Purpose: Differences in communication development impact long-term outcomes of children with autism. Previous research has identified factors associated with communication in children with autism, but much of the variance in communication skill remains unexplained. It has been proposed that early differences in sensory responsiveness (i.e.,…

More than a century ago, Galton and Spearman suggested that there was a functional relationship between sensory discrimination ability and intelligence. Studies have since been able to confirm a close relationship between general discrimination ability (GDA) and IQ. The aim of the present study was to assess whether this strong relationship…

In human adults, visual dominance emerges in several multisensory tasks. In children, auditory dominance has been reported up to 4 years of age. To establish when sensory dominance changes during development, 41 children (6-7, 9-10, and 11-12 years) were tested on the Colavita task (Experiment 1) and 32 children (6-7, 9-10, and 11-12 years) were…

Four- and seven-year olds were asked to make and explain predictions about their abilities to solve perceptual problems, perform the tasks, and explain their success or failure. Results indicated that young children have some clear-cut knowledge, and misconceptions, about their senses. Between four and seven years, children become increasingly…

Describes two experiments that examined whether the amplitude of the human eyeblink by a mild tap between the eyebrows can be increased if a brief tone is presented simultaneously with the tap and how these effects change from newborn infants to adults. (HOD)

This paper reports on the development and validation of an instrument for recording haptic exploratory behavior through detailed examination of exploratory search strategies of young children. Individual differences within age level were investigated, as well as the extent to which information processing capabilities for haptic perception are…

This experiment compared retarded and normal subjects at different developmental levels on visual (V) and haptic (H) matching tasks. Systematic observations of variables known to have developmentally linked effects on accuracy, including stimulus complexity and haptic exploratory search style, were made. Seventeen mentally retarded subjects, with…

This document is an English-language abstract (approximately 1,500 words) of a three-part volume on the psychology of child personality development. In part one, the author shows that psychology is one of the most important scientific disciplines on which education is based, particularly because of its contribution to the scientific planning of…

Discusses changes occurring in two-, four-, and six-month-old infants' visual attention span, through a series of experiments examining their ability to orient to peripheral visual stimuli. The results obtained were consistent with the hypothesis that infants get faster with age in shifting attention to a spatial location. (AA)
