(1993) proved to be a landmark in placing the Gestalt notion of continuity on a firmer scientific basis.

But, by changing the surroundings, as shown in Figure 6.17(c), the irregular shape that was perceived as a gap in Figure 6.17(b) can be made to become the figure.Ī set of experiments by Field et al. Closed contour, symmetry, and the surrounding white area all contribute to the perception of the two shapes in Figure 6.17(b) as figures, as opposed to cut-out holes. All of the Gestalt laws contribute to creating a figure, along with other factors that the Gestalt psychologists did not consider, such as texture segmentation. The perception of figure as opposed to ground can be thought of as part of the fundamental perceptual act of identifying objects. The area between the green shapes in (c) is generally not seen as a figure. (b) The green areas are seen as figures because of several Gestalt factors, including size and closed form. It is also easier to perceive patterns that are oriented horizontally and vertically as objects. (a) The black areas are smaller and therefore more likely to be perceived as an object. Eight Gestalt laws are discussed here: proximity, similarity, connectedness, continuity, symmetry, closure, relative size, and common fate (the last concerns motion perception and appears later in the chapter). The Gestalt laws easily translate into a set of design principles for information displays. These are robust rules that describe the way we see patterns in visual displays, and, although the neural mechanisms proposed by these researchers to explain the laws have not withstood the test of time, the laws themselves have proved to be of enduring value. They produced a set of Gestalt laws of pattern perception. The work of the Gestalt psychologists is still valued today because they provided a clear description of many basic perceptual phenomena. The word Gestalt simply means “pattern” in German.

The group consisted principally of Max Westheimer, Kurt Koffka, and Wolfgang Kohler (see Koffka, 1935, for an original text). The first serious attempt to understand pattern perception was undertaken by a group of German psychologists who, in 1912, founded what is known as the Gestalt school of psychology.
