Abstract

The repetition effect has been studied widely in the studies on concept formation and lexical formation for uncovering the nature of lexical structure and process, as well as semantic priming effect. This study suggested some constraints of two existing theories, episodic theory and lexical access theory, through examining their assumptions and proposed the dual theory as alternative and testified its assumptions. Experiment 1-a and 1-b was conducted to see how the facilitatory effect of repetition was dampening out as the lags of item repetition was increased. Results showed statistically significant repetition effects of even nonwords at lag 10 conditions opposed to assumptions of lexical access theory, but episodic theory also couldn't explain no decrement in the repetition effects of words and nonwords even though their episodic context is largely changed as the lags is increased. Based on these results. Experiment 2 was planned to test assumptions of the dual approach proposed were and two existing theories by manipulating the number of repetition and semantic relations of stimulus pair as SOA conditions were changed. Experiment 2 accepted the dual approach as the best model of explaining it's results. In conclusion. the repetition effect is not depended on episodic context involved in repeated stimulus or on its lexical structure itself, but the product of interactional facilitation of episodic codes and semantic codes.
