Children increasingly resemble their parents in cognitive abilities from infancy through adolescence Results obtained from a 20-year longitudinal adoption study of 245 adopted children and their biological and adoptive parents, as well as 245 matched nonadoptive (control) parents and offspring, show that this increasing resemblance is due to genetic factors Adopted children resemble their adoptive parents slightly in early childhood but not at all in middle childhood or adolescence In contrast…

Multivariate Path Analysis of Specific Cognitive Abilities Data at 12 Years of Age in the Colorado Adoption Project
TLDR
Estimates of bivariate-heritability indicate that on average about half of the phenotypic correlations among the four specific cognitive ability measures are due to genetic effects, which would be interpreted as greater heritability by the parent–offspring design.
Social development from infancy to adolescence: longitudinal and concurrent factors in an adoption sample.
TLDR
Results showed that social development and temperament were stable over time and that both previous and current parental sensitivity were important in predicting social development in adolescence.
Cognitive Abilities in Childhood and Adolescence
General cognitive ability is associated with important life outcomes such as educational and occupational attainment, social mobility, and even health. The study of the behavioral genetics of
Maternal sensitivity, infant attachment, and temperament in early childhood predict adjustment in middle childhood: the case of adopted children and their biologically unrelated parents.
TLDR
It is concluded that even in adopted children, who are not biologically related to their adoptive parents, early mother-infant interactions and attachment relationships predict later socioemotional and cognitive development, beyond infant temperament and gender.
Differences in genetic and environmental influences on the human cerebral cortex associated with development during childhood and adolescence
TLDR
The observation that regions associated with complex cognitive processes such as language, tool use, and executive function are more heritable in adolescents than children is consistent with previous studies showing that IQ becomes increasingly heritable with maturity.
FAMILIES and economic mobility
• Traits in children like leadership, conscientiousness, and attitude explain a significant share of the variation in earnings and occupational status, but much less is understood about parents' role

Genetic influence on general mental ability increases between infancy and middle childhood
TLDR
The Colorado Adoption Project is the first large-scale longitudinal adoption study of behavioural development and provides conclusive evidence for increasing heritable variation of general mental ability, ranging from 9% at 1 year of age to 36% at 7 years.
The Louisville Twin Study: developmental synchronies in behavior.
TLDR
The overall results pointed to a strong developmental thrust in the growth of intelligence, which was principally guided by an intrinsic genetic ground plan, and Qualitative features of home and family did not add significantly to prediction of offspring IQ.

TLDR
Developmental change in twin similarity was examined with age contrasts in a meta-analysis of twin studies from 1967 through 1985 and indicated that there was a general tendency for some intraclass rs to decrease with age.
