Courbois, Yannick; Farran, Emily K.; Lemahieu, Axelle; Blades, Mark; Mengue-Topio, Hursula; Sockeel, Pascal – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
The aim of this study was to assess wayfinding abilities in individuals with Down syndrome (DS). The ability to learn routes though a virtual environment (VE) and to make a novel shortcut between two locations was assessed in individuals with DS (N = 10) and control participants individually matched on mental age (MA) or chronological age (CA).…

Limoges, Elyse; Bolduc, Christianne; Berthiaume, Claude; Mottron, Laurent; Godbout, Roger – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
Poor sleep is a common feature in autism even though patients themselves do not necessarily complain. The impact of poor sleep on daytime cognitive functioning in autism is not well-known and we therefore investigated whether sleep in autism correlates with daytime cognitive performance. A battery of non-verbal tasks was administered, in the…

Carretti, Barbara; Lanfranchi, Silvia; Mammarella, Irene C. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
Earlier research showed that visuospatial working memory (VSWM) is better preserved in Down syndrome (DS) than verbal WM. Some differences emerged, however, when VSWM performance was broken down into its various components, and more recent studies revealed that the spatial-simultaneous component of VSWM is more impaired than the spatial-sequential…

Hsu, Ching-Fen – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
Previous studies have shown that deficiencies in visuospatial perception and semantic processing in people with Williams syndrome (WS) are due to deficient central cohesiveness. Unlike previous studies that used abstract stimuli, this study used pictures to determine the relative ability of people with WS to integrate contextual information with…

Vakil, Eli; Lifshitz-Zehavi, Hefziba – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
Raven matrices are used for assessing fluid intelligence and the intellectual level of groups with low intelligence. Our study addresses qualitative analysis of information processing in Raven matrices performance among individuals with intellectual disability with that of their typically developed (TD) counterparts. Twenty-three adults with…

Vlachos, Filippos; Andreou, Eleni; Delliou, Afroditi – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
The present study examined the link between brain hemisphericity and dyslexia in secondary school students, using the Preference Test (PT), a widely used self-report index of preferred hemisphere thinking styles. The hypothesis was that differences would be revealed between the dyslexic group and their peers in hemispheric preference. A total of…

Wang, Li-Chih; Tasi, Hung-Ju; Yang, Hsien-Ming – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
The present study presents a comparison of the cognitive inhibition abilities of dyslexic, dyscalculic, and control students. The participants were 45 dyslexic students, 45 dyscalculic students, and 45 age-, gender-, and IQ-matched control students. The major evaluation tools included six cognitive inhibition tasks which were restructured during…

Caillies, Stephanie; Hody, Anais; Calmus, Arnaud – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
The main goal of the present study was to characterise the pragmatic abilities of French children with cerebral palsy through their understanding of irony and other people's mental states. We predicted that children with cerebral palsy would have difficulty understanding false-belief and ironic remarks, due to the executive dysfunction that…

Debrabant, Julie; Gheysen, Freja; Caeyenberghs, Karen; Van Waelvelde, Hilde; Vingerhoets, Guy – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
A dysfunction in predictive motor timing is put forward to underlie DCD-related motor problems. Predictive timing allows for the pre-selection of motor programmes (except "program" in computers) in order to decrease processing load and facilitate reactions. Using functional magnetic resonance imaging (fMRI), this study investigated the neural…

Wuang, Yee-Pay; Su, Chwen-Yng; Su, Jui-Hsing – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The primary purpose of this study was to investigate and compare the executive functions measured by the Wisconsin Card Sorting Test (WCST) between children with developmental coordination disorder (DCD) and age-matched normal controls. A second purpose was to examine the relations between executive functions and school functions in DCD children.…

Derlich, Malgorzata; Krecisz, Krzysztof; Kuczynski, Michal – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
To elucidate the mechanisms responsible for deteriorated postural control in children with hearing deficit (CwHD), we measured center-of-pressure (COP) variability, mean velocity and entropy in bipedal quiet stance (feet together) with or without the concurrent cognitive task (reaction to visual stimulus) on hard or foam surface in 29 CwHD and a…

Vakil, Eli; Lifshitz, Hefziba; Tzuriel, David; Weiss, Izhak; Arzuoan, Yossi – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Eighteen adults with intellectual disability (ID) and 20 children with typical development (TD) matched for cognitive level, participated in this study. Participants solved perceptual and conceptual analogies (from the Conceptual and Perceptual Analogical Modifiability Test-CPAM) while having their eye movements monitored. As predicted, the…

Danielsson, Henrik; Henry, Lucy; Messer, David; Ronnberg, Jerker – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
Children with intellectual disability (ID) were given a comprehensive range of executive functioning measures, which systematically varied in terms of verbal and non-verbal demands. Their performance was compared to the performance of groups matched on mental age (MA) and chronological age (CA), respectively. Twenty-two children were included in…

Pixner, S.; Zuber, J.; Hermanova, V.; Kaufmann, L.; Nuerk, H.-C.; Moeller, K. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Comparing numerical performance between different languages does not only mean comparing different number-word systems, but also implies a comparison of differences regarding culture or educational systems. The Czech language provides the remarkable opportunity to disentangle this confound as there exist two different number-word systems within…

Brankaer, Carmen; Ghesquiere, Pol; De Smedt, Bert – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The present study investigated numerical magnitude processing in children with mild intellectual disabilities (MID) and examined whether these children have difficulties in the ability to represent numerical magnitudes and/or difficulties in the ability to access numerical magnitudes from formal symbols. We compared the performance of 26 children…
