The Biological Approach

Question 1

Assumptions

Answer 1

• Everything psychological is at first biological
  An understanding of brain structure and function can explain our thoughts and behaviour
• The mind lives in the brain–> all thoughts, feelings and behaviour have a physical basis

Question 2

Genetic Basis of Behaviour

Answer 2

Study whether behavioural characteristics are inherited the same way as physical characteristics
Twin studies are used to determine the likelihood that certain traits have a genetic basis by comparing concordance rates

Question 3

Genotype and Phenotype

Answer 3

Genotype- actual genetic make up
Phenotype- way that genes are expressed through physical, behavioural and psychological characteristics

Question 4

Evolution and Behaviour

Answer 4

The changes in inherited characteristics in a biological population over successive generations
Proposed by Charles Darwin
Theory of Natural Selection

Question 5

AO3- Biological Approach
Scientific Method

Answer 5

Makes use of precise and highly scientific methods
i.e scanning techniques (fMRI, EEG), twin studies, drug trials
It’s possible to accurately measure biological and neural processes in ways that aren’t open to bias

Question 6

AO3- Biological Approach
Real World Application

Answer 6

Led to the development of psychoactive drugs that treat serious mental disorders such as depression
They have revolutionised treatment for many
People with mental disorders are able to manage their condition and live a relatively normal life rather than remain in hospital

Question 7

AO3- Biological Approach
Deterministic

Answer 7

It sees human behaviour as governed by internal, biological causes over which we have no control
Implications for the legal system and wider society
The discovery of the criminal gene may complicate what is viewed as morally right or wrong
