Ninety-three children (ages 10-12) were compared on phonological and visuospatial abilities. Children with a reading disability performed worse than nondisabled children on many visual and eye movement tasks. Sixty-eight percent of the variance in reading ability could be predicted by combining visual and phonological scores in a multiple…

A study was conducted to determine the effects of age, verbal ability, education, reading habits, and recall strategies on prose recall among adults. Subjects were 422 adults in three age groups--young (18-28 years), middle (40-54), and older (62-80). They were asked to read and recall in writing two 388-word prose passages and to answer questions…

Describes a study designed to determine if college students' success in writing computer programs is related to level of cognitive development as described by Piaget, verbal ability, and mathematics reasoning. Regression analysis showed that level of cognitive development, when combined with verbal reasoning, is linearly predictive of programming…

Discusses relation between verbal ability and metamemory and how these two factors relate to the later recallability of material. A study is described that separated 32 children into high and average verbal ability groups, administered a metamemorial questionnaire, and tested recall one week later. (Author/LRW)

Assesses 180 college students at three ages (17-23, 37-43, and 61-80) to examine the relative availability of Piagetian formal reasoning concepts; the relationship of these formal reasoning performances to Horn and Cattell's psychometric theory of general fluid and crystallized intelligence; and developmental patterns among standardized…

This paper addresses the problem of heterogeneity of samples of learning disabled (LD) children by comparing five different systems for identifying homogeneous subgroups in terms of their ability to predict longitudinal reading and mathematics scores. One hundred and sixty LD children served as subjects. Three of the five subgrouping systems were…
