Biological Approach

• What biological structures influence behaviour?

  Brain, nervous system, and endocrine system
• How are specific areas of the brain linked to behaviour?

  They are associated with specific behaviours and mental processes
• What is the genetic basis of behaviour?

  Passed down through generations
• What are genotypes and phenotypes?

  Genotypes are genetic makeup; phenotypes are expressed traits
• What role do neurotransmitters play in behaviour?

  They regulate behaviour and mental health
• What can imbalances in neurotransmitters lead to?

  Disorders like depression
• How has human behaviour evolved?

  Through natural selection to adapt to challenges
• What do twin studies assess?

  Concordance rates in MZ and DZ twins
• What techniques are used for brain scanning?

  fMRI and PET scans
• What do drug studies assess?

  Effects of chemical interventions on behaviour
• What are the strengths of the biological approach?

  • Effective real-world applications
  • Understanding of neurotransmitter imbalances
  • Development of treatments like SSRIs
• What are the weaknesses of the biological approach?

  • Overly deterministic perspective
  • Ignores free will and personal responsibility
  • Limits explanation of human agency
• How does the biological approach enhance scientific credibility?

  • Uses objective methods like brain scans
  • Provides replicable data
  • Supports validity of biological explanations
• What did Raine et al.'s research demonstrate?

  Link between biological differences and behaviour
• What are the limitations of brain scanning methods?

  • Can oversimplify findings
  • Correlation does not imply causation
  • Environmental factors may interact with biology
