Intraindividual variability (IIV) in cognitive speed, or moment-to-moment changes in ability, is a developmental phenomenon indicative of neurological integrity that increases gradually across adulthood. Past research has shown that IIV negatively covaries with cognitive performance, in which higher IIV at one occasion is associated with poorer…

The nonword repetition (NWR) test has been shown to be a good predictor of children's vocabulary size. NWR performance has been explained using phonological working memory, which is seen as a critical component in the learning of new words. However, no detailed specification of the link between phonological working memory and long-term memory…

Investigates cerebral asymmetries to study the perception of visually presented emotional and verbal material. Grade 1/2, Grade 4/5, and Grade 8 children reported on emotional facial expressions and on letters shown laterally and tachistoscopically. Findings indicate right hemisphere dominance for mediating visual emotional information from as…

The effect of verbal labeling in a serial position short term memory task was investigated. Forty female college students were given 16 trials each. Eight trials involved only central items which had to be recalled. The other eight trials involved both central and incidental items. Half of the subjects verbalized the names of the central items as…

Developmental patterns in the solution of verbal analogies, especially the recognition of higher-order analogical relations, were traced. The investigation sought to: (1) provide new developmental tests of a componential theory of analogical reasoning; (2) identify strategy changes during the transition from midchildhood (grade 3) to adulthood…

Analysis of 165 studies (representing the testing of 1,418,899 subjects) that reported data on gender differences in verbal ability indicated a slight female superiority in performance. The difference is so small that it appears that gender differences in verbal ability no longer exist. A major goal was also to define age trends in the pattern of…
