The Effect of Visual Stimulus Properties in Global and Local Perception Processing

Abstract

The aim of the current research was to identify the effect of some visual stimulus characteristics globally and locally, and try to answer the following question: Does the size, density or position of the visual stimulus have an effect in global or local perception processing? To achieve this target, Navon's test was used to measure global and local perception processing, some characteristics of the original test were modified (Size, Density, Position) to study its effect in response time and mistakes number of the global and local. the sample consisted of 96 students from Kala moon University, divided into three equal groups: the size group, the density group, and the position group. The results of the research showed the superiority of global over local in terms of response time to visual stimuli and the number of mistakes in all cases studied. Which means that global processing is superior to the local one, even with the change in the size of the stimulus (small/large), the change in the element density and the change in the display location.
