Schematic of the experimental runs. Runs were set-up as a block design with a single trial consisting of five 30-40 sec blocks of the specific cognitive task alternating with five 30-40 sec blocks of the IDX. The cognitive tasks were - completing three letter word stems (WSC) and searching for a line bisecting a circle in a random array of circles (VS). Starting order of the task was counterbalanced between participants.
