Co-Perception: Sharing experience without coordination

Abstract

This talk explores the concept of co-perception, which differs from the traditional notions of joint attention and action. 
Co-perception encompasses the ability to discern objects and spaces perceived by others from those kept private, without relying on complex mind-reading or mutual coordination. This concept provides a new understanding of social scenarios, from shared contexts to competitive interactions, and the talk will present evidence on how sharing experiences extends beyond affective responses to impact perceptual processes.

About the speaker

Ophelia Deroy is professor of Philosophy of Mind and Neuroscience at the Ludwig Maximilian University in Munich, and a member of the Faculty of Philosophy and the Munich Center for Neuroscience. She directs an research group combining philosophical, behavioural and computational methods, and has published widely on perception, metacognition and social cognition. She is also involved in work with museums, including Tate Galleries, Biotopia, Getty, the Museum of tomorrow, and policy-makers to evaluate and improve collective experiences and access to science.

Shared responsibility in collective decisions

Abstract

Research investigating collective decision-making has focused primarily on the improvement of accuracy in collective decisions and less on the motives that drive individuals to make these decisions. We argue that a strong but neglected motive for making collective decisions is minimizing the material and psychological burden of an individual’s responsibility. Making difficult decisions with others shields individuals from the consequences of negative outcomes by reducing regret, punishment and stress. Considering shared responsibility as a key motivation to join groups helps understand behaviours with societal implications such as political voting, committing norm violations, predicting natural disasters and making health-related decisions.

About the speaker

Bahador Bahrami is from Tehran, Iran. He got his MD from Tehran University of Medical Sciences in 2003 and then moved to London to do a PhD in cognitive neuroscience of consciousness in the human brain which he finished in 2008. After his phd bahador came to Aarhus (2008-10) to work with Andreas Roepstorff and Chris Frith. This period had a very profound impact on his research and has shaped his work ever since. He went back to London in 2010  where he founded the Crowd Cognition research lab. In 2018 he moved his lab to  Ludwig  Maximilian Universität in Munich Germany where he is now. Bahador's research focuses on the cognitive and neurobiological basis of interactive decision making between human-human and more recently, human-AI agents.
