The Decision Of Saccadic Target Selection In Chinese Reading:the Interactive Way Of Visual And Lexical Information

The selection of target is one of the basic issues of eye movement control during reading.In Chinese reading,the complexity of character would influence not only fixation duration but also landing position.Otherwise,the processing difficulty of target word would have an effect on the selection of target.The present paper would discuss whether the influence of the numbers of strokes of Chinese characters on landing position was caused by visual complexity,or processing complexity which was resulted in visual complexity.In order to eliminate the effect of lexical information,such as lexical frequency,phonotactics,or lexical status,this study introduced "Landolt" paradigm.49 participants who aged from 18 to 25 were recruited from Tianjin Normal University.The independent variable had two levels(including lexical information or not).Linear mixed-effects models(LMMS)which were built for experimental data were fitted using the lme4 package and p-values were estimated by lmer Test package in R.The results were showed as follows.(1)Having lexical information or not influenced the locations of initial fixations and single fixations.In additions,it would have an effect on the skip rate,refixation probabilities and average forward-saccade length.(2)The influence of the numbers of strokes of Chinese characters on landing position had relationship with not only visual complexity,but also the complexity of cognitive processing.(3)According to the theory of primary oculomotor control,the results supported that Chinese readers used "strategy-tactics" to guide their eye movement during reading.
