Jake Venditto 2/4/10 Chow AP Psychology Chapter 9 Learning and Psychological Testing 15. The empirical evidence that shows how heredity affects intelligence is shown in the twin studies and adoption studies. In the twin studies show that although reared in different environments, these identical twins still display greater similarity in IQ than fraternal twins reared together. The adoption studies show that there are a lot of similarities between biological parents and child genetically. 16. A heritability ratio: An estimate of the proportion of trait variability in a population that is determined by variations in genetic inheritance. One limitation is that it’s a group study which means it can not be applied meaningfully to individuals. Also the heritability of a trait may vary group to group based on certain factors like the environment 17. One line of study is the adoption studies in which they studied twins and indicated that environment influences intelligence. They found that adopted children show some of a resemblance to their foster parents in IQ. They also found that siblings reared together are more similar in IQ than siblings reared apart. Another study is the cumulative deprivation hypothesis which say children who live in substantial areas will gradually have a decrease in their IQ. One other study is the home environment and schooling effects which show the correlation between the stable home life and good school life with better IQs. Lastly is the Flynn effect.
