Habituation, extinction, learned helplessness and modelling
- Concept
Besides conditioning, people learn by getting used to things, by unlearning, by giving up when nothing they do matters, and by watching others.
What it is
Several learning phenomena are asked together. Habituation is the simplest, non-associative form: the response to a repeated, harmless stimulus fades. Extinction weakens a conditioned response when its link is broken. Learned helplessness is the passivity that follows repeated uncontrollable bad events. Modelling (observational learning, Bandura) is learning by watching what others do and what happens to them.
Learning phenomena side by side
| Phenomenon | Type of learning | Original example | Why it matters in medicine |
|---|---|---|---|
| Habituation | Non-associative | A nurse stops hearing the hum of the ventilators after a week on the unit | Alarm fatigue; also the basis for staying in a feared situation until anxiety falls |
| Sensitization | Non-associative | After a car crash, a man jumps at every horn | Hyperarousal after trauma; central sensitization in chronic pain |
| Extinction | Classical or operant | A child's fear of the dentist fades after several painless visits | Basis of exposure therapy; relapse risk through spontaneous recovery |
| Learned helplessness | Learning that outcomes are uncontrollable | After three failed attempts at diets, a woman stops attending nutrition visits | Model of depression; low perceived control worsens adherence |
| Modelling | Observational (social learning) | A teenager starts vaping after seeing an older cousin do it | Health behaviors spread through models; peer-led programs and patient testimonies use it |
Clinical notes
- Learned helplessness was reversed in animals by forcibly showing them that escape worked, and prevented by prior experience of control: the logic behind graded tasks and behavioral activation.
- Clinicians model behavior too: patients copy how the team handles hand hygiene, inhaler technique or calm communication.
- Extinction of drug-seeking in the clinic does not remove cue reactivity in the patient's neighbourhood (renewal), one reason for relapse after discharge.
Test yourself
Think of the answer, then tap the question to see it.
What did Seligman's dogs do after receiving shocks they could not escape?
When later placed where escape was possible, they did not try to escape: they had learned that their actions did not change the outcome (learned helplessness).
What attributional style is linked to learned helplessness and depression in the reformulated model?
Explaining bad events as caused by oneself (internal), lasting (stable) and affecting everything (global).
What are the four steps of observational learning according to Bandura?
Attention to the model, retention in memory, reproduction of the behavior, and motivation to perform it, which depends largely on what happened to the model.
How does habituation differ from extinction?
Habituation is non-associative: the response to a repeated harmless stimulus fades. Extinction weakens a learned association when the CS no longer predicts the UCS or the behavior is no longer reinforced.
