Reductionism + Holism Flashcards
reductionism
= the scientific view that human behaviour is best explained by breaking it down into simpler component parts
biological reductionism
= refers to way psychologists reduce behaviour to its physiology (physical) + explain it in terms of genetics, neurotransmitters, hormones, biological structures
environmental reductionism
= reduces behaviour to simple stimulus-response (e.g. conditioning)
parsimony
= idea that complex behaviour should always be explained in simplest parts
levels of explanations
= Rose (1976):
– highest level (more holistic) = social + cultural explanations
– middle level = psychological explanations
– lowest level (more reductionist) = biological explanations
holism
= argument that human behaviour is too complex to be broken down into simpler parts - consider ‘whole’ individual as sum of its parts
reductionism - assumptions…
…behaviour best understood if we explore parts contributing to system
– based on scientific assumption of parsimony - similar to concept of Occam’s Razor which argues answer to any problem is often the simplest explanation
bio reductionism - Sz…
…theory that Sz caused by excessive activity of neurotransmitter dopamine is reducing Sz to the single biological component of dopamine
environmental reductionism - behaviourists…
…support concept of classical conditioning - assumes behaviour can be reduced to stimulus-response (S-R) where behaviour shaped by learnt associations
– complex behaviours explained by series of S-R chains
enviro reductionism - attachment…
…infant responds w/ pleasure when CG feeds them - learnt association formed + CG becomes CS who creates CR of pleasure in infant
levels of explanations - examples…
…bio = explained in smallest parts e.g. genetics, neurochemicals + bio structures
– psych = e.g. cognitive + behavioural (machine reductionism etc)
– social + cultural = e.g. influence of social groups
levels of explanations - memory…
… 1. S+C = Barlett’s schema theory - culture - socially learnt schemas affect what we remember + how we recall
- P = theoretical models such as multi-store model of memory - evidence from Miller + Peterson and Peterson
- B = memory found to be localised in areas of brain e.g. hippocampus
levels of explanations - gender…
… 1. S+C = Mead conducted research into cross cultural differences in gender roles + found gender was shaped by social factors + cultural norms
- P = Kohlberg explains gender develops as child progresses through stages of cognitive intellectual development
- B = gender explained as result of action of sex hormones e.g. higher levels of testosterone in males which has not been used to explain masculine behaviour
holism - assumption…
…human behaviour should be viewed as a whole integrated experience + not through separating its parts
holism - supported by…
…Gestalt psychology - explores how we perceive something in real world as a whole rather than as collection of pieces
– only make sense of + perceive world accurately through considering whole image - therefore by separating human behaviour into parts this means complex behaviour can be easily misunderstood
