Acoustic And Semantic Processing Of Speech And Non-Speech Sounds In Children With Autism Spectrum Disorders, Breanne D. Yerkes
Acoustic And Semantic Processing Of Speech And Non-Speech Sounds In Children With Autism Spectrum Disorders, Breanne D. Yerkes
UNLV Theses, Dissertations, Professional Papers, and Capstones
The processing of semantically meaningful non-speech and speech sounds requires the use of acoustic and higher-order information, such as categorical knowledge and semantic context. Individuals with an autism spectrum disorder (ASD) have been theorized to show enhanced processing of acoustic features and impaired processing of contextual information. The current study investigated how children with and without ASD use acoustic and semantic information during an auditory change detection task and semantic context during a speech-in-noise task. Furthermore, relationships among IQ, the presence of ASD symptoms and the use of acoustic and semantic information across the two tasks were examined among typically …
Acoustic Mediation Of Vocalized Emotion Identification: Do Decoders Identify Emotions Idiographically Or Nomothetically?, Michael Kenneth Lauritzen
Acoustic Mediation Of Vocalized Emotion Identification: Do Decoders Identify Emotions Idiographically Or Nomothetically?, Michael Kenneth Lauritzen
Theses and Dissertations
Most research investigating vocal expressions of emotion has focused on one or more of three questions: whether there exist unique acoustic profiles of individual encoded emotions, whether the nature of emotion expression is universal across cultures, and how accurately decoders can identify expressed emotions. This dissertation begins to answer a fourth question, whether there exist unique patterns in the types of acoustic properties persons focus on to identify vocalized emotions. Three hypotheses were tested: first, whether acoustic patterns are interpreted idiographically or nomothetically as reflected in a comparison of individual vs. group lens model identification ratios; second, whether there exists …
