Biological Approach: Strengths and Weaknesses
There are several different approaches to the study of psychology: psychodynamic, cognitive, biological, and learning.

Strength - good testability
- The biological approach follows the scientific method.
- This allows for reliable and valid data on which statistical tests can be performed.
- This means it has good testability.

Strength - treatments
- Similar to the cognitive approach, the biological approach allows for the development of biological treatments.
- For example, depression is caused by an unbalance in neurotransmitters, and then treatments can be tailored accordingly.
- This makes the approach useful and applicable.

Weakness - lack of insight into environment
- As the focus of the approach is on the internal biology of a person, there is a lack of insight into environmental factors such as family life, social status, and their childhood.

Weakness - responsibility issue
- Some think that if there is a biological explanation for behaviour, for example aggression linked to criminal acts, it can allow people the excuse not to take responsibility for their behaviour.
