The Biological approach
- The Biological approach uses scientific methods when conducting research and experiments.
- It gives strong strong arguments for the nature side of the nature-nurture debate
- The biological approach has heped society in many ways , for example drugs that help with disorders such as bipolar and depression.
- The biological approach is reductionist. it only explains all thoughts nd behaviour by terms of nerves or chemicals
- The approach is too simplistic, it fails to consider other factors such as environmental factors and how they can also have an influence on behaviour.
- The approach raises ethical issues. For example genetic mapping. There could be negative consequences from artificially manupilating our genetic make-up.
- The biological approaches stresses the importance of nature in the nature -nurture debate
- The principles of biology are applied to psychology so we understand behaviours such as imprinting.
- biology enables psychologists to manipulate a species genetic make-up in order to investigate the genetic basis of behaviour.
- Darwins theory of evolution shows how our strongest genes stay with us through generations to help us survive, whilst the maladaptive genes die out.
- This approach allows us to observe many examples of evolutionary behaviour in different species, for example sexual selection, and in humans - the rooting reflex.
