Holism vs reductionism ID Flashcards
holism
it is inappropriate to divide the human experience into separate components because they loose meaning
reductionism
the belief that human behaviour is best understood by studying the smaller constituent parts
levels of explanation
The idea that there are several ways that can be used to explain behaviour
Biological reductionism
a form of reductionism which attempts to explain behaviour at the lowest biological level
environmental reductionism
The attempt to explain all behaviour in terms of stimulus-response links that have learned through experience
humanistic approach
holistic
behaviourist approach
reductionist
holism explanation
- Looks at behaviour as a ‘whole’
- Gestalt psychologists: ‘whole is greater than the sum of its parts’
- Humanistic psych focuses on the individuals experience as a whole by using qualitative methods to investigate themes rather than breaking behaviour down into components
reductionism explanation
- Breaks behaviour into constituent parts
- Parsimony: all phenomena should be explained using the simplest principles, being economical
biological reducitonism examples
- Neurochemical, physiological, evolutionary and genetic influences
- Arguments often work backwards
environmental reductionism examples
Behaviourist approach: all behaviour is learned through interactions with the environment and conditioning
high levels of explanation
many, more complex, wider, holistic
low levels of exlpanation
fewest, simplest, smallest, narrower, reductionist
levels of explanation order
- Socio-cultural level (society, media, peers, family)
- Psychological level (mind eg cognitive and psychodynamic approach)
- Physical level (actions/observable behaviours eg conformity)
- environmental/behavioural level (stimulus-response eg conditioning)
- Physiological level (eg localisation of function)
- Neurochemical level (neurotransmitters)
practical value
limitation
- Holistic accounts of human behaviour are more complex and hard to use
- Eg in regards to depression, there are many factors, so which is most influential?
- It is then difficult to know which to prioritise in therapy
Holistic accounts may lack practical value
scientific approach - reductionist
strength
- Experimental reductionism
- Operationalise variables ie break them down
- Possible to conduct experiments/observations in a reliable and objective way
- If you have an IV and a DV you can claim cause and effect
- Eg strange situation is operationalised eg stranger anxiety
Gives psychology greater credibility with natural sciences
counterpoint to scientific
limitation
- Reductionist approaches oversimplify complex theories, reducing validity
- Biological explanations do not include analysis of the social context where the behaviour occurs
Reductionist explanations can only form part of an explanation
higher level - Reductionism can’t explain behaviours at a higher level
limitation
- Aspects of social behaviour only emerge in a group context
- Eg the effects of conformity to social roles in the stanford prison experiment
- Interaction between people and group was important
- No ‘conformity’ gene
Higher level explanations provide a more valid account
