C-CAT（Character-Component Analysis Toolkit）是一個輔助心理學者探討中文閱讀歷程時，根據中文字或中文字部件的特性，設計實驗材料的電腦軟體（Lo & Hue, 2008 ）。本研究旨在擴充並改進C-CAT 處理中文字及其部件的性能。這個增進版軟體（C-CAT2 ）擴充了原本的文字處理功能，使其不但能夠分析正體中文字外，也能夠分析簡體中文字。除此之外，C-CAT2 也容許使用者根據研究的需求，輸入自訂的字頻常模。本研究也邀請了一組大學生，請其將200 個中文字拆解為部件，然後再根據拆解的結果，修正軟體內建的拆字規則，使得該規則更接近一般中文讀者對於中文字組成部件的看法。

The aim of this work was to upgrade C-CAT (Character-Component Analysis Toolkit) which was designed to assist researchers in constructing experimental materials using Chinese characters (Lo & Hue, 2008). The new features built in the new version of the software (C-CAT2) include (1) an user interface which can display traditional and simplified Chinese and English, (2) a frequency norm of simplified Chinese characters used in the mainland China, and (3) a module which allows a user to incorporate any character frequency norm into the software. Moreover, a task of decomposing Chinese characters into constructing components was designed, and a group of college students were asked to perform the task. The way that the participants decomposed the stimulus characters was analyzed, and used to construct character decomposing rules in C-CAT2.
