nature vs. nurture Flashcards
nature
argues that behaviours are innate and caused by internal factors - look at roles of biology (evolution, genes, NTs, hormones and brain structures)
nurture
argues that behaviours are a result of external environmental factors - social interactions shape how we behave
interactionist approach
aims to combine nature and nurture by looking at how genes and our environment interact to determine personality
why is nature v nurture a debate
aims to explain behaviour, cognition and varying approaches fully
stress-diathesis model
argues that both a genetic predisposition and appropriate environmental trigger are required for a condition to develop
e.g. epigenetics
support for stress-diathesis model
Finnish Adoption Study - 155 adopted children with bio mothers with SZ compared to matched group with no family history of SZ
group with SZ mothers had 10% rate of SZ and all of reported cases came from ‘disturbed’ families so when family environment rated at ‘healthy’ SZ didn’t occur even in high risk sample
conclusion
widely accepted that both nature and nurture form a continuum and interact
beneficial to adopt an interactionist view e.g. stress-diathesis model would be more comprehensive to study disorders such as SZ or AN
