The aim of this study was to investigate the phenomenon of attentional blink during the recognition of compound patterns, which comprised larger (global) letters containing smaller (local) letters, appearing in rapid serial visual presentation (RSVP). Sixteen undergraduate students were first required to identify a target defined at the global or local level, and to detect a probe presented randomly at either the local or global level in a posttarget stream. When the target appeared at the local level, no attentional blink occurred for any of the probes, whether presented at the local or global level. In contrast, when the target appeared at the global level, a significant attentional blink was observed, especially for those probes presented at the local level. These results suggest an asymmetric property when switching the focus size of attention, that is, an attentional shift to the global level can be conducted easily, whereas a shift to the local level requires a greater cost.
