the biological approach
assumptions
-
to understand human behaviour, we must look to biological structures and processes within the body
if we understand the brain and its function, we can explain our thoughts and behaviour
contributions
theory
-
provides us with theories on the innate principles that determine our behaviour provide strong arguments for nature
methodology
-
animal studies used to assess the physiological structures that influence behaviour and to support evolutionary explanations
-
objective methods such as measuring neurotransmitters in blood are used and approach considered scientific
application
-
based on genetics individuals who may be vulnerable to certain conditions such as sz can be identified early and supported
-
-
evolution and behaviour
-
natural selection
any genetically determined behaviour that enhances an individuals survival (and reproduction) will continue in future generations
-
possessor more likely to survive, reproduce and pass on traits
adaptive advantage
more likely to adapt to our environment, and therefore more likely to survive and pass on genes
-
evaluation
limitation- concordance rates never fully explain behaviour, as never 100%. interactionist approach much more comprehensive explanation of behaviour as combines biological approach and environmental factors (diathesis stress model). means should look to combine approaches incorporating both nature and nurture to have more comprehensive understanding of human behaviour
strength- to investigate genetic and biological basis of behaviour, uses range of precise and highly scientific methods. include scanning techniques such as FMRI and twin studies and drug trials. means based on reliable data and has a credible scientific basis
