The Limits of Attention

The visual attentional blink (AB) effect represents a limit in the speed with which visual targets—which are vulnerable to masking — can be consolidated into working memory or awareness: a second target may be lost while queuing for access to the consolidation process. This chapter reviews studies that show a clear dissociation between AB and task-switching deficits, consistent with complementary findings of Allport and Hsieh on criterion shifting in rapid serial visual processing (RSVP) target search. The evidence suggests that there are multiple bottlenecks in processing that individually or together limit performance when two target stimuli must be processed within a brief space of time.

Keywords:   attentional blink, task switching, rapid serial visual processing, memory, awareness, dual-task performance
