Genetics and Behaviour
Behavioural Genetics- the study of how both genetics and the environment contribute to individual variations in human behaviour.
Humans share 93% of our DNA with the Rhesus Monkey. However no single gene is responsible for complex behaviours such as intelligence, criminal behaviour etc. DNA simply provides the building blocks for these behaviours. The environment can play a vital role also. Psychologists argue that although some people may have a genetic ´predisposition´ towards a behaviour, the appropriate environmental stimuli is required for the behaviour to manifest itself. |
Genetic research relies predominantly on the results of ´correlational studies´ such as the Minnesota Twins study. Lets review this type of research as well as experimental methods.
1) How do correlational studies differ to from both Naturalistic Observation and Experimental methods?
2) Which type of study is more reliable and valid in your opinion? Why?
3) Why are correlational studies more often used when researching behavioural genetics.

- With reference to relevant research studies, to what extent does genetic inheritance influence behaviour?
- Examine one evolutionary explanation of behaviour.
- Discuss ethical considerations in research into genetic influences on behaviour.
