Holism & Reductionism Flashcards
Tell me about it not being a continuum
What are the key concepts of the debate
HRLBE
Holism
Reductionism
Levels of explanation
Biological reductionism
Environmental reductionism
What is Holism
Proposes the idea that it only makes sense to study a whole system - the whole is greater than the sum of its parts
What is Reductionism
Based on the scientific principle of parsimony - that all phenomena should be explained using the simplest principles
What is Biological Reductionism
Suggests all behaviour can be explained through neurochemical, physiological, evolutionary and/or genetic influences
What is Enviornmental reductionism
Proposes that all behaviour is acquired through interactions from the environment ie the behaviourist approach
Levels of explanation
For example, OCD can be understood in different ways:
- Socio-cultural level - behaviour most people would regard as odd
- Psychological level - individual’s experience of having obsessive thoughts
- Physical level - sequence of movements, ie washing hands
- Neurochemical ;eel - underproduction of serotonin
Can argue about which is the ‘best’ explanation of PCD, but each level is more reductionist than the one before
What are strenghts and limitations?
Strength: Reductionism and scientific status
Limitation: Holism may lack practical value
Need for higher level explanations for reductionism
Brain and mind
Tell me about the strength of reductionism
In order to conduct well-controlled research, variables need to be operationalised (target behaviours broken down into constituent parts)
This makes it possible to conduct experiments or record observations (behavioural categories) in a way that is objective and reliable
This scientific approach gives psychology greater credibility, placing it on equal terms with the natural sciences
Tell me about the limitation of holism and practical value
Holistic accounts of human behaviour become hard to use as they become more complex with presents researchers with a practical dilemma
If many different factors contribute to, say, depression, then it becomes difficult to know which s most influential and which to priotise for treatment
This suggests that holistic account may lack practical value (whereas reductionist accounts may be better).
Tell me the limitation of the need for higher level explanations
There are aspects of social behavioir tht only emerge withina group context and cannot be understood in the terms of the individual group members
For example, the Stanford prison study could not be understood by observing the particiapnts as individuals, it was the behaviour of the group that was important
This shows that, for some behaviours, higher (or even holistic) level explanations provide a more valid account
Tell me about the brain and mind evaluation
A reductionist account of consciousness would argue that we are thinking machines - that cognitive processes are associated with physical processes in the brain
On the other hand, neuroscientists struggle to explain the subjective experience of the same neural process. This is referred to as the ‘explanatory’ gap in brain science.
This suggests that not all aspects if consciousness, particularly individual differences in experience, can be explained by brain activity
