Reviewed studies that used methods of brief lateral visual presentation of linguistic stimuli to investigate asymmetry of organization in the cerebral hemispheric functions of both normal and poor readers. Most studies failed to demonstrate that both groups approach the given tasks in the same way. (Author/DB)

Assesses the impact of the visual complexity of "Sesame Street" segments on preschoolers' visual attention, recall, and recognition. Results indicate that attention and learning are enhanced by (1) visually simple sets in terms of few objects on the screen and (2) low to moderate levels of screen activity. (PD)

Four experiments demonstrated that mental images are functionally equivalent to physical errors of movement in producing changes in visual-motor coordination, at both central and peripheral levels of the visual-motor system. Subjects observed or imagined pointing errors after pointing movements were completed. Imagery vividness ratings were also…

Earlier research with the lexical decision task led to the hypothesis that semantic context facilitates the encoding of words related to the context. Six experiments which employed different tasks (e.g., making a lexical decision) and different experimental paradigms (e.g., tachistoscopic exposures with masking stimuli) further investigated this…

First, third, and eighth graders performed four different orienting activities to different words. Under an incidental learning paradigm, the children's recognition was tested after the orienting activity. Age differences in recognition were absent, and the effect of the orienting activity responses on recognition supported depth of processing…

Results of perceptual tests administered to 50 retarded readers and 50 average readers in third grade indicated a significant difference between the two groups on visual sequential memory for letters. (CL)

This study sought to develop the picture-interpretation strategies of fourth-grade children by providing training in the use of such verbal guidelines as "Help yourself to all the given information." The program apparently helped the children produce more inferences, but did not enhance their skills in evaluating inferences. (Author/JEG)

A reaction time paradigm was used to investigate developmental differences in ability to rotate and compare imaginal representations. Subjects were 16 children from the third and fifth grades, and eight college students. (Author/MP)

Focuses on the differential representation of mental functions between the two human cerebral hemispheres. The manner in which right hemisphere function laterizes in childhood was studied in 98 five- to twelve-year-old children. (CM)

Separate experiments focusing on attention to multiple stimuli, psychological refractory period, and motor coordination demonstrated that emergent aspects of the whole situation must also be considered. Performance under divided attention reflected an interaction between resource limitation, single task processes, and emergent aspects of the whole…

Outlines a concentrated in-service visual training program which incorporates (1) perceptual effects of visual stimuli, (2) synthetic and natural stimuli, (3) non-verbal stimuli, (4) pictorial communication, (5) visual persuasion, and (6) creative visualization. (Author/CMV)

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)

Pigeons learned discrimination rapidly and responded differentially to pictures seen for the first time. The essential feature of a natural discrimination--which is the ability to cope with natural ranges of variation--was approached and earlier experimental results were extended using other classes of stimuli. (Author/RK)

Notes that, in Spanish, there is empirical support for the notion that, in visual word recognition, the syllables initially activate competing lexical candidates. Presents experiments intended to explore these inhibitory processes and discusses the applicability of the data to a dual-route model and the time course of syllabic processing. (55…

Discusses some of the theory underlying visual access tools for special collections, introduces a specific World Wide Web application using the technology, and indicates some of the potential of the tool for visual access to images as well as text documents. Appendices include texts of courses used for proximity calculations as well as NASA…
