Collective benefit in joint perceptual judgments: Partial roles of shared environments, meta-cognition, and feedback.

ABSTRACT: Recent research has demonstrated that two persons can optimally combine their observations to make better decisions when they can verbally communicate their confidence to each other. The present study investigated whether non-verbal interaction in a shared environment can be sufficient to achieve similar collective benefit. Pairs of individuals performed a localization task in a shared virtual 3D environment. In Experiments 1 and 2, partners had access to orthogonal viewpoints providing complementary information. The results showed robust collective benefit compared to individual performance from a single viewpoint, which could be obtained without any opportunity for verbal communication and even when no feedback about joint accuracy was provided (Experiment 2). When partners shared the sa
