To investigate relationship between syntactic parsing processes and working memory processes, first, we reviewed various approaches on sentence processing and basic experimental results about Korean syntactic processing. Then, two experiments were performed to examine processing characteristics of conjoined coordinative sentence parsing in working memory. In Experiment I, four different types of the conjoined sentence were compared by using the speeded comprehension task. Especially, we tried to decide relative explanatory power of three hypotheses such as the accessibility hypothesis, the working memory hypothesis, and the recent filler strategy. The standard type of conjoined sentence that has a subject as a coreferent showed the fastest comprehension time, In Experiment II, to verify the validity of the working memory hypothesis, two kinds of ambiguous conjoined sentence were compared by asking an ambiguous coreferent word. It was found that the results of the two experiment could not be handled by any one hypothesis. They should be explained by considering all syntactic cues of the sentence and the processing characteristic of working memory, Different parsing processes between Korean arid English were also discussed.
