biological approach

• what is the biological approach ?

  importance of physical processes on behaviour such as genes , neurochemistry etc
• how would charles darwin explain behaviour ?

  process of natural selection - survivial of those best adapted then passing on the genes
• what is a genotype ?

  set of genes - genetic makeup
• what is a phenotype ?

  observable characteristics from both genes and enviroment
• how does brain structure influence our behaviour ?

  brain regions control diff functions
• what is neurochemistry ?

  chemicals in our brain
• how does neurochemistry influence our behaviour ?

  neurochemical imbalances create abnormal behaviour
• what is the evaluation of the biological approach ?

  reductionist - just physical processes , ignores enviroment

  scientific methods - eg scanning techniques

  good real life application - eg psychoactive drugs
