Abstract

The hypothesis that perceived dimensionality of projection drawings is influenced by perceived organization was tested in two experiments. Organization was biased by coloration: The drawings were (a) uncolored, (b) colored in ways that emphasized plausible three-dimensional parts of the represented objects, or (c) colored in ways that emphasized two-dimensional (2D) parts of the drawings themselves. In Experiment 1, subjective ratings of three-dimensionality (3D) were greater for the 3D-biased stimuli than for the unbiased stimuli, and ratings for the 2D-biased stimuli were lower than for the unbiased stimuli. Similar results were obtained in Experiment 2 in which latencies to perceive the drawings three-dimensionally were measured. The 3D-biased stimuli were seen in depth more quickly than the unbiased stimuli, and the 2D-biased stimuli were seen in depth more slowly than the unbiased stimuli. Additional results on the relation between ratings and latencies suggest that latencies are affected more strongly by object complexity than are ratings.
