The ability to flexibly adapt to the changing demands of the environment is often reported as a core deficit in fragile X syndrome (FXS). However, the cognitive processes that determine this attentional set-shifting deficit remain elusive. The present study investigated attentional set-shifting ability in fragile X syndrome males with the…

Estigarribia, Bruno; Martin, Gary E.; Roberts, Joanne E.; Spencer, Amy; Gucwa, Agnieszka; Sideris, John – Applied Psycholinguistics, 2011
We examined recalled narratives of boys with fragile X syndrome with autism spectrum disorder (FXS-ASD; N = 28) and without ASD (FXS-O; N = 29), and compared them to those of boys with Down syndrome (N = 33) and typically developing (TD) boys (N = 39). Narratives were scored for mentions of macrostructural story grammar elements (introduction,…

Iacono, Teresa; Torr, Jennifer; Wong, Hui Yi – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
Studies into the effects of ageing on language in adults with Down syndrome (DS) have tended to rely on measures that lack sensitivity to change because they fail to explore across linguistic domains or rely on proxy reports. The study aim was to use measures of receptive and expressive language from studies of younger individuals with DS in…

Lorusso, M. L.; Galli, R.; Libera, L.; Gagliardi, C.; Borgatti, R.; Hollebrandse, B. – Clinical Linguistics & Phonetics, 2007
It is a matter of debate whether the development of theory of mind (ToM) depends on linguistic development or is, rather, an expression of cognitive development. The study of genetic syndromes, which are characterized by intellectual impairment as well as by different linguistic profiles, may provide useful information with respect to this issue.…

Evans, David W.; Canavera, Kristin; Kleinpeter, F. Lee; Maccubbin, Elise; Taga, Ken – Child Psychiatry and Human Development, 2005
This study compared the fears and behavior problems of 25 children with an autism spectrum disorder (ASD), 43 children with Down syndrome (DS), 45 mental age (MA) matched children, and 37 chronologically age (CA) matched children. Children's fears, phobias, anxieties and behavioral problems were assessed using parent reports. Significant…
