UNLABELLED Recognition of the facial expressions of emotions is a critical communicative system early in development and continues to play an important role throughout adulthood. In the past, the results of developmental studies of emotional facial recognition have often conflicted. The present study was designed to examine the development of emotional(More)
OBJECTIVE The purpose of this study was to investigate the effects of specific types of tasks on the efficiency of implicit procedural learning in the presence of developmental dyslexia (DD). METHODS Sixteen children with DD (mean (SD) age 11.6 (1.4) years) and 16 matched normal reader controls (mean age 11.4 (1.9) years) were administered two tests (the(More)
Recent studies on subjects with Williams syndrome (WS) have revealed a particular facility for language, rarely observed in other mental retarded populations, inspiring much belief in the independence of language from cognition. Lexical and morphosyntactic abilities of 17 Italian WS individuals, between 4.10 and 15.3 years of age, were evaluated both in(More)
Important claims have been made regarding the contrasting profiles of linguistic and cognitive performance observed in two genetically based syndromes, Williams syndrome (WS) and Down syndrome (DS). Earlier studies suggested a double dissociation, with language better preserved than nonverbal cognition in children and adults with WS, and an opposite profile(More)
Williams syndrome (WS) is a rare genetic condition characterised by intellectual disability, typical facial dysmorphology and several medical anomalies. A specific neuropsychological profile with a dissociation between language (relatively preserved) and visuo-spatial abilities (more seriously impaired) has been hypothesised in these children. Memory(More)
Executive functions are a set of high cognitive abilities that control and regulate other functions and behaviors and are crucial for successful adaptation. Deficits in executive functions are frequently described in developmental disorders, which are characterized by disadaptive behavior. However, executive functions are not widely examined in individuals(More)
The aim of this study was to investigate the role of several specific neurocognitive functions in developmental dyslexia (DD). The performances of 60 dyslexic children and 65 age-matched normally reading children were compared on tests of phonological abilities, visual processing, selective and sustained attention, implicit learning, and executive(More)
To investigate the relationship between language acquisition and cognition, we evaluated linguistic abilities in 12 Italian-speaking children with Williams syndrome (WS) and 12 with Down syndrome (DS) of comparable global cognitive level. Another control group included 12 typically developing (TD) children, matched for mental age. Linguistic measures(More)
OBJECTIVE Chromosome 22q11.2 deletion syndrome is a neurogenetic disorder associated with high rates of schizophrenia and other psychiatric conditions. The authors report what is to their knowledge the first large-scale collaborative study of rates and sex distributions of psychiatric disorders from childhood to adulthood in 22q11.2 deletion syndrome. The(More)
Although some studies have reported subtle language deficits following early focal brain lesions (EFBL), most studies find no evidence for differential language outcomes as a function of lesion side or lesion type in children with congenital injuries to one side of the brain. However, recent prospective studies of the first stages of language development in(More)
