Effects
of auditory vs. visual presentation on discrimination reaction
time

The
effects of auditory vs. visual presentation affecting discrimination
reaction time (DRT) were investigated in view of studying the channels
of presentation. Cane of the sip digits, "4, 5, 6, 7, 8, 9",
was presented auditory (A) or visually (V), but the Ss were to respond
only the odd number, saying "yes". Channels of presentation
were: (1) A-only, (2) V-only, (3) A-V redundant, (4) V-interference,
(5) A-interference, (6) left (L) only, (7) right (R) only. 6 Ss (female)
served in each condition. To avoid the phenomena accompanying stimulus
onset, digital discharge tube was applied to V-presentation. Digital
counter was used for measuring DRT. In generally, it seems that A-
(or R-) presentation is superior to V- (or L-) presentation on DRT.
A-presentation also was less interacting with each other than V-presentation.
