為探討漢字位置加工是否存在詞邊界效應,本研究采用掩蔽啟動詞匯決定任務和眼動追蹤技術,通過2個實驗考察了跨詞邊界和詞內漢字轉置對詞匯識別的影響。實驗均以四字詞和兩個雙字詞為靶子,對中間兩個字進行操縱(轉置或保持不變)。結果發現:靶子的注視時間(反應時)在跨詞邊界轉置條件顯著長于相同條件,在詞內轉置條件與相同條件差異不顯著。結果表明:跨詞邊界漢字轉置干擾詞匯識別,漢字位置加工存在詞邊界效應。詞切分的開始時間可能早于漢字位置加工,或二者是同時發生的。

In the present study, we endeavored to explore whether the word boundary affects Chinese character position processing in Chinese. We used four-character words(the one-word condition) and two two-character words(the two-word condition) as our targets. In Experiment 1, we used the masked priming paradigm. In Experiment 2, we embedded the targets into sentences and manipulated the displays of the targets. The display was either identical to the target word(identity condition) or had the two middle characters of the target word transposed(TC condition). The reaction times(RTs) and fixation durations on the targets in the TC condition were much longer than those in the identity condition for the two-word condition but were not significantly different for the one-word condition. These results indicate that transposing two characters across word boundaries inhibits word recognition, and the word boundary effect exists in character position processing. Word segmentation occurs at a very early stage of word recognition,before or coinciding with the character position processing.
