“…These results fail to support a static account of the partwhole task based on perceptual goodness of the parts into the whole (Garner, 1974;van de Helm & Leeuwenberg, 1991). Perceptual organization can make use of earlier information if this is required by the task.…”

“…The power law relation above showed that subjective complexity of form was related to minimum required sides, which is consistent with the minimum coding idea proposed by Leeuwenberg and van der Helm (Leeuwenberg, 1968;van der Helm & Leeuwenberg, 1991). The power exponent is related to the level of symmetry, suggesting that the level of symmetry acts as the basis for classification of the different complexity of the forms.…”

Detection of a target grouping is expedited when the target display is preceded by presentation of an oscillating premask that includes priming elements presented intraphasically and below detection threshold at the display locations subsequently occupied by the target. Five experiments were performed to investigate how priming is affected by both the complexity and the geometry of prime/target forms. Experiment 1 showed that the subjective complexity of different polygons was coded in accord with an objective measure of form complexity. Experiments 2 and 3 revealed oscillatory priming to increase as a function of the subjective complexity of prime/target forms when those forms were regular and predictable. However, Experiments 4 and 5 showed that this relation did not hold when the prime/target forms were irregular and unpredictable. Taken together, it is argued that both subjective complexity and the Prägnanz quality of the prime/target forms come to determine the magnitude of priming. These results are discussed with reference to current physiological hypotheses regarding perceptual organization.

In visual occlusion 2 amodal-completion tendencies occur frequently. One tendency leads toward the simplest completed shape (a global completion) and the other to a shape for which the completion itself is as simple as possible (a local completion). Two experimental paradigms were used to test the strengths of these completion tendencies: a drawing task and a simultaneous matching task. The experimental results support the notion that the preference for either a global or a local completion is the consequence of a competition between interpretations. Finally, the authors discuss how the preference for a completion can be predicted by a model that is based on a quantification of both global and local aspects.
