Paper Abstract

We report on several experiments that we designed to study the relative strength of visual attributes in the perception of texture. Our stimuli are composed of microelements that are arranged regularly in two-dimensional space. Each microelement can be characterized by the conjunction of several attributes (shape, size, color, etc.). Although the spatial regularity results in a "homogeneous" texture, we can manipulate the arrangement of selected attributes so as to break this homogeneity by forming textural patterns, whose discriminability can be tested experimentally. The stimuli allow flexibility in choosing the ways in which different attributes can be matched spatially to generate patterns. We have used these stimuli to study the roles of color, orientation, luminance and polarity in forming textures. Preliminary results indicate an inherent similarity between the mechanisms subserving texture perception and those mediating the perception of motion; the latter were studied with a similar type of stimuli. Finally, we report on a method for isolating the role of specific texture mechanisms by comparing the results of carefully selected experiments.
