This study examined automatic processing of perceptual stimuli (auditory, visual, auditory-visual) and of linguistic units (morphological rules, grammatical structures, and syntactical control). Sixty average (85-115 IQ), Caucasian, middle class, eight-year-old boys were selected from La Habra School District second grades. The testing instruments…

Investigates developmental changes in the accuracy of aimed movements made to an illuminated target lamp by children between the ages of 1.5 and 8 years. Shows accuracy decreased with decreasing availability of visual information and improved with age under all conditions. (HOD)

Three studies explore the development of discrimination and memory for symmetry in preschoolers four to six years of age. Issues addressed include the young child's ability to discriminate and reproduce symmetry, and the effects of pattern orientation and complexity on the young child's symmetry discrimination and reproduction. Results indicate…

The reaching behavior of 12 infants in the presence of solid objects and pictures of objects placed within and beyond possible contact distance was videotaped in three sessions at 15, 19, and 24 weeks of age. (Author/MS)

The relation between perceptual organization and categorization processes in 3- and 4-month-olds was explored. The question was whether an invariant part abstracted during category learning could interfere with Gestalt organizational processes. A 2003 study by Quinn and Schyns had reported that an initial category familiarization experience in…

Early intervention approaches for facilitating motor development in infants and children with Down syndrome have traditionally emphasised the acquisition of motor milestones. As increasing evidence suggests that motor milestones have limited predictive power for long-term motor outcomes, researchers have shifted their focus to understanding the…

THE THEORY OF VISIBLE DISPLAYS IMPLIES A CONNECTION BETWEEN THE DEVELOPMENT OF PERCEPTION IN THE CHILD AND THE DEVELOPMENT OF HIS CAPACITY TO MAKE THINGS THAT STIMULATE PERCEPTION. TO VERIFY THIS, TWO STUDIES ON THE FUNDAMENTAL GRAPHIC ACT AMONG YOUNG CHILDREN CONSIDERED MOTIVATING FACTORS LIKE THE PLEASURE OF MOVING, KINESTHESIS, ACTIVITY DRIVE,…

The main purpose of this study was to investigate whether children's perceptual comprehension of symmetrical numerical displays was greater than their comprehension of asymmetrical numerical displays. Effects of sex, age and socioeconomic status were looked at. Seventy-three kindergarten and first grade children participated in the study.…

Beginning with a survey of work previously done on the subject, this study attempts to learn more about how, and to what extent, children benefit from pictorial illustrations, with a view to improving instructional materials. Three areas were investigated with experiments using children from nursery schools and kindergarten to sixth grade. The…

Three experiments obtained same-different judgments from children and adults to trace normal development of local and global processing of hierarchical visual forms. Findings indicated that reaction time was faster on global trials than local trials; bias was stronger in children and diminished to adult levels between ages 10 and 14. Reaction time…

Examined, over a 10-year span, continuity in individual differences in cross-modal transfer to visually recognized shapes that had previously been felt but not seen. Found that cross-modal performance showed a left-hand advantage at 11 years. Cross-age correlations were significant when tactual exploration at 11 years was done with the left hand.…

INFANT SCRIBBLING ACTIVITY IS NOT SIMPLY PLAY. IT CONTRIBUTES TO THE DEVELOPMENT OF VISUAL ATTENTION AND PERCEPTION. YET, SCRIBBLING, UNLIKE WRITING IN THE COMMUNICATION SENSE, IS NOT MOTIVATED BY THE DESIRE TO INFORM, NOR TO SET DOWN THOUGHTS AND FEELINGS. THE EXPERIMENTAL HYPOTHESIS OF THIS STUDY WAS THAT THE MOTIVATIONS FOR SCRIBBLING ARE (1)…

Fixation time, smiling, vocalization, and fret/cry were recorded to obtain a complete picture of infants' responses to facial stimuli over the first year of life. Four stimuli were presented to 120 infants. Results of fixation data indicate that (1) there is a marked decrease in fixation toward facial stimuli within the first year, (2) at all ages…

This research investigated temporal ordering acuity in children, or the ability to perceive the first of an ordered pair of lights, or of a combined light and tone, when the interstimulus time interval within each pair became increasingly short in duration. Two group-related comparisons were made: (1) differences between slow-maturing and average…

This study investigated the relationship between intramodal and intermodal information processing and performance on traditional age appropriate tests of spatial and perceptual-motor abilities. The ability of 65 normal kindergarten, first grade and second grade children to match to either a tactile or a visual standard was assessed with a modified…
