Abstract: This study aims at confirming the significance of search asymmetry and the existence of self-terminating effect, by investigating not only the search time but also the correction ratio. For the evaluation of search processing performance, correct ratio was an important index in addition to search time. Search time reflected a self-terminating effect depending on the condition of stimuli presentation, whereas correct ratio reflected performance accuracy in visual search. The former represents the total processing of human visual search performance and the latter represents human perception accuracy in early vision.

Keywords: early vision; search asymmetry; self-terminating effect; search processing; pop-out effect; search time; correction ratio; visual search processing; visual angle; stimuli; human perception; perception accuracy.
