    Abstract: 工作記憶與許多認知功能都有關連，例如，閱讀理解、推理以
    及類別學習。自從10 年前COVIS 模型被提出後，研究者開始
    積極探索工作記憶與類別學習之間的關係。尤其，由於COVIS
    模型主張唯有單向度的類別規則學習（RB），才需要工作記憶
    的調控；雙向度的類別規則（II）則不需要。許多研究者都致
    力於檢驗此一說法。然而，目前所得證據卻仍然相當分歧。一
    派學者發現當工作記憶容量被擠壓時，RB 規則的學習表現會變
    差；但，II 規則的學習則不受影響。另一派學者則是指出這類
    的分離現象，很多都是由於作業難度沒控制好，或者其它混淆
    變項所引起。這些分歧的主要原因之一有可能來自於它們都是
    小樣本的實驗，以致於所觀察到的現象有可能含有極大的隨機
    誤差成份。因此，本研究採用大量尺的研究方法，以超過100
    人的受試者樣本進行實驗。
    Working memory is crucial to many aspects of
    cognition, including reading comprehension, reasoning,and categorization. Since the emergence of COVIS model \\cite{Ashby_etal_1998}, the relationship between working memory and category learning has attracted researchers‘ attention. Specifically, as induced by COVIS model, whether working memory exclusively mediates the learning of uni-dimensional categorization rule (i.e., RB) but not the learning of multi-dimensional categorization rule (i.e., II)
    becomes a major theoretical debate. Although the
    advocators for COVIS model provide evidence for the dissociation between the learning performance in RB and II conditions and the increased load of workingmemory only influences the RB performance, not the II performance, other researchers point out the possibility of the involvement of other confounding variables. Among the possible reasons for these inconsistent findings, the small sample size might be relatively paramount. Therefore, in order to get a better clarification, this study adopts a large-scale method with N > 100, each of whom were tested under 4 fully counterbalanced conditions of two difficulties and two rule types (i.e., RB and II).
