Twelve elementary children talented in music and 12 talented in fine arts were matched with controls and given tests of personality, intelligence, verbal fluency, and an interest questionnaire. Despite little difference in general intelligence or reported development for the two groups, differences were found in self-confidence and home…

Investigation combined two heretofore unconnected research areas: the newly structured operation of divergent thinking and the older domain of family resemblances. (Author)

The differential impact of birth order and IQ on sibling roles were examined with particular interest focused on achievement outcomes. Subjects were a stratified sample of 37 pairs of near-in-age siblings, all within the normal range in personality and IQ, but differing significantly in scores on the Slosson IQ Test. Results indicate that when the…

The challenge of education is to extend the work of education from a classroom perspective which focuses on the child's learning academic subjects in the classroom with a professional educator to a life-time and life-space perspective which extends from birth onward. (Author)

Very close age spacing was an obstacle to high academic performance for later borns. In family relations and self-esteem, first borns scored better and performed in school as well as their potentially much more able younger siblings, regardless of age spacing. (Author)

Ronald C. Johnson argued that if early environmental stimulation or deprivation has a significant effect on intellectual ability, then individuals who are genetically identical and who are exposed to a common early environment should resemble one another more closely in IQ than similar individuals who have not shared a common environment. Johnson…

Research from the late 1960's to 1974 reveals that early sex role socialization affects the intellectual achievement and career choices of women. Whereas preschool girls test as well or somewhat better than boys on various intelligence measures, high school boys test higher in general intelligence, and number, spatial, and analytic ability. One…

Research on sibling influence on intellectual ability has shown that academic ability and achievement decrease as family size increases and as spacing between siblings decreases. Research also suggests a relationship between sex of subject and of sibling, and age differences in the effects of birth order and sibling sex. (JAC)

Support for the confluence model of intellectual development has come from analyses of family size-birth order means of large aggregate data sets. Analyses of individual scores do not substantiate the confluence model, as explained variance is markedly reduced. The study of family interaction variables utilizing longitudinal data is recommended.…

Relationships between six home environment measures, achievement and intelligence tests were examined by stepwise multiple regression analyses for a sample of 60 eight-year old children. Home variables were most successful in predicting achievement test scores, less successful regarding culture-dependent intelligence test scores, and least…

In this study, the relationship between a refined measure of the learning environment of the home and the levels and profiles of a set of mental ability scores of children from five Canadian ethnic groups was examined. Significant group differences persisted in the verbal, number, and reasoning scores. (Author/JMB)

A study of 54 Salvadoran children (age 12), born in the Salvadoran Civil War, found the personal/social impact of the war was more important than family togetherness or war intensity in determining the mental health of the children. Children's intelligence was highly related to surviving with greater mental health. (Author/CR)

According to confluence theory, a child is helped or hindered in intellectual development according to the average absolute intelligence (mental age) in the family when the child is born. An analysis of test scores, family information, and socioeconomic data of 36,000 college applicants in Colombia failed to support this theory. (Author/CP)
