PSYC12H3 Lecture Notes - Lecture 7: Twin, Nature Genetics, Heritability
Document Summary
Novolitional responses responses that come up when threatened. But black iq is supposedly at the lower end. We have no idea of the origin of this test or if it"s biased or whatever. Intelligence is highly heritable: high correlation between parent iq and child iq, this may be cultural values and environment though. Iq of identical twins is highly related; more than fraternals. Iq of identical twins reared apart is highly related. Iq of adopted children is related to iq of biological mother, less related to iq of adopted mother. Iq of identical twins reared apart is less related than iq of identical twins reared together. Iq of fraternal twins is more strongly related than iq of regular siblings. Iq of adopted children is more similar than unrelated individuals reared apart. Impoverished environments related to lower iq: longer you are exposed to poor environment, the lower your iq.
