NATURE – NURTURE DEBATE:
o Extent to which aspects of behaviour are due to inherited or acquired characteristics and the
contribution of each of these influences.
When writing answers, only say debate if you refer to both sides but if only 1 say nature or nurture
approach/perspective.
NATURE: NURTURE:
o Those who study this are nativists. o Those who study this are empiricists.
o Nativists like Descartes (1596-1650) argues o John Locke (1632-1704) argued the mind is
human characteristics (and some aspects a blank slate (Tabula Rasa) that learning,
of knowledge) are innate. and experiences write on
o This is due to heredity (nature) o This is due to the environment (nurture)

HEREIDTY AND THE ENVIRONMENT:
o Heredity: genetic transmission of mental and physical characteristics from one generation to
another
o Environment: influences on human behaviour that aren’t genetic, from pre-natal influence on
cultural/historical influences at a societal level.
o Relative importance of heredity and the environment: Lerner suggests environmental influences
begin as soon as we’re born (or even earlier) so it’s impossible to answer the nature-nurture
question. Both are so intertwined that it makes no sense to separate them but it’s better to study
the extent to which they influence our thoughts/behaviours. Known as interactionist approach.
INTERACTIONIST APPROACH:
o Idea nature and nurture are linked so we don’t study both separately but study how they interact
and influence each other.
o For example: attachment patterns between infants and parents. A child’s innate temperament
influences the way a parent responds wo will in turn affect the Childs behaviour, so nature
creates nurture. Heredity and the environment interact.
HERITABILITY CO-EFFICIENT:
o Contribution of nature can be measured by a heritability co-efficient.
o A No from 0-1 indicates the extent to which a characteristic is genetic (1= genetic)
o For example, IQ = 0.5 so suggests that genetics and environment are important in the
development of intelligence
EVALUATION:
IMPLICATION: DEVELOPMENT OF ARGUMENT 1:

‘good of everyone.’
o Both positions of the debate are taken
to extremes so have negative
consequences for society, so an
interactionist approach is favoured.

FREE WILL V DETERMINISM:
FREE DETERMINISM:
WILL:
o Notion o View an individual’s behaviour shaped/controlled by internal or external forces
that rather than their will to do something.
humans Hard determinism: free will not possible as behaviours due to external/internal
can make forces beyond our control (compatible with science)
choices Biological determinism: Behaviours due to biological factors e.g., genes, hormones,
that evolution that we can’t control.

d by Environmental determinism: Belief behaviours due to features of the environment

or Psychic determinism: Behaviours due to unconscious conflicts and childhood

forces. Soft determinism: All events, human behaviour, have causes but behaviour can also
be determined our conscious choices in the absence of coercion. There’s a
distinction between behaviour highly constrained by a situation (hard, involuntary
behaviour) and modestly constrained (soft, voluntary behaviour). For e.g., child
apologises for swearing because they’ll be punished if they dint (hard determinism)
or because they’re genuinely upset at being offensive (soft determinism). Behaviour
that’s highly constrained is easier to predict

Scientific emphasis on causal explanations:
o Science says every event has a cause that can be exp using general laws. This allows scientists to
predict/control future events.
o Use of lab experiments lets psychologists predict/control behaviour.
