Human speed discrimination can be degraded by additional stimuli in close spatial and temporal proximity to the designated test target. In these experiments, observers judged the relative asynchrony between a pair of briefly flashed dots: speed discrimination for two-dot apparent motion. The addition of two irrelevant (interfering) flashed dots to the stimulus, which produces accelerating apparent motion, impaired speed discrimination. We call this impairment motion interference; adjacent… CONTINUE READING
