Nature Vs Nurture Flashcards
whats the order of approaches from nature to nurture?
Biological
Psychodynamic
Cognitive
Humanism
Behavourism
what is the nature-nurture debate?
concerns the origin of our traits. its concerned with the extent to whixh aspects of behaviour are a product of inherited or acquired characteristics.
what does nature mean?
-view that behaviour is product of innate biological or genetic factors.
-psychologist have known certain physical characteristics such as eye colour, skin pigmentation and certain diseases are biologically determined and the result of heredity.
whats being on the nature side called?
-known as the nativist position
-basic assumption is that the characteristics of human species are product of evolution and
-individual differences ar result of each person’s each genetic code.
what is heredity?
-process in which traits are passed down from one generation to the next.
-characteristics like height, weight, hair loss to specific illnesses +vely correlated with genetic relatedness
how do we measure heredity?
-heritability coefficient is used to assess heredity.
-its numerical figure ranging from 0 to 1.0.
-indicates extent to which a characteristic has genetic basis.
what do family, twin and adoption studies show?
-show the closer the relatedness of two people, the more likely it is that they will show same behaviours.
-e.g risk of having schiz is 1%
Gottsman and Shields (1991)
-pooled the results of around 40 family studies and found that risk increases to 46% for those with two parents who have schizophrenia
Joseph (2004)
-pooled the data for schizophrenia studies conducted before 2001 and found an average concordance rate of 40.4% for MZ twins and 7.4% for DZ twins highlighting signifiant genetic component
what are evolutionary explanations?
-they also emphasise the importance of nature
-they assume that behaviours or characteristic which increase our chances of survival and reproduction will be naturally selected
-genes for these characteristics or behaviours will be passes on as they provide adaptive advantage.
what is the nurture view?
nurture is the view that behaviour is the product of environmental influences
what are people who take the nurture view called?
environmentalists or empiricists
what do empiricists believe?
-the mind is a blank state (tabula rasa)
-they state human characteristics are learnt and as a result of the environment.
what is the environment?
any influence on human behaviour that is non genetic
what did Richard Lener do?
first identified two levels of the environment: pre natal and post natal experiences.
this ranges from pre natal influences in the womb through to cultural and historical influences at a societal level.
