The time course of semantic and associative priming effects is different in an attentional blink task

Abstract

When two targets are presented using rapid serial visual presentation (RSVP) and the interval between the targets is 200-500ms, report of the second target is impaired, a phenomena known as the attentional blink (AB). This study examined the time course of semantic-only and associate-semantic priming effects during an AB task. Three RSVP experiments were conducted using targets that shared either a semantic-only or an associative-semantic relationship. The results of the three experiments demonstrated semantic-only priming effects at the shortest stimulus onset asynchronies (SOAs). Associative-semantic priming was evident at shorter and longer SOAs. This suggests that priming in an AB task is driven by conceptual overlap facilitating lexical access at short SOAs and with longer SOAs lexical access benefits from word associations links between targets.
