本文從「黨派思維結構體」的概念，來說明選民可能應用作爲處理選舉情境訊息的一種心理機制，並從政治認知的角度來看選民的「政治練達水平」，並進一步據以分析選民的投票行爲。首先，從本文關於黨派思維結構體的分析中，我們發現：雖然臺灣缺乏深厚的政黨政治的文化與傳統，但在競爭性政黨政治萌芽的民主轉型過程中，隨著選舉與政黨競爭的規模擴大，選民的腦海中已經逐漸發展出「黨派思維結構體」，而用之於政治性 (尤其是黨派性) 訊息處理的思考與推理上。其次，選民應用黨派思維結構體的程度，與他們的政黨政治價值取向、政黨認同、政黨印象及政治練逹水平等，均具有顯著的影響關係。第三、選民的黨派思維結構體應用情形，對黨派投票抉擇與投票取向，雖没有直接的影響作用，但透過影響黨派的心理特徵，而具有間接與居中的影響效果。第四、對政治練逹水平的探討，則有助於了解選民投票取向的主要差異所在；政治練達水平以政見議題投票的選民爲最高，政黨取向投票的選民居次，再次是候選人取向的投票，而以人際及社會網絡投票的選民爲最低。總之，黨派思維結構體與政治練達水平，有助於我們了解選民在面對選舉情境中充滿黨派的政治訊息時，究竟依賴何種政治思考與推理上的「啓發｣ 或判斷捷徑，以作成投票行動的選擇。

This essay adopts the concepts of "partisan schema" and "level of political sophistication" to explore how voters process voting cues in elections. Along with the emerging of opposition parties in Taiwan's de­mocratization process, not only have elections become more competitive among parties but voters have also been imbued with more partisanship since the 1980s. There has been a weak partisanship in Taiwan, a Con­fucian society with one-party dominant system. Nevertheless Taiwanese voters have increasingly processed voting cues and cast their votes by their party preferences in post-authoritarian elections. Based on analyz­ing a survey data of the Second Legislative Yuan election, it is found first that sex and education are predictor variables of voters' use of partisan schema and their levels of political sophistication. Secondly, both the use of partisan schema and the level of sophistication are found correlated with the strength of party preference and support, and they are also the two most significant factors in shaping of individuals' voting-orientations and partisan vote-choices. Findings on voters' use of partisan schema and the level of sophistication would shed light on our understanding of Taiwanese voters' shortcut or heuristics in political reasoning and vote­ choice making.
