The quantitative study of shape and pattern perception.

There is a need to extend the traditional psycho-physical methods to include the analysis of shapes or patterns. Heretofore studies designed to determine how form perception is influenced by various extrinsic factors have employed arbitrarily designed stimuli. This paper proposes several methods "for drawing 'random' patterns and shapes from clearly defined hypothetical populations, to which experimental results may then be generalized with measurable confidence." 27 references.
