Computer-generated motion pictures of random dot patterns on slanted planes translating along a horizontal axis were displayed to 40 undergraduates. The displays included combinations of 4 levels of texture gradients, corresponding to 0, 20, 40, and 60- slants, and 5 levels of velocity gradients, 0, 20, 40, 60-, and no motions. Ss were instructed to tilt a clear plastic plane to the same angle as the displayed plane. Slant judgments wee predictable from a combination of the ingradients, with greater weight given to velocity information. The relationship of the findings to gradient and perspective interpretations of slant perception is also discussed. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
