Abstract  This experiment is performed to investigate the RT difference inrecognition between the global-directed attention and local-directedattention, with compound Chinese characters made up of many smallerones as material. Visual angle of the stimulus is varied systematically tosee if the relative size of global pattern and local elements contributeto the occurrence of the RT difference between the two attentionconditions. The results show that in normal situation, the response toglobal pattern is significantly faster than that to local elements, and theinfluence of different visual angles on the RT difference is notsignificant. This suggests that the process of visual informationextraction begins with the global processing. In other words, globalprecedence exists, and it is the global precedence, not the relative size,which causes the significant RT difference between the global-directedattention and local-directed Attention.
