“…Model fitting to the data yielded a heritability estimate of .56, an environmental transmission value of .01, an assortative mating value of .21, and a genotype-environment correlation of .01. A very similar trend, of adopted children becoming more similar to their biological than their adoptive parents over time, was reported by Honzik (1957). Boomsma et al (1999) have recently published estimates of heritability and shared environmental influence for IQ by age (5, 7, 10, 16, 18, 27 years of age) from a sample of Dutch twins.…”

Psychological researchers typically distinguish five major domains of individual differences in human behavior: cognitive abilities, personality, social attitudes, psychological interests, and psychopathology (Lubinski, 2000). In this article we: discuss a number of methodological errors commonly found in research on human individual differences; introduce a broad framework for interpreting findings from contemporary behavioral genetic studies; briefly outline the basic quantitative methods used in human behavioral genetic research; review the major criticisms of behavior genetic designs, with particular emphasis on the twin and adoption methods; describe the major or dominant theoretical scheme in each domain; and review behavioral genetic findings in all five domains. We conclude that there is now strong evidence that virtually all individual psychological differences, when reliably measured, are moderately to substantially heritable.

“…Sixth, the pattern of correlations within ages between standardized mental test performance and both general indices of intellectual environment and genetic circumstances are nearly zero during the first 18 months, rise rapidly thereafter until ages 5 or 6 (Bayley, 1954;Honzik, 1957), and then approach asymptote. Heritabilities for school-age and adult IQs are variously (and arguably) estimated to average .50 to .70.…”

“…Comparing Skodak and Skeels' results (1949) with correlations of children reared by their own parents, Honzik (1957) reported that the latter correlations ranged from .2 to .4, and increased steadily after age two. These correlations were based on various IQ tests given to the children compared to the number of years of education of the parents.…”

An Investigation of Similarities in Parent‐child Test Scores for Evidence of Hereditary Components

The general hypothesis of this study states that certain psychological traits which have their scores distributed continuously may actually have an underlying genetic dichotomy which is masked by various other effects. To be more precise, three specific hypotheses state for each variable that: (1) there is a similarity between parents and their children unexplained by similarity between the parents; (2) this similarity may be explained by hereditary components, and (3) these hereditary components are of the discrete or segregated type of inheritance. The population, consisting of 104 fathers and mothers and their teenage sons or daughters, was given eight psychological tests: Symbol Comparison, Word Association, Mental Arithmetic, Pitch Discrimination, Letter Concepts, Spelling, Identical Blocks, and English Vocabulary. Self‐reports of height and weight were also obtained. These data were analyzed both by correlational methods and dichotomic analysis. The latter is a new method designed for this study. Parent‐child correlations have previously been inadequate for investigating the presence of hereditary components in mental tests, because it is impossible to assess the degree to which the correlations are due to environmental effects. However, the transmission of a trait determined by a gene located on the X chromosome results in a unique pattern of family correlation coefficients.
