Briefly define heritability, shared environment and non-shared environment and explain what proportion of the variability in IQ they explain. How do the contributions of these three components change with age?
What will be an ideal response?
Heritability is the proportion of variation in IQ scores that is attributable to variation in heredity (50%).
Shared environment is the proportion of variation in IQ scores that is attributable to environmental factors shared in common (such as a common home and school environment) (25%).
Non-shared environment is the proportion of variation in IQ scores that is attributable to differences in the unique environments of children (25%).
Heritability increases with age and shared environment decreases.
Non-shared environment accounts for a small but equal share of variability across age.
