Detailed explanation-1: -As adopted children grow older, their intelligence scores become more similar to those of their biological parents than to those of their adoptive parents. Recent research findings support a “Mozart effect", this is, that having infants listen to classical music boosts their cognitive ability.
Detailed explanation-2: -As adopted children get older, their intelligence test scores tend to become: More like their biological parents as compared to their adoptive parents. Feng et al.
Detailed explanation-3: -The intelligence scores of adopted children are more similar to those of their adoptive parents than their biological parents. Most psychologists agree that intelligence is mainly determined by heredity. The Stanford-Binet test and the WAIS scales are periodically re-standardized.
Detailed explanation-4: -The first set of more than 400 pairs of full male siblings revealed that those who had been adopted had an average IQ score of nearly 97. Those who were raised by their biological parents had an average IQ of 92.
Detailed explanation-5: –Estimates of the heritability of intelligence (extent to which intelligence test score variation can be attributed to genetic variation) range from 50 to 80 percent.-The most genetically similar people have the most similar intelligence scores.
