The Bell That Learned to Frighten
Rohan, 14, is in Class IX at a suburban Mumbai school. Every Friday his mathematics teacher, Mrs. Deshmukh, rings a small brass bell to start a 20-minute timed test. The tests are hard, and Mrs. Deshmukh often announces marks aloud and scolds students who score below 40%. After four weeks, Rohan's palms sweat and his heart races when the bell rings. By the sixth week he feels uneasy during the school assembly when the same bell is rung, although no test follows. He now avoids the mathematics room, copies homework, and says, 'I blank out.' His parents call him lazy and stop his Sunday cricket when his marks fall. The counsellor notes he sleeps about five hours, eats little before tests, and has stopped asking questions in class. The maths teacher wants a quick fix before the practical examinations and proposes that Rohan be kept after school whenever he avoids maths.
1. Using classical conditioning, identify the unconditioned stimulus, unconditioned response, conditioned stimulus and conditioned response in this case. Explain why the assembly bell now produces unease.
Read the worked answer
Before conditioning
- The brass bell is a neutral stimulus: at first it produces no anxiety.
- The hard test and public scolding are the unconditioned stimulus (UCS) because they naturally trigger distress.
- Rohan's racing heart and sweating are the unconditioned response (UCR).
During conditioning The bell is rung repeatedly just before the aversive test and scolding. The bell becomes a predictor of a unpleasant event.
After conditioning
- The bell alone becomes the conditioned stimulus (CS).
- Anxiety in response to the bell is the conditioned response (CR).
The response to the assembly bell illustrates stimulus generalisation: the assembly bell is similar in sound and context to the maths bell, so Rohan responds to it as if a test were coming. This is not 'weakness' or 'laziness'; it is a learned anticipatory fear. The fact that the response appears in a new setting shows that the learning has spread beyond the original room. A good answer should also note that the anxiety is now partly self-maintaining: Rohan avoids maths, which reduces his anxiety briefly, but prevents him from learning that the bell no longer always predicts failure.
2. The teacher proposes after-school detention whenever Rohan avoids maths. Evaluate this plan from an operant conditioning perspective and propose a more defensible conditioning-based plan.
Read the worked answer
Evaluation of detention Detention is a positive punishment: an aversive consequence is added after avoidance. Punishment may suppress behaviour while the teacher is watching, but it does not teach a new response. In Rohan's case, avoidance is already being negatively reinforced because leaving or avoiding maths removes the conditioned anxiety. Adding punishment can strengthen escape behaviour, increase lying or copying, and make the maths room even more aversive. It also does not address the conditioned bell-anxiety.
Better conditioning-based plan
- Extinction: present the bell repeatedly without a hard test or public scolding, so the CS no longer predicts the UCS.
- Graded exposure: begin with a short, easy bell-signalled task in a safe room, then gradually increase difficulty.
- Relaxation training: teach Rohan to breathe slowly while the bell is present, so a calm response can compete with anxiety.
- Positive reinforcement: praise or reward small approach behaviours, such as entering the maths room or attempting one question.
- Shaping: reinforce successive steps rather than waiting for full attendance.
- Remove humiliation: return marks privately and avoid public scolding.
The plan should expect an extinction burst-a temporary increase in avoidance when the old pattern stops working-and should be applied consistently. The aim is to build a new learned association, not merely to punish the old one.
3. Rohan's parents say he is 'lazy.' Explain why this is not a sufficient psychological explanation, using at least two learning concepts.
Read the worked answer
Calling Rohan 'lazy' is a trait label, not an explanation. It describes the behaviour but does not identify its antecedents or consequences, so it can stop adults from looking for causes and can make Rohan feel blamed.
Two learning concepts explain the behaviour better:
- Classical conditioning: the bell has become a CS for anxiety. Rohan's avoidance is a reasonable response to a learned danger signal, not a moral failure. His sleep loss and poor eating may also increase irritability and reduce concentration.
- Operant conditioning: avoidance is negatively reinforced because it removes anxiety in the short term. Copying homework may also be reinforced by avoiding failure or scolding. At the same time, parental removal of cricket is punishment that may increase conflict without teaching maths skills.
A third relevant process is observational learning: if Rohan sees adults respond to difficulty with blame or avoidance, he may model that pattern. The better explanation is a combination of conditioned anxiety, reinforcement of avoidance, and stressful testing conditions. The practical implication is to assess the antecedents (bell, public marks), the behaviour (avoidance), and the consequences (anxiety relief, scolding), then change the environment and teach approach behaviour.
