中文摘要 | The study was conducted to investigate how far into periphery a Chinese word can be identified. In this study, Chinese words were briefly displayed in different positions either in the right or left periphery. Subjects were first required to fixate on a fixation bar appearing on the screen center, and in the meanwhile, had to identify the target word when presented in a planed peripheral position, and named the identified word later. It was found that the probability of correct recognition of a Chinese word varies as a function of visual eccentricity, word frequency, and word structure-complexity. The probabilities of correct recognition are higher when a word is presented closer to the fovea than when presented further from the fovea. The probabilities are also higher when presented words are high-frequency or low-complexity words than when they are low-frequency or high-complexity words. With the results, an estimate of how many words ( characters ) readers can identify in a single fixation during normal Chinese reading was made. In addition, possible strategies and constraints that may influence eye movement control during normal Chinese reading were suggested from the results of the study. |
英文摘要 | 本研究旨在探討中文閱讀時有效視覺界限-亦即眼睛單一次凝視駐留時所能正確辨 認的中文字的數目。 實驗時,中文字是非常短暫地( 100 毫秒)呈現在以視網膜中心而分 的左或右視覺區的不同位置上。受試者實驗時將眼睛凝視駐留在一個凝視棒上,在駐留的同 時必須注意在左或右視覺區上出現的一個中文字而加以辨認,然後受試者必須說出這個中文 字的名稱。 本研究發現眼睛單一次凝視駐留時, 中文字正確辨認的機率是視覺離心( visual eccentricity ), 字頻( word frequency ), 以及字結構複雜度( word structure-complexity )的函數。 正確辨認的機率比較高當字體被呈現在靠近視網膜中心 時,而正確辨認的機率比較低當字體被呈現在較離開視網膜中心時。正確辨認的機率也比較 高當呈現的字是高頻率字或是結構上低複雜度的字,而正確辨認的機率比較低當呈現的字是 低頻率的字或是結構上高複雜度的字。根據上述的研究結果,研究者對於中文閱讀時眼睛單 一次凝視駐留時所能正確辨認的字數提出一個估計值。此外也根據本研究結果,對於中文閱 讀時的眼球移動控制( eye movement control )有所影響的策略與限制加以推測與探討。 |
