| Human observers possess the remarkable ability to report a visual target even when it is embedded in a rapid serial visual presentation (RSVP) stream of spatially overlapping distractors. However, when two such targets must be reported (conventionally, T1 and T2), report of T2 is severely impaired if it is presented within approximately 500 ms of T1. This transient deficit is known as the attentional blink (AB; Raymond et al., 1992). A number of studies provided evidences that the magnitude of the AB effect can be modulated by manipulating the allocation of attentional resources to the T1 or T2. But little experiments were conducted with Chinese characters and words. As we know, there are complicated connections between Chinese characters. Therefore, Chinese characters are good cases to study the relationship of T1 and T2. At issue in the present work was how phonologic, morphological, semantic and lexical connections between Chinese characters modulate AB effect. Our results showed that strong AB was investigated when T1 and T2 were irrelative Chinese characters. However, gradual attenuation of the AB was observed with two phonologic, morphological and semantic Chinese characters. No AB effect was found any more when T1 and T2 were two lexical words. |
