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…

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…

The relationship of aptitude, strategy, and cognitive task performance is explored through the use of mathematical models of performance time. Models of strategy and strategy-shifting on a spatial visualization task were tested individually for 30 male high school and college subjects. For each of three successive task steps (encoding,…

Previous research on the nature of aptitude processes had ignored the important differences between speed and level of performance. However, investigations of the relationship between individual differences in speed and level suggest that speed of solving simple spatial tasks is largely independent of level attained on more complex spatial tasks.…

The purpose of this study was to explore the relationships of certain cognitive variables to problem-solving performance. Cognitive restructuring, spatial ability, reading comprehension, and mathmatical story problems tests presented in a regular verbiage, low verbiage, and drawn formats were given to students in grades three through seven.…

Strategic differences in spatial tasks are explained in terms of different cognitive coordinate systems that subjects adopt such as standard versus arbitrary, task-defined axes. A theoretical account of mental rotation of individuals of low and high spatial ability solving problems from psychometric tests is instantiated as computer simulation…

When 1,201 males and 1,145 females responded to a range of spatial questions, males significantly outperformed females on 25 of 72 occasions. On no occasion did females significantly outperform males. Wattanawaha's system for classifying spatial tasks was used to identify qualitative differences in performances of males and females.

Investigated the development of reorientation abilities in humans in contrast to other mammals. Findings support the domain specificity of human's core cognitive abilities, the conservation of cognitive abilities across related species and over the course of human development, and the developmental processes by which core abilities are extended to…

Studied children's transitive inference where representation of premises provided contradictory information depending on position of two elements in a A, B, C series. Eight-year olds did significantly better on the more complex problems than did six-year olds, suggesting the presence of a developmental sequence of algorithms that enable children…

Studied representation of text content and representation of the surface form of the text in two studies of native French speakers. Twenty-five subjects (aged 23-30) participated in Experiment 1, and 40 subjects (aged 23-30) participated in Experiment 2. Data confirm that readers retain the spatial location of words read. (Contains 18 references.)…

Used a variance-partitioning procedure to identify age-related and age-invariant components of verbal and spatial memory span in 6- to 12-year olds. Concluded that verbal and spatial short-term memory appear to rely on similar processes when serial recall is required and that development in span is closely tied to increases in processing speed.…

Discusses the factors that seem to be significant in the development of visualization skills, and examines gender differences in background and visualization ability for students enrolled in United States, German, and Polish technical universities. Findings indicate significant differences in spatial visualization ability between male and female…

Determined the effects of classroom music instruction featuring the keyboard on the spatial-temporal reasoning of 62 kindergartners assigned to keyboard or no music conditions. Found that the keyboard group scored significantly higher than the no music group on both spatial-temporal tasks after 4 months of lessons, a difference that was greater in…

Children diagnosed with Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) and Asperger Syndrome (AS) may be characterised by a similar perceptual focus on details as children with autistic disorder (AD). This was tested by analysing their performance in a visuoperceptual task [the Children's Embedded Figure Test (CEFT)] and a…
