Abstract/OtherAbstract:
It is widely accepted that motion and color are processed in separate brain areas of primates. Numerous studies on monkeys suggest that neural mechanisms responsible for motion processing respond faster than those for color. Recent studies on humans, however, provide contradictory evidence. Is this discrepancy due to a gap between species (animal vs. human), or between measures (neurophysiological vs. behavioral)? To help resolve this issue, event-related potentials were acquired as human participants viewed motion and color stimuli. Results indicated that the physiological response evoked by motion arose earlier than that by color, which is consistent with previous findings in animals. This temporal precedence of motion signal processing over color was corroborated in a parallel behavioral experiment.
