Abstract

This study investigated the formation and consolidation of memory following the learning of Korean Eojeols using Eojeol recognition task and an Eojeol decision task. Eojeol recognition task was designed to access episodic memory primarily, whereas the Eojeol decision task served as an index of semantic memory. In addition, we examined how lexical variables of the learned Eojeols influenced performance as a function of temoral delay. Participants performed the tasks immediately after learning and following a day of delay. The results showed that Eojeol recognition task had clear learning effects immediately after training, whereas the Eojeol decision task did not yield significant effects. This suggests that newly learned Eojeols may initially be supported by episodic memory representations. Furthermore, temporal delay significantly reduced reaction times across both tasks. However, accuracy was not significantly different before and after the delay in either task, suggesting that temporal delay alone may not be sufficient to induce stronger learning effects. Finally, in the Eojeol recognition task, the effect of temporal delay interacted with the frequency of the first syllable, indicating that lexical variables may exert different influences at early learning stages versus during consolidation.
