Description
- Abstract
- Social communication breakdowns have cascading impacts on the relationships, mental health, and quality of life of autistic youth. Interpersonal synchrony (IPS), the dynamic process through which conversation partners align their communicative behaviors to create shared meaning, has emerged as a potential mechanism through which differences in autistic expressive communication lead to communication breakdowns. However, the emergence of IPS in speech and language features of communication remains unknown. Speech and language IPS have been studied in isolation in the conversations of autistic children and adults but school-age developmental trajectories of IPS have been underexplored, missing the critical window of school-age development in which conversation becomes a central feature of friendships. Given well-documented SEX differences in autistic speech and language, trajectories of IPS emergence in autism are also likely to differ by child SEX. I propose to bridge these gaps by leveraging IPS data from naturalistic conversations collected in a SEX and diagnostic group balanced sample (n=200) of 4-8-year-old children (R01HD103895). For aim 1 i will characterize SEX and diagnostic group differences in speech and language features of IPS between children and a novel adult during a naturalistic conversation task. I predict that non-autistic children and females will evidence higher levels of IPS compared to autistic and male children. For aim 2 i will describe developmental trajectories of speech and language features of IPS across 18 months of development. I predict that IPS will increase over time, but that this increase will be slower for autistic children and male children than IT is for non-autistic children and female children. Finally, for aim 3 i will examine the role of IPS in speech and language development by establishing whether features of IPS are positively associated with later verbal ability and social communication. I predict that speech features of IPS will positively predict later social communication abilities and language features of IPS will positively predict later verbal ability. Training aims include advancing my theoretical foundation in interpersonal synchrony and technical skills in computational linguistics, acoustic analyses, bayesian statistics, and longitudinal measurement. This project will generate critical knowledge on the emergence of IPS in autism, SEX differences, and associations with effective communication. These insights will lay the groundwork for developing tailored supports that account for both developmental stage and SEX-specific needs of autistic communicators.
