Brunamonti, Emiliano; Pani, Pierpaolo; Papazachariadis, Odysseas; Onorati, Paolo; Albertini, Giorgio; Ferraina, Stefano – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Inhibition of inappropriate responses allows to shape the motor behavior accordingly to the context in which a subject acts and is an essential executive function. Inhibition has been poorly investigated in Down Syndrome (DS) patients. We tested, using a countermanding task, the inhibitory control in a group of DS patients and in a group of…

Research on theory of mind (TOM) has provided a major contribution to the understanding of developmental disorders characterized by atypical social behaviour. Yet, there is still little consensus relative to TOM abilities in Williams syndrome (WS). This study used visual and verbal tasks to investigate attribution of intentions in individuals with…

The study of affect comprehension in 15 children with pervasive developmental disorders (ages 7-10) and normal children matched for mental age found that the disabled children were impaired on affect matching compared to the controls and were impaired on face and affect matching relative to their own performance on object matching.

Seibert, Jeffrey M.; And Others – Intelligence, 1984
Do stage-related patterns of early cognitive development reported for normally developing children also characterize at-risk and handicapped children when mental age organization of data is used? Mental age predicted Piagetian-based cognitive levels one to three but did not predict highest-level symbolic functioning in 95 handicapped children.…

Schafer, D. Sue; And Others – Journal of the Division for Early Childhood, 1987
Investigation of the extent to which various factors were associated with observed developmental gains in developmentally-delayed young children (N=83) revealed that potential predictors of overall child progress included test score derivatives, number of assessments and home visits, mother's age, child's age at initial testing, and medical risk…
