The ability to efficiently allocate attention between two tasks (auditory and visual memory tasks) differing in payoff was investigated among three grade levels: second, fourth, and college. There were seven males and three females from each grade level. (MP)

It is suggested that reading is not a unitary process, but the acquisition of a succession of skills. Different retarded readers may break down at different stages in the acquisition of these. Each disability type may be associated with a particular type of deficiency in conceptual thinking. (Author/SJL)

Tested the hypotheses that errors of ommission would occur more frequently than errors of commission and errors would be related to stimulus complexity. A total of 48 children from grades 1 and 3 were given a memory task (involving visual and haptic memory) for recognition of random polygons. (MS)

Investigates the relationship between working memory (WM) capacity (particularly visuo-spatial working memory (VSWM)), the ability to mentally rotate three-dimensional objects, and mathematical skills. Explains that in experiment 1, VSWM was examined; and in experiment 2, contributions of other WM components to mathematical skills was examined.…

This study, with 53 Mexican-American infants, found that five predictors accounted for approximately 35 percent of the variance in receptive language at 12 and 22 months with average parental generation from Mexico (acculturation) and infant visual recognition memory accounting for 14 and 15 percent of the variance, respectively. No predictors…

The question regarding visual imagery and visual perception remain an open issue. Many studies have tried to understand if the two processes share the same mechanisms or if they are independent, using different neural substrates. Most research has been directed towards the need of activation of primary visual areas during imagery. Here we review…

Two experiments were conducted to investigate the effects of multimodal information on learning performance and judgment of learning (JOL). Experiment 1 examined the effects of representation type (word-only versus word-plus-picture) and presentation channel (visual-only versus visual-plus-auditory) on recall and immediate-JOL in fixed-rate…

There is some consensus in the literature regarding the cognitive profile of people with Asperger syndrome (AS). Findings to date suggest that a proportion of people with AS have higher verbal than performance IQ, a non-verbal learning disability (NVLD) and impairments in some aspects of executive function (EF). However, there are few published…

The factor-referenced kits developed by the Educational Testing Service (ETS) are assessed. With support from the National Science Foundation, the researcher surveyed the total range of research done over the past 65 years on the identification of cognitive abilities, principally through factor analysis. From a corpus of an estimated 2,000 data…

Synthesizing a diverse group of studies, author argues that reading disability is not a unitary phenomenon but can result from deficiencies in different psychological processes. Based on the points at which an individual's reading breaks down, she presents a fourfold classifications scheme capable of categorizing all poor readers. (Editor/RK)

Determines whether early hemispheric differences exist in tactual processing by testing infants and preschoolers on six cross-modal tasks. Results are the first to demonstrate a left-hand superiority for information processing in children as young as two years. (Author/AS)

Presents six diagrams that describe what happens when a text is read. (HOD)

Test Battery was designed to explore the auditory and the visual perceptual processing abilities of children from five through eight. (Authors)
