Three experiments were carried out to elucidate the origins of the concreteness (C) effect in a lexical decision task. The first experiment was a replication of the work of Schwanenflugel et al. (1988) and Van Hell and De Groot (1998), who presented the context availability (CA) hypothesis. In this experiment CA seemed to be a dominant factor. Familiarity (FAM) was not incorporated in the ANOVA, but a regression analysis and negative correlation between C and FAM in the groups matched on CA showed that FAM could explain the disappearance of the C effect. Experiment 2 controlled FAM and revealed a C effect, although concrete and abstract words were matched on CA. Experiment 3 controlled C and FAM and revealed a CA effect. The current data emphasize the importance of controlling FAM and CA in examining the C effect in a lexical decision task and support a revised version of the dual-coding theory.
开展了三项实验以阐明词汇判断任务中具体性（C）效应的起源。第一个实验重复了施瓦嫩弗吕格尔等人（1988年）以及范·赫尔和德格鲁特（1998年）的研究，他们提出了语境可用性（CA）假说。在该实验中，CA似乎是一个主导因素。方差分析未纳入熟悉度（FAM），但在CA匹配的组中，对C和FAM进行回归分析以及负相关分析表明，FAM可以解释C效应的消失。实验2控制了FAM并揭示了C效应，尽管具体词和抽象词在CA上是匹配的。实验3控制了C和FAM并揭示了CA效应。当前数据强调了在词汇判断任务中检验C效应时控制FAM和CA的重要性，并支持双编码理论的修订版。
