Explain why the heritability of intelligence appears to increase with age, and the shared environment component appears to decrease with age.
What will be an ideal response?
The ideal answer should include:
1. Evocative and active gene-environment correlations- instances in which children's genetic tendencies lead them to have different experiences from other children-become more important with age, making the experiences of genetically related children more similar than those of genetically unrelated children.
2. As variation in the environment decreases (for example, through exposure to formal schooling), the proportion of the total variance in a trait that is due to genes automatically increases.
