摘　　要：为探讨汉语阅读中副中央凹预视加工在眼跳目标选择中的作用,本研究使用了边界范式,边界位于双字词(词N)后,操纵了副中央凹中双字词首字(N+1)与尾字(N+2)的预视类型,分别为能够提供有效预视信息的目标预视与不能提供有效预视信息的假字预视。结果发现:在从前目标词到目标词的眼跳长度上,字N+1目标预视下的眼跳长度显著地长于假字预视;当字N+1为目标预视时,字N+2目标预视下从前目标词到目标词的眼跳长度显著地长于假字预视,而当字N+1为假字预视时,字N+2的预视类型并不对从前目标词到目标词上的眼跳长度产生显著影响。结果表明,副中央凹的加工影响眼跳目标的选择,副中央凹中字N+1与字N+2的预视加工均会影响眼跳目标选择,字N+2的预视加工对眼跳目标选择的影响受字N+1预视加工负荷的调节。Whether both the processing of character N＋1 and character N＋2 in parafoveal affects the target selection during Chinese reading or not is still unknown. In current study, the boundary paradigm （Rayner, 1975） was used to investigate this question, the previews of character N＋1 and character N＋2 which are belonged to a two-character word were manipulated, identical character or pseudocharacter were used as these two kind of previews. Results showed that fixation durations on target word were significantly shorter when the preview of character N＋1I was identical than when it was a pseudocharacter, the same pattern appeared when both of the previews of character N＋I and character N＋2 were identical, compared to the the previews of character N＋2 was pseudocharacter. The length of the outgoing saccade from the pretarget to the target region was significantly longer when the preview of character N＋1 was identical compared to when it was a pseudocharacter. And when the preview of character N＋1 was identical, the length of the outgoing saccade from the pretarget to the target region was significantly longer when the preview of character N＋2 was identical compared to when it was a pseudocharacter. However, changing previews of character N＋2 had no influence on the outgoing saccade when the preview of character N＋1 was a pseudocharacter. The results indicated that character N＋1 and character N＋2 were preproeessed in the parafoveal before they were fixated. Parafoveal processing of character N＋1 modulated the saccade target selection. The effect of parafoveal processing of character N＋2 on saccade target selection is modulated by the processing load of character N＋1.
