Abstract: 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.

Key words: Feeling-of-Knowing, sensibility, response bias
