31. May 2018 : Are two heads better than one? – A review on group benefits in joint perceptual tasks, the influencing factors, and how to measure it

New publ.:

Wahn B, Kingstone A and König P. Group benefits in joint perceptual tasks: A review. DOI:10.1111/nyas.13843. ANNALS OF THE NEW YORK ACADEMY OF SCIENCES. Special Issue: The Year in Cognitive Neuroscience

Humans often collaborate in perceptual tasks to achieve a higher performance than performing the same task alone (i.e., attain a group benefit). In this review, Wahn et al. identify factors that influence collaborative strategies and the extent of group benefits in two frequently investigated joint perceptual tasks: visuospatial tasks and decision-making tasks. They also provide a framework of measures to assess group benefits in perceptual tasks.
