Eye Movements Study On The Preview Benefit Of Word N+2 In Chinese Reading

Focuses on the point whether the frequency of the word n+1 can influence the existence of preview benefit of the word n+2 in Chinese reading,the boundary position was first studied as an independent variable,this study use boundary paradigm and two experiments of within-subject design about the influence of attention resource of the word n+1 on the preview benefit of the word n+2.The experiment1 aims to study whether the preview benefit of word n+2 can exist when the word n+1 is a low frequency word.It's a 2(boundary location: before word n+1 and word n+2)×2(preview of word n+2: identical preview and control preview)within-subject design.Experimental results show that the main effect of the boundary position on the first fixation duration and total fixation duration is not significant,but on the gaze duration,the time of position n+2 is longer than position n+1.The previewing type is significant in the first time of fixation,gaze duration,and total fixation time,showing the same previewing conditions significantly shorter than the manipulative previewing conditions.The interaction between the boundary position and the previewing type is not significant on first fixation duration and total fixation duration,but there was no significant difference on the gaze duration.The experiment2 aims to do further research about the influence of attention resource of the word n+1 on the preview benefit of the word n+2.On the basis of experiment1,wondering how much the frequency of word n+1 can influence the preview benefit of word n+2 by 2(frequency of word n+1: high frequency and low frequency)×2(preview of word n+2: identical preview and control preview)within-subject design.Experimental results show that the main effect of the word frequency on the first fixation duration,the gaze duration,total fixation duration and number of fixation is not significant;The previewing type is significant on the first time of fixation,gaze duration,and total fixation time,showing the same previewing conditions significantly shorter than the manipulative previewing conditions.The interaction between the word frequency and the previewing type is not significant on the first time of fixation,gaze duration,and total fixation time.Through the analysis of experimental results,this study draws the following conclusions:(1)In Chinese reading,the preview benefit of word n+2 exist obviously.The reader can obtain some information from the parafoveal.This partly supports the theory of parallel processing model(GAG).(2)In Chinese reading,when the preview information that was obtained from word n+2 is useful,it can improve the processing of word n+1.(3)In Chinese reading,the attention resource of word n+1 cannot influence the existence of the preview benefit of word n+2.This is to say,the frequency of word n+1 cannot influence the existence of the preview benefit of word n+2.(4)In Chinese reading,the frequency of word n+1 can influence the word n+2 parafoveal preview effect.The word n+2 parafoveal preview benefit more when the word n+1 is a high frequency word than when the word n+1 is a low frequency word on the indicators of FFD and GD.
