AO3

• Holism:

  Pros:

  • ecological validity - behaviour is very complex and it accounts that

  Cons:

  • Occham's razor - overcomplicates behaviour when it may be more simple
  • Can't be scientifically falsified - too complex
  • Difficult to establish cause & effect - behaviour is too complex
• Reductionism:

  Pros:

  • Allows scientific methods - isolate the variables e.g genes in schizophrenia
  • Allows the DSM - V to develop by understanding the genetic impacts on mental disorders

  Cons:

  • Lacks ecological validity - behaviour is very complex
  • Doesn't address societal problems e.g poverty, discrimination
