Abstract
A point-like stimulus was presented in a clockwise or
counterclockwise sequence at 3, 4, 6, or 12 uniformly spaced locations
around a circle in visual, tactile, or auditory space. In 4
experiments, the stimulators were (a) light-emitting diodes in the
frontal plane, (b) mechanical stimulators on the palm, (c) airpuff
nozzles around the head, and (d) loudspeakers around the head. For each
spatial separation and stimulus-onset asynchrony (SOA) between
successive stimuli around the circle, participants reported the
direction of motion. Within each modality, the SOA required for 75%
accurate discrimination of direction increased with the spatial
separations. A time-distance constraint akin to Korte's third law of
visual apparent motion can thus be obtained from responses that are
objectively classifiable as
correct
or
incorrect
(without relying on subjective reports of
"goodness" of apparent motion). Moreover, this time-distance
constraint evidently generalizes across sensory modalities.
