Cognitive interaction during a collaborative attentional task

The modern trend in neuroscience and engineering is the developing systems allowing increase human physical and cognitive abilities through human-machine interaction. In these systems the human's condition is controlled by a brain-computer interface and assistance is activated when cognitive (or physical) performance decreases. In the current paper we consider the system, where the human's cognitive performance is enhanced due to cognitive interaction with another human. The proposed interface was tested at experimental sessions, in which the subjects were asked for a long time to solve the problem of classification of ambiguous visual stimuli of varying complexity. The proposed interface allows to increase the average productivity of a group of people due to the distribution of cognitive load between all participants.
