🚨🙋🏻♀️💬Check out this exciting work by @cyberming.bsky.social showing that adults use a modality-independent mechanism for interpreting iconic speech and gesture cues. Very proud supervisor. Bonus, it's #OpenAccess ! #AcademicChatter #NewPaper #Gesture #Speech #Multimodality
Thrilled to see my first publication out in PB&R with @sotarokita.bsky.social and @suzanneaussems.bsky.social! Adults interpret novel verbs using iconic speed cues in speech prosody and hand gesture, with a small but reliable link across modalities.

We'll study how gambling experiences relate to the main gambling harm measuring tool—the PGSI. Understanding the person behind PGSI scores will enable better harm detection/prevention.

New paper with Tong Liu and Arndt Broeder, just accepted in Cognition. We test novel qualitative predictions from sampling-based models of probability estimation in an event ranking task. Results provide evidence for the idea that mental sampling underlies probability judgements.
