双字词整词加工与词素加工在眼跳目标选择中的作用

为探讨整词与词素加工在眼跳目标选择中的作用，本研究采用眼动追踪技术，实验1操纵了目标词的词频（高频、低频）和目标词首字字频（高频、低频）；实验2操纵了目标词的词频（高频、低频）和尾字字频（高频、低频）。结果发现：首字字频不影响眼跳目标选择。尾字字频影响眼跳目标选择，当目标词为低频词时，高频尾字条件下从前目标词到目标词的眼跳长度显著地短于低频字条件；当目标词向前眼跳从尾字发出且目标词为低频词时，高频尾字下的眼跳长度显著地长于低频条件。词频影响眼跳目标选择，高频词条件下跳进和跳出目标词的眼跳长度均长于低频词条件。结果表明整词与尾字词素的加工负荷影响随后的眼跳计划，加工负荷越低随后所计划的眼跳长度越长，尾字词素的加工受整词加工的调节，整词与词素加工以混合表征的方式影响眼动控制。

The Processing of Morpheme and Lexical of two-character Affects the Selection of Saccade Target During Chinese Reading

In two experiments, we investigated whether character processing affect the saccade target selection in Chinese reading. In Experiment 1, we manipulate the frequency of target word and the initial character of the word. In Experiment 2, we manipulate the frequency of target word and the second character of the word. These results indicate that when target words were low frequency, the incoming saccade lengths were longer on words with low frequency second character than on words with high frequency second character. In addition, When the progressive saccade that was launched from the second character and the target word is a low-frequency words, the length of outgoing saccade were longer on words with high frequency second character than on words with low frequency second character. The properties of words in a fixated region not only affect the saccade target selection but the fixation time. The incoming and outgoing saccade lengths were longer on words with high frequency than on words with low frequency. These findings suggest that the processing of characters and word affects the eye movement control, but the role of the characters is influenced by word processing. The strategy for saccade target selection in Chinese reading is conducted in the way of combination word and character.
