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…

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).…

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…

Recent evidence, however, suggests that children as young as 3 years of age understand that thought bubbles depict mental representations and that these…

An Australian comparison study of 26 children (mean age=10) with mild intellectual disabilities, 26 typical children of approximately the same mental age, and 26 children of approximately the same chronological age, found no mean differences on problem-solving abilities between the children with intellectual disabilities and children of comparable…
