Narrative comprehension, memory, motion, depth perception, synesthesia, hallucination, and dreaming have long been objects of fascination for cognitive psychologists. They have also been among the most potent sources of creative inspiration for experimental filmmakers. Lessons in Perception melds film theory and cognitive science in a stimulating investigation of the work of iconic experimental artists such as Stan Brakhage, Robert Breer, Maya Deren, and Jordan Belson.

Imagine an eye unruled by man-made laws of perspective, an eye unprejudiced by compositional logic, an eye which does not respond to the name of everything but which must know each object encountered in life through an adventure of perception. How many colors are there in a field of grass to the crawling baby unaware of "Green"? How many rainbows can light create for the untutored eye? How aware of variations in heat waves can that eye be? Imagine a world alive with incomprehensible objects and shimmering with an endless variety of movement and innumerable gradations of color.
