“知道感”任务中的图片和字词的感受性和判断标准

该实验考察了在“知道感”（FOK）任务中的字词和图片的感受性和判断标准的差异。实验运用Hart的“回忆—FOK判断—再认”（RJR）范式，用字词和图片作为刺激材料，采用两种不同的加工水平，并根据信号检测论中的评价法对结果进行分析，结果表明：在知道感任务中，只有在线索回忆正确百分率和FOK判断等级上表现出了图片优势效应，而再认正确率和FOK准确性则没有图片优势；而且，不论是深加工还是浅加工，被试对字词和图片的感受性都没有显著性差异，但判断标准的变化较为复杂，且受加工水平的影响较大，显示出图片优势效应的产生与被试的反应偏向有关。

SENSIBILITY AND RESPONSE BIAS OF WORDS AND PICTURES IN FEELING-OF-KNOWING

The experiment explored the sensibility and response bias of words and pictures in Feeling-of-Knowing task. The Recall- Judgement Recognition paradigm recommended by Hart was used, and there were pictures or words as stimuli, and two levels of processing were manipulated, this task was like confidence rating method of Signal Detect Theory (SDT)U. The data were analyzed in terms of SDT.The results suggested that there was no significant difference on sensibility between words and pictures,no matter whether LOP was shallow or deep, but their β values were varied differetly and affected by the level of processing.
