Objectives: Inferences of implicit causality are essential for understanding sentences containing interpersonal verbs. In this study, we examined the development of the comprehension of Korean interpersonal verbs of people of ages ranging from age 4 to adulthood.
Methods: In this study, we classified Korean interpersonal verbs into 3 types: agent-patient, agent-evocator, and experience-stimulus. For the comprehension task, we compared the response accuracies and reaction times for 2 types of target sentences; one type was subject causality sentences which were biased toward the subjects, and the other type was object causality sentences. After the participants were told the interpersonal verb sentences, they were instructed to choose one of the two pictures to describe the sentence.
Results: Both the response times and accuracies reflected developmental differences. Children of age 8 spent more time responding to the subject-causality type; however, their rate of accuracy was significantly higher than that of the younger groups. The data of reaction time showed no differences in the type of causality in the youngest and adult group but the older group, especially the 8-year-old children, processed the subject-causality for a longer time than object-causality sentences. The reaction times for experience-stimulus sentences were faster than the reaction times for other sentences. In addition, the performances of 8-year-old children in both reaction time and reaction accuracy for acquisition of interpersonal verbs were approaching the performance of the adults.
Conclusion: This study is special in that the developmental trajectory of interpersonal verbs is important for assessment of language language in Korean.
