.— The principle of perceptual vector analysis proposed by Johansson (1W) implicitly assumes the organism to be equipped with physiological systems sensitive to common and divergent components of change in the proximal stimulation. The present investigation was designed to study these units by means of the after‐effect paradigm. It was found that prolonged viewing of complex changes produced after‐effects of motion in depth and changing form specific to the common and divergent components of change in the stimulation. Data supported an explanation of these after‐effects in terms of adaptation of units selectively sensitive to different kinds of motion vectors.
