| Abstract(in English) | Vertically and horizontally arranged words, symbols and lines were presented at the center of the vision in order to compare the visual evoked field of each condition. RMS (Root Mean Square) of whole head, and the left and right temporal areas from all the subjects were calculated, and in every approximately 5 ms, the analysis of variance (ANOVA) was performed in the design of vertical or horizontal arrangement×stimulus type (2×3) to see significant difference in signal strength. Three major components, peaking at (1) l80-200ms (2) approximately 250ms and (3) approximately 370ms (N180, RP, P300, respectively), which appear only when processing the word stimuli were confirmed. Reaction of the vertically arranged words is consistently stronger than the horizontal ones in all the component, which suggested that recognizing vertically arranged texts possibly contains higher leveled or more difficult processes. The essential difference in the recognition process of vertically and horizontally arranged texts was distinguished, and thus, inefficiency in reading vertically arranged texts may not be only rooted by saccade or eye movements. |
