Pioneering research has shown that infants are capable of perceptual discrimination and has provided some indication of the nature of the discrimination; that is, what stimuli are differentiable. Studies have demonstrated that significant effects exist, in stimulus-pair comparisons, for age of infant, speed of movement of stimulus during…

The purpose of this study was to investigate the development of organizational processes for both verbal and spatial stimulus materials within an information processing framework. Children in grades 2 and 4 and adults were tested for their ability to report letter strings reflecting various orders of approximation to English and various dot…

The purpose of this paper is to demonstrate that specific spatial and possibly temporal rates of change dominate early infants' looking, that these spatial and temporal events have meaningful and specific empirical correlates in neurophysiology as a function of age, and finally that neurophysiologically constrained models provide testable…

Children aged 6 through 9 made drawings of cubes and simple abstract designs, with or without looking at their hand. Copying errors and differences between the age groups were discussed in terms of visual realism (perspective drawing) compared with intellectual realism (structural essentials copied without a unified perspective view). (CTM)

Explores the effect of continuous training on tonal and auditory memory. Does so by comparing the auditory short-term memory skills of English and American children, ages five, six, and seven. (RKM)

Results supported Piaget's viewpoint that mental imagery and general symbolic functioning are dependent on the growth of intelligence with respect to the preadolescent period. (Author)

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 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)

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 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…

Investigated visual word recognition of first- through fifth-graders. Found that the "viewing position effect" typically seen in skilled readers and visual field asymmetries in recognizing individual letters in words emerged early at the end of the first year of reading instruction. Noted that findings support the view that basic reading…
