The integrated use of spatial and temporal information seems to support the separation of two sensory streams. The present study tested whether this facilitation depends on the encoding of sensory stimuli in externally anchored spatial coordinate systems. Fifty-nine children between 5 and 12 years as well as 12 young adults performed a crossmodal…

The mirror neuron system (MNS) is a trimodal system composed of neuronal populations that respond to motor, visual, and auditory stimulation, such as when an action is performed, observed, heard or read about. In humans, the MNS has been identified using neuroimaging techniques (such as fMRI and mu suppression in the EEG). It reflects an…

Visual learning enhances cognitive understanding of abstract concepts. Perception of such ideas as causality is enriched by visual examples. Perceiving should not be separated from thinking. (SK)

Rorschach protocols of both black and white children from 7 to 14 years of age, who had been evaluated at a child guidance clinic, were rescored with respect to developmental level of perceptual integration. It was found that black children had higher perceptual-integration scores in comparison to their white counterparts. (Author)

Psychometric test and the Uzgiris-Hunt Scale I (the Development of Visual Pursuit and the Permanence of Objects) were administered to mentally retarded preschoolers (N=105), school aged children (N=35), and adolescents (N=8), all functioning in the sensorimotor stage of development. Performances for each group are reported, and parent reactions…

Describes an empirical study that examined the impact of being carried on a parent's back on a child's visual integration pathways. Draws on a previous study (Pretorius et al.) postulating that this cultural behavior could have a negative impact as it prevents the child from crawling adequately or enough during the sensorimotor stage.

The paper reviews research trends and findings on the development of personality in deaf individuals. The first section, "Adolescent and Adult Deaf Personalities," focuses on studies in the psychological literature that tend to promulgate stereotypical views of deaf people by reflecting researcher bias rather than researcher findings.…

This final report reviews the second phase of a life-span study of boys with fragile X syndrome (FSX), the most common known inherited cause of mental retardation. Males with the syndrome are more severely affected than females and in males, delays are usually evident in all the developmental domains, although cognitive and communication skills…
