Abstract: This paper suggested that distinct from different experimental schedules, a further classification of priming-type and recognising-type should be made on the most characteristic processing dissociation model (PDP). Two experiments had been made on purpose to examine the roles of discriminability of stimulus resource on the recoginsing-type experimental schedule. And also to examine some variables' (stimulus materials, attention levels and processing levels, etc.) influence upon the corrected hit probability of stimulus items in the word list 1. The result showed: Both familiarity and discriminability of stimulus resolute determined the subjects response to the exclusive examination. The use of Chinese characters as stimulus material made no difference to the experimental results.

Key words: recognising-type experimental schedule of PDP, familiarity, discriminability of stimulus resource
