| Abstract(in English) | A visual search experiment was conducted to examine the frequency of target appearance as a factor affecting the reaction time required to detect a target among distracters. In our experiments of visual search for the conjunctively defined target, we manipulated the frequency of target present trials from 10% to 90%. Results showed that the observers took longer reaction times in high frequency conditions compared with low frequency conditions. This frequency effect was observed in visual search for feature defined target, too. This result suggests that frequency effect is not depending on target type. This frequency effect was observed only in negative response trials, but not in affirmative response trials. This difference indicates that the frequency effect influences the reaction time in the decision to terminate the visual search. These results suggest that the frequency effect provides a new approach to understand the process of visual search. |
