Prosody production atypicalities are a feature of autism spectrum disorders (ASDs), but behavioral measures of performance have failed to provide detail on the properties of these deficits. We used acoustic measures of prosody to compare children with ASDs to age-matched groups with learning disabilities and typically developing peers. Overall, the group with ASD had longer utterance durations on multiple subtests on a test of prosodic abilities, and both the ASD and learning disabilities groups had higher pitch ranges and pitch variance than the typically developing group on one subtest. Acoustic differences were present even when the prosody was used correctly.These …

This study examines the processing of prosodic cues to linguistic structure and to affect, drawing on fMRI and behavioral data from 16 high-functioning adolescents with autism spectrum disorders (ASD) and 11 typically developing controls. Stimuli were carefully matched on pitch, intensity, and duration, while varying systematically in conditions of affective prosody (angry versus neutral speech) and grammatical prosody (questions versus statement). To avoid conscious attention to prosody, which normalizes responses in young people with ASD, the implicit comprehension task directed attention to semantic aspects of the stimuli. Results showed that when perceiving prosodic cues, both affective and grammatical, activation of …
Sensitivity To Probabilistic Orthographic Cues To Lexical Stress In Adolescent Speakers With Autism Spectrum Disorder And Typical Peers, Joanne Arciuli, Rhea Paul
Sensitivity To Probabilistic Orthographic Cues To Lexical Stress In Adolescent Speakers With Autism Spectrum Disorder And Typical Peers, Joanne Arciuli, Rhea Paul

Lexical stress refers to the opposition of strong and weak syllables within polysyllabic words and is a core feature of the English prosodic system. There are probabilistic cues to lexical stress present in English orthography. For example, most disyllabic English words ending with the letters “-ure” have first-syllable stress (e.g., “pasture”, but note words such as “endure”), whereas most ending with “-ose” have second-syllable stress (e.g., “propose”, but note examples such as “glucose”). Adult native speakers of English are sensitive to these probabilities during silent reading. During testing, they tend to assign first-syllable stress when reading a nonword such as …
Cognitive, Behavioral, And Adaptive Functioning In Fragile X And Non-Fragile X Retarded Men, E. Dykens, J. Leckman, Rhea Paul, M. Watson
Cognitive, Behavioral, And Adaptive Functioning In Fragile X And Non-Fragile X Retarded Men, E. Dykens, J. Leckman, Rhea Paul, M. Watson

The cognitive, behavioral, and adaptive functioning of 12 men with fragile X syndrome (aged 23 to 62 years) was systematically assessed and compared to two matched groups of retarded men without fragile X syndrome residing at the same institution. The fragile X group was largely indistinguishable from the comparison groups on the cognitive, behavioral, and adaptive measures. Fragile X patients were, however, significantly more likely to have achieved levels of adaptive functioning commensurate with their intellectual abilities. Fragile X subjects who had similarly affected siblings emerged as significantly higher-functioning in all areas than Fragile X subjects who did not have …
