The authors carried out 2 experiments designed to cast light on the
locus of redundancy gain in simple visual reaction time by using a
stop-signal paradigm. In Experiment 1, the authors found that single
visual stimuli were more easily inhibited than double visual stimuli by
an acoustic stop signal. This result is in keeping with the idea that
redundancy gain occurs prior to the ballistic stage of the stop-signal
task. In Experiment 2, the authors found that the response to an
acoustic go signal was more easily inhibited by a double than by a
single visual stop signal. This result provides conclusive evidence for
a redundancy gain in the stop process-in a process that does not
involve a motor response but rather its inhibition.
