中央凹加工负荷与副中央凹信息在汉语阅读眼跳目标选择中的作用

研究探讨汉语读者选择眼跳目标时, 中央凹注视词的加工负荷是否影响副中央凹获取信息量, 进而调节随后的眼跳长度。采用眼动追踪技术, 操纵了中央凹注视词的词频(高频、低频)和副中央凹词的笔画数(多笔画、少笔画)。结果发现：从中央凹词到副中央凹少笔画词的眼跳长度显著地长于到多笔画词的, 且这种笔画数效应并不受中央凹加工负荷的调节; 从高频中央凹词到副中央凹词的眼跳长度显著地长于低频词的。在本实验条件下结果提示：中央凹加工负荷在眼跳目标选择中的作用不是通过调节副中央凹获取信息量的多少来实现的。

Influence of the frequency of fixated words and the number of strokes of parafoveal words on saccadic target selection in Chinese reading

In alphabetic languages, such as English, the spaces between words are one kind of cue of visual word segmentation that guides the reader in selecting the word center as the saccadic target. Previous studies have shown that in English reading, such visual word boundaries can be extracted from parafoveal vision. However, no visual word boundary serves as a saccadic target for selection in Chinese reading. Most recently, several researchers have claimed that Chinese readers adjust their saccade length to accommodate lexical processing, rather than moving their eyes to specific saccadic targets. The properties of fixated words affect the subsequent saccadic target selection. For example, the saccade length is longer for high- than for low-frequency words. Moreover, parafoveal processing also has an important influence on the modulation of saccade length. Some researchers have nonetheless found that the load of fixated word processing modulates the processing of parafoveal words, where readers then adjust the selection of the next saccade target, though several studies have failed to find an interaction between the fixated word and foveal and parafoveal processing
