Socioeconomic status (SES) is a well-known predictor of cognitive achievement and executive functioning, although the underlying cognitive mediating processes remain unclear. The authors analyze the association between different socioeconomic indicators and the executive functions (EF) of schoolchildren and the possible cognitive mediating factors…

Examined whether verbal IQ, performance IQ, or chronological age is a better predictor of verbal control of nonverbal behavior in four- and five-year-olds. (DP)

The general ("g") factor is the most general and relevant cognitive ability. This factor is considered to be one of the most important predictors of academic achievement and of many other socially relevant behavioral outcomes. In the last decades, many researchers have investigated the possible changes in the relevance of the…

Examines the relationship between performance on two measures of fluid intelligence, one measure of crystallized intelligence, and three Piagetian measures of intelligence. Subjects were 102 first- and second-grade students. (BD)

Forty college students were administered a self-rating scale for intelligence along with several actual ability measures, including the Concept Mastery Test and "breadth" and "depth" indices based on the Weschsler Adult Intelligence Scale Similarities subtest. (MS)

Analysis of the mental factors of seventh grade students indicates that numerical facility and perceptual speed are a single factor at this age level and that no purely verbal factor exists. Seven clearly differentiated factors are found for males and five for females. (Author/WY)

Most psychologists and educators assume that intelligence is a linear construct, meaning that smart people simply have more intelligence than their less gifted peers. Likewise, individuals with mental retardation are thought to have less intelligence. In contrast to this widely accepted belief, the authors posed an alternative hypothesis--that…

This study attempted to identify the factors of intelligence associated with the solution of a Piagetian task. Liquid conservation and 18 psychometric tests which included subtests from the WISC, ITPA, Raven Matrices, Primary Mental Abilities, and others were administered to 133 first- and second-grade boys and girls. (MS)

In a study of teacher expectations and behavior, teachers were told that certain children would bloom in creative ability. Eight months later the designated bloomers showed gains in creativity scores as well as in their IQ scores. (ST)

A classification of natal influences is proposed with a model of their operation. Natal influences affect maternal capacity, maternal load, and maternal efficiency. Since maternal load is increased in twin pregnancy, results of twin studies must be generalized with caution. The method of co-twin control is exemplified by examination of a small…

Mothers were asked to predict their children's responses to standardized intelligence test items. Negative correlation was expected between inaccurate maternal knowledge of children's ability and degree of children's psychological development. False maternal predictions correlated - .80 with correct children's responses. Nearly all of the…

Results suggested that when role taking is viewed as requiring a shift to less subjective views, different types of role-taking skills (communicative, spatial, relational, and cognitive) are moderately related. Results also indicated intellectual ability underlies these role-taking skills. (Author/DB)

Examines assumptions of the confluence model of the effects of family structure on children's intelligence. Subjects were 24 preschool children. Findings indicate that individual differences in intellectual ability are associated with the amount of time children spend in certain activities and with certain people. (Author/RH)

Study results showed that motor response inhibition varied as a function of age but not IQ; this pattern was reversed for cognitive inhibition. (DP)
