The Kinetic Depth Effect and Identification of Shape.
Abstract
This paper introduces a new method for assessing the effectiveness of kinetic depth stimuli for creating a percept of three-dimensional shape. The task is shape and motion identification, where each shape presented is one of a large lexicon of shapes. The shape consist of bumps and depressions on an otherwise flat ground. They vary in the number of bumps, their position and size. Using multi-dot representations of the shapes, identification is demonstrated to increase with dot numerosity and with the extent of depth portrayed. This task holds promise as a paradigm for examining objectively the cues necessary for the kinetic depth effect. Accurate performance on the task requires a global percept of three-dimensional shape, and is not prone to subject strategies using simple velocity measurement at a small number of spatial locations.
