Document Summary
Some evidence of continuity (ex: fagan test, babies look @ 2 slightly different images and those who look at the new one have higher iq. ) Iq becomes stable across to adulthood. (degree of stability decreases as time period between tests increases, also depends on age child is assessed-as they get older less drastic changes occur. ) Iq somewhat genetic: family studies/kinship studies (genetic relations: 50% between parent & child and siblings, 25% between grandparents, 12. 5 for cousins. ) Twin studies (identical more similar than fraternal, need to consider environmental factor. ) Heritability=proportion of variance in a trait that can be attributed to genetic variance in sample. Environment effects on iq: research with home (home observation for measurement of environment. ) assesses quality of early childhood environment. Home, the better a child develops: cross-cultural research: family environment affects mathematics success (cultural differences and beliefs, focus on effort vs ability and offering help to kids. , ethnicity and environment: more variability within groups than between groups.
