Cardon, Lon R.; And Others
Developmental Psychology, v28 n1 p64-73 Jan 1992
Yearly cognitive tests were administered to adoptive and nonadoptive siblings between one and seven years of age and identical and nonidentical twins between one and three years. Results indicated that genetic influences are a source of continuity and change in mental development, whereas shared and nonshared environmental effects contribute to continuity and change, respectively.
