A Psycholinguistic Behavioral Study on Noun-Verb Collocations Classified by Levels: Based on a Lexical Decision Task

Previously, selecting vocabularies was based on frequency, review of existing literature, and expert assessment. However, associative relations such as collocations were not considered. Therefore, it is necessary to quantitatively analyze a more empirical verification of the semantic network based on collocation relations. These would be confirmed through the reaction time and accuracies that appeared in performing a lexical decision task for collocations of noun-verb pairs using priming effects by native Korean speakers and Chinese Korean learners. In the results, native speakers showed statistically significant differences between unrelated words, low-frequency co-occurrences, middle-level collocations, and beginner-level collocations. However, for Chinese-speaking learners of Korean, there were differences only between collocations and non-collocations in the accuracies. In particular, high-frequency collocations showed more accurate and consistent processing patterns compared to other relation types. These suggest that teaching vocabularies using high-frequency collocations makes learners construct the semantic network more effectively and can process vocabularies most accurately and easily.
