Investigating the who, what, where, when, why and how of action and decision coordination.
In case you want to see how movement speed reflects subjective utility in real time!

Or indeed other mammals!

Thanks! Looking forward to seeing what you think. I wonder if we could see something like this in great apes?

This highlights the role of action understanding in learning about stimuli in the environment without the need for trial and error or explicit communication—simply by allowing us to ‘read’ value from how others approach things in our environment.

This demonstrates that the synchrony by which a group plans and executes contributions to a public good influence judgments of how cooperatively the group acted. This highlights the importance of action dynamics for understanding cooperation.

For both experiments, estimates of how much was in the pot were higher for synchronous than asynchronous groups, demonstrating that the temporal dynamics of an interaction contain signals of a group’s level of cooperativity.

Experiment 1 (N = 136 adults) manipulated the synchrony between players’ decision-making time, and Experiment 2 (N = 136 adults) manipulated the synchrony between players’ decision-implementing movements.

Participants watched animations of actors deciding how much to donate in a public-goods game and using a mouse to drag donations to a public pot. Participants then estimated how much was in the pot in total (as an index of how cooperative they thought the group members were).

Considering that synchrony in rhythmic interactions signals cooperative attitudes within a group, we aimed to investigate whether synchronous group behavior within an economic interaction raises expectations about group members acting in line with the collective interest.

It’s all in the hands! The next time someone gives you a birthday gift, look at how they are moving to decide whether you really want to invite them to the party!

We found that people prefer to interact with actors who implement cooperative decisions quickly or with smooth and direct movements, as this reflects confidence about a decision.
