Conversational turn-taking feels effortless, but it's a complex dance. We find social context—who you're talking to and what you're talking about—fundamentally changes conversational dynamics in both autistic & TD children. 1/

Social Context Matters for Turn‐Taking Dynamics: A Comparative Study of Autistic and Typically Developing Children
Engaging in fluent conversation is a surprisingly complex task that requires interlocutors to promptly respond to each other in a way that is appropriate to the social context. In this study, we dise...

📢Our peer-reviewed article about the AffectTracker is finally out! 😲🕹️📈
Traditional methods for rating emotion often miss the dynamic, moment-to-moment nature of feelings. We designed a tool to capture this continuous affective experience in real-time during dynamic emotional stimulation.

I've said it before, and I will say it again:
It's astonishing how emotionally aversive revisions are, even in the best possible case (reviewers are positive and have very actionable remarks).
Or at least that's how I work; if anybody has some good recommendations for coping, do let me know 😂
