Abstract: | 過去研究基於成分拆解處理取向,主張部首做為次字彙單元,其語義在單字辨識之前即被激發處理,並對單字語義與之一致的目標字辨識產生促進作用。然而,過去研究報告的部首次字彙效果,混淆了字彙層次的鄰群效果,故有必要釐清兩者以掌握部首訊息的心理表徵與運作歷程。本研究從鄰群角度出發,透過操弄部首相同字間的字形關係與字義關係,檢驗部首做為鄰項字間共有的形、義成分對單字辨識的影響,推論部首效果所對應的處理層次。本研究採用字彙判斷作業,實驗結果發現:(1)部首鄰項字的字形訊息對目標字辨識有干擾作用,但僅限於部首在相同位置的促發配對情況。此外,部首鄰項字的形似抑制效果受到單字頻率調控,高頻字比低頻字容易受到形似干擾。(2)部首鄰項字的語義訊息對目標字辨識有促進作用。義似促進效果受到單字頻率調控,低頻字比高頻字容易受到語義訊息幫助。(3)部首鄰項促發字對目標字造成的形似抑制效果,與義似促進效果,皆未因促發字與目標字共有相同部首而有重複處理的增益作用。並且,兩作用為加成性效果,顯示兩種訊息各自獨立運作後對目標字辨識產生整合性影響。(4)在單純字彙判斷作業,相較於語義鄰項少的情況,目標字與多數部首鄰項字有共通的語義訊息時,參與者有較快的辨識反應時間。(5)抑制型的鄰群密度效果,參與者對鄰項多的目標字有較長的辨識反應時間。但只顯現於低頻目標字情況。綜合所有實驗結果,本研究認為在單字辨識時,部首鄰項字也會被激發並影響著目標字的字彙處理,部首是以鄰群形式影響單字辨識。 Underlying information processing approach, words are considered decomposed processing for recognition in which sublexical information play roles. For Chinese characters, researchers suggest that meanings of semantic radicals enhanced whole-character recognition while characters and semantic radicals share the same semantic representation (Chen & Weekes, 2004; Chen, Weekes, Peng, & Lei, 2006; Feldman & Siok, 1999a, 1999b). However, relative evidence in previous studies was confounded with neighborhood effect, and needs to be reinvestigated. Characters with an identical semantic radical are form similar to be orthographic neighbors. As a result, neighborhood characteristics should be taken into account considering recognition. This study discusses the possible role of semantic radicals through investigating neighborhood effect of form similar (with same semantic radicals) characters in lexical decision task. The main findings are: (1) an inhibitory priming effect was found in prime-target pairs that primes and targets had identical semantic radicals in same positions. And the orthographic inhibition effect was modulated by character frequency. (2) An additive effect of orthographic inhibition and semantic facilitation in radical-related prime-target pairs. Radically and semantically related primes would facilitate target recognition on one hand and inhibit on the other hand. (3) An inhibitory neighborhood density effect was found while target characters were lack of semantic facilitation from orthographic neighbors. (4) A facilitation effect was found while target characters had a large amount semantic neighbors compared to targets had few semantic neighbors. Results of this study did not provide evidence to support sublexical processing of semantic radicals especially to semantic processing in character recognition. Instead, our findings demonstrated a neighborhood effect of characters with identical semantic radicals. |
