The project addressed three research objectives:
1. Establish and elaborate the link between group size and joint agency.
2. Test whether these effects differ for social agents versus mere objects.
3. Identify how social role (leader vs. follower) influences joint agency.
Over the reporting period, these objectives were achieved through six experiments across multiple studies.
Experiments 1–4 (Galang et al., 2025, Journal of Experimental Psychology: General) demonstrated that the sense of agency increases with group size, with stronger effects for social agents compared to mere objects.
Experiments 4–6 (Nisanci, Formica, Brass, & Galang, in prep.) showed that leading a group enhances agency, while following reduces it.
All studies used pre-registered designs and included both implicit (e.g. intentional binding) and explicit (self-report) measures of agency. The work generated a substantial body of research outputs:
5 peer-reviewed publications, including in Cognition, Consciousness and Cognition, and Journal of Experimental Psychology: General.
2 manuscripts under review and 6 in preparation.
Side projects related to the grant objectives, examining topics such as rule-breaking, imitation, social exclusion, and group dynamics, further extended the scientific impact.
