biological approach

• behaviour driven by biological, physiological forces - genes, neurotransmitters in biological structures and processes
• environmental triggers
• behaviour is the result of innate biological factors
• creates universal laws using human physiological explanations
• genetic inheritance
• genetic vulnerability
• interactionism - our environment interacts with our biology and visa versa
• twin studies

  • monozygotic (identical) 100% genes shared
  • dyzygotic (non identical) 50% genes shared
• ✔️scientific methods - reliable data
• X biologically deterministic - sees behaviour as governed by internal biological causes where we have no control
• X biologically reductionist - breaks behaviour down into biological processes
