Reductionism vs Holism Flashcards
Define ‘reductionism’.
Based on the scientific assumption of parsimony in which a complex phenomena can be explained by studying specific parts.
Give an example of reductionism in psychology.
Using memory recall of a crime to represent accuracy of memory as a whole.
Define ‘holism’.
Studying the whole of something due to the specific parts not being enough of an explanation.
Give an example of holism in psychology.
Case studies of criminals to understand why they offended.
How does reductionism study behaviour?
Breaking down complex phenomena into simpler components to measure for scientific testing.
How does holism study behaviour?
Observing and studying the complex phenomena as a whole without breaking it down to simplify it.
Identify 3 areas of Cognitive Psychology that are considered reductionist.
1) Memory models
2) Studies on memory
3) Brain scanning
Describe how memory models in Cognitive Psychology are considered reductionist.
- MSM reduces memory into 3 stores: sensory store, STM, and LTM
- WMM reduces STM into 4 separate stores: central executive, phonological loop, visuospatial sketchpad, episodic buffer
- Tulving’s theory separates the types of memories into 2: semantic, episodic
Describe how lab experiments in Cognitive Psychology are considered reductionist.
- They operationalise memory into variables of recalling word lists (e.g. Baddeley 1966)
- They operationalise memory into variables of recalling digits in order (e.g. Sebastian and Hernandez-Gil 2012)
- Measuring memory is often quantitative (e.g. number of words recalled correctly)
Describe how brain scanning in Cognitive Psychology are considered reductionist.
- It reduces memory down to the activity of specific areas of the brain
- It ignores how areas of the brain interacts with the area being studied
- Doesn’t measure brain activity as a whole
Identify 2 areas of Cognitive Psychology that are considered holistic.
1) Schemas
2) Case studies
Describe how schemas in Cognitive Psychology are considered holistic.
- Bartlett’s theory looked at how are experiences (schemas) shape our memory
- He does this through looking at memory as a whole in how the schema changes it instead of breaking it down
Describe how case studies in Cognitive Psychology are considered holistic.
- Case studies view the individual’s memory as a whole
- Research is based on experiences in their life instead of one specific factor
- Uses many different types of methods to assess providing both quantitative and qualitative data
Evaluate the reductionism and holism of Baddeley (1966).
Reductionist
- Operationalised memory into a list of 10 words that were semantically and acoustically similar and dissimilar
- The number of words recalled indicated how good memory was
- The number of acoustic and semantic words recalled in different trials indicated the encoding of the STM and LTM
Identify 4 areas of Social Psychology that are considered reductionist.
1) Studies on obedience
2) Theories of obedience
3) Studies on prejudice
4) Theories of prejudice
Describe how studies on obedience in Social Psychology are considered reductionist.
- Milgram (1963) operationalised obedience as a voltage for giving people electric shocks that would increase in power
- Milgram’s variations that tested situational factors individually such as a run down office block, the number of people conforming, etc
Describe how theories of obedience in Social Psychology are considered reductionist.
- Agency Theory reduces obedience down to being in the agentic state as a result of obeying authority
- Social Impact Theory reduces factors affecting obedience down to 3 things: number, proximity, and power
- Authoritarianism reduces obedience down to having a specific personality involved with certain traits: hostility towards minority groups and obsession with ranks
- Locus of control reduces obedience down to having a personality which makes you more likely to obey being an external locus of control
Describe how studies on prejudice in Social Psychology are considered reductionist.
- Sherif (1954) operationalised prejudice as attitudes towards an out-group being hostile
- Sherif (1954) also reduced the conditions for prejudice to arise being down to competition for resources
- Reicher and Haslam (2006) reduced conditions for prejudice down to the inequality of power between two groups
Describe how theories of prejudice in Social Psychology are considered reductionist.
- Realistic Conflict Theory reduces the conditions for prejudice down to competition for resources and also reduces the solution to superordinate goals
- Social Identity Theory reduces the rise of prejudice down to 3 stages: social categorisation, social identification, social comparison
Social Identity Theory also reduces reason for identifying with a group down to sharing characteristics - Contact Hypothesis reduces the solution for prejudice down to increasing contact between two groups
- Authoritarianism reduces the reason for prejudice down to having a specific personality involved with certain traits: hostility towards minority groups and obsession with ranks
Evaluate the reductionism and holism of Sherif (1954).
Reductionist
- Reduced reason for prejudice as competition
- Operationalised prejudice as hostility towards out-groups with friendship levels
- Reduced the hostility down to verbal and physical aggression
- Only considered situational factors affecting obedience
- Reduced solution to complexity of prejudice down to superordinate goals
Identify 2 areas of Biological Psychology that are considered reductionist.
1) Theories of aggression
2) Brain scanning
Describe how theories of aggression in Biological Psychology are considered reductionist.
- Evolution reduces aggression down to biological causes of having a gene that aided survival which is innate
- Brain structure reduces aggression down to abnormality in the brain causes by damage to certain places such as the prefrontal cortex which is responsible for self-control and so someone is more likely to be impulsive if its damaged
- Neurotransmitters reduce aggression down to an imbalance of dopamine and serotonin in which increased dopamine and low levels of serotonin causes aggression
- Hormones reduce aggression down to an imbalance of testosterone and cortisol in which higher levels of testosterone causes aggression with cortisol being responsible for regulation of stress
