Purpose: Early studies of perceptual learning of dysarthric speech, those summarized in Borrie, McAuliffe, and Liss (2012), yielded preliminary evidence that listeners could learn to better understand the speech of a person with dysarthria, revealing a potentially promising avenue for future intelligibility interventions. Since then, a…

The present study examined the reliability and validity of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) for use with deaf and hard-of-hearing (D/HOH) children. Psychologists (n = 10) provided data for 128 D/HOH children who were assessed with the WISC-IV as part of routine assessments. All the WISC-IV subtests (8) and…

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…

Background: Previous research with earlier versions of the WISC and WAIS has demonstrated that when administered to people who have intellectual disabilities, the WAIS produced higher IQ scores than the WISC. The aim of this study was to examine whether these differences still exist. A comparison of the Wechsler Adult Intelligence Scale-Third…

Children aged 2 and 3 years were exposed to a novel paradigm designed to train visual perception skills. The results indicate that children of this age could be trained to perform both percept deprivation and percept diagnosis tasks. Results are discussed with reference to engagement, a precursor to an adult-like understanding of perception.

The present study examined two key aspects of young children's ability to explain human behaviour in a mentalistic way. First, we explored desires that are of a level of difficulty comparable with that of false beliefs. For this purpose, the so-called "alternative desires" were created. Second, we examined how children's psychological…

Children with mental retardation have pronounced difficulties in using cognitive strategies and comprehending abstract concepts--among them, the concept of sequential time (Van-Handel, Swaab, De-Vries, & Jongmans, 2007). The perception of sequential time is generally tested by using scenarios presenting a continuum of actions. The goal of this…
