Pavlov
While studying salivation in
dogs, Pavlov “stumbled”
upon the principles of
classical conditioning.
13 S-R Learning
21. In classical (Pavlovian) conditioning, a neutral
stimulus is paired with another stimulus that elicits a
response.
Eventually, the neutral stimulus by itself will elicit the
response.
13 S-R Learning
25. B.F. Skinner
13 S-R Learning
He was a firm believer
that any human action
was the result of the
consequences of that
same action.
26. In instrumental
(operant) conditioning,
an association is made
between:
• Behavior (the
instrumental response)
• The consequences of
the behavior (the
reward).
13 S-R Learning
28. The Reinforcement System
13 S-R Learning
Detect the presence of
a reinforcement
stimulus.
Strengthen the neural
connections between
the discriminative
stimulus and the
instrumental response.
32. • Iconic memories are the briefest
memories and store sensory impressions
that only last a few seconds.
• Short-term memories (STMs) usually last
only for up to 30 seconds or throughout
rehearsal.
Short-term memory is also known as
working memory.
13 Memory
I work out!
33. • An intermediate-term memory (ITM)
outlasts a STM, but is not permanent.
• Long-term memories (LTMs) last for
days to years.
13 Memory
34. 13 Relational Learning
Henry Molaison suffered
from severe epilepsy.
Because of seizures, a
decision was made to
remove the amygdala, the
hippocampus, and some
cortex.
Patient H.M.
35. • Retrograde amnesia
is the loss of memories
formed before onset of
amnesia and is not
uncommon after brain
trauma.
• Anterograde amnesia
is the inability to form
memories after onset
of amnesia.
13 Relational Learning
H.M. had normal short-term
memory but had severe
anterograde amnesia.
36.
37. Dissociation of explicit (declarative) memory, which
was impaired vs.
Implicit (nondeclarative) memory, which was fine
13 Relational Learning
38. • Declarative memory
deals with what—facts
and information acquired
through learning that can
be stated or described.
(Things we are aware that
are learned.)
• Nondeclarative
(procedural) memory
deals with how—shown by
performance rather than
conscious recollection.
13 Memory
Two kinds of long-term memory:
