ART, BEING PSYCHOLOGICAL, INCLUDES BOTH UNCONSCIOUS AS WELL AS CONSCIOUS PROCESSES OF THE BEHOLDER.  DEVELOPING THIS AWARENESS AND RECEPTIVITY OF THE ART OBJECT IS CALLED THE SENSITIVITY OF THE BEHOLDER.

ART STIMULATES MORE INTENSELY THAN COMMONPLACE OBJECTS OF THE WORLD THROUGH ITS INCLUSION OF METAPHORICAL DISCOVERIES LEFT FREE FOR A MULTI-INTERPRETIVE RESPONSE BY THE BEHOLDER.  IN OTHER WORDS, AMBIGUITY IS A FACTOR OF AESTHETIC PERCEIVING.

THE RESULTS OF AESTHETIC EFFORT CAN BE STUDIED EMPIRICALLY (FOR EXAMPLE BY SOCIAL CRITICISM OR SURVEY RATINGS) IN ORDER TO HELP THE ARTIST REFINE AND CLARIFY HIS FUTURE WORK WITH MORE PERDICTABLE  AUDIENCE REACTION TO HIS FUTURE EFFORTS.
