MENTAL IMAGERY IN auditory, sensual, and visual modes has played a central role in creative thought. Wolfgang Amadeus Mozart's auditory imagery permitted him to hear a new symphony "tout ensemble." The great French mathematician and philosopher Henri Poincaré's 'sensual imagery" led him to sense a mathematical proof in its entirety "at a glance." Albert Einstein's creative thinking occurred in visual imagery, and words were 'sought after laboriously only in a secondary stage" (Hadamard, 1954).
