Evaluation of the Behaviourist Approach

State one strength.

Strength: Scientific

Explain what is scientific.

Explain:

By focusing only on observable behaviour that can be measured and recorded, the approach moves away from subjective interpretation and toward objective data

Give evidence for scientific.

Evidence:

Behaviourists use laboratory experiments to form hypotheses and test them under controlled conditions, ensuring the quality of the evidence is high and replicable

Why is scientific a strength?

Why:

Strength because…

• This scientific status makes the approach more credible and likely to receive funding

• It ensures that the treatments derived from the approach are seen as legitimate by the medical and scientific communities

State one weakness.

Weakness: Reductionist

Explain what is reductionist.

Explain:

• A reductionist view helps identify simple causal factors

• By ignoring complex cognitive or biological noise, researchers can isolate exactly which rewards or punishments are driving a specific action

Give evidence for reductionist.

Evidence:

Aversion Therapy:

• Reduces the complex issue of addiction down to faulty learned association

• By pairing an addictive substance with an unpleasant stimulus, the behaviour is modified through simple counter-conditioning

Why is reductionist a weakness?

Why:

Weakness because this makes behaviour easier to modify, it risks losing a real understanding of human complexity

State a second strength.

Strength: Applications

Explain what is applications.

Explain:

The principles of reinforcement are easy to implement and observe, they can be used to improve behaviour and encourage functional habits in large groups of people

Give evidence for applications.

Evidence:

These principles are used successfully in education (star charts/rewards), the home, and healthcare settings (token economies in psychiatric wards)

Why is applications a strength?

Why:

Strength because…

• The wide use of these principles in the real world supports the validity of the approach

• It shows that behaviourist theories are not just theoretical but are effective tools for benefiting society

State a second weakness.

Weakness: Nature vs Nurture

Explain what is nature vs nurture.

Explain:

This ‘blank slate’ view allows researchers to conduct focused research with clear parameters, as they do not have to account for the internal ‘black box’ of genetics or biology

Give evidence for nature vs nurture.

Evidence:

Raine et al. found that genes and brain structure (like reduced activity in the pre-frontal cortex) play a significant role in aggression, which behaviourism cannot explain

Why is nature vs nurture a weakness?

Why:
Weakness because…

• The approach provides an incomplete explanation

• Behaviourism fails to account for biological predispositions that influence how we react to our environment
