Document Summary
Reliability: test-retest relia(cid:271)ility r"s =. (cid:1010)(cid:1009) to . 80, means that when you measure iq at time 1 should be highly. But large fluctuations do happen: eg. New zealand longitudinal study: measured iq firs time when 7 then measure ever 2 years, over any 2 year period 1-% changed their scores by a sd which is big! Iq scores down = life situation happened (financial, mental) (cid:271)ou(cid:374)ce up maybe because of food thing that happens good environment. Iq usually settles around something independent to dow tih environment. Current and future academic performance: grades, number of years in school (eg. brody, 1997) Delinquency (teens) and criminal behaviour (adults) low iq. Part 2: effects of nature and nurture on intelligence. If intelligence fully inherited, then social programs not needed because its all about your genes so nothing from the outside would help. More genetically related you are, the higher the concordance on intelligence.
