漢字辨識理論模型中的部件表徵

Radical Representation in Models of Chinese Character Recognition

漢字對照於歐美研究主體的英文，可用以檢驗通用閱讀理論的適切性，其中尤以漢字「字中有字」的巢套式結構為字詞辨識理論的重要挑戰。本文旨在探討漢字辨識歷程中部件所扮演的角色，回顧並評論下列重要議題：整字與部件孰為漢字辨識的基本單元、部件表徵是否攜帶位置與表義或表音的功能、以及聲旁如何影響整字的讀音等。文末並提出部件是否必然介入漢字辨識歷程的單路徑與雙路徑模型，用以整合目前的研究證據並提供未來研究的方向。

Compared to English that are largely used as stimulus materials in developing word recognition models, Chinese characters provide the best contrast to test the adequacy of general models of word recognition. In this article, critical reviews on the role of radicals in Chinese character recognition and several important models are provided. The following issues are discussed: whether characters or radicals are the basic recognition units, what information (i.e., position or function) is carried by radicals during character recognition, and the role of phonetic radical in the pronunciation of character. In the end, a single-route model and a dual-route model as to whether radical representation is necessary for models of Chinese character recognition are proposed to serve as a theoretical framework for the evidence provided so far.
