Attempts to determine what effect, if any, a color's hue or value has on the elementary school child's perception of apparent weight. (Author/RK)

This investigation with 122 college students, including 45 deaf students, found that neither deaf nor hearing students demonstrated a statistically significant advantage in accuracy or recall of nonverbal information about people in photographs. Deaf subjects, however, were more than twice as likely as hearing subjects to base their judgments upon…

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…

Compared the timecourse of inhibition of return (IOR) of young children to that of older children and adolescents in single and double cue procedures. Found no IOR in the young children unless a double cue was used, but for older groups, found IOR at all intervals with a double cue and the typical crossover pattern, with early facilitation…

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.…

Nonverbal IQs were greater than verbal IQs for children (ages 3-7) on the Stanford-Binet: IV (n=53). However, WISC-III verbal and nonverbal IQs were similar for older children, 6-15 years of age (n=63). Stanford-Binet: IV profiles were generally consistent for the low-IQ and high-IQ groups with high scores on visual matching tests. (Contains…

Investigated shifts of gaze to peripheral targets in full-term and very preterm infants with transient periventricular echogenicity, a type of short-term brain damage, between 6-26 weeks old. Found that differences between full- and preterm infants was small, but after 16 weeks, there were subtle differences between them as preterms took longer to…

A study involving 93 children (ages 10-12), 295 with poor reading skills, found many children with dyslexia and some garden-variety poor readers showed significant left neglect on the Clock Drawing Test. In poor readers with dyslexia, spatial construction deficits were observed like those of parents with acquired right-hemisphere lesions.…

Thirty students (ages 3-20) with profound mental retardation and 30 healthy, full-term infants (5-8 months) were shown 12 patterned stimuli, three times each. Both groups looked significantly longer at face patterns than other patterns. However, the students with mental retardation looked longer at black and white patterns than colored patterns,…

Described is a way to use knots to relate a three-dimensional object to a two-dimensional representation of the object. The results are used to produce an algorithm or rule to explain a general case. Included are examples, diagrams, procedures, and explanations. (KR)

This study assesses the validity of an interview questionnaire designed to predict performance by low-vision adults (N=41) on tasks of finding, detecting, scanning, and tracking. Subjects' ratings of difficulty with these tasks were compared to ratings of trained professionals. Results indicate self-report may be of some value in predicting…

This study showed that the Elementary Perceiver and Memorizer (EPAM) can explain letter recognition phenomena earlier simulated by the connectionist Interactive Activation Model of word perception. EAPM, a model of learning and recognition in the form of a computer program, has previously explained many aspects of learning and perception. (TJH)

Describes environments for concretely enacting multiplication and division. Discusses difficulties occurring when students use one of the concrete environments to model situations involving modified environments. (YP)

Investigates visual processing asymmetries in normal and dyslexic readers to determine whether differences between dyslexics and normals were due to structural hemispherical differences or to strategical processing differences. Results indicate dyslexics behave as normal readers if they are unable to predict whether the stimulus will be verbal or…

The study used 32 children (mean age 11 years) with moderate sensorineural hearing losses to examine whether Test of Auditory Comprehension of Language (TACL) scores were significantly affected by mode of presentation. No differences were found between auditory-only and auditory-visual modes of presentation. (Author/DB)
