Historical Models of Parsing and Unit Formation

How are the connectedness, coherence, and outlines of objects in a visual scene established? How during development do humans come to know which edges and contours go together to form objects? Historically, different answers have been given to such questions. Gestalt psychologists argued that our nervous systems are constrained, even at birth, to follow certain principles (e.g., closure, common movement, good continuation, proximity, and similarity) that specify how small pieces of a visual scene should be organized to form larger perceptual units or perceptual wholes (Helson, 1933; Koffka, 1935; Kohler, 1929; Wertheimer, 1923/1958). Other theorists have emphasized that an extended period of perceptual learning of visual and motor associations may be needed to determine the spatial arrangement of features that comprise individual forms (Hebb, 1949; Piaget, 1952).
