A telephone test battery to assess verbal, spatial, and memory ability and perceptual speed in adolescents was developed. Test materials were mailed to 212 adolescents (members of 54 adoptive and 52 nonadoptive sibling pairs). Results show that telephone testing can be satisfactorily used to assess specific cognitive abilities with less anxiety…

Compares gifted preschool boys and girls with both a CA (Chronological Age)-matched group and an MA (Mental Age)-matched group on their performance on a spatial projective task, a cognitive perspective-taking task, and an affective perspective-taking task. The data seem to support the hypothesis that psychometric brightness implies cognitive…

As part of a larger experiment to study computer-based methods of teaching Othello, 24 subjects who had never played the game were pretested with visual-spatial tests. After 16 games of Othello, subjects were tested on knowledge of the game. Correlations of pretest and posttest scores were computed. (LMO)

Discusses the value of building blocks for young children and describes developmental changes in their symbolic representation of space. Implications for activities to promote spatial representation are drawn. (AS)

When asked to construct, from memory, the spatial layout of a large scale area, kindergarteners and third graders placed objects more accurately when they had been presented a story connecting the objects than when no story had been presented. (RH)

Effects of inversion and reversal on children's word recognition performance were examined in relation to age, reading level, and word familiarity to determine whether retarded readers have greater facility with disoriented text than do normal readers. An inverse relationship between number and time ratios was found. (RH)

Examines mastery of spatial-transposition problems by 20-, 30-, and 42-month-old children. Subjects performed well on irrelevant transpositions of three cups. However, on relevant transpositions the correct cup was not selected until 42 months. Results suggest that children initially acquire search patterns on an experimental basis and gradually…

This book takes student inside the vast continent of Africa. The goal of these lessons is to provide young students with a look at contemporary Africa and to give them a feeling for the rich diversity of the many different nations of the continent. The lessons integrate language arts and geography, and some lessons include math. This book…

This collection of activities is designed to show how graphics display calculators can be used to explore pentominoes and tangrams. Activities include games and puzzles developing spatial relations. Teaching notes, solutions, and calculator instructions are included as are blackline masters. (MM)

A number of hypotheses about infants' delayed search accuracy have been based upon the notion that a location associated with repeated retrieval of an object attains privileged status. However, a test of performance in 12- and 15-month-old infants showed them to be indifferent to location. (Author/RH)

Tested the hypothesis that sex differences in patterns of cognitive ability could be accounted for by variation in identification with sex-role stereotypes. Males performed better on tests of spatial ability, and females performed better on tests of fluent production. The study's hypothesis, however, was not supported. (GC)

Examined memory for the lateral orientation of scenic pictures in young (N=112) and older (N=109) adults in two experiments under incidental or intentional learning conditions. Results suggested an age-related deficit in truly non-intentional encoding of orientation and pose a challenge for capacity theories of memory across the lifespan. (JAC)

In order to determine whether non-Western children would show a memory deficit for contextually organized spatial ability, the performances of 30 Mayan and 30 American nine-year-olds on reconstruction of an organized three-dimensional miniature scene were examined. (MP)

Eighty boys and 80 girls ages 9 to 10 from elementary schools in Naples, Italy completed a spatial span test and a spatial serial-learning task. Corsi's block-tapping test was used in each. Males performed better in both cases; their superior performance on the spatial serial-learning task was independent of their superiority in the spatial-span…

Describes how orientation maps can be incorporated into geographic slide lectures to keep students mindful of spatial relationships. (AM)
