ID: Nature Vs Nurture Flashcards
What is the nature vs nurture debate?
Aspects of behaviour r products of inherited characteristics + how they interact
What is Nature?
Behaviour seen as a product of innate due to heredity/bio influences
Nurture
Behaviour = product of environmental influences (physical +social world)
Define Heritability
Proportion of differences between individuals in pop (due to traits)
Define Heredity
Genetic transmission of mental and physical characteristics passed from one gen to another
How can you measure Nat/nurt?
Concordance rates (fam/twin/adoption studies(similar behaviours)
What theory can cause schizophrenia due to contradictory messages?
Double bind theory
What is the percentage of the risk of diagnosed schizophrenia of the general population?
1%
What did gottesman and shields find in their study of 40 families?
The risk of schizophrenia increased to 46% for those whose parents had schizophrenia
What is the interactionist approach?
Process of nature and nurture working together
give an example of interactionist approach (Bowlby/kaggan)
Bowlby - baby’s att type determined by parental love (nurture)
Jerome kaggan - baby’s temperament affects relation (nature)
nature creates nurture - temperament = parents response
What is the diathesis stress model?
behaviour caused by bio/environmental vulnerability but only expressed by a trigger. e.g (person with low agression gene) may have experienced childhood trauma.
define epigenetics
The way our genes are marked, without our genes actually changing ( the way their switched on and off
give a strength of the nat/nurt debate
-the usefulness of adoption studies
-separate competing influences of nat/nurt
-kids similar/not sim to adopted + bio parents
- suggesting environment or bio may be stronger influence
-Rhee + waldman - meta analysis of adoption studies, found that genetic influences accounted for 41% of the variance in aggression
give a limitation/ counter of adoption studies as a strength of the nat/nurt debate
misguided approach as nat and nurt can not be simply pulled apart
-according to Plomin, people pick own nurture by selecting nature by actively seeking environments they may feel comfortable in.
-e.g. aggressive child may feel more comfortable around kids who show similar behaviours
-plomin refers to this as nice-picking
-suggests looking at evidence for nat/nurt may not be useful
