Intelligence Quotient Pattern over Age: Comparisons among Siblings and Parent-Child Pairs

Robert B. McCall 1

1 Department of Psychology, Fels Research Institute, Yellow Springs, Ohio 45387

Comparisons between sibling and parent-child pairs with unrelated control pairs matched for year of birth and parental education were made to determine the relative heritability of the general level of intelligence quotient as opposed to that of the sequential pattern of IQ change over age (3 to 12 years). There was greater similarity among related siblings relative to matched controls for general level than for pattern of IQ over age. Relationships between the IQ's of children and that of their parents as children were not consistent across age.
