contingent attentional capture
Contingent attentional capture occurs when a stimulus property captures an observer's attention, usually related to the observer's top-down attentional set for target-defining properties. This study examined whether contingent attentional capture occurs for a stimulus property that does not define the target by itself, but is congruent with the target-defining property. In an RSVP stream, we defined the target by a color (e.g., a green-colored Japanese Kanji character). Before the target onset we presented a distractor that referred to the target-defining color (e.g., a white-colored Kanji character with the meaning "green"). We observed that the distractor produced contingent attentional capture which was revealed by a deficit in identifying the subsequent target. This result suggested that the attentional set included congruency between the activated meaning and the target-defining color to detect the target.
