Joint affordance perception

Project description

Two heads may be better than one, but each may perceive options differently

When two people act together to achieve a joint goal, the dyad might have an emergent set of affordances or behavioural possibilities that may not represent a simple integration of those for each individual acting alone. Furthermore, each person's perception of what those affordances are plays a role in the joint action and in each person's activities. The EU-funded JAP project is investigating joint affordance perception through the lens of behavioural and neurophysiological data to better understand how it is impacted by attention, perception and social bonds. Using a stimulus–response paradigm, the researchers will evaluate behavioural measures such as response time and neural correlates as well as electroencephalogram data to shed light on how we can form joint action plans quickly and effectively.


When acting on the environment with another, it is critical that we understand the actions made possible by not only the properties of the environment, but by the capacity of the dyad. How we perceive these action possibilities, or affordances, for the dyad is a fundamental question in understanding joint action. The proposed project, JAP, aims to provide one of the first systematic and interdisciplinary – combining behavioural and neurophysiological data – investigations into the conditions under which affordances for the dyad (or joint affordances) are perceived, as well as the processes that underpin them.

The present project will use object-based stimulus-response compatibility paradigms, which produce response time and error data that can be used to measure affordance-elicited motor activation. Additionally, eye-tracking and electroencephalogram (EEG) data will be collected during these tasks to answer questions about the processes by which joint affordances are perceived. This data will be used to study: (1) the role of attention in joint affordances, (2) how perceiving others’ actions informs one’s own affordance perception, and (3) how social bonds modulate affordance perception.

Results from the proposed studies will provide novel insight into how we can rapidly and efficiently form joint action plans that account for action-relevant properties of the dyad and environment.
