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…

Carney, Daniel P. J.; Brown, Janice H.; Henry, Lucy A. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
Williams (WS) and Down (DS) syndromes are characterised by roughly opposing ability profiles. Relative verbal strengths and visuospatial difficulties have been reported in those with WS, while expressive language difficulties have been observed in individuals with DS. Few investigations into the executive function (EF) skills of these groups have…

Duarte, Cintia Perez; Covre, Priscila; Braga, Ana Claudia; de Macedo, Elizeu Coutinho – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Individuals with Down syndrome (DS) tend to have impaired verbal short-term memory (STM), which persists even when visual support is provided for carrying out verbal tasks. Objective: The current study aims to investigate whether visuospatial support, rather than just visual, can compensate for verbal STM deficits in these individuals. The…

Kleemans, Tijs; Segers, Eliane; Verhoeven, Ludo – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The present study investigated to what extent children with specific language impairment (SLI) differ in their early numeracy skills, when compared to normal language achieving (NLA) children. It was also explored which precursors were related to the early numeracy skills in both groups. Sixty-one children with SLI (6; 1 years) and 111 NLA…

Gau, Susan Shur-Fen; Chiang, Huey-Ling – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
Deficits in short-term memory are common in adolescents with attention-deficit/hyperactivity disorder (ADHD), but their current ADHD symptoms cannot well predict their short-term performance. Taking a developmental perspective, we wanted to clarify the association between ADHD symptoms at early childhood and short-term memory in late childhood and…

van der Molen, Mariet J. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
The validity of Baddeley's working memory model within the typically developing population, was tested. However, it is not clear if this model also holds in children and adolescents with mild to, borderline intellectual disabilities (ID; IQ score 55-85). The main purpose of this study was therefore, to explore the model's validity in this…

Van der Molen, M. J. W.; Huizinga, M.; Huizenga, H. M.; Ridderinkhof, K. R.; Van der Molen, M. W.; Hamel, B. J. C.; Curfs, L. M. G.; Ramakers, G. J. A. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
The present study examined the cognitive profile in Fragile X Syndrome (FXS) males, and investigated whether cognitive profiles are similar for FXS males at different levels of intellectual functioning. Cognitive abilities in non-verbal, verbal, memory and executive functioning domains were contrasted to both a non-verbal and verbal mental age…
