Which type of information improves the performance in a joint visuospatial task?

In the present study, we investigated how performance in a visuospatial collaborative task depends on the received type of information (i.e., performance feedback, information about the co-actor's actions, or both) in several experiments. In all experiments, the performance of the pair exceeded the individual performances and also the combined individual performances. Findings of the study  indicate which type of information is crucial for developing effective devision of labour strategies in collaborative visuospatial tasks. Moreover, findings are not only of interest for human-human interactions but also relevant for human-robot interactions.
