RESUMO
In this paper, we report on the results of our research, which is designed to address two broad questions about the cognitive and linguistic profile of Down syndrome: (1) Which domains of functioning are especially impaired in individuals with Down syndrome? and (2) Which aspects of the language and cognitive profile of Down syndrome are syndrome specific? To address these questions, we focused on three dimensions of the Down syndrome profile--receptive language, expressive language, and theory of mind--and made comparisons to individuals with fragile X syndrome, which is an X-linked form of intellectual disability. We identified Down syndrome impairments on all three dimensions that were substantially greater than those seen in nonverbal cognition and that were not shared by individuals with fragile X syndrome. Clinical implications of these findings are considered.

The purpose of this study was to investigate teacher speech and educational philosophies in inclusive classrooms with deaf and hearing students. Data were collected from language transcripts, classroom observations, and teacher interviews. Total speech output, Mean Length Utterance, proportion of questions to statements, and proportion of open to closed questions were calculated for each teacher. Teachers directed fewer utterances, on average, to deaf than to hearing students but showed different language patterns on the remaining measures. Inclusive philosophies focused on an individualized approach to teaching, attention to deaf culture, advocacy, smaller class sizes, and an openness to diversity in the classroom. The interpreters' role in the classroom included translating teacher speech, voicing student sign language, mediating communication between deaf students and their peers, and monitoring overall classroom behavior.
