the nature-nurture debate Flashcards
explain the Nature Debate
- NATIVISTS
- human characteristics are innate due to heredity
- heritability coefficient shows that the general figure for heritability in IQ= 0.5
- shows genetics and environment are important factors in intelligence
what is the heritability coefficient?
- ranges from 0-1
- indicates the extent to which a characteristic has a genetic basis
- 1= entirely genetically determined
explain the Nurture debate?
-EMPIRICISTS
-mind is a blank slate (john locke TABULA RASA) and built through learning
-different levels of environment
-pre-natal= during pregnancy
-post-natal social experiences
as child grows up in social
context
evaluate controversy of Nature-Nurture debate?
- nativists believe genetic makeup determines our characteristics whilst environment has little impact
- bad as attempts to link race, genetics and intelligence BIOLOGICAL
- this hard determinist stance contrasts to empiricists who argue behaviour can be changed by altering the environment = reinforcement of a desirable characteristic ENVIRONMENTAL
- may lead to society that manipulates using this technique
evaluate inability to separate nature and nurture
WEAKNESS
- people create their nurture by seeking out environments that r appropriate for their nature
- aggressive children feel more confident with kids with similar dispositions
- this affects development
- niece-picking
- impossible to separate nature and nurture
explain the interactionist approach?
- child’s temperament will influence how parent responds and response will affect child’s behaviour
- therefore nature creates nurture, both hereditary and environmental impacts
explain the diathesis-stress model?
-psychopathology is caused by biological and genetic vulnerability which is ONLY expressed when coupled with a biological/environmental trigger
explain the difference between the diathesis-stress model and the interactionist approach?
- diathesis believes in a vulnerability that ONLY expressed due to trigger
- interactionist believes hereditary and environmental factors work together
evaluate problem with MZ and individual differences?
- MZ twins DONT have 100% concordance rate thats shows hereditary factors and environment cannot be separated
- mz siblings may experience things differently eg… divorce of parents
- Therfore environmental influences are had to separate from hereditary factors
what study supports the diathesis-stress model?
-group of Finnish adoptees, those most likely to develop Schizophrenia had relatives with the disorder (VULNERABITY) and had dysfunctional relationships with adoptive families (TRIGGER)
