Two experiments，respectively experimented in the situations of a single cue and a variety of cues， were done to investigate the influence of material factory and number of repetitions on the grade and the accuracy of the EOL judgment. Experiment 1 probed into influence of word frequency or relatedness of materials on EOL by experiment 1.1 and experiment 1.2. Experiment 2 featured two independent variables—relatedness of materials (high and low) and number of repetitions (one or three) — manipulated within participants. Sixty college students took part in this experiment. The grade of EOL judgment was predicted recall. The accuracy of EOL judgment was the difference between predicted recall and actual recall. The results suggested that (1) frequency of words and relatedness of pair words had a significant main effect on the grade of EOL. (2) The accuracy of EOL was significantly lower high frequency pairwords than low frequency pairwords, and low relatedness pairwords than high relatedness pairwords. (3) Word frequency affected predicted but not actual memory. Relatedness pairwords affected both predicted and actual memory. (4) Number of study trials affected actual memory but scarcely affected predicted memory. The accuracy of EOL was significantly lower following three than following one study trials. Conclusion: (1) The influence of material factors on the grade and the accuracy of the EOL judgment were relatively stable. (2) Frequency of words and relatedness of pair words affected the accuracy of EOL judgment by different paths. (3) Number of study trials had no a significant main effect on the grade of the EOL. (4)This result suggested UWP effect occurred in Easy of Learning Judgment.
