IQ cont...psychology notes

IQ is fairly stable, yet may change with age and experience.  IQ reveals one's standing relative to others who are the standardization samples. IQ reveals aptitude as well as the extent to which one has learned information and skills.  Schooling and general cultural experience influence IQ.  Brofenbrenner (1970's) found in a study of identical twins raised in separate households, differences in IQ were related to amount of schooling.
