Contemporary action understanding research has shown that cues guide our interpretation and prediction of others’ actions. This group of talks seeks to show the range kinds of cues that shape our action understanding, and the mechanisms by which they do so.

Mechanisms underlying forward simulation in action understanding
Dr Francesco Iani – Universita Di Torino
During action observation, people represent the observed action unfolding in time and this representation speeds up the recognition of the next action states compared to the backward states. In this talk we will discuss the nature of this mental stimulation as well as the possible mechanisms underlying action anticipation. We hypothesize that there are at least two processes: (1) an action prediction mechanism, by which people simulate the next states of the observed action through a representation of the action unfolding in time; (2) a goal prediction mechanism, by which people infer the final goal of the observed action based on the physical properties of the object.

Cues to other's higher-order mental states inform action predictions
Dr Katrina McDonough – University of Aberdeen
How we perceive and interpret the actions of others depends not only on action observations, but also action predictions. Here we show that cues to other's higher-order mental states inform predictions of their upcoming behaviour and guide action perception.

Communication through teaching: How expert pianists and novice students interact
through sound

Atsuko Tominaga – Central European University
In my talk, I will discuss how expert pianists produce and adapt teaching signals through their performances and how novice students detect such cues by listening to teachers’ performances.

Others’ social contexts guide our predictions of their actions
Dr Shaheed Azaad – Postdoctoral Researcher, Central European University
Recent work on action prediction has shown that contextual, non-kinematic, cues can inform our predictions of others’ actions. In this series of experiments, we show that others’ social contexts similarly guide action prediction.
Predicting others’ actions from their Social Contexts

According to predictive process accounts of perception, we identify others’ actions by rapidly forming and updating hypotheses about them as they unfold. Recent work has shown that non-kinematic cues, such as others’ affordances and intentions, inform our action predictions. We sought to explore whether others’ social contexts also guide our predictions for them. Across four experiments, we showed participants videos of an actor walking toward pieces of furniture either with (joint condition) or without (solo condition) a partner standing by the object. Participants indicated the last-seen location of the actor using a touch response, with displacement between joint and solo conditions indicating relative predictive bias toward the end of the actor’s trajectory. We found that responses were more predictive for joint videos but not when we instructed participants that actors would perform an action that did not require a partner. Results imply that others’ social contexts indeed guide our predictions for them.
