Abstract

type:Article

A previous study demonstrated that change blindness could be avoided when a gray monotonous distractor is presented monocularly. This result might be because the distractor was not perceived in a monocular presentation. Hence, change blindness when a more perceivable distractor was presented was investigated. We conducted the flicker paradigm task and then the distractor was presented binocularly and monocularly. The distractor was a Mondrian stimulus that had various colors and numerous edges. We manipulated the luminance of the Mondrian distractor because it was supposed that a higher luminance distractor became more perceivable even in the monocular condition. As a result, change blindness occurred even when the distractor was presented monocularly. Moreover, the higher the luminance of the Mondrian stimulus became, the more frequently change blindness occurred both in the binocular and monocular conditions. However, more alternations were needed to detect the change in the binocular condition. These results revealed that change blindness might require perception of the distractor, and even though change blindness occurred in the monocular condition, participants could detect the change earlier compared with in the binocular condition.
