The Biological Approach Flashcards
What is Biological Psychology?
Tries to explain human behaviour in terms of biology
What is the biological approach?
- Combination of psychology and biology (= physiological) to explain behaviour
- How we think, feel, behave according to physical factors within the body
Define physiology:
the study of the body and its parts and how they function
What are the assumptions of the biological approach?
- Everything psychological is at first biological
- Human behaviour as a physiological cause which may be genetically or environmentally altered
- Genes affect behaviour and influence individual psychological difference
- Mind lives in the brain
How does the cognitive approach differ from the biological approach according to the mind and the brain?
Cognitive believe brain and mind to be separate whilst biological believe the mind lives in the brain
What is meant by the genetic basis of behaviour?
Determine and provide evidence for the extent to which behaviours, or characteristics such as your IQ are the product of inheritance
How can you investigate the genetic basis of behaviours?
- Twin studies
- Family studies
- Adoption studies
- Selective breeding
What are twin study?
Studying twins in order to investigate the genetic basis of behaviour
What are monozygotic twins?
Share 100% of the same genes so are identical
What are dizygotic twins?
Have different genes so non-identical
What do concordance rates refers to?
The extent to which a pair of twins share similar traits or characteristics
What are adoption studies?
Comparing a trait or characteristic between adopted children and their biological or adoptive parents.
Define genes:
Basic units of heredity
How do genes functions?
In pairs
What do the recombination of the parents genes from the parents do?
Provide the basis of genetic variability
