Tasks in science, technology, engineering, and mathematics (STEM) are unusually varied because they target phenomena occurring in diverse domains and call upon a wide range of abilities to perform them. The fact that STEM tasks cover such a broad spectrum of abilities makes these fields uncharacteristically inclusive: Individuals with disabilities…

Children with autism have been shown to be less susceptible to Kanisza type contour illusions than children without autism (Happe, 1996). Other authors have suggested that this finding could be explained by the fact that participants with autism were required to make a potentially ambiguous verbal response which may have masked whether or not they…

It has been hypothesised that autism is an extreme version of the male brain, caused by high levels of prenatal testosterone (Baron-Cohen 1999). To test this proposal, associations were assessed between three visuo-spatial tasks and prenatal testosterone, indexed in second-to-fourth digit length ratios (2D:4D). The study included children with…

Students were classed as field dependent or field independent using Witkin's Rod and Frame and the Embedded Figures Test. In addition, each of the 269 grade 8 subjects performed Uznadze's set tasks. The number of trials required for excitation and extinction in the haptic and visual modality were noted. The field-dependent-independent groups,…

As one set of responses to the increasing demands of adequate yearly progress exerted by the No Child Left Behind Act, schools have been using professional learning communities as a tool to improve academic performance. The researcher conducted this descriptive quantitative study to query principals from 40 high- and 40 low-performing elementary…

Little is known about the impact of terrorism on children's cognitive functioning and school learning. The primary purpose of this study was to report on cognitive functioning among school-age children 20 months after a terrorist attack against their school. Participants included 203 directly and indirectly exposed children from Beslan and 100…

Language impairment is a hallmark of autism spectrum disorders (ASD). The origin of the deficit is poorly understood although deficiencies in auditory processing have been detected in both perception and cortical encoding of speech sounds. Little is known about the processing and transcription of speech sounds at earlier (brainstem) levels or…

This document reports on a study of how the eye and the hand become functionally coordinated during growth. A specific question researched is "How do children use their hands as perceptual tools for exploring objects in order to acquire information about them?" It was assumed that a pre-school child would have evolved a form of eye-hand…

In the design of visual simulation equipment for training systems, one key decision is the nature of the image storage medium to be used. One consideration in this complex issue is the adequacy of the depth cues which can be derived from imagery based on two- rather than three-dimensional sources. Although motion parallax is a relatively minor…

Compares monocular depth perception with binocular depth perception in five- to seven-month-old infants. Reaching preferences (dependent measure) observed in the monocular condition indicated sensitivity to monocular depth information. Binocular viewing resulted in a far more consistent tendency to reach for the nearer object. (Author)

Visual and auditory coding processes in learning-disabled students (SLDs, n=19) and control students (SCs, n=19) were examined. Analysis of decision latencies revealed that with initial task exposure, SLDs responded more slowly than SCs, but confusability patterns were similar. With practice, overall latencies became comparable, while…

Linguistic prominence is defined as words or syllables perceived auditorily as standing out from their environment. It is explored through changes in pitch, duration and loudness. In this study, phonetic realization and perception of prominence among lexical tones in Mandarin Chinese was investigated in two experiments. Experiment 1 explored…

Neuroimaging studies investigating the neural network of visuospatial processing have revealed a right hemisphere network of activation including inferior parietal lobe, dorsolateral prefrontal cortex, and extrastriate regions. Impaired visuospatial processing, indicated by the Judgment of Line Orientation (JLO), is commonly seen in individuals…

This study investigated whether children with high-functioning autism/Asperger's syndrome have a different spontaneous processing style than typically developing children, that is, a style where they prefer details over meaning. Participants were 25 children with autism spectrum disorders (ASD) and 25 typically developing children matched by age,…

The present study investigates the performance of persons with reading disabilities (PRD) on a variety of sequential visual-comparison tasks that have different working-memory requirements. In addition, mediating relationships between the sequential comparison process and attention and memory skills were looked for. Our findings suggest that PRD…
