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.,…

The mature visual system condenses complex scenes into simple summary statistics (e.g., average size, location, orientation, etc.). However, children, often perform poorly on perceptual averaging tasks. Children's difficulties are typically thought to represent the suboptimal implementation of an adult-like strategy. This paper examines another…

Atypical processing and integration of sensory inputs are hypothesized to play a role in unusual sensory reactions and social-cognitive deficits in autism spectrum disorder (ASD). Reports on the relationship between objective metrics of sensory processing and clinical symptoms, however, are surprisingly sparse. Here we examined the relationship…

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…

The aim of the present study was to compare the types of exploratory procedures employed by children when exploring bidimensional tactile patterns and correlate the use of these procedures with the children's shape drawing performance. 18 early blind children, 20 children with low vision and 24 age-matched blindfolded sighted children aged…

Using nationally representative samples of 45,964 two- to nine-year-old children and their primary caregivers in 17 developing countries, this study examined the relations between children's cognitive, language, sensory, and motor disabilities and caregivers' use of discipline and violence. Primary caregivers reported on their…

Sensory processing difficulties (SPD) are prevalent among children with ADHD. Yet, the question whether different SPD characterize children with different types of ADHD has not received enough attention in the literature. The current study characterized sensory processing difficulties (SPD) of children with different types of ADHD and explored the…

This study investigated the association between therapeutic riding (TR) and the social communication and sensory processing skills of 21 elementary students with autism attending TR as part of a school group. An interrupted treatment design was employed to determine whether children were able to maintain treatment effects following the removal of…

In a population-based sample of 112 nine-year old twin pairs, we investigated the association among total brain volume, gray matter and white matter volume, intelligence as assessed by the Raven IQ test, verbal comprehension, perceptual organization and perceptual speed as assessed by the Wechsler Intelligence Scale for Children-III. Phenotypic…

Used a multivariate approach and longitudinal design to examine the relationship of early perceptual and cognitive development in first grade, to school achievement in fourth grade. Results indicated variables used to predict achievement differed between the sexes, and sex as a predictor variable depended upon area of achievement studying.…

Children with congenital blindness are delayed in understanding other people's minds. The present study examined whether this delay was related to a more primitive form of inter-subjectivity by which infants draw correspondence between parental mirroring of the infant's display and proprioceptive sensations. Twenty children with congenital…

A study of differential brain hemisphere involvement in second language acquisition is reported. The study examined the idea that the right hemisphere is progressively more involved the later the second language is acquired. Various techniques for monitoring hemispheric functioning are described, especially the Evoked Potential (EP) technique. In…

The bibliography contains 75 annotations of empirical studies (1958-1974) on the psychomotor training and development of young handicapped children (1-19 years old). Studies are organized in two ways: alphabetically by author, and diagrammatically according to research thrust. The research thrusts (followed by the number of studies in each area)…
