The biological approach uses the scientific method as its main method of investigation, which are objective and reliable.
Experiments take place in highly controlled environments so that other researchers can replicate the research, increasing the internalvalidity.
There are significant applications of biological research in the real world such as drugtherapy.
Understanding the biology of an individual can help predict their future behaviour.
Studying the brain is useful, so comparisons can be made to help brain-damaged individuals.
Scanningtechniques are used to study the brain which are very objective.
The biological approach uses scientific methods to explain behaviour.
Having an understanding of neurotransmitters means drugs such as SSRIs for depression can be used successfully.
The biological approach is very reductionist as it aims to find one underlying cause for behaviour.
The biological approach is very deterministic as it assumes behaviour is pre-determined by biologicalprocesses.
Reductionism is the belief that complex human behaviour can be explained by breaking it down into its smallest parts, such as the action of genes, neurochemicals and hormones.
We cannot fully understand a behaviour without taking account of the other factors that influence it, such as cognitive, emotional and cultural factors.
