An experimental test battery designed to measure several perceptual abilities was administered to 1,368 (51.8% male) paying clients of the Johnson O'Connor Research Foundation (JOCRF) in an effort to identify and measure three perceptual abilities: (1) flexibility of closure; (2) speed of closure; and (3) spatial scanning. Subjects, who ranged in…

Two experiments investigated preschoolers' acquisition of spatial words in Mandarin Chinese. In one experiment, 5 groups of 10 children at 34, 39, 46, 52, and 57 months were tested for comprehension and production of 14 pairs of Chinese spatial words. In the comprehension test the children were asked to point to pictures corresponding to the words…

Individual differences in verbal/analytic and nonverbal/holistic cognitive strategies were studied in relationship to performance levels in spatial tasks, sex and handedness. Analytic processes are described as sequential, resulting in decomposition of stimulus information, and holistic processes, as parallel, involving information synthesis.…

One of the important cognitive strategies individuals use when learning is to organize many bits of information into integrated patterns called chunks. To investigate the process of chunking spatial information, 32 college students integrated two cognitive maps either before or after an interfering task. The combined spatial layout formed either a…

The visual scanning of redundant and random spatial configurations of two-digit numbers was investigated in a target recognition task. The experimental technique involved a brief exposure of a probe (a two-digit number) at the center of the visual field, followed by a spatial pattern of 16 two-digit numbers which included the matching target in…

These studies aim to determine whether a partner's social role and extent of incorrectness were factors capable of interfering with the effects of social marking in spatial transformation tasks. Social marking refers to a condition in which correspondence exists between cognitive relations and some social relation. Experiment 1 assigned 68…

Although the distinction between verbal ability and spatial ability is fundamental in all models of human abilities, differences in the relative strengths of verbal and spatial abilities have failed to show consistent interactions with instructional treatments. This study investigated the hypothesis that spatial tests measure different abilities…

Individual difference variables that are potentially related to cognitive mapping skills were examined, and good and poor cognitive mappers were compared in terms of those variables. Good and poor cognitive mappers were identified on the basis of the accuracy of their spatial knowledge about their own community. Four categories of individual…

Researchers disagree not only about the existence or magnitude of sex-related differences in spatial perception, but also about the determinants of such differences. Training in three distinct spatial tasks was provided in an attempt to destablize individual and sex-related differences, while exploring the relative contributions of biological and…

Children ages 30 to 34 months, assessed at 18 months for security of attachment and categorized as anxious/avoidant, anxious/resistant, or securely attached, were observed exploring with their mothers in a large-scale laboratory space. (Quality of attachment was assessed by means of Ainsworth's standard strange-situation procedure.) After learning…

The comparative school readiness and cognitive ability of kindergarten children from lower-income schools (N=47) and from higher-income schools (N=71) were assessed using the Preschool Inventory and a battery of eight Piagetian tasks. The overall purpose of the study was to ascertain characteristics of the children's cognitive development as a…

Two experiments used the sentence-picture verification paradigm to study encoding and comparison processes with spatial information. Subjects decided whether a spatial description of a geometric figure matched a second figure. Three critical results demonstrated that task-specific variables could be the primary determinants of how subjects verify…

Gender differences in spatial ability in old age were examined and the effectiveness of cognitive training in reducing these differences was assessed. Age-related decline in the speed of problem solving, especially for men, was noted. Following training on mental rotation ability, there was no significant gender difference in spatial ability…

Examines spatial concepts required by young children for the understanding and manipulation of turn commands in Logo, and reviews the literature on children's Logo learning and the psychological-cognitive development of spatial concepts. Geometric concepts, alternative frames of reference, and the use of Turtle graphics are also discussed. (39…

The aim of this study was to gain a better understanding of the difficulties met by adults with lower levels of education on reading perspective drawings. Subjects were asked to describe verbally two perspective drawings of objects, then choose objects with defined spatial properties. Results indicated that success was an "all or…
