Behaviourist

All behaviour is learned and shaped by the enviroment

Usefulness -> skinners experiment about oparate conditioning is useful as it was very scientific, it offers a very practical way in changing behaviour.

However it does raise ethical issues as it is argued whether behaviour should be controlled. It only gives a partial explanation of human experience as it ignores cognitive processes making it reductionist. The practical uses tend to be short lived, they do change behaviour, but only for a limitted time, they also often use animals with is seen as an ethical issue.

Biological approach

the biological approach aims to explain all behaviour as a product of biological proccesses and factors such as hormones and neurone responce in the brain.

Strengths,

Everyone has a brain so it applies to everyone, suchs as sperys study of the effects of a commissurcetomy so the same effects would apply to all people. use of precise equipment and technology means that we will have a accurate results from testing.

Weaknesses.

Cost, studies in the biological approach can be expensive as high quality equipment is needed, E.g dement and kleimans study on dreams the equipment was expensive to monitor dreams and sleep. low ecological validity

Psychodynamic

Strengths: Freuds belife in determaninism + his detailed collection of data provided scientific support for his theory. Thigpen and cleckly, much more in depth analysis of eves behaviour

Weakness: freud used unrepresentable samples + techniques that were not trully objective - seen to bias ( lack of scientific support) 

* considers that human behaviour is result of unconscious processes.
