holism / reductionism Flashcards
what is the holism / reductionism debate concerned with
the level at which it is appropriate to explain human behaviour
define holism
- idea that behaviour must be viewed as a whole
- we cannot predict how the whole system will behave by only looking at the individual components
give examples of holism from research
- MENTAL DISORDERS - viewing whole experience rather than individual factors
- HUMANISM - individuals react as organised whole
- COGNITIVE PSYCHOLOGY - memory networks behave differently as a whole than when individual parts are separate
define reductionnism
belief human behaviour can be explained by breaking it down into individual components
define levels of explanation
- for any behaviour there are many different possible levels of explanation
- the debate asks if it is appropriate to look at one level specifically and whether it will tell you enough about human behaviour
outline and explain the first level of explanation
- SOCIAL AND CULTURAL EXPLANATIONS
- eg. memory; research suggests cultural expectations affect what we remember and how we recall it
outline and explain the second level of explanation
- PSYCHOLOGICAL EXPLANATIONS
- eg. memory; cognitive psychologists study particular aspects eg duration and capacity
outline and explain the third level of explanation
- BIOLOGICAL EXPLANATIONS
- eg. memory; found association between size of hippocampus and memory for spatial navigation
define biological reductionism
- explanations of behaviour can be reduced to work of chemicals/neurotransmitters/hormones
- eg. excess dopamine = schizophrenia
define environmental reductionism
- explanations of behaviour due to stimulus-response links
- attachment to mother caused by her providing food - rewarding
outline the strengths of the holism side of the debate
- looks at all factors that may impact behaviour
- does not ignore complexity of behaviour
- looks at different components to understand person as a whole
- higher ecological validity
outline the weaknesses of the holism side of the debate
- over complicates behaviours
- not scientific
- hard to determine cause and effect
- neglects importance of biological explanations
- almost impossible to study all factors influencing behaviour
outline the strengths of the reductionism side of the debate
- scientific as it requires isolation of variables
- led to development of effective chemical treatments
outline the weaknesses of the reductionism side of the debate
- can be over simplistic so lacks ecological validity
- does not address larger societal issues such as poverty
