Biological approach

Question 1

name 2 assumptions of the biological approach

Answer 1

1. behaviour is a product of evolution
2. behaviour is influenced by the central nervous system, genes and neurochemistry

Question 2

name 2 overall strengths of the biological approach

Answer 2

1. it is a scientific approach because it uses controlled experiments to investigate behaviour. it focuses on investigating brain structures, biochemistry and genes.
2. the approach has practical application so is useful. eg, the development of drugs to help chemical imbalances in the brain.

Question 3

name 1 overall limitation of the biological approach

Answer 3

1. it is an incomplete explanation because it focuses only on how biological factors influence behaviour. it does not consider the influence of other factors like the environment and stimulus response associations (cc), reinforcement, punishment (oc) and the role of models (slt)
