Abstract: This research is an attempt to examine how some factors,such as the frequency stimulus display, the form and nature of the stimulus, the depth of processing,the difficulty of operation and the effect of inten- tionality influences the memory of frequency. The result shows that the encoding of ferquency is not an independent and automatic processing sys tem. Some influential factors in other memory processes are also effective in changing the level of frequency estimation. The active role intentiona- lity played can be seen clearly when memory tasks are difficult and lack of effective cues for recall. Intentionality can promote, to some extent, the level of frequency estimation. The depth and amount of memory traces are two interrelative cues from which the information of fre- quency are derived. In addition, some important ideas concerning the memory of frequency are also reviewed briefly in this article.

Key words: frequency memory, intentionality, memory trace, depth of processing
