We examined whether the effective visual field to identify target figure would be enlarged by the prime stimulus, which is presented at the central field of view. The target was presented from 1.00 to 9.25deg. of horizontal eccentricity. In experiments I and II, we varied the type of information given just prior to presentation of a geometric target figure, and we analyzed the reaction time and percent of correct responses to identify target under several conditions. By experiment I, it was found that direct prime information in the form of the target figure itself (Match condition) provided more spatial and temporal effects at the non-Match condition. Experiment II showed that semantic prime information in the form of figure's name by characters was also most effective than other conditions, but it was only for temporal aspect.
