holism and reductionism Flashcards
what is holism?
attempts to understanding human behaviour can only be done by analysing the person/the behaviour as a whole rather than constitutional parts
consider whole person’s experience:
- cognitive
- emotional
- social
- economic
what is reductionism?
- analysing behaviour by breaking down into constituent parts
- based around scientific principle of parsimony (all behaviour should be explained using the most basic - lowest levels - principles)
- consider major systems involved: biological (sera system) + behaviourist (learned behaviours + stimulus response then treat symptoms according to each system
what are the types of reductionism?
- biological
- environmental (stimulus-response)
- machine
what is biological reductionism?
explains social and psychological phenomena at a lower biological level - genes + hormones
example
- drugs that increase serotonin help treat ocd - low sera may cause - reduced ocd to NT activity
what is environmental reductionism?
explains all behaviour in terms of stimulus and response (physical level) and does not concern itself with mental processes (psychological level)
example
- learning theory of attachment - reduces love to learned association of person feeding and food which results in pleasure
what is machine reductionism?
suggests the brain is like a computer in terms of input-process-output
example
- models of memory (WMM and MSM) as they reduce the function of memory down into component parts
what are levels of explanation to explain behaviour?
low to high in reductionism
- socio-cultural level
- psychological level
- physical level
- environmental/beh level
- physiological level
- neurochemical level
what is a strength of reductionism when it comes to scientific research?
- has a scientific approach - cause-effect rship can be established between influence and behaviour
- breaking down behaviour makes it possible to conduct experiments and record observations objectively and standardised way - can be tested to be reliable
- SS broken down behavioural categories - can be repeated
how is oversimplification of behaviour a limitation of reductionism?
- reducing validity
- one level of explanation will disregard another so potentially ignoring a factor that could have a much larger influence on behaviour
- wolpe (1973) treated a woman for her fear of insects by systematic desensitisation - failed because he fear was of her husband with an insect nickname
- ignored context of phobia thus preventing an effective treatment
- reductionism only forms part of an explanation
how is a lack of practical value a limitation of holism?
- holism approach to human behaviour - hard when complex
- if accept humanistic perspective - many different factors that contribute to depression (rships, family circumstances)
- difficulty in knowing which to prioritise as basis for therapy as most influential unclear
how does holism increase understanding of behaviour?
- researchers can assess multiple factors that can contribute to psychological problem > focus on small constituent parts
- can decide which is most influential from both internal + external factors which more effective
