The Behaviourist Approach

The behaviourist approach is a perspective in psychology that focuses on observable behaviour rather than internal mental processes like thoughts or emotions.

Core idea:

Behaviourists argue that behaviour is learned through interaction with the enviroment, mainly via conditioning.

Classical conditioning

Developed by Ivan Pavlov.

Learning happens through association between stimuli.

A neutral stimulus (like a bell) is repeatedly paired with an unconditioned stimulus (like food), which naturally produces a response (salivation).

Over time, the neutral stimulus becomes a conditioned stimulus, producing the response on its own.

This type of learning is passive, meaning the learner does not actively choose to behave - it happens automatically.

Although classical conditioning mainly focuses on automatic responses, it helps explain how emotional reactions (like fear or anxiety) can be learned through association.

Operant conditioning

Developed by B. F. Skinner.

Learning occurs through the consequences of behaviour.

Behaviours followed by reinforcement are more likely to be repeated, while those followed by punishment are less likely.

Types of Reinforcement:

Positive reinforcement: adding a reward to increase a behaviour (e.g. giving praise or treats after a desired action)

Negative reinforcement: removing something unpleasant to increase a behaviour (e.g. stopping a loud noise when a correct response is made)

Reinforcement strengthens behavior, making it more likely to happen again.

This process is more active than classical conditioning, as the individual operates on the enviroment and learns from the outcomes of their actions.

Skinner used experiments (like the ‘Skinner box’) to show how behaviour can be shaped step-by-step through reinforcement.

Enviromental determinism

Behaviourists believe behaviour is largely determined by external enviromental factors, not free will

Focus on observable behaviour

Only behaviours that can be seen and measured are studied scientifically

Key Assumptions:

  • Humans and animals learn in similar ways

  • All behaviour is learned from the enviroment

  • Psychology should be objective and scientific

Evaluation (A03 Points):

Strengths:

  • Highly scientific and testable (controlled experiments)

  • Practical applications (e.g. behaviour therapy, education, parenting strategies)

  • Clear cause-and-effect relationships

Limitations:

  • Ignores internal processes like thoughts and emotions

  • Can be seen as overly deterministic

  • Doesn’t fully explain complex human behaviour (e.g. creativity, language)
