Both right-and left-handed normally developing 6-year-olds showed considerable evidence of bilateralization of hemispheric functions for spatial and verbal information processing; the slowly developing children (ages 5-9) exhibited unusual patterns of hemispheric specialization usually opposite those typically expected in children or adults.…

Reports that complex abstractions may be easily acquired by persons of less than 75 IQ if the method of presentation of the abstractions ensures maximum visibility of relevant details. (FL)

Twenty-four elementary school children ranging in age from 7 to 10 years identified tachistoscopically presented arrays varying in length and degree of orthographic constraint. (Author/MP)

The spread of encoding concept was tested visually by having subjects view pictures which varied in contour completeness. The hypothesis was supported that as contour completeness decreased, the amount of perceptual analysis and memory performance would increase. (Author/MH)

Young children (153 normal preschool and primary graders, 19 cerebral palsied 5 to 15 year olds, and 16 learning disabled 7 to 12 year olds) were given a test of immediate visual memory which required selection of a geometric design from among six alternatives, including a mirror image and a rotation. (CL)

Two methodological problems often arising in dyslexia research are considered. The first problem concerns the validity of experimental measures and the related problem of interpreting null results. The second problem involves the effects of sampling from a disabled population if the disorder under investigation has multiple unknown origins.…

Reports that when hearing-impaired children imitated nonsense words containing bilabial consonants, the rank order of correct responses and total choices was "b" (highest), "m," and "p" (lowest). The data are discussed in terms of auditory-visual perceptions of the hearing impaired and the order of the sounds in normal-hearing children. (Author/RL)

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)

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)

Suggestions for a modified indoor tennis game, for activities to develop body reference in young children, and for a drill to aid students with depth and space perception difficulties are presented. (LH)

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)

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)

Investigated the hypothesis that impulsive children differ from reflective children in their preferred strategy of information processing, based on extent of stimulus analysis. The experiments employed third, fourth and sixth graders and a variety of tasks including matching, grouping, recall, and concept attainment. (MS)
