Response time per sensory modality.

<p>Subjects responded faster (lower median response times) and more consistently (lower mean within-subject variance) with visual than auditory task stimuli (<b>A</b>). Error bars depict standard error across subjects. There was a high correlation across subjects' response times between the two tasks (r = 0.883, p<.05) such that subjects with longer responses during the visual task also tended to take longer to respond with auditory targets as well (<b>B</b>). The shaded area emphases how this relative difference increases consistently across subjects.
