Measurement of a visual motion aftereffect in the rhesus monkey.
A monkey was trained to discriminate between a shrinking and expanding test figure presented after steady fixation of the center of a rotating spiral. Differential shifts in the animal's perception of size constancy were found for clockwise and counter-clockwise rotation of the spiral. The magnitude of the aftereffect was within the range found in human subjects.
