Gestalt and Human Vision

Paper Summary:

The paper shows that Gestalt theory contributed much to the study of human vision and object perception. It explains that the eye does not consciously select objects as was suggested in earlier theories. The writer explains that Gestalt theory proposes that the eye tends to group objects into meaningful units, and that this grouping is an organizational behavior. In summation, the writer states that the recognition theorists agree that the human eye is faced with a variety of difficulties when it undertakes the task of object perception and identification and that it is most often believed that recognition occurs when a comparison is made between visual input date and memory identification.

From the Paper:

"Early Gestaltists balked at the idea that object perception was merely a matter of physiology: fiber systems or conductors with fixed pathways which connect various sensory arenas in the central nervous system. Wertheimer asserted that no matter how complex these structures may be, they are inadequate in terms of explaining perceptual experience. [5] The nervous system is not a machine. Instead, it must be studied as a whole entity with all of its dynamical interactions. Gestaltists, however, failed to work out the details. "The computational theory of object perception includes a large body of experimental findings on visual performance, but was developed by Marr as a mathematical approach to the subject. Marr defined certain "processing stages" in visual perception and acknowledged that these stages are ones which could be realized on a computer. [6]"
