Congratulations to Guy Theraulaz of the CRCA, winner of the 80|Prime call for projects for his ALTHEA project

This call for projects aims to support and strengthen interdisciplinarity between CNRS institutes.

ALTHEA project

Experimental analysis and modeling of collective choices in human groups

Coordinator: Guy Theraulaz, DR1-CNRS, INSB, Centre de recherche sur la cognition animale (CRCA), CBI, CNRS, Université de Toulouse, UPS, Toulouse, France

Partner: Clément Sire, DR2-CNRS, INP, Laboratoire de Physique Théorique, Université de Toulouse, UPS, Toulouse, France

Summary: The aim of this project is to study the influence of various forms of digital traces in human decision-making processes and their consequences on the dynamics of collective choices in groups of individuals. Combining experimental and modeling approaches, we will investigate under what conditions controlled interactions between individuals can lead a group to find the right solution to a problem. In particular, we will study the processes involved in collective search of information and in collective optimization choices in a minority game. The most innovative part of this project lies in the development of digital and virtual reality interfaces allowing a real-time control of the information exchanged between subjects and the quantification of the influence of digital information on individual and collective behavior.

Virtual reality setup used to analyze individual and collective choices in a minority game. Subjects equipped with a virtual reality headset (a) walk in a network of corridors (b, c) seeking at each fork to choose the corridor least used by the preceding pedestrians. In the immersive simulation, the virtual subjects react in real time to the behavior of the real subjects and it is possible to display the number of pedestrians that took each lane during a precise time interval (d)
