The cognitive determinants of number series completion performance were studied by presenting a systematic set of problems to adults and to children of high and average intelligence, grades 4 and 5. Pearson correlations between these problems and the number series on the Cognitive Abilities Test were .51, .78 and .43 for the average intelligence,…

Fifty-six children (ages 43 to 83 months) participated in an event conducted by two undergraduates dressed as clowns. Ten days later, interviews found metamemory ability, intellectual functioning, and temperament were helpful in determining a child's capacity to accurately recall information, although for the most part age was the best predictor.…

Students of high intellectual ability and their parents were tested on a battery of cognitive tests. Vernon's model of intelligence best fit results. A verbal-educational and a practical-spatial-mechanical factor explained most performance variance. Among children, age related to verbal but not spatial or mechanical abilities. (Author/RD)

The cognitive determinants of number analogy performance were studied by systematically manipulating the processing demands imposed by the items. To explore sources of developmental differences in analogical reasoning, subjects were included from two age levels, grades 4 and 5 and college. To allow the investigation of individual differences in…
