Atypical Prosody in Asperger Syndrome: Perceptual and Acoustic Measurements
Publication . Filipe, Marisa G.; Frota, Sónia; Castro, São Luís; Vicente, Selene G.
It is known that individuals with Asperger syndrome (AS) may show no problems with regard to what is said (e.g., lexical content) but tend to have difficulties in how utterances are produced, i.e., they may show prosodic impairments. In the present study, we focus on the use of prosodic features to express grammatical meaning. Specifically, we explored the sentence type difference between statements and questions that is conveyed by intonation, using perceptual and acoustic measurements. Children aged 8 and 9 years with AS (n = 12) were matched according to age and nonverbal intelligence with typically developing peers (n = 17). Although children with AS could produce categorically accurate prosodic patterns, their prosodic contours were perceived as odd by adult listeners, and acoustic measurements showed alterations in duration and pitch. Additionally, children with AS had greater variability in fundamental frequency contours compared to typically developing peers.

Prosody in Portuguese Children with High Functioning Autism
Publication . Filipe, Marisa; Frota, Sónia; Villagomez, Adrienne; Vicente, Selene G.
There is a lack of research investigating prosody in Portuguese children with autism. In this chapter, we analyze 15 Portuguese children aged 5–9 years with high-functioning autism (HFA) in comparison to their typically developing peers. We also evaluated nonverbal intelligence, vocabulary, phonological awareness, pragmatics, attention, and executive functions. Statistical analyses, using pairwise matching of nonverbal intelligence and chronological age, suggested that children with HFA have difficulties perceiving and imitating prosodic patterns, as well as difficulties understanding or effectively producing some of the communicative functions conveyed by prosody. Findings suggested a significant positive correlation between prosody and other language domains. Additionally, two case studies were conducted to further discuss the prosodic impairments.
