CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Heritability of intelligence refers to: the amount of group variation in intelligence that can be attributed to genetics. The most widely used modern intelligence test was developed by: David Wechsler.

Detailed explanation-2: -The mean correlation of IQ scores between monozygotic twins was 0.86, between siblings 0.47, between half-siblings 0.31, and between cousins 0.15.

Detailed explanation-3: -An average IQ score is between 85 and 115. 68% of IQ scores fall within one standard deviation of the mean. That means that the majority of people have an IQ score between 85 and 115.

Detailed explanation-4: -Empirical evidence suggests that especially parental education, parental income, and maternal IQ are important predictors of intelligence. Parental education together with maternal IQ and the child’s sex were found to account for 24% of the variance in IQ at age 5 [6].
