本研究旨在探討中文子元及調(word)的結構複雜性與眼睛對於一個詞的最佳辨識位置(OVP)對閱讀時眼睛移動控制的影響。實驗的材料是中文句子，研究者將子呈現於電視螢幕的中央，受試者一次閱讀一個目標句子。每一個目標句子都設計有一個位置臺不放置五種不同的目標詞(word)。實驗時，研究者使用眼睛移動追蹤器來觀察記錄受試者在閱讀每一個句子及句子中所包含的目標詞的閱讀時間、眼睛停落位置及形態。研究結果顯示;(a)辨識二字元詞時睛有一個最佳的辨識位置，這一個位置是在第二個字元的左半部;(b)當眼睛要移動到下一個要加以辨識的詞時，對眼睛停落來說，並沒有一個較偏愛或喜愛的停落位置，眼睛停落在詞內的每一個位置的機率沒有顯著差異;(c)眼睛要停落在複雜的詞時所產生的躍動長動(saccade length)比要停落在非複雜的詞時的躍動長短;(d)眼睛停落在複雜的詞的停落機率(fixation probability)比停落在非複雜的詞的停落機高;(e)眼睛停落在複雜的詞的停落時長(fixation duration)比停落在非複雜的詞的停落時長。這些研究結果顯示閱讀中文時眼睛的移動控制深受中文字元及詞結構複雜性的影響。

　　　　　 The Experiment was conducted to investigate how character complexity and the optimal viewing position of the eyes in a word affect eye movements in normal reading of Chinese. Subjects were required to read one sentence a time which contained a critical two-character word for the observation of the fixation pattern of the eyes. The results showed: (a) there is an optimal viewing position, at the left half of the second character, for the identification of two-character words in normal reading; (b) there is no preferred viewing position (PVP) for where the eyes are sent into a new word, with the eyes fixating equally at different positions in the words; (c) the eyes tend to generate a shorter saccade length when fixating complex words than when fixating non-complex words; (d) the eyes fixate on complex characters more than on non-complex characters, and (e) fixations on complex characters are longer than those on less complex character. The results suggest that eye movement control in Chinese reading is greatly affected by character complexity.
