How long does it take to form a durable representation in visual working memory? Several theorists have proposed that this consolidation process is very slow. Here, we measured the time course of consolidation. Observers performed a change-detection task for colored squares, and shortly after the presentation of the first array, pattern masks were…

The influences of domain-specific meteorological knowledge and general visual-spatial abilities on the comprehension of simple weather maps were examined in a regression-based study involving a sample of participants with relatively low meteorological knowledge and in an experiment involving a contrast between samples of higher- and…

Young infants have repeatedly been shown to be slower than older infants to shift fixation from a midline stimulus to a peripheral stimulus. This is generally thought to reflect maturation of the neural substrates that mediate the disengagement of attention, but this developmental difference may also be attributable to young infants' slower…

This paper reviews recent literature in order to identify factors affecting student performance in introductory high school and college physics courses. An important factor identified was formation of cognitive structures such as formation of problem solving schemata. It was concluded that Piagetian concepts such as concrete and abstract reasoning…

The meta analysis reported in this paper considers the implications of combined correlational evidence for the nature of the relationships of mathematical and spatial skills, and for the possibility that spatial skill underlies gender differences in favor of males on mathematical tasks. In all, 136 studies reported in 116 articles and…

This study reports data concerning spatial abilities of professional art students. It is part of an ongoing collection of data on spatial abilities on the incoming freshman class at a large major private art school. The battery of eight tests has proven to be highly reliable and valid in previous studies with the specific population. Researchers…

Focusing on activity preferences at home rather than activity preferences in nursery school, this study examined the relationship between preschoolers' daily activities and spatial abilities. Parents of 52 preschoolers recorded their children's home activities for 7 days. Children were given three measures of spatial ability and one vocabulary…

Conservation ability, spatial motor ability, age, and gender were used as predictive variables in a study of 26 kindergarten children's computer programming ability. A preliminary pilot study with first graders had suggested that programming success was related to the ability to reverse thought processes. In both studies, children were taught to…

This newsletter theme issue contains four articles which focus on the development of normal and handicapped infants in various settings. "The Baby's World," by Lois Barclay Murphy and Colleen T. Small, emphasizes experiences of sensation and discovery in the first three years of life, noting the role of caregivers and the cultural context. "The…

Arguing that females need instruction in visuo-spatial skills before adolescence, when they begin to lag behind males in the development of these skills that are so strongly correlated with success in technical careers, this paper discusses the use of the three-dimensional and spherical graphics of ExperLOGO to develop spatial skills in students…

Work with patients with attentional deficits produced by posterior cerebral lesions has shown that such patients can identify words correctly even when they fail to report letters in nonwords contralateral to the lesion. Because of this, it has been assumed in cognitive neuropsychology that lesions do not produce new phenomena but instead provide…

Sixty-eight undergraduate college students served as subjects in a study that examined the effects of reader-generated map-like representations (spatial organizers) on subjects' delayed recall of a narrative. Of interest were the possible interactions between individual difference measures (verbal and spatial ability) and map generation on…

This study investigated the effects of solution-oriented and strategy-oriented feedback when using interactive computer-assisted instruction. The feedback confirmed problem solving strategies that were either similar to the learner's cognitive strategies (i.e., spatial strategies) or different from the learner's cognitive strategies (i.e.,…

This study was designed to determine item bias by sex on a test of spatial visualization administered to middle school students. Two chi square techniques were used to assess item bias: the Scheuneman C2 and the Camilli chi square. The direction of bias was indicated by assigning positive signs to the chi square components contributed by one group…

A study of eight adult chronic aphasic patients' comprehension of sentences and pictures in which comparisons of time and space were crucial was designed to assess A. R. Luria's approach to designing comprehension test tasks. The investigation required patients, with lesions of varying size and location, to determine whether a sentence expressing…
