对FOK的线索熟悉性假说的重新检验

EXAMINING OF FOK'S CUE-FAMILIARITY HEURISTIC

本研究的主要目的，在于对ＦＯＫ的线索熟悉性假说进行重新检验。研究发现：如果采用１×２设计而不是原来的１×４设计并且增大处理间的对比力度的话，就可以观察到某些原来不能被观察到的关键性差异，而这些差异是ＥＯＫ的线索熟悉性假说所不能解释的。这一结果提示我们，ＦＯＫ判断的决定因素不仅在于线索熟悉性或目标熟悉性，而且也在于线索一目标之间的联结强度。

The cue-familiarity heuristic of FOK was examined in this study. The experiments were carried out on the basis of Metcalfe's study (Metcalfe, et al., 1993) which was considered as evidence in support of cue-familiarity hypothesis. The result of the experiment showed that, were 1×2 design (not 1×4 design in Metcalfe's study) adopted, a critical difference that couldn't be attributed to cue familiarity was observed. The result implied that,it is not only the cue familiarity or target accessibility but also the cue-target association that underlies the judgments of FOK.
