Reductionism and Holism

Cards (14)

  • What is Reductionism?
    The view that we can understand things by breaking them down into simpler parts.
  • What is Holism?
    The view that, to understand something, we must look at it as a whole.
  • As we go down the levels of explanation (within psychology) the explanations are seen as more reductionist.
  • The most reductionist level of explanation is a biological explanation, because it involves explaining behaviour in terms of the simplest parts: tiny genes in the body.
  • What is biological reductionism?
    When we explain behaviour in terms of neurotransmitters, hormones and genes.
  • What is environmental reductionism?
    When we explain behaviour in terms of stimulus and response.
  • Where do each of the approaches stand on the reductionism vs holism debate?
  • Reductionist explanations are scientific because they reduce behaviour down to cause and effect relationships that are empirically testable, and therefore falsifiable.
  • Very holistic explanations can’t be studied scientifically, because they insist that we shouldn’t break down behaviour into cause and effect relationships.
  • What is the principle of parsimony?
    If there are several different explanations that completely explain something we should choose the simplest explanation.
  • What strengths are there of the Reductionist approach?
    • Supported by principle of parsimony
    • Can be used to treat symptoms of mental disorders
  • What limitations are there of the Reductionist approach?
    • Can be more effective to consider more holistic explanations (CBT with relapse rates)
  • In the reduction-holism debate, interactionism is the interaction between different levels of explanation. One advantage of interactionism is that it fits the evidence we have about the causes of conditions like depression.
  • What are the 2 problems with interactionism (in relation to the reductionism vs holism debate)?
    1. Involves more holistic levels of explanation, which are difficult to test scientifically
    2. Violates the principle of parsimony
