Critiqued are five reviews of research puporting to examine the effectiveness of perceptual training in the improvement of reading. (DB)

Dot patterns varying in type of symmetry (double, vertical and horizontal symmetry, and asymmetry) were presented tachistoscopically for 200 msec, followed by a patterned mask, to 16 subjects in each grade level: kindergarten, second, and fourth-grade. (Author/JH)

Ethnoscience studies, and studies of color vocabulary in particular, have firmly established that to understand the full range of meaning of a word in any language, each new language must be approached on its own terms, without a priori theories of semantic universals. It has been shown that color words in fact encode a great deal of…

Examines the effectiveness of Frostig-Horne and Kephart-Getman techniques and materials in developing the perceptual and motor skills of young children. (TO)

Reports the effects of exposing both kindergarten and elementary school children to high and low speed motion pictures on children's estimation of time. Concluded the children's judgment is dependent upon their chronological ages and daily experiences of visual perception. (CC)

This article offers three listings of signs and symptoms useful in detection of learning and perceptual deficiencies. The first list presents symptoms of the learning-disabled child; the second gives specific visual perceptual deficits (poor discrimination, figure-ground problems, reversals, etc.); and the third gives auditory perceptual deficits…

Discusses ten elements of visual or photographic language using examples from a photographer's handling of an assignment to photograph an Alice Cooper concert. (TO)

The present study was designed to clarify issues concerning the development of the relative capabilities of modal systems when information acquisition is equated for the modalities by sequential presentation. (Author)

While the Bedouin children's perceptual exploration might be considered less mature in some ways related to reading, this was not the case with other aspects of perceptual exploration. (DM)

A discussion of the effect of background color on the legibility of projected printed messages on transparencies. (Author)

Two groups of 15 boys (mean age 8 years, mean IQ 100), both presenting difficulties in academic achievement, but one with and one without visuomotor impairments, were assessed to determine whether poor drawing ability was related to perceptual or motor disorders. (Author)

A study was conducted to determine the relationship of visualization abilities to achievement in chemistry. Two freshmen and one senior level class of chemistry majors were included. Two visualization tests and a chemistry examination at the end of the semester were conducted. A stronger relationship was reported between senior chemistry status…

A level prediction task, in the context of Piaget's conservation-of-liquid problem, was used to analyze the regularities of incompetence'' in the nonconserving or noncompensating child. (Author)
