Chapter Notes

Overview
This chapter explores the fundamental psychological process of learning, defined as any relatively permanent change in behaviour or behavioural potential produced by experience. It covers the nature of learning, distinguishing it from temporary changes due to fatigue, drugs, or habituation, and introduces major paradigms including classical conditioning, operant/instrumental conditioning, observational learning, cognitive learning, verbal learning, and skill learning. The one big idea a student must walk away with is that learning is an inferred process involving experience, association, and relatively permanent change, and that different types of learning (from simple reflexes to complex skills) operate through distinct mechanisms and determinants.
Key Concepts (33)
Learning
Any relatively permanent change in behaviour or behavioural potential produced by experience.
e.g. A child learns to be careful with a matchbox after getting her fingers burnt from a single experience.
Habituation
A behavioural change due to continuous exposure to a stimulus, where orienting reflexes become weaker and eventually undetectable; it is not considered learning.
e.g. A person initially distracted by marriage noise nearby eventually stops noticing it after continuous exposure.
Classical Conditioning
A type of learning in which a neutral stimulus (conditioned stimulus) comes to elicit a response (conditioned response) after being paired repeatedly with an unconditioned stimulus that naturally elicits that response.
e.g. Pavlov's dog salivating to the sound of a bell after the bell was repeatedly paired with food.
Unconditioned Stimulus (US)
A stimulus that automatically and naturally elicits a response without any prior learning.
e.g. Food for a hungry dog, which naturally elicits salivation.
Unconditioned Response (UR)
The natural, automatic response elicited by an unconditioned stimulus without any prior learning.
e.g. Salivation in response to food.
Conditioned Stimulus (CS)
A previously neutral stimulus that, after repeated pairing with an unconditioned stimulus, comes to elicit a conditioned response.
e.g. The sound of a bell that, after pairing with food, elicits salivation.
Conditioned Response (CR)
A learned response elicited by a conditioned stimulus after repeated pairing with an unconditioned stimulus.
e.g. Salivation in response to the bell alone.
Operant/Instrumental Conditioning
A type of learning in which behaviour is learned, maintained, or changed through its consequences (reinforcers). The organism operates on the environment, and the response is instrumental in obtaining a reward.
e.g. A rat learning to press a lever to obtain a food pellet in a Skinner Box.
Reinforcer
Any stimulus or event that increases the probability of the occurrence of a desired response.
e.g. Food for a hungry rat, praise for a child, money for an adult.
Positive Reinforcement
Reinforcement involving stimuli that have pleasant consequences, strengthening and maintaining the responses that caused them to occur.
e.g. A child receiving a sweet for completing homework, increasing the likelihood of completing homework again.
Negative Reinforcement
Reinforcement involving unpleasant and painful stimuli; responses that lead organisms to get rid of, avoid, or escape from these stimuli provide negative reinforcement.
e.g. Putting on woollen clothes to avoid cold weather; wearing a seatbelt to avoid injury or a fine.
Punishment
A consequence that reduces or suppresses a response, unlike negative reinforcement which increases the probability of avoidance or escape.
e.g. Scolding a child for misbehaviour to reduce that behaviour.
Extinction
The disappearance of a learned response due to removal of reinforcement from the situation in which the response used to occur.
e.g. A dog stops salivating to the bell if food is no longer presented after the bell.
Generalisation
The phenomenon of responding similarly to similar stimuli after conditioning has been established.
e.g. A child conditioned to fear a person with a long moustache and black clothes also shows fear towards another person with a beard and black clothes.
Discrimination
The process of responding differently to stimuli that are different; it is complementary to generalisation.
e.g. A child shows fear to a person in black clothes but no fear to a person in grey clothes who is clean-shaven.
Spontaneous Recovery
The reappearance of a learned response after a period of time following extinction.
e.g. After a dog's conditioned salivation to a bell is extinguished, the dog may again salivate to the bell after a rest period.
Learned Helplessness
A phenomenon where an organism, after experiencing inescapable aversive events, fails to escape or avoid similar situations even when escape is possible.
e.g. Dogs subjected to inescapable electric shocks later failed to escape shocks even when they could by pressing their heads against the wall.
Observational Learning
Learning that takes place by observing others; also called social learning or modeling.
e.g. Children imitating aggressive behaviour towards a Bobo doll after watching a model being rewarded for such behaviour.
Insight Learning
A cognitive form of learning where the solution to a problem suddenly becomes clear, often after a period of no apparent progress.
e.g. Kohler's chimpanzee suddenly using a box to stand on and a pole to reach a banana out of reach.
Latent Learning
A type of cognitive learning where a new behaviour is learned but not demonstrated until reinforcement is provided for displaying it.
e.g. Tolman's rats learned the layout of a maze during unrewarded exploration but only showed efficient navigation when food was later placed at the end.
Cognitive Map
A mental representation of spatial locations and directions that an organism develops through experience.
e.g. Tolman's rats developed a cognitive map of the maze during exploration.
Verbal Learning
Learning involving words, including the acquisition of knowledge about objects, events, and their features largely in terms of words.
e.g. Learning foreign language equivalents of mother tongue words using paired-associates method.
Paired-Associates Learning
A method of verbal learning where a list of stimulus-response pairs is presented, and the learner must recall the response when given the stimulus.
e.g. Learning that 'GEN' is paired with 'LOOT', 'LUR' with 'ROOF', etc.
Serial Learning
A method of verbal learning where participants learn a list of items in a specific serial order using the serial anticipation method.
e.g. Learning a list of nonsense syllables in the exact order presented.
Free Recall
A method of verbal learning where participants are presented a list of words and later recall them in any order.
e.g. Recalling a list of 60 words from categories like names, animals, professions, and vegetables in any order.
Category Clustering
The tendency to recall words from the same semantic category together, even when presented randomly.
e.g. Bousfield's experiment where participants recalled all animal names together, all vegetable names together, etc.
Skill
The ability to perform some complex task smoothly and efficiently, consisting of a chain of perceptual motor responses or a sequence of S-R associations.
e.g. Car driving, airplane piloting, shorthand writing.
Performance Plateau
A period during skill acquisition where the level of performance stands still before transitioning to the next phase of improvement.
e.g. A learner driver who stops improving for a few sessions before suddenly becoming smoother.
Total Time Principle
A principle stating that a fixed amount of time is necessary to learn a fixed amount of material, regardless of the number of trials into which that time is divided.
e.g. Learning a list of 20 words takes the same total study time whether done in 4 sessions of 15 minutes or 2 sessions of 30 minutes.
Primary Reinforcer
A reinforcer that is biologically important and determines the organism's survival.
e.g. Food for a hungry organism.
Secondary Reinforcer
A reinforcer that has acquired its reinforcing characteristics through the organism's experience with the environment.
e.g. Money, praise, grades.
Continuous Reinforcement
A schedule where a desired response is reinforced every time it occurs.
e.g. A rat receiving a food pellet every time it presses the lever.
Partial/Intermittent Reinforcement
A schedule where responses are sometimes reinforced and sometimes not, producing greater resistance to extinction than continuous reinforcement.
e.g. A rat receiving a food pellet only after some lever presses, not all.
How It Works
Classical Conditioning Procedure (Pavlov)
  1. Phase 1: Pre-conditioning — Present food (US) to a dog, which naturally elicits salivation (UR). Present a neutral stimulus (bell) alone, which elicits no specific response (only alertness).
  2. Phase 2: Acquisition — Repeatedly pair the sound of a bell (CS) with the presentation of food (US). The bell is sounded just before the food is served.
  3. Phase 3: Test trial — Present the bell alone without food. The dog salivates (CR) to the bell, indicating conditioning has occurred.
  4. The bell becomes a signal for food, and salivation becomes a conditioned response.
💡 The conditioned response (CR) is often weaker than the unconditioned response (UR), but it is the same behaviour (salivation) elicited by a different stimulus.
Operant/Instrumental Conditioning Procedure (Skinner)
  1. A hungry rat is placed in a Skinner Box containing a lever connected to a food dispenser.
  2. The rat engages in exploratory behaviour (moving around, pawing walls).
  3. Accidentally, the rat presses the lever, and a food pellet drops onto the plate.
  4. The rat eats the food (reinforcement).
  5. Over successive trials, the rat presses the lever more quickly and frequently.
  6. Conditioning is complete when the rat presses the lever immediately upon being placed in the chamber.
💡 In operant conditioning, the response is voluntary and emitted by the organism, not elicited by a stimulus as in classical conditioning. The consequence (reinforcement) strengthens the response.
Extinction Process
  1. A learned response is established through reinforcement (e.g., lever pressing for food).
  2. Reinforcement is removed from the situation (e.g., lever pressing no longer delivers food).
  3. The learned response gradually weakens and ultimately stops occurring.
  4. The response shows resistance to extinction — it continues for some time before disappearing.
💡 Extinction does not mean unlearning; the response can reappear later through spontaneous recovery.
Spontaneous Recovery
  1. A learned response is extinguished (e.g., dog no longer salivates to bell).
  2. A period of time elapses (rest period).
  3. The conditioned stimulus (bell) is presented again.
  4. The learned response (salivation) recovers and occurs spontaneously.
  5. The longer the time lapse, the greater the recovery.
💡 Spontaneous recovery shows that extinction is not permanent; the original learning is still present in some form.
Observational Learning (Bandura's Bobo Doll Study)
  1. Children watch a film showing a model (grown-up boy) behaving aggressively towards a Bobo doll.
  2. Three versions of the film are shown to different groups: (1) model rewarded, (2) model punished, (3) no consequence.
  3. Children are then placed in a room with similar toys and allowed to play.
  4. Their behaviour is secretly observed and recorded.
  5. Children who saw the model rewarded are most aggressive; those who saw the model punished are least aggressive.
💡 Observational learning involves acquiring knowledge by observing, but performance is influenced by whether the model's behaviour was rewarded or punished.
Insight Learning (Kohler's Chimpanzee Experiment)
  1. A chimpanzee is placed in an enclosed play area with food (banana) placed out of reach.
  2. Tools such as poles and boxes are placed in the enclosure.
  3. The chimpanzee roams about for some time, showing no apparent progress.
  4. Suddenly, the chimpanzee stands on a box, grabs a pole, and strikes the banana to bring it within reach.
  5. The solution emerges suddenly and can be repeated immediately when the problem is encountered again.
💡 Insight learning is not trial-and-error; it involves a sudden cognitive restructuring of the problem, leading to a solution.
Latent Learning (Tolman's Maze Experiment)
  1. Two groups of rats are placed in a maze. Group 1 finds food at the end and learns to navigate rapidly.
  2. Group 2 is not rewarded and shows no apparent signs of learning.
  3. Later, food is placed at the end of the maze for Group 2.
  4. Group 2 rats immediately run through the maze as efficiently as Group 1.
  5. Tolman concluded that Group 2 had learned the layout (cognitive map) during exploration but did not demonstrate it until reinforcement was provided.
💡 Latent learning shows that learning can occur without immediate performance; it is not dependent on reinforcement for acquisition.
Skill Acquisition Phases (Fitts)
  1. Cognitive Phase: The learner understands and memorises instructions, and understands how the task must be performed. Every cue and response outcome is kept in consciousness.
  2. Associative Phase: Different sensory inputs are linked with appropriate responses. Errors decrease, performance improves, and time taken reduces. The learner must remain attentive.
  3. Autonomous Phase: Performance becomes automatic with minimal conscious effort. Attentional demands decrease, and interference from external factors reduces. Errorless performance is achieved.
💡 Practice is the only means of skill learning. Transitions between phases may involve a performance plateau where improvement temporarily stops.
Exam Traps — Don't Make These Mistakes
⚠ Confusing Negative Reinforcement with Punishment
✗ Negative reinforcement is punishment because both involve unpleasant stimuli.
→ Negative reinforcement increases the probability of a response (by removing an unpleasant stimulus), while punishment decreases or suppresses a response. They have opposite effects on behaviour.
✓ Negative reinforcement strengthens a response by removing an aversive stimulus (e.g., wearing a seatbelt to avoid a fine), whereas punishment weakens a response by presenting an aversive consequence (e.g., scolding a child).
⚠ Calling Habituation a Form of Learning
✗ Habituation is a type of learning because behaviour changes due to experience.
→ The chapter explicitly states that habituation is a behavioural change due to continuous exposure to stimuli, not due to learning. Learning involves relatively permanent changes from experience, while habituation is temporary and involves weakening of reflexes.
✓ Habituation is a temporary behavioural change (weakening of orienting reflexes) due to repeated exposure to a stimulus, and it is not considered learning. Learning requires relatively permanent changes from experience.
⚠ Mixing Up Classical and Operant Conditioning Terminology
✗ In operant conditioning, the US is the reinforcer, and the CS is the discriminative stimulus.
→ The terms US, UR, CS, and CR are specific to classical conditioning. In operant conditioning, the equivalent of US is the reinforcer, but there is no defined CS. The organism's response is voluntary, not elicited by a specific stimulus.
✓ In classical conditioning, we use US, UR, CS, and CR. In operant conditioning, we use operant response, reinforcer (positive or negative), and schedules of reinforcement. The reinforcer in operant conditioning is analogous to the US in classical conditioning.
⚠ Assuming Extinction Means Complete Unlearning
✗ Extinction means the learned response is completely forgotten and will never reappear.
→ Extinction involves the disappearance of a learned response due to removal of reinforcement, but the response can reappear through spontaneous recovery after a rest period. The original learning is not erased.
✓ Extinction is the gradual weakening and disappearance of a learned response when reinforcement is removed. However, the response can recover spontaneously after a time lapse, showing that the learning is not completely lost.
⚠ Thinking Observational Learning Requires Direct Reinforcement
✗ Observational learning only occurs if the observer is directly rewarded for imitating the model.
→ Bandura's study showed that children learned aggressive behaviour by observing a model, regardless of whether the model was rewarded or punished. Performance (acting out the behaviour) was influenced by the model's consequences, but learning (acquiring knowledge) occurred in all conditions.
✓ In observational learning, observers acquire knowledge by observing the model's behaviour. Performance of the learned behaviour is influenced by whether the model was rewarded or punished, but learning itself does not require direct reinforcement.
⚠ Confusing Insight Learning with Trial-and-Error
✗ Insight learning is the same as trial-and-error learning because both involve trying different solutions.
→ Insight learning involves a sudden, clear solution after a period of no apparent progress, not gradual trial-and-error. Kohler's chimpanzees did not randomly try actions; they suddenly reorganised their perception of the problem.
✓ Insight learning is a cognitive process where the solution to a problem suddenly becomes clear after a period of contemplation. It is distinct from trial-and-error learning, which involves gradual elimination of incorrect responses through reinforcement.
Compare & Contrast
Nature of response
Classical Conditioning
Operant/Instrumental Conditioning
In classical conditioning, responses are reflexes automatically elicited by stimuli (respondent behaviour). In operant conditioning, responses are voluntary, emitted by the organism (operant behaviour), and under its control.
Role of the organism
Classical Conditioning
Operant/Instrumental Conditioning
In classical conditioning, the organism remains passive; the experimenter controls the occurrence of the US. In operant conditioning, the organism must be active to produce the response and obtain reinforcement.
Effect on behaviour
Negative Reinforcement
Punishment
Negative reinforcement increases the probability of a response by removing an aversive stimulus (e.g., escaping cold by wearing warm clothes). Punishment decreases or suppresses a response by presenting an aversive consequence (e.g., scolding a child).
Response to stimuli
Generalisation
Discrimination
Generalisation is responding similarly to similar stimuli (e.g., fearing all men in black clothes). Discrimination is responding differently to different stimuli (e.g., fearing only the man with a long moustache, not a clean-shaven man).
Role of reinforcement in performance
Insight Learning
Latent Learning
In insight learning, the solution emerges suddenly and is immediately performed without needing external reinforcement. In latent learning, the behaviour is learned but not demonstrated until reinforcement is provided for displaying it.

MCQs — 10 Questions with Answers

Q1. Ivan Pavlov discovered classical conditioning while studying which physiological process?

  • A. Digestion in dogs ✓
  • B. Memory formation in rats
  • C. Brain wave patterns in cats
  • D. Reflex arc in humans

Answer: A — Pavlov was investigating digestion physiology when he noticed dogs salivating at sight of empty food plates, leading to his classical conditioning discoveries.

Q2. If a student feels anxious whenever she enters the examination hall, and this anxiety did not exist before her first difficult exam experience, this is an example of which learning paradigm?

  • A. Operant conditioning through punishment
  • B. Classical conditioning through association ✓
  • C. Observational learning through modelling
  • D. Latent learning through cognitive maps

Answer: B — The examination hall (CS) became paired with the difficult exam experience (US), producing anxiety (CR), which is the core mechanism of classical conditioning.

Q3. Which of the following is NOT a characteristic of learning as defined in psychology?

  • A. It produces relatively permanent changes in behaviour
  • B. It results from direct experience
  • C. It includes temporary changes due to fatigue or drugs ✓
  • D. It involves psychological processing of information

Answer: C — Temporary changes from fatigue, habituation, or drugs are explicitly excluded from learning; learning must be relatively permanent and experience-based.

Q4. A factory worker receives Rs 500 for every 100 units produced. According to operant conditioning, this is an example of which reinforcement schedule?

  • A. Fixed interval reinforcement
  • B. Variable ratio reinforcement
  • C. Fixed ratio reinforcement ✓
  • D. Variable interval reinforcement

Answer: C — Fixed ratio schedule provides reinforcement after a fixed number of responses (every 100 units = fixed ratio); the predictability and unit count define it as fixed ratio, not variable.

Q5. In Bandura's Bobo doll experiment, children imitated aggressive behaviour of adults. This demonstrates that learning can occur: Assertion: Through observational learning without direct reinforcement of the learner. Reason: The children received direct rewards for imitating the aggressive behaviour.

  • A. Both assertion and reason are correct; reason explains assertion
  • B. Both assertion and reason are correct; reason does not explain assertion
  • C. Assertion is correct; reason is incorrect ✓
  • D. Assertion is incorrect; reason is correct

Answer: C — The assertion is correct—children learned without direct reinforcement by observing and imitating. The reason is incorrect because children did not receive direct rewards for their imitation, which was the key point demonstrating learning without reinforcement.

Q6. A dog trained to sit on command (CS) when shown a hand gesture will also sit when shown a similar hand gesture by a different person. This phenomenon is called:

  • A. Discrimination in classical conditioning
  • B. Spontaneous recovery
  • C. Generalisation in classical conditioning ✓
  • D. Extinction of the conditioned response

Answer: C — Generalisation occurs when the conditioned response transfers to stimuli similar to the original CS (hand gesture by different person); discrimination would be the opposite—responding only to the exact CS.

Q7. Edward Thorndike's 'Law of Effect' states that: Assertion: Behaviour followed by satisfying consequences is more likely to be repeated. Reason: The organism consciously decides which behaviour will lead to rewards.

  • A. Both assertion and reason are correct; reason explains assertion
  • B. Assertion is correct; reason is incorrect ✓
  • C. Both are incorrect
  • D. Reason is correct; assertion is incorrect

Answer: B — The assertion correctly states Thorndike's Law of Effect—satisfying consequences strengthen behaviour. However, the law does not require conscious decision-making; it operates through automatic association, making the reason incorrect.

Q8. Tolman's latent learning experiments with rats in mazes demonstrated that: Assertion: Rats developed cognitive maps of the maze without visible learning performance. Reason: Rats were given food rewards before being allowed to explore the maze.

  • A. Both assertion and reason are correct; reason explains assertion
  • B. Assertion is correct; reason is incorrect ✓
  • C. Both are incorrect
  • D. Reason explains why latent learning occurs

Answer: B — The assertion is correct—rats learned the maze layout (cognitive maps) without visible performance, which was revealed only when motivated by rewards. The reason is backward; motivation (food rewards) revealed already-existing learning, not caused the initial learning without performance.

Q9. A student studied biology using active recall and spaced repetition for her Class 10 board exam and finds that the same studying method helps her learn chemistry in Class 11. This is an example of which type of transfer of learning?

  • A. Negative transfer because different subjects are involved
  • B. Zero transfer because chemistry requires different skills than biology
  • C. Positive transfer because prior study skills help new subject learning ✓
  • D. No learning has occurred, only performance improvement

Answer: C — Positive transfer occurs when prior learning (study methods from biology) facilitates learning of new material (chemistry); the common underlying skill (effective study technique) transfers across subjects.

Q10. Compare classical conditioning and operant conditioning: (i) Classical conditioning involves substituting a neutral stimulus for a naturally occurring stimulus. (ii) Operant conditioning involves consequences of behaviour shaping future behaviour. (iii) Both require the learner to be actively responding to stimuli. (iv) Classical conditioning is more useful for training complex skills like driving.

  • A. Only (i) and (ii) are correct ✓
  • B. Only (ii) and (iii) are correct
  • C. Only (i), (ii), and (iii) are correct
  • D. (i), (ii), (iii), and (iv) are all correct

Answer: A — (i) Correct—CS substitutes for US. (ii) Correct—consequences reinforce/punish behaviour. (iii) Incorrect—classical conditioning is automatic/passive; learner need not actively respond. (iv) Incorrect—operant conditioning (reinforcement) is better for complex skill training than classical conditioning.

Flashcards

Define learning in psychology

Learning is any relatively permanent change in behaviour or behavioural potential produced by experience.

Who conducted the classical conditioning experiments and with which animal?

Ivan P. Pavlov conducted classical conditioning experiments with dogs.

What is the difference between the unconditioned stimulus (US) and conditioned stimulus (CS)?

The unconditioned stimulus naturally produces a reflex response without prior training, while the conditioned stimulus produces the same response only after being paired with the unconditioned stimulus.

What is extinction in classical conditioning?

Extinction occurs when the conditioned response gradually disappears after the conditioned stimulus is presented repeatedly without the unconditioned stimulus.

Define operant conditioning and name its key originator

Operant conditioning is learning through consequences of behaviour, where reinforcement increases and punishment decreases behaviour frequency, primarily studied by B.F. Skinner.

What is positive reinforcement versus negative reinforcement?

Positive reinforcement adds a desirable consequence to increase behaviour, while negative reinforcement removes an unpleasant consequence to increase behaviour.

What is the Bobo doll experiment and who conducted it?

Albert Bandura's Bobo doll experiment showed that children imitate aggressive behaviour modelled by adults, demonstrating observational learning without direct reinforcement.

What is latent learning according to Tolman?

Latent learning is learning that occurs without observable performance and is revealed only when motivation or reward is introduced, involving internal cognitive maps.

What is the difference between insight learning and trial-and-error learning?

Insight learning involves sudden restructuring of the problem (e.g. Sultan the chimpanzee reaching the banana), while trial-and-error involves gradual learning through repeated attempts.

What does transfer of learning mean with an example?

Transfer of learning is the application of skills learned in one context to another context, such as positive transfer when learning to drive a car helps learning to drive a motorcycle.

Important Board Questions

Define learning and distinguish it from temporary behavioural changes caused by fatigue and habituation. Give one example of each. [2 marks]

State learning as 'relatively permanent change from experience'; explain fatigue and habituation are temporary and reversible; provide one real example for each (e.g. learning to ride a bike vs temporary tiredness while studying).

Explain classical conditioning with reference to Pavlov's experiments. Describe the processes of acquisition, extinction, and spontaneous recovery with one example. [5 marks]

Define classical conditioning as stimulus substitution; explain US-UR and CS-CR pairing in Pavlov's dog experiment; define and exemplify acquisition (repeated pairing strengthens CR), extinction (CS without US weakens CR), and spontaneous recovery (CR reappears after rest); use one consistent example throughout (e.g. dog salivating to bell).

Analyse how operant conditioning differs from classical conditioning in terms of stimulus presentation, role of learner, and practical applications. Use a relevant Indian classroom or workplace example to illustrate the superiority of operant conditioning for teaching complex skills. [6 marks]

Compare: classical uses automatic responses and stimulus substitution, operant uses consequences and active responding; explain learner is passive in classical but active in operant; discuss reinforcement vs punishment mechanics; apply operant conditioning principles to a concrete Indian example (e.g. teacher giving praise/marks for good answers, worker receiving bonus for productivity) to show how positive reinforcement develops complex skills better than classical conditioning's passive association.

Assertion-Reason Questions for Learning

Q1. Assertion (A):

Learning is defined as any relatively permanent change in behaviour or behavioural potential produced by experience, and must be distinguished from temporary behavioural changes due to fatigue or drugs.

Reason (R):

Temporary changes like those caused by sedatives or exhaustion lack the permanence and experience-based nature that are essential features of learning.

Answer: A — Both A and R are true, and R is the correct explanation of A — Both the assertion and reason are true, and the reason correctly explains why temporary changes (fatigue, drugs) are excluded from the definition of learning. The permanence and experience-basis are indeed the distinguishing criteria.

Q2. Assertion (A):

In Pavlov's classical conditioning experiments, the bell (initially a neutral stimulus) eventually produces salivation in dogs because it becomes a conditioned stimulus.

Reason (R):

The bell produces salivation because it naturally triggers a reflexive response in the dog's digestive system, independent of prior conditioning.

Answer: C — A is true but R is false — The assertion is true—the bell becomes a conditioned stimulus through repeated pairing with food. However, the reason is false; the bell does NOT naturally trigger salivation. The salivation occurs specifically because of conditioning, not due to an innate reflex. This tests understanding of how conditioned responses differ from unconditioned reflexes.

Q3. Assertion (A):

Habituation—such as the gradual weakening of response to wedding noise—is not considered learning because the behavioural change is temporary.

Reason (R):

Habituation produces permanent changes in behaviour and is therefore a form of learning similar to classical conditioning.

Answer: C — A is true but R is false — Both statements are false. While habituation does occur due to continuous exposure, the assertion incorrectly states it is temporary; however, habituation-based adaptations can be relatively lasting. More critically, the reason is false because habituation is NOT the same as learning—the chapter explicitly states that habituation does not qualify as learning despite sometimes producing relatively stable changes.

Case-Based Questions (CBQ) for Learning

Case Study:

Rajesh, a 10-year-old student, attended his first day at a new school. During the assembly, the principal rang a large bell, which was then followed by all students sitting quietly and respectfully. After two weeks, Rajesh noticed that whenever he heard this specific bell sound, he automatically sat quietly and showed respect, even if the principal was not present. Over the next month, the same bell was used to signal lunch time, and within a few days, Rajesh began to feel hungry whenever he heard the bell, even if lunch was actually several hours away. However, after the school changed its lunch time policy, the bell continued to ring at the old time, but food was not served. Within three weeks, Rajesh no longer felt hungry at the bell sound.

Q1. In the above scenario, what type of learning is demonstrated when Rajesh automatically sits quietly upon hearing the bell?

  • A. Classical conditioning, as the bell becomes a conditioned stimulus paired with sitting quietly ✓
  • B. Operant conditioning, as sitting quietly is reinforced by the principal's approval
  • C. Observational learning, as Rajesh observes other students sitting quietly
  • D. Cognitive learning, as Rajesh consciously decides to sit quietly

Answer: A

Q2. When Rajesh feels hungry at the bell sound even though the principal is not present, this demonstrates:

  • A. Spontaneous recovery of hunger responses
  • B. Stimulus generalisation to other bell sounds
  • C. A conditioned response to the conditioned stimulus (bell) ✓
  • D. Habituation to the lunch routine

Answer: C

Q3. After the lunch time policy changed and the bell no longer predicted food availability, Rajesh stopped feeling hungry at the bell within three weeks. This process is called:

  • A. Stimulus discrimination between old and new bell sounds
  • B. Extinction of the conditioned response ✓
  • C. Spontaneous recovery of the original hunger reflex
  • D. Retroactive interference from the new lunch schedule

Answer: B

Q4. Based on the learning principles illustrated in Rajesh's experience, which statement is correct?

  • A. Learning requires conscious effort and intention from the learner
  • B. Once a response is conditioned, it remains permanent regardless of changed circumstances
  • C. Repeated association between a stimulus and outcome creates learning, but this association weakens when the pairing stops ✓
  • D. Classical conditioning can only produce behavioural responses, not physiological ones like hunger

Answer: C
