Background: Individuals with intellectual disabilities (ID) show difficulties with everyday planning. A tablet-based training program for everyday planning may be a suitable intervention, but its feasibility must be evaluated. This study evaluated how behavior changes during training and if individuals with ID can use technology by themselves.…

General cognitive and specific number abilities that underlay arithmetic performance have been heavily investigated among typically developing students; however, the inquiry has rarely been applied to students with mild intellectual disability (MID). We examined whether domain-general cognitive abilities (i.e. working memory, processing speed, and…

Working memory (WM) impairments might amplify behavioural difference in genetic syndromes. Murine models of Rubinstein-Taybi syndrome (RTS) evidence memory impairments but there is limited research on memory in RTS. Individuals with RTS and typically developing children completed WM tasks, with participants with RTS completing an IQ assessment and…

Mathematics is an important aspect of daily life. Basic numeracy skills are needed to accomplish everyday tasks. However, research regarding the relationship between cognitive ability, mental age, and basic numeracy skills for children with intellectual disability (ID) is scarce. This research study investigated the correlation between…

Previous research into face processing in autism spectrum disorder (ASD) has revealed atypical biases toward particular facial information during identity recognition. Specifically, a focus on features (or high spatial frequencies [HSFs]) has been reported for both face and nonface processing in ASD. The current study investigated the development…

The autistic impairments in emotional and social competence, imagination and generating ideas predict qualitative differences in expressive drawings by children with autism beyond that accounted by any general learning difficulties. In a sample of 60 5-19-year-olds, happy and sad drawings were requested from 15 participants with non-savant autism…

Background: Although there is growing awareness about the potential for people with Down syndrome (DS) to become literate, we know little about the characteristics of handwriting within this population. Methods: Thirty-three participants took part in this experiment. Eleven adults with DS and 22 typically developing individuals (11 children…

This study aimed to clarify factors related to difficulties in responding to "yes/no" questions (Y/N-Qs) among 52 children with autism spectrum disorder (ASD), 41 boys and 11 girls aged between 3:5-16:0 years. Participants completed the Tanaka-Binet Intelligence Scale V, the Picture Vocabulary Test: Revised (PVT-R), and the Pervasive…

Research has shown that verbal short-term memory span is shorter in individuals with Down syndrome than in typically developing individuals of equivalent mental age, but little attention has been given to variations within or across groups. Differences in the environment and in particular educational experiences may play a part in the relative…

To determine maternal stress and child variables predicting maternal stress, 104 mothers of children with autism spectrum disorder (ASD) and intellectual disability (ID) completed the Dutch version of the Parental Stress Index (PSI; De Brock, Vermulst, Gerris, & Abidin, 1992) every six months over a period of two years. The level of maternal…

The study aimed at exploring the effectiveness of cognitive intervention with the new "Instrumental Enrichment Basic" program (IE-basic), based on Feuerstein's theory of structural cognitive modifiability that contends that a child's cognitive functioning can be significantly modified through mediated learning intervention. The IE-basic…

Background: It is generally assumed that children with Down syndrome (DS) present a deficit in lexical production relative to their cognitive abilities. However, the literature on this topic has recently shown several contradictory results. In addition, most studies only consider vocabulary production in its vocal modality. However it is also…

Background: Effective literacy skills are crucial in supporting communication for children with severe speech and physical impairments (SSPI). Reading and spelling difficulties are reported to be over-represented in this group, even where language and cognitive skills are age appropriate. Aims: To compare the performance of children with SSPI on a…

This study investigates the syntactic abilities of ten individuals with Williams syndrome (WS) (mean chronological age: 8;9 years; mean mental age: 4;8 years) and Down's syndrome (DS) (mean chronological age: 8;7 years; mean mental age: 4;6 years), matched individually on chronological age, mental age and performance IQ. The syntactic components…

Research was undertaken to examine the level of support and general attitudes towards multi-level selective classes for gifted students amongst the staff and parents of an independent (non-government) boys' Preparatory school, located in Adelaide, South Australia. Questionnaires were sent to all parents and staff in the Preparatory school and…
