Figure 1.
Schematic of matching task and behavioural results. (a) Illustration of example trials in the two attentional conditions. Under visual-tactile focus (left), the changes in the target stimuli are incongruent, as the tactile stimulus (black) increases in intensity while the visual stimulus (red) decreases. Under audio-visual focus (right), target change is congruent, since visual and auditory (green) stimuli both increase in intensity. (b) In each block, all possible stimulus configurations occurred with equal probability. Intensity changes are depicted by coloured plus/minus signs (colour coding as introduced in a). (c) Accuracy (ACC) in percentage correct. Error bars represent standard deviations. ATTENTION significantly affected accuracy of responses. (d) Reactions times in milliseconds (RTs). Error bars represent standard deviations. ATTENTION as well as CONGRUENCE significantly affected the timing of responses (Note: RTs were collected in our previous behavioural study16 from the same sample of participants).
