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…

How do teachers teach gifted students whose emotional age trails their chronological age? How can they integrate those students into their classes so that these students mature while not detracting from the learning of the other students? In this article, the author offers pieces of advice on teaching gifted students whose emotional ages trail…

The aim of this study was to compare the prosodic profiles of English- and Spanish-speaking children with Williams syndrome (WS), examining cross-linguistic differences. Two groups of children with WS, English and Spanish, of similar chronological and nonverbal mental age, were compared on performance in expressive and receptive prosodic tasks…

Aberrant attention is a core feature of fragile X syndrome (FXS), however, little is known regarding the developmental trajectory and underlying physiological processes of attention deficits in FXS. Atypical visual attention is an early emerging and robust indicator of autism in idiopathic (non-FXS) autism. Using a biobehavioral approach with gaze…

The present study examined narrative development in children and adolescents with Down syndrome longitudinally. Narratives were collected from 32 children and adolescents with Down syndrome three times over a 1-year period. Both micro- and macrolevel analyses were conducted. Significant growth over the 1-year period was seen in semantic complexity…

Pain coping is thought to be the most significant behavioural contribution to the adjustment to pain. Little is known about how those with intellectual and developmental disabilities (IDD) cope with pain. We describe parental reported coping styles and how coping relates to individual factors. Seventy-seven caregivers of children and adults with…

Language profiles of children with autistic disorder and intellectual disability (n = 36) were significantly different from the comparison groups of children with intellectual disability (n = 26) and typically developing children (n = 34). The group low-functioning children with autistic disorder obtained a higher mean score on expressive than on…

This study compared mothers and fathers' regulation with respect to 29 children with intellectual disability (ID) and 30 typically developing (TD) children, matched on their mental age (MA), as they solved eight tasks using physical materials and computers. Seven parents' regulatory strategies were coded as they supported their child's…

Recent studies indicate that children with intellectual disabilities have functional limitations primarily in the phonological loop of working memory (Baddeley, 1986). These findings are indicative of a specific structural deficit. Building on this research, the present study examines whether it is possible to identify specific phonological…

Inhibition of inappropriate responses allows to shape the motor behavior accordingly to the context in which a subject acts and is an essential executive function. Inhibition has been poorly investigated in Down Syndrome (DS) patients. We tested, using a countermanding task, the inhibitory control in a group of DS patients and in a group of…

The current study describes everyday executive function (EF) profiles in young children with Down syndrome. Caregivers of children with Down syndrome (n = 26; chronological ages = 4-10 years; mental ages = 2-4 years) completed the Behavior Rating Inventory of Executive Function-Preschool (BRIEF-P; G. A. Gioia, K. A. Espy, & P. K. Isquith, 2003), a…

Background: Recent studies have demonstrated that individuals with Down syndrome (DS) are poorer than controls in spatial-simultaneous tasks, but not in spatial-sequential tasks. To explain this finding, it has been suggested that the simultaneous visuo-spatial working memory deficit of individuals with DS could be due to the request for…

Background: There is little previous research examining whether measures of working memory are related to educational achievement in children with intellectual disabilities (ID). Methods: A battery of working memory and achievement measures was administered to 11- to 12-year-old children with ID; younger typically developing children of comparable…

In order to examine the roles of mental age, social interaction, and communication in self-representation abilities, typically-developing children were compared with children with Autism Spectrum Disorders. Typically-developing children (TD, n = 66) and children with Autism Spectrum Disorders (ASD, n = 20), including subgroups of autistic disorder…

This study presents a meta-analytic review of language and verbal short-term memory skills in children with Down syndrome. The study examines the profile of strengths and weaknesses in children with Down syndrome compared to typically developing children matched for nonverbal mental age. The findings show that children with Down syndrome have…
