Determinant factors of global /local processing dominance in visual hierarchical patterns

Abstract

Two experiments are reported examining whether the size (3 and 15 degrees of visual angle) and exposure duration (10 and 200 msec) of stimuli interacted in determining global/local processing dominance using stimuli whit global and local levels located at the same (Experiment 1) or different retinal locus (Experiment 2). The results showed that global/local processing dominance depends on the size and eccentricity of global and local information. The exposure duration of stimuli modulated global/local dominance processing depending on both, the size of the stimuli and the same/different eccentricity of global and local information.
