Rett Syndrome (RTT) is characterized by severe impairment in fine motor (FM) and expressive language (EL) function, making accurate evaluations of development difficult with standardized assessments. In this study, the administration and scoring of the Mullen Scales of Early Learning (MSEL) were adapted to eliminate the confounding effects of FM…

Kover, Sara T.; McCary, Lindsay M.; Ingram, Alexandra M.; Hatton, Deborah D.; Roberts, Jane E. – American Journal on Intellectual and Developmental Disabilities, 2015
Fragile X syndrome (FXS) is associated with significant language and communication delays, as well as problems with attention. This study investigated early language abilities in infants and toddlers with FXS (n = 13) and considered visual attention as a predictor of those skills. We found that language abilities increased over the study period of…

Shaw, Tracey A.; Porter, Melanie A. – Journal of Autism and Developmental Disorders, 2013
This study investigated emotion recognition abilities and visual scanning of emotional faces in 16 Fragile X syndrome (FXS) individuals compared to 16 chronological-age and 16 mental-age matched controls. The relationships between emotion recognition, visual scan-paths and symptoms of social anxiety, schizotypy and autism were also explored.…

Duijff, Sasja; Klaassen, Petra; Beemer, Frits; Swanenburg de Veye, Henriette; Vorstman, Jacob; Sinnema, Gerben – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
The purpose of this study was to explore the relationship between intelligence and visual motor integration skills in 5-year-old children with 22q11-deletion syndrome (22q11DS) (N = 65, 43 females, 22 males; mean age 5.6 years (SD 0.2), range 5.23-5.99 years). Sufficient VMI skills seem a prerequisite for IQ testing. Since problems related to…

Breckenridge, Kate; Braddick, Oliver; Anker, Shirley; Woodhouse, Margaret; Atkinson, Janette – British Journal of Developmental Psychology, 2013
Attentional problems are commonly reported as a feature of the behavioural profile in both Williams syndrome (WS) and Down's syndrome (DS). Recent studies have begun to investigate these impairments empirically, acknowledging the need for an approach that considers cross-syndrome comparisons and developmental changes across the different component…

Hocking, Darren R.; Thomas, Daniel; Menant, Jasmine C.; Porter, Melanie A.; Smith, Stuart; Lord, Stephen R.; Cornish, Kim M. – Developmental Science, 2013
Previous studies suggest that individuals with Williams syndrome (WS), a rare genetically based neurodevelopmental disorder, show specific weaknesses in visual attention and response inhibition within the visuospatial domain. Here we examine the extent to which impairments in attentional control extend to the visuomotor domain using a…
