BCI for a brain state control in a dual-task paradigm
The brain resource is limited and it needs to be distributed among the different concurrent tasks. When the subject accomplishes the resource-demanding main task requiring sustained attention, the additional task leads to the reduction of resources allocated for the main task accomplishing. This additional task can be either important or caused by the distraction. Anyway, it causes a
performance decrease in the main task. In this paper, we propose a brain-computer interface (BCI) to control the cognitive performance of the visual task accomplishing in the presence of the additional (mental arithmetic) task. We demonstrate how the additional task affects the performance of the main task accomplishing.
