You need to know about how behaviour is influenced by…

  • genes (including genotype, phenotype and the role of evolution)
  • biological structures
  • neurochemistry

Some key assumptions of the biological approach in psychology:

  • patterns of behaviour can be inherited
  • animal research may inform our understanding of human behaviour
  • cognitions, emotions and behaviours are products of the anatomy and physiology of our nervous and endocrine systems
