🚨🙋🏻‍♀️💬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 share @lukaszwalasek.bsky.social, Philip Newall, and I were selected for an AFSG exploratory grant!

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.

🚨 Out in Decision: are you interested in research on impulsivity, self-control, or time preferences, but are not quite sure how they fit together - look no further! @lukaszwalasek.bsky.social @hohwy.bsky.social A. Verdejo-Garcia and I offer a conceptual analysis with empirical evidence.
