Description
We performed two experiments to examine how the spatial arrangement of two texture triangles, large and small, affects texture laciness. The texture of the triangles consisted of either horizontal or vertical lines. With the smaller triangle included in the interior of the larger, the percept of two pseudo-transparent triangles in different depth planes occurs for some arrangements. Twelve undergraduates rated the stimuli generated on a color CRT display according to texture laciness. The first experiment showed that the location of the small triangle inside the large one affected the laciness. The second experiment showed that the effect of the triangle location varied depending on the texture direction of the triangles. The results demonstrated a strong coupled effect of location and direction of texture on perceived laciness, which indicates that the laciness is determined by perceptual organization of the texture in the display.
