Strengths Of The Biological Approach

The biological approach attempts to explain all behaviour through biology, particularly focusing on genetics, neurochemistry and hormonal changes as well as how evolution may have shaped human behaviour. Genes carry the instructions for the development of characteristics like intelligence, temperament and height. The main focus on how genetics has influenced our behaviour has looked at genotype and phenotype. Genotype is the genes a person has. Phenotype is the characteristics their genes produce. The genetic basis of behaviour has focused on trying to identify how much behaviour is influenced by genes and how much is influenced by the environment. Identical and non-identical twins have been used in research to clarify heritability and variation
This will either increase or decrease their likelihood of survival. Psychologists believe many psychological characteristics like aggression can be explained through evolution. Aggression may have served the purpose of increasing survival and protecting territory. The biological approach uses the scientific method like the experimental method as its main form of investigation which gives this approach validity. Studies using this approach take place in highly controlled lab settings which are reliable as they make replication of the same experimental conditions for the verification of results possible. The results gained are also more objective as they are based on biology compared to subjective reporting or observations which also give the biological approach more validity. Another strength of the biological approach is that it can make clearer predictions regarding behaviour and possible links it has to biology. For example, predicting the effects of neurotransmitters on behaviour become easier when looking at those who are genetically related. This has contributed to the development of drug treatments and real world
