Th is paper aimed at investigating (i) eye movement behaviour as indication of reading fluency during anaphor processing of young adults; (ii) and the relation between eye movement behaviours and Working Memory (WM) among young adults. This experiment used eye-tracking device to study the eye movements and Auditory Working Memory subtest to measure WM capacity. Tobii Eye-t racker was used to measure the movements of eyes for the participants. The results showed that young adults have similar eye movement behaviours, which were inverse typicality effect, as children. However, the score of their WC was similar to past studies whereby a larger W C capacity indicates better accessibility of resources and thus faster resolution of anaphors and antecedents. These findings were analy zed to determine the implications on the research development of eye-tracking towards students' reading fluency during anaphor processing and its relation to working memory.
