The biological approach

• What does having genetically determined behaviour- which enhances survival and reproduction lead to?

  Adaptive advantages
• What does the biological approach emphasize about behaviour?

  It is governed by internal causes
• What is a strength of the biological approach?

  Use of scientific methods
• How does the biological approach contribute to mental health treatment?

  It leads to psychoactive drug development
• What is a limitation of the biological approach?

  It has a deterministic view of behaviour
• What does the biological approach suggest about the mind and body?

  They are one and the same
• What is the role of twin studies in the biological approach?

  To investigate the genetic basis of behaviour
• What are higher concordance rates indicative of in twin studies?

  Genetic similarities in behaviour
• What is the difference between genotype and phenotype?

  Genotype is genetic makeup; phenotype is expression
• How does the environment influence phenotype?

  It affects how genes are expressed
• What does the theory of evolution suggest about behaviour?

  Behaviours enhancing survival are passed on
• What are the strengths and weaknesses of the biological approach?

  Strengths:

  • Use of scientific methods
  • Real-life applications in mental health

  
  

  Weaknesses:

  • Deterministic view of behaviour
  • May overlook environmental factors
• How do genes and environment interact in the biological approach?

  • Genes influence behaviour (genotype)
  • Environment affects gene expression (phenotype)
  • Interaction shapes overall behaviour
