Reductionism is the belief that human behaviour can be explained by breaking it down into simpler component parts. Those who take a reductionist position believe that the best way to understand behaviour is to look closely at the parts that make up our systems, and then use the simplest explanations to understand how they work. The reductionist approach suggests that there are different levels of explanation. The lowest level considers physiological (biological) explanations, where behaviour is explained in terms of neurochemicals, genes and brain structure; the middle level considers psychological explanations (e. g. cognitive and behavioural) and the highest level considers social and cultural explanations, where behaviour is explained in terms of the influence of social groups.

Levels of Explanation ❖ Biochemical and physiological ❖ Psychological ❖ Social and cultural Levels of explanation - the idea that any behaviour can be explained at different levels of reduction such as physiological, psychological or social and cultural level.

Aggression can be explained at a biological level in terms of hormones (e. g. testosterone) or brain structure (e. g. the amygdala); at a psychological level through either operant conditioning or observation and imitation (social learning). Furthermore, it could also be explained in terms of cultural norms. The experience of love can be simply explained by the increase in the hormone oxytocin. This would be a reductionist explanation. AT what level?

Types of Reductionism ❖ ❖ ❖ Biological Reductionism Animals are made up of atoms so it should be possible to explain human behaviour at the level of neurons, neurotransmitters, hormones etc. You could give the dopamine hypothesis as an example. Environmental Reductionism The behaviourist believe that behaviour can be explained in terms of stimulus – response links. Examples of this are the attachment process – building associations between the mother and food. The development of phobias – building associations between a stimulus and fear.

What is Holism ❖ ❖ Here we consider that people are more than a sum of their parts. Treat the person as an entire human not a number of parts. This was put forward by Roger's and client entered therapy. This is a rejection of behaviourist and psychodynamic therapies.

Humanistic Approach and Holism ❖ ❖ ❖ This is the best example of a holistic approach in psychology We respond as a whole individual rather than just a series of S-R links. If we do not consider people as a whole and if there is a lack of identity or wholeness this can lead to mental illness.

What is the problem with a Reductionist View? ❖ ❖ Lower levels of explanation may only explain part of the story. Biological and environmental determinism taken in isolation may mean we lack understanding of behaviour. This may distract from a more appropriate explanation. For example giving someone with psychosis antipsychotics may not consider the importance of family interaction styles and environmental stressors.

Evaluation of Biological and Environmental Reductionism ❖ The development of drugs ❖ But ignores the psychological processes involved. ❖ The use of non-human animals ❖ Quantitatively different? ❖ Cognitive and emotional factors? ❖ Choose two of these to PEEL
