I now have rich material from the textbook and web sources. Let me compile the most detailed, exam-ready notes possible.
THEORIES OF LEARNING - Detailed Exam Notes
PART 1: BEHAVIOURISM
What is Behaviourism?
Behaviourism is a school of psychology that says learning = a change in observable behaviour caused by environmental stimuli. It completely ignores internal mental states (emotions, thoughts, feelings) because they cannot be observed or measured. The mind is treated as a "black box."
Core Belief: "Tell me the stimulus, I'll tell you the response."
The learner is viewed as passive - a blank slate (tabula rasa) shaped entirely by the environment through experience.
A. Classical Conditioning (Ivan Pavlov, 1890s)
The Story Behind It
Pavlov was a Russian physiologist studying digestion in dogs. He noticed that dogs began salivating before food arrived - just at the sight of his white lab coat or the sound of footsteps. This accidental discovery launched one of psychology's most important theories.
The Mechanism - Step by Step
BEFORE CONDITIONING:
Food (Unconditioned Stimulus / UCS) ──→ Salivation (Unconditioned Response / UCR)
Bell (Neutral Stimulus / NS) ──→ No response
DURING CONDITIONING:
Bell (NS) + Food (UCS) ──→ Salivation (UCR)
[Repeated many times together]
AFTER CONDITIONING:
Bell alone (Conditioned Stimulus / CS) ──→ Salivation (Conditioned Response / CR)
The dog has learned to associate the bell with food. The bell now predicts food, so it triggers the same response.
Key Terminology Explained
| Term | Simple Definition | Example |
|---|
| UCS | Stimulus that naturally produces response | Food |
| UCR | Natural, automatic response | Salivation to food |
| NS | Originally neutral, no response | Bell |
| CS | Previously neutral; now triggers response after pairing | Bell after conditioning |
| CR | Learned response to CS | Salivation to bell |
Important Phenomena in Classical Conditioning
1. Acquisition - The period during which the association is being learned. Stronger if the NS is presented just before the UCS (not after or simultaneously).
2. Extinction - If the CS is repeatedly presented WITHOUT the UCS, the CR gradually weakens and disappears.
- Example: Ring the bell 50 times without food → dog eventually stops salivating.
3. Spontaneous Recovery - After extinction, if you wait a while and then present the CS again, the CR reappears weakly.
- Example: A week after extinction, ring the bell → dog salivates briefly again.
4. Generalisation - The CR is triggered by stimuli similar to the CS.
- Example: Dog conditioned to a 1000Hz bell also salivates to a 900Hz or 1100Hz bell.
5. Discrimination - The organism learns to respond only to the specific CS, not to similar stimuli.
- Example: Dog learns bell = food, but metronome = no food; stops generalising.
6. Higher-Order Conditioning - A new NS is paired with an already established CS (not the original UCS).
- Example: Bell (CS) is paired with a light → light alone eventually triggers salivation.
Real-Life Examples of Classical Conditioning
- Dental anxiety: The smell of a dental clinic (NS) is repeatedly paired with pain (UCS). Soon the smell alone causes anxiety (CR).
- Advertising: A beautiful model (UCS → positive feelings UCR) is shown next to a car (NS). Over time, seeing the car alone creates positive feelings (CR).
- Drug cravings: A person who takes heroin in a specific room associates that room (CS) with the drug effect. Just entering that room triggers cravings (CR). This is used to explain relapse.
- Phobias: John Watson's Little Albert experiment - a 9-month-old baby was shown a white rat (NS). Each time the rat appeared, a loud bang (UCS) was made. Albert soon cried (CR) at the sight of the rat alone - and generalised this fear to white rabbits, Santa's beard, fur coats.
Watson's Behaviourism - "Give me a dozen infants..."
John B. Watson (1913) declared psychology must only study observable behaviour. His famous (controversial) quote: "Give me a dozen healthy infants...and I'll guarantee to take any one at random and train him to become any type of specialist I might select - doctor, lawyer, artist..." - illustrating extreme environmentalism.
B. Operant Conditioning (B.F. Skinner, 1938)
Key Difference from Classical Conditioning
| Classical Conditioning | Operant Conditioning |
|---|
| Type of behaviour | Involuntary/reflex | Voluntary |
| How it works | Stimulus precedes response | Consequence follows response |
| Learner's role | Passive | Active |
| Example | Salivating to bell | Pressing lever for food |
The Skinner Box
Skinner placed a rat in a specially designed box (operant chamber). The rat explores randomly. Accidentally, it presses a lever → food pellet drops. Rat presses more. It has learned: behaviour operates on the environment to produce consequences.
The Four Quadrants of Operant Conditioning
Think of it as a 2x2 matrix:
- Positive = Adding something
- Negative = Removing something
- Reinforcement = Increases the behaviour
- Punishment = Decreases the behaviour
| Increases Behaviour | Decreases Behaviour |
|---|
| Add something | Positive Reinforcement | Positive Punishment |
| Remove something | Negative Reinforcement | Negative Punishment |
Detailed Examples of Each
1. Positive Reinforcement (Add pleasant → behaviour increases)
- Child answers a question correctly → teacher gives praise → child answers more in future
- Student gets an A grade → feels proud → studies harder next time
- Dog sits on command → gets a treat → sits more often
2. Negative Reinforcement (Remove unpleasant → behaviour increases)
⚠️ Most commonly confused concept in exams. Negative reinforcement is NOT punishment - it INCREASES behaviour.
- Wearing a seatbelt (behaviour) → annoying beeping stops (removal of unpleasant) → you wear it more often
- Student studies (behaviour) → anxiety about failing is reduced → studies more
- Taking painkiller (behaviour) → headache disappears → takes painkiller more readily next time
3. Positive Punishment (Add unpleasant → behaviour decreases)
- Child misbehaves → gets extra homework → misbehaves less
- Driver speeds → gets a fine → speeds less
- Touch a hot stove → pain → avoid touching it
4. Negative Punishment (Remove pleasant → behaviour decreases)
- Teenager breaks curfew → phone is taken away → breaks curfew less
- Student talks in class → loses free period → talks less
- Child throws a tantrum → is removed from play → tantrums decrease
Schedules of Reinforcement (Very Important for Exams)
The timing of reinforcement affects learning dramatically.
| Schedule | How It Works | Effect | Real-Life Example |
|---|
| Continuous | Reinforce every single time | Fast learning, fast extinction | Vending machine - every coin gives snack |
| Fixed Ratio (FR) | Reinforce after a fixed number of responses | High, steady rate; pause after reward | Paid per 10 items packed in factory |
| Variable Ratio (VR) | Reinforce after unpredictable number of responses | Highest and most resistant to extinction | Slot machines, fishing, social media "likes" |
| Fixed Interval (FI) | Reinforce after a fixed time period | Scallop pattern - slow then burst | Monthly salary, weekly test |
| Variable Interval (VI) | Reinforce after unpredictable time periods | Slow, steady, persistent responding | Checking email - reply comes randomly |
Key Exam Point: Variable Ratio is the strongest schedule - explains why gambling is so addictive and hard to stop.
Other Important Operant Concepts
Shaping: Reinforcing successive approximations to the desired behaviour. You reward steps that get closer and closer to the goal.
- Example: Teaching a child to write - first reward holding the pen, then making marks, then letter shapes, then actual letters.
- Clinical use: Teaching speech to a non-verbal child with autism.
Chaining: A series of behaviours, each one linked to the next, with the final behaviour being reinforced.
- Example: Getting dressed - underwear → shirt → trousers → shoes → all steps are chained; the final reward is going outside to play.
Token Economy: Tokens (points, stickers, chips) are earned for desired behaviour and exchanged later for real rewards.
- Used in: Psychiatric wards, special education, substance abuse programs, children's classrooms.
Extinction in operant conditioning: Stop reinforcing a behaviour → it gradually decreases.
- Example: Teacher stops acknowledging a student's attention-seeking behaviour → behaviour eventually stops.
Punishment vs Reinforcement - Key Exam Distinction:
- Reinforcement (positive or negative) always INCREASES behaviour
- Punishment (positive or negative) always DECREASES behaviour
Thorndike's Law of Effect (Historical Foundation)
Thorndike placed a cat in a "puzzle box." The cat scratched randomly and eventually hit a lever to escape. With repeated trials, the cat escaped faster - it learned which behaviour "worked."
- Law of Effect: Responses producing satisfying outcomes are strengthened (stamped in); responses producing discomfort are weakened (stamped out).
- Law of Exercise: Responses that are practised are strengthened.
Criticisms of Behaviourism
- Ignores internal mental processes - emotions, thoughts, memory
- Most evidence from animal studies - oversimplified generalisation to humans
- Cannot explain language acquisition (Chomsky's devastating critique of Skinner)
- Dehumanises the learner - treats people like rats
- Does not explain latent learning (Tolman showed rats learn mazes even without reward)
- Cannot explain insight learning (Kohler's chimpanzees solved problems suddenly)
PART 2: SOCIAL LEARNING THEORY (Albert Bandura, 1977)
Core Idea
Bandura argued that Skinner's behaviourism was incomplete because it ignored the mind. People do not just respond to direct rewards and punishments - they watch other people (models) and learn from what they observe. This is called observational learning or modelling.
Bandura's key position: Learning occurs in a social context and involves both behaviour AND cognition (thinking). He called his updated version "Social Cognitive Theory."
The famous formula:
Reciprocal Determinism: Behaviour ↔ Personal Factors (cognition, emotions) ↔ Environment (all three constantly influence each other)
The Bobo Doll Experiment (1961) - The Classic Proof
Bandura divided children into three groups:
- Group 1: Watched an adult model beat up a Bobo doll aggressively (hit it, kick it, yell at it)
- Group 2: Watched a non-aggressive adult ignore the doll
- Group 3: Saw no adult (control)
All children were then mildly frustrated and left alone with the Bobo doll.
Result: Group 1 children showed significantly more aggression - they copied the adult's exact actions and words. They had learned aggression without any direct reinforcement.
Further finding (1965): When the aggressive model was rewarded for hitting the doll, children imitated even more. When the model was punished, children imitated less. This demonstrated vicarious reinforcement/punishment - learning from the consequences experienced by others.
The Four Processes of Observational Learning
For observational learning to occur, ALL four must be present:
1. ATTENTION 👁️
You must notice and observe the model's behaviour.
- Factors that increase attention: model is attractive, similar, high-status, competent, or the behaviour has important consequences
- Example: A medical student pays close attention when a senior consultant demonstrates how to take a blood pressure reading.
- If a learner is distracted, drowsy, or the material is complex, attention drops and learning fails.
2. RETENTION 🧠
You must be able to remember what you observed.
- Memory is encoded using symbols, language, and mental images
- Example: The student mentally rehearses the steps of BP measurement after watching.
- Factors: repetition, chunking information, using mental imagery
3. REPRODUCTION (Motor Reproduction) 🤸
You must be physically and cognitively able to reproduce the behaviour.
- You may have watched someone play concert piano perfectly, but if you lack the motor skills, you cannot replicate it immediately.
- Example: A student must practice venipuncture themselves - just watching is not enough to develop the hand skill.
- Practice improves reproduction; self-observation and feedback help refine it.
4. MOTIVATION 💪
You must want to perform the behaviour.
- No matter how well you attended, retained, and can reproduce - without motivation, you won't do it.
- Motivation comes from:
- Direct reinforcement: You get a reward for performing the behaviour
- Vicarious reinforcement: You saw the model get rewarded → you want the same
- Vicarious punishment: You saw the model get punished → you avoid the behaviour
- Self-reinforcement: You reward yourself internally ("I did well - I'm proud")
Self-Efficacy - Bandura's Greatest Contribution
Self-efficacy = A person's belief in their own ability to successfully perform a specific task in a specific situation.
This is NOT the same as self-esteem (general self-worth) or self-concept. It is task-specific and situation-specific.
Four Sources of Self-Efficacy
1. Mastery Experiences (most powerful)
- Successfully completing a task → raises self-efficacy
- Failing → lowers it
- Example: A student who passes their first anatomy exam feels more confident about the next one.
2. Vicarious Experiences (modelling)
- Watching someone similar to you succeed → raises your belief that you can too
- Watching someone similar fail → lowers it
- Example: "If my classmate who also struggled with chemistry passed, so can I."
3. Social Persuasion (verbal encouragement)
- Being told "you can do this" by a trusted person raises self-efficacy
- Criticism or discouragement lowers it
- Example: A teacher telling a nervous student "I've seen your work - you're ready for this exam."
4. Physiological/Emotional States
- Feeling calm and relaxed → higher self-efficacy
- Heart racing, hands shaking, feeling anxious before a test → lower self-efficacy
- Example: Learning relaxation techniques before exams can boost self-efficacy.
Why Self-Efficacy Matters in Education
| High Self-Efficacy | Low Self-Efficacy |
|---|
| Sets challenging goals | Avoids difficult tasks |
| Persists despite obstacles | Gives up quickly |
| Recovers from failure | Sees failure as permanent |
| Less anxiety | High anxiety |
| Higher performance | Lower performance |
Vicarious Reinforcement vs Direct Reinforcement
| Direct Reinforcement | Vicarious Reinforcement |
|---|
| Who is reinforced? | The learner themselves | The model (learner observes) |
| Example | Student gets praised for good work | Student watches classmate get praised → works harder |
| Behaviourist concept? | Yes (Skinner) | No - requires cognition (Bandura) |
Types of Models
- Live model - Actual person demonstrating behaviour in real time (teacher, parent, peer)
- Symbolic model - Character in a book, film, TV show, social media influencer
- Verbal/Instructional model - Someone describing how to do something without demonstrating
Educational Applications of Social Learning Theory
- Teacher as role model: Teachers who show enthusiasm, curiosity, and respectful behaviour model these qualities for students.
- Peer mentoring: Pairing struggling students with high-performing peers (who are similar enough to be credible models).
- Demonstration before practice: In medical/nursing education, show the procedure before asking students to attempt it (observe → reproduce).
- Media literacy: Children learn violent or prosocial behaviour from TV, games, social media. Schools must teach critical viewing.
- Collaborative learning: Watching peers work through problems models the thinking process.
- Building self-efficacy: Design tasks to ensure early success, give specific praise, assign achievable challenges before difficult ones.
Criticisms of Social Learning Theory
- Underestimates the role of biology and genetics in behaviour
- Does not fully explain individual differences - two people watch the same model but learn different things
- The Bobo doll experiment - children may have been imitating because it was "just play" (demand characteristics)
- Overemphasis on external models - ignores spontaneous, internally-driven creativity
PART 3: EXPERIENTIAL LEARNING THEORY
Core Idea
Learning is not simply receiving information from someone else - it happens through direct personal experience combined with reflection on that experience.
Dewey's principle: "We do not learn from experience... we learn from reflecting on experience."
Kolb's definition: "Learning is the process whereby knowledge is created through the transformation of experience."
Key Theorists
1. John Dewey (1938) - Learning by Doing
Dewey rejected passive, rote classroom learning. He argued:
- Education must be rooted in real, meaningful activity
- Mere activity without reflection is not enough - experience + reflection = growth
- Learning prepares students for democratic life, not just exams
- Curriculum should connect to students' real-world interests and problems
His influence: Project-based learning, field trips, laboratories, clinical placements.
2. Kurt Lewin (1940s) - Action Research Cycle
Lewin proposed a simple cycle: Plan → Act → Observe → Reflect - essentially the forerunner of Kolb's model.
Kolb's Experiential Learning Cycle (1984) - The Core Model
David Kolb synthesised the work of Dewey, Lewin, and Piaget into a four-stage cycle. This cycle never truly ends - each time you complete it, you enter a deeper level of understanding.

Each Stage Explained with a Detailed Example
Scenario: A nursing student is learning to give an injection.
Stage 1 - Concrete Experience (CE): "I did something"
- The student gives an injection to a patient for the first time.
- This is the raw, direct, personal experience - the "doing."
- Without this actual experience, learning remains abstract and superficial.
- The experience may succeed or fail - both are valuable.
Stage 2 - Reflective Observation (RO): "I watched and thought about what happened"
- The student reflects: "What happened? What went well? What did I feel? What surprised me? What did the patient say?"
- May use a reflective journal, supervision session, or peer discussion.
- This is the stage most students skip - and that's why their learning doesn't deepen.
- Gibbs' Reflective Cycle (1988) is often used here as a structured reflective tool.
Stage 3 - Abstract Conceptualisation (AC): "I made sense of it and formed a principle"
- The student reads about injection technique, discusses with supervisor, links experience to theory: "I understand now why angle and site matter. I see how anxiety in my hands affected the outcome."
- This is where experience becomes knowledge - generalisable rules and concepts are formed.
- Without this stage, experience stays as isolated memory rather than transferable skill.
Stage 4 - Active Experimentation (AE): "I'll try it differently next time"
- The student plans: "Next time, I'll use a warmer hand to relax the muscle, and I'll explain each step to the patient first."
- Then goes back to Stage 1 with a new concrete experience - the cycle continues.
- This stage transforms learning into improved action.
Kolb's Four Learning Styles
Kolb noticed that people have preferences for how they move through the cycle - some prefer concrete experiences, others prefer theory. Based on two dimensions:
- Grasping experience: Concrete Experience (CE) vs Abstract Conceptualisation (AC)
- Transforming experience: Reflective Observation (RO) vs Active Experimentation (AE)
This creates four learning styles:
| Style | Preferred Modes | Characteristics | Best Learns By |
|---|
| Diverger | CE + RO | Imaginative, people-oriented, emotional, good at brainstorming | Observing, gathering info, group work |
| Assimilator | AC + RO | Theoretical, logical, less interested in people, good at creating models | Lectures, readings, abstract models |
| Converger | AC + AE | Practical problem-solver, technical, prefers tasks over people | Experiments, labs, technical problems |
| Accommodator | CE + AE | Hands-on, risk-taking, action-oriented, adaptable | Trial-and-error, fieldwork, projects |
Exam tip: Divergers = "feeling + watching," Assimilators = "thinking + watching," Convergers = "thinking + doing," Accommodators = "feeling + doing."
Gibbs' Reflective Cycle (1988) - Applied Version of Kolb
Graham Gibbs extended Kolb by providing a more structured 6-stage reflection model widely used in healthcare education:
1. DESCRIPTION → What happened?
2. FEELINGS → What were you thinking/feeling?
3. EVALUATION → What was good/bad about the experience?
4. ANALYSIS → What sense can you make of the situation?
5. CONCLUSION → What else could you have done?
6. ACTION PLAN → What will you do next time?
Used in nursing/medical portfolios, clinical supervision, and professional development.
Applications of Experiential Learning in Education
| Setting | Application |
|---|
| Medical/Nursing Education | Clinical placements, simulation labs, OSCE stations |
| Science Education | Laboratory experiments, fieldwork |
| Business Schools | Case studies, internships, business simulations |
| Teacher Training | Teaching practice placements with supervised reflection |
| Vocational Training | Apprenticeships, on-the-job learning |
| Military/Emergency Services | Simulation exercises, debrief sessions |
Criticisms of Experiential Learning Theory
- The four stages are oversimplified - real learning is rarely so neat and linear
- Cultural bias - Kolb's model was developed using Western, educated populations
- Learning styles concept is controversial - little solid evidence that teaching to preferred styles improves outcomes
- Neglects the role of prior knowledge and emotion
- Requires time, resources, and safe environments - not always available
PART 4: ASSOCIATIVE LEARNING THEORY
Historical Roots - From Aristotle to Modern Neuroscience
Associative learning is among the oldest and most fundamental theories of learning, tracing its roots to ancient philosophy and culminating in modern computational neuroscience.
Core Idea: The mind builds knowledge by forming associations (links) between events, stimuli, ideas, or concepts that occur together.
Aristotle's Laws of Association (4th Century BC)
Aristotle was the first to systematically describe how the mind connects ideas:
1. Law of Contiguity
- Things that occur together in time or space become associated in the mind.
- Example: If you always eat ice cream at a certain beach, thinking of that beach brings up memories of ice cream.
2. Law of Frequency
- The more often two things occur together, the stronger their association.
- Example: You associate "Paris" with the Eiffel Tower because you've seen them together thousands of times.
3. Law of Similarity
- Thinking of one thing triggers thoughts of similar things.
- Example: Hearing a song that sounds like another song reminds you of the second song.
4. Law of Contrast
- Recollecting something also triggers its complete opposite.
- Example: Thinking of the tallest person you know suddenly makes you recall the shortest one.
Philosophical Foundations - British Empiricists
John Locke: The mind at birth is a tabula rasa (blank slate). All knowledge comes from sensory experience, not innate ideas (contra Descartes).
David Hartley (1749): Associations have a physiological basis - neural vibrations pass between representations of ideas, forming the physical basis of association. Strikingly preempted the modern concept of Hebbian learning ("neurons that fire together, wire together").
David Hume: Added cause and effect (contiguity in time) as a fundamental associative law. When Event A consistently precedes Event B, we infer A causes B.
Pavlov - First Experimental Associationist
As described in Kaplan & Sadock's Comprehensive Textbook of Psychiatry:
"Pavlov was perhaps the first experimental associationist. He explored the physiologic and psychological mechanisms of association...Pavlov's work provided a framework for broad experimental exploration, some of which indicated that mere contiguity was not sufficient for learning."
The Problem with Pure Contiguity: Kamin's Blocking Effect
If associations formed simply because two events occurred together (contiguity), then all co-occurring stimuli should become associated. But Leon Kamin (1969) showed this is not so:
The Blocking Experiment:
- Phase 1: Train an animal so that a light (L) predicts a shock.
- L → Shock (animal learns to fear light)
- Phase 2: Now present light + tone (L+T) → shock together.
- Test: Present tone alone.
- Surprising result: The animal shows NO fear of the tone even though it was always paired with the shock!
Why? Because the light already perfectly predicted the shock. When the tone was added, there was no new information - no surprise - no need to learn anything new about the tone.
This means association formation is driven not by mere co-occurrence, but by surprise or prediction error - the difference between what was expected and what actually happened.
The Rescorla-Wagner Model (1972) - The Most Important Associative Learning Model
Robert Rescorla and Allan Wagner created a mathematical model that explains how the strength of an association (V) changes with each learning trial:
The Core Equation (conceptually):
ΔV = αβ(λ - ΣV)
Where:
- ΔV = Change in associative strength
- α = Salience of the conditioned stimulus (CS)
- β = Salience of the unconditioned stimulus (UCS)
- λ = Maximum associative strength possible (determined by the UCS)
- ΣV = Current total associative strength of all stimuli present
- (λ - ΣV) = PREDICTION ERROR - how surprised the organism is
What This Means Simply:
| Situation | Prediction Error | Learning |
|---|
| Outcome is completely unexpected (big surprise) | Large | Strong, fast learning |
| Outcome is somewhat expected | Moderate | Moderate learning |
| Outcome is perfectly predicted | Zero | No new learning |
| Outcome is better than expected | Positive | Increase association strength |
| Outcome is worse than expected | Negative | Decrease association strength |
How Rescorla-Wagner Explains Blocking:
- In Phase 1, light perfectly predicts shock → ΣV = λ → prediction error = 0
- In Phase 2, light + tone together: the light already accounts for all the prediction. Tone adds nothing new.
- Prediction error for the tone = 0 → No learning about the tone occurs. Blocked!
Hebbian Learning - The Neural Basis ("Fire Together, Wire Together")
Donald Hebb (1949) proposed that when two neurons repeatedly fire at the same time, the synaptic connection between them is strengthened:
"When an axon of cell A is near enough to excite cell B and repeatedly or persistently takes part in firing it, some growth process or metabolic change takes place in one or both cells such that A's efficiency, as one of the cells firing B, is increased."
Simple version: Neurons that fire together, wire together.
This provides the biological mechanism for associative learning - why pairing a bell with food eventually leads to the bell triggering the salivation reflex: the neural pathway between "bell" and "salivation" is literally strengthened.
Attention in Associative Learning
Attention is critical - it changes associability (the readiness with which a stimulus becomes associated with an outcome).
- Mackintosh's model: Stimuli that reliably predict outcomes gain attentional weight; those that don't lose it.
- Pearce-Hall model: Surprising outcomes increase attention to stimuli associated with them → facilitates new learning.
Practical implication: Novel, surprising, emotionally significant stimuli are learned faster because they attract more attention.
Prediction Error and Modern Neuroscience
The prediction error concept has been confirmed by neuroscience. Dopamine neurons in the midbrain:
- Fire in response to unexpected rewards (large prediction error)
- Show no activity when reward is fully predicted (zero prediction error)
- Show dip below baseline when an expected reward fails to appear (negative prediction error)
This is the neural currency of learning - dopamine encodes the prediction error signal that updates future expectations. It is the basis of:
- Reward learning and motivation
- Drug addiction (drugs hijack dopamine prediction error systems)
- Depression treatments (why some antidepressants target dopamine)
Applications of Associative Learning
| Area | Application |
|---|
| Phobias & PTSD | Fear is a conditioned association; exposure therapy extinguishes it by violating predictions |
| Drug Addiction | Drug cues (room, friends, paraphernalia) become CS for craving; trigger relapse |
| Marketing/Advertising | Products paired with attractive models/emotions build positive associations |
| Education | Repetition strengthens associations; novelty and surprise aid memory |
| AI/Machine Learning | Rescorla-Wagner model inspired backpropagation - the algorithm used to train neural networks |
| OCD | Compulsive rituals are negatively reinforced - they reduce anxiety via conditioned associations |
