A02 - Prosody on the spectrum: A comprehensive resource for studying and understanding linguistic prosody in Autism

Simon Wehrle

The website Prosody on the Spectrum is a dedicated repository with the aim of providing a comprehensive overview and support the exploration of linguistic prosody within the context of Autism Spectrum Disorder (ASD). It was created to accompany the open-access review article "Linguistic Prosody in Autism Spectrum Disorder—An Overview" (Grice, Wehrle, Krüger, Spaniol, Cangemi & Vogeley, 2023) published in Language and Linguistics Compass. The repository is intended to function as a centralized, up-to-date platform for identifying relevant research.

The review is sorted by prosodic function, ranging from lexical stress and syntactic structure to speech acts and emotional expression. Drawing on insights from 51 studies, the review article in its published form offers a comprehensive overview of findings on the perception and production of prosody in ASD.

Acknowledging the inherent challenges and intricacies involved in studying prosody and ASD, the repository aims to foster collaboration and knowledge exchange. By curating figures (see e.g. Figure 1), tables, and summaries, it provides researchers with a collection of resources for comparative analyses and hypothesis generation. Furthermore, the commitment to ongoing updates ensures that researchers remain informed about the latest developments in the field. The repository is currently kept up-to-date by inviting researchers in the field to submit new related work via an online form, with the website updated accordingly. A Shiny app for the same purpose is in development.

Prosody on the Spectrum serves as a highly valuable resource, offering researchers a platform for exploration and discovery in the critical area of prosody and ASD research. More broadly, we hope to offer an inspiring model for future review papers in the pairing of a conventional, static review article with a freely accessible associated repository that is updated continuously.
