The ability of children with Down syndrome to recognize expressions of emotion was compared to performance in typically developing and nonspecific intellectual disability groups matched on either MA or a performance-related measure. Our goal was to (a) resolve whether specific emotions present recognition difficulties; (b) investigate patterns of errors; and (c) explore the relationships among emotion-recognition ability and cognitive, linguistic, and adaptive behavior levels. Emotion-recognition ability in the Down syndrome group was significantly poorer than in the typically developing group overall, particularly for fearful expressions. Error patterns and relationships between task performance and assessment measures also differed across groups. Findings are consistent with a neurological explanation of specific deficits in sociocognitive functioning in children with Down syndrome.

Findings support previous evidence of emotion recognition abilities commensurate with overall developmental level in children with FXS or NSID, but not DS. They also suggest, however, that syndrome-specific difficulties may be subtle and detectable, at least in smaller-scale studies, only in comparison with TD matches, and not always across syndromes. Implications for behavioural phenotype theory, educational interventions and future research are discussed.

Speech intelligibility is particularly impaired, but whether speech is delayed or disordered is a controversial topic. Most studies suggest a delay, but no studies explore the relationship between cognitive or language skills and intelligibility. This study sought to determine whether severity of speech disorder correlates with language and cognitive level and to describe the types of errors, developmental or non-developmental, that occur in the speech of children and adolescents with DS. Methods & Procedures: 15 children and adolescents with DS (aged 10 to 18) were recruited. Participants completed a battery of standardised speech, language and cognitive assessments. The phonology assessment was subject to process analyses. Results from each test were correlated to determine relationships. Outcome & Results:People with DS present with deficits in receptive and expressive language that is not wholly accounted for by their cognitive delay. Receptive vocabulary is a strength in comparison to language skills, but it was unclear whether it is more advanced compared to non-verbal cognitive skills. The majority of speech errors were developmental in nature but all of the children with DS showed at least one atypical or non-developmental speech error. Conclusions: Children with DS present with speech disorders characterised by (often unusual) atypical errors alongside many developmental errors. Lack of correlation between speech and cognition or language suggests that the speech disorder in Down's syndrome is not simply due to cognitive delay.

The ability of three groups of children (with Down syndrome, age-matched with nonspecific developmental delay, and younger typically developing) to recognize identity and expression in adult faces was examined. In Experiment 1, the children with Down syndrome were equally proficient at recognizing unfamiliar faces when expression was varied but significantly poorer at recognizing expression overall, with a specific deficit in perceiving surprise and fear. In Experiment 2, using rotated faces, they were significantly worse at recognizing expression as well as at identifying known faces. These results, in conjunction with lack of any improvement with age, suggest that there is a specific deficit in processing facial expressions associated with Down syndrome, a finding consistent with the emerging picture of neurological disruption in this syndrome.
