The extent to which cognitive development and abilities are dependent on language remains controversial. In this study, the analogical reasoning skills of deaf and hard of hearing children are explored. Two groups of children (deaf and hard of hearing children with either cochlear implants or hearing aids and hearing children) completed tests of verbal and spatial analogical reasoning. Their vo...

In school settings, students are typically evaluated using group achievement tests, IQ scales, and college entrance exams that focus more on rote-verbal skills (e.g., vocabulary, mathematical facts) than on higher level executive functions (e.g., abstract thinking, problem solving). However, recent neuropsychological findings suggest that rote-knowledge skills and executive functions are diverg...

The purpose of this study was to assess the influence of verbal and visual cues on 28 nondysfunctional 3- and 4-year-old children's performance of in-hand manipulation skills. During the uncued version of the test (pretest), the children were presented with play activities known to elicit in-hand manipulation skills in young children but were given no cues for specific manipulative skill use. W...
