Learning theories: classical conditioning, operant conditioning, social learning theory, and their application to explaining and treating behaviour, with key learning studies.

What this dot point is asking

Edexcel wants you to describe and evaluate classical conditioning, operant conditioning and social learning theory, apply them to real behaviour, and use the named learning studies, including Pavlov, Skinner and Bandura, plus a contemporary study. The learning approach assumes behaviour is shaped by experience, not innate, and can be studied through controlled experiments.

The answer

Classical conditioning (Pavlov)

Pavlov's dogs salivated (UCR) to food (UCS). By pairing a bell (NS) with food, the bell alone (now CS) produced salivation (CR). Key features include extinction (the CR fades if the CS is shown without the UCS), spontaneous recovery and generalisation to similar stimuli.

Operant conditioning (Skinner)

Social learning theory (Bandura)

Applications

Learning theories explain phobias (acquired by classical conditioning, maintained by operant avoidance, the two-process model) and inform treatments. Systematic desensitisation uses classical conditioning to counter-condition a relaxation response to a feared stimulus through a graded hierarchy. Token economies use operant conditioning, giving tokens (secondary reinforcers) for target behaviours.

Evaluation (GRAVE)

• Generalisability. Much evidence comes from animals (Pavlov's dogs, Skinner's rats), so simple conditioning may not fully generalise to complex human behaviour involving thought and language.
• Reliability. Controlled laboratory procedures (the Skinner box) are highly standardised and replicable, giving the approach strong scientific reliability.
• Application. The theories have produced effective, widely used treatments (systematic desensitisation, token economies) and behaviour-change techniques, a major real-world strength.
• Validity. Laboratory conditioning can lack ecological validity, and classical and operant accounts are criticised as environmentally reductionist, ignoring biology and cognition.
• Ethics. Animal studies raise welfare concerns, and behaviour modification such as token economies raises issues of control and consent in institutions.

Examples in context

Example 1. Watson and Rayner (1920) Little Albert. An 11-month-old infant, Albert, was conditioned to fear a white rat (NS) by pairing it with a loud, frightening noise (UCS, producing the UCR of fear). After several pairings the rat alone (now CS) produced crying and fear (CR). The fear also generalised to other white furry objects (a rabbit, a fur coat, a Santa mask). This is a named classic study showing that emotional responses such as phobias can be classically conditioned. Its ethics are heavily criticised (a distressed infant, no deconditioning), which makes it a useful example for evaluating both the theory and research ethics.

Example 2. Systematic desensitisation for a spider phobia. A patient with arachnophobia is taught a relaxation technique, then works up an anxiety hierarchy from least to most feared (a picture of a spider, a spider in a jar across the room, holding a jar, finally a spider on the hand). At each step the patient stays relaxed until the anxiety subsides before moving on, so the relaxation response replaces the fear response to the spider (counter-conditioning). This applies classical conditioning in reverse and is an effective, evidence-based treatment for specific phobias, showing the practical value of learning theory.

Try this

Q1. Outline the four mediational processes in social learning theory. [4 marks]

• Cue. Attention (noticing the model), retention (remembering the behaviour), reproduction (being able to perform it) and motivation (the will to imitate, driven by reinforcement).

Q2. Explain how a phobia could be acquired through classical conditioning. [3 marks]

• Cue. A neutral stimulus is paired with a frightening unconditioned stimulus, becoming a conditioned stimulus that triggers the conditioned response of fear, as in Little Albert.

Q3. Evaluate social learning theory as an explanation of behaviour. [8 marks]

• Cue. Strengths: includes cognitive mediational processes, supported by Bandura's controlled study, explains imitation and culture; weaknesses: relies on lab studies with demand characteristics, underplays biology, and shows correlation more than long-term causation.
