Optimally interacting minds.

چکیده
In everyday life, many people believe that two heads are better than one. Our ability to solve problems together appears to be fundamental to the current dominance and future survival of the human species. But are two heads really better than one? We addressed this question in the context of a collective low-level perceptual decision-making task. For two observers of nearly equal visual sensitivity, two heads were definitely better than one, provided they were given the opportunity to communicate freely, even in the absence of any feedback about decision outcomes. But for observers with very different visual sensitivities, two heads were actually worse than the better one. These seemingly discrepant patterns of group behavior can be explained by a model in which two heads are Bayes optimal under the assumption that individuals accurately communicate their level of confidence on every trial.

Rooting opinions in the minds: a cognitive model and a formal account of opinions and their dynamics
The study of opinions, their formation and change, is one of the defining topics addressed by social psychology, but in recent years other disciplines, like computer science and complexity, have tried to deal with this issue. Despite the flourishing of different models and theories in both fields, several key questions still remain unanswered. The understanding of how opinions change and the wa...

We study mathematical models of the collaborative solving of a twochoice discrimination task. We estimate the difference between the shared performance for a group of n observers over a single person performance. Our paper is a theoretical extension of the recent work of Bahrami et al. (2010) from a dyad (a pair) to a group of n interacting minds. We analyze several models of communication, dec...
متن کاملWhat’s so critical about Critical Neuroscience? Rethinking experiment, enacting critique
In the midst of on-going hype about the power and potency of the new brain sciences, scholars within "Critical Neuroscience" have called for a more nuanced and sceptical neuroscientific knowledge-practice. Drawing especially on the Frankfurt School, they urge neuroscientists towards a more critical approach-one that re-inscribes the objects and practices of neuroscientific knowledge within webs...
