Bottom Line: In this study, we employed varying connections between T1 and T2 and examined how these connections modulate the AB effect.We found that the strongest AB was observed when the two Chinese characters were completely unrelated, while the AB was reduced when T1 and T2 were phonologically, orthographically or semantically related and was almost completely eliminated when T1 and T2 were united in a lexical phrase.The order of activation between Chinese characters was identified as follows: (a) lexical phrases, (b) semantic connection, (c) morphological connection, (d) phonological connection and (e) unrelated words.

ABSTRACT
The ability to identify the second of two targets (T2) is impaired if that target is presented less than ∼500 ms after the first (T1). This transient deficit is known as attentional blink (AB). Previous studies have suggested that the magnitude of the AB effect can be modulated by manipulating the allocation of attentional resources to T1 or T2. However, few experiments have used Chinese characters and words to explore this phenomenon. The existence of lexical, semantic, phonological and morphological connections between Chinese characters has been well established, and understanding these connections may improve our knowledge of reading Chinese. In this study, we employed varying connections between T1 and T2 and examined how these connections modulate the AB effect. We found that the strongest AB was observed when the two Chinese characters were completely unrelated, while the AB was reduced when T1 and T2 were phonologically, orthographically or semantically related and was almost completely eliminated when T1 and T2 were united in a lexical phrase. The order of activation between Chinese characters was identified as follows: (a) lexical phrases, (b) semantic connection, (c) morphological connection, (d) phonological connection and (e) unrelated words.

pone-0104626-g005: Mean accuracy in identifying T2 in the single-task experiment.The error bars represent the standard error.

Mentions: Figure 5 shows the subjects’ mean accuracy in identifying T2 during the single-task experiment at all SOAs in each of the five categories. The mean performance in identifying T2 under unrelated, phonological, morphological, semantic and phrase conditions were 78.25%, 94.69%, 95.52%, 95.72%, and 96.46%, respectively. A two-way ANOVA showed that there was no significant main effect of temporal lag (F1(7,152) = 1.903, p = 0.116; F2(7,1192) = 1.389, p = 0.236). The AB effect was absent in the single-task experiment, which is consistent with previous reports indicating that awareness of T1 is necessary for its occurrence.
