  any internal biological influence on beheaviour e.g., genes, neurotransmitters, it proposes our behaviour is innate

  • genetic inheritance
  • neural mechanisms
  • hormones
• hereditary

  • The process by which traits are passed from parents to their offspring
  • usually referring to genetic inheritance
• Examples:

  •  Genetic explanations — more closely related two individuals are, the more likely that they will develop the same behaviours. The concordance rate for sz- 40% for MZ twins and 7.4% for DZ twins. not 100%, despite being genetically identical. This suggests the environment also play a significant role in development. 
  • Evolutionary explanations — These are based on the principle that a behaviour which promotes survival will be naturally selected e.g., running away from fire. This is because behaviours are adaptive(bowlby)
