采用眼动轨迹记录法结合边界呈现的实验范式,当注视点越过特定位置时,预视字则变为另一目标字,从而保证预视字只呈现在副中央凹区域。实验1自变量为预视字频率,预视字与目标字均与当前句子具有语义连贯性。实验发现,当预视字是低频时,中央凹的首次注视时间和凝视时间更短。实验2在预视字与当前句子语义不连贯的情况下进一步探讨预视字的字频对中央凹加工的效应。实验发现,预视字是高频时,中央凹的首次注视时间和凝视时间更短。然而在以区域作为数据分析的单位时,副中央凹-中央凹效应仅在首次注视时间上呈现显著。上述结果表明,副中央凹的词汇属性会对中央凹的加工产生一定的影响,但这种影响比较微弱,该结果为阅读加工理论中的并行加工理论提供了一定的支持。

英文摘要：

How much information can be acquired from a single fixation in normal reading-Whether words in a sentence are processed one by one （serially）,or two or more words are processed in parallel,is a major dispute between serial attention shift （SAS） and distributed lexical processing models （SWIFT） of eye movement control.Assessing which type of model is more consistent with empirical data has become a hot topic in research examining eye movements during reading.The main purpose of the present study was to determine how processing of characters in the parafovea affects foveal inspection time during Chinese sentence reading.The boundary paradigm （Rayner,1975） was used in two experiments designed to examine whether processing of the fixated character was affected by the frequency of the character to the right of fixation.An invisible boundary was positioned between the two characters （N and N-1）.Once the reader＇s eyes crossed the boundary,the incorrect preview of N was changed to the correct character,ensuring that the preview character was only available for parafoveal processing.In Experiment 1,30 university students were asked to read 48 sentences.There were two types of preview characters （high-or low-frequency）,both of which were congruent with the context.When the eyes crossed the invisible boundary,both previews were changed to the same target character,which was also congruent with the context.In Experiment 2,34 university students were asked to read 76 sentences.Again,the frequency of the preview character was manipulated （high or low）.Both of the two preview characters were incongruent with the sentence context,but the target character was congruent with the context.In Experiment 1,the results showed that first fixation durations and gaze durations on character n were longer with low-frequency previews than with high-frequent previews.In contrast,first fixation durations and gaze durations on character n-2 were longer in the condition where a high-frequency preview of n was being
