In conversation, the listener plays an active role in conversation success, specifically by providing "listener feedback" which signals comprehension and interest. Previous work has shown that frequency of feedback positively correlates with conversation success. Because individuals with ASD are known to struggle with various…

Difficulty listening in noisy environments is a common complaint of individuals with autism spectrum disorder (ASD). However, the mechanisms underlying such auditory processing challenges are unknown. This preliminary study investigated auditory attention deployment in adults with ASD. Participants were instructed to maintain or switch attention…

Autistic traits vary across the general population, and are linked with face recognition ability. Here we investigated potential links between autistic traits and voice recognition ability for personally familiar voices in a group of 30 listeners (15 female, 16-19 years) from the same local school. Autistic traits (particularly those related to…

Neural mechanisms that underlie language disability in autism spectrum disorder (ASD) have been associated with reduced excitatory processes observed as positive blood oxygen level dependent (BOLD) responses. However, negative BOLD responses (NBR) associated with language and inhibitory processes have been less studied in ASD. In this study,…

We re-evaluate conclusions about disfluency production in high-functioning forms of autism spectrum disorder (HFA). Previous studies examined individuals with HFA to address a theoretical question regarding speaker- and listener-oriented disfluencies. Individuals with HFA tend to be self-centric and have poor pragmatic language skills, and should…

Are there consistent markers of atypical prosody in speakers with high functioning autism (HFA) compared to typically-developing speakers? We examined: (1) acoustic measurements of pitch range, mean pitch and speech rate in conversation, (2) perceptual ratings of conversation for these features and overall prosody, and (3) acoustic measurements of…

We examined whether infants' preference for speech at 12 months is associated with autistic-like behaviors at 18 months in infants who are at increased risk for autism spectrum disorder (ASD) because they have an older sibling diagnosed with ASD and in low-risk infants. Only low-risk infants listened significantly longer to speech than to…

The study of four autistic children, aged six-nine, found support for the hypothesis that persistent pronominal errors by autistic children can be explained by failure to observe pronouns in speech addressed to another person, an aspect of language development in normal children. (Author/DB)

Two experiments evaluated the social interactions of 15 Asperger-type autistic subjects with either normal or schizoid control subjects. Asperger subjects tended to avoid gazing at the interviewer when the interviewer was talking. Results suggest that a lifelong absence of gaze response to social clues including speech may explain some features of…

Twelve autistic children (ages 4-6) were given a choice between their mothers' speech and the noise of superimposed voices. In contrast to comparison groups of mentally retarded and normally developing children, the autistic children actively preferred the superimposed voices or showed a lack of preference for either audio segment.

Eighty children, ages 3 to 17, with autism or Asperger's syndrome and mild to severe distress in the presence of some sounds received either auditory training or a control condition of listening to the same music. Significant improvements in behavior, severity of autism, and IQ were achieved and maintained for 12 months by both groups. (Author/DB)
