biological approach

• What is the key assumption of the biological approach?


  Behaviour is driven by our biology.
• What physiological processes are included in the biological approach?


  Neurotransmitters and physiological disorders.
• What drives behaviour according to genetics?


  Inherited genes.
• What is the interaction that drives behaviour in genetics?


  The interaction between genes and the environment.
• What methods are used to investigate genetics in behaviour?


  Family studies, adoption studies, and twin studies.
• Why do researchers conduct twin studies?


  To assess genetic influence on behaviour.
• What does it suggest if concordance rates are similar in monozygotic (MZ) and dizygotic (DZ) twins?


  It supports the idea that behaviour is likely to be environmental.
• What does a higher concordance rate in MZ twins suggest?


  It suggests a genetic influence on behaviour.
• What is the main idea behind evolution and behaviour?

  Behaviours that help survival and reproduction are adaptive.
• How does aggression relate to evolution and behaviour?


  Aggression may increase access to resources and females.
• What is an example of a maladaptive behaviour mentioned in the study material?


  Preference for high-calorie food.
• What role do neurotransmitters play in the brain?


  They carry messages between nerve cells.
• What is the space between nerve cells called?

  The synapse.
• What have correlational studies found regarding neurotransmitters?


  There is a relationship between neurotransmitter levels and psychological abnormalities.
• What psychological abnormality is associated with too much dopamine?


  Obsessive-Compulsive Disorder (OCD).
• What psychological abnormality is linked to too little serotonin?


  Depression.
• What are the strengths and weaknesses of the biological model?


  Strengths:

  • Can be scientifically objectively tested.
  • Scans provide evidence for brain roles.

  
  

  Weaknesses:

  • Reductionist view of behaviour.
  • Deterministic perspective on behaviour.
  • Removes individual responsibility.
• What is a potential benefit of identifying genetic causes for diseases?


  It can lead to advancements in treatment.
