The difficulty of naming for aphasia patients does not mean that the target word has been erased from the patient's memory, but it is difficult to word finding when speaking the name of the object or action presented during the conversation due to the problem of word retrieval. So, in order for aphasia patients to communicate smoothly, it is very important to evaluate the degree of naming disorder seen by aphasia patients and present appropriate stimuli(Gang, 2007). Existing aphasia research has naming implemented the task of noun naming, and research on the task of verb naming and the resulting solution rate or error type is relatively insufficient.
Therefore, this study aims to find out whether there is a difference in the Accuracy (%) in the verb naming by severity and the Accuracy (%) rate according to the number of verb arguments in each of the eight aphasia patients classified according to the severity of aphasia, and to find out the difference in the solution rate by severity after presenting semantic cue. In addition, we would like to find out the difference in the solution rate by group before and after presenting semantic cue find out which argument structure of the verb argument has a high solution rate after presenting semantic cue and find out the type of error in the verb namig by severity.
The results of this study are as follows.
First, among the three groups, the difference in the Accuracy (%) in the verb naming was the highest in the moderate to severe, followed by mild to moderate and severe.
Second, Among the three groups, the difference in the Accuracy (%) rate according to the number of arguments was in the order of 2nd verb, 1st unaccusative verb, and 3rd verb in the middle, 2nd verb, 1st unaccusative verb, and 3rd verb in the depth, and 1st unaccusative verb and 3rd verb in the same order.
Third, among the three groups, the difference in the resolution rate after presenting the semantic cue was the highest in the moderate to severe, followed by mild to moderate and severe.
Fourth, the difference in resolution rates between groups before and after the presentation of semantic cue in the three groups showed high performance after presentation of semantic cue in mild to moderate and moderate to severe, and higher performance before presentation of semantic cue in severe.
Fifth, In the three groups, the solution rate according to the number of verb arguments after presenting the semantic interpretation cue was in the order of mild to moderate to 1st unaccusative verb, moderate to severe to 3rd verb, and 2nd verb, and 3rd verb were the same in the middle, and the 3rd verb was the lowest. In severe, it appeared in the order of 1st unaccusative verb, 3rd verb, and 2nd verb.
Sixth, as for the type of error by group, intrusion errors appeared the most in mild to moderate and moderate to severe, and nonword errors appeared the most in severe.
The significance of this study is to provide important insights in the treatment of aphasia by evaluating the ability of patients to perform verb naming by aphasia severity, and to present basic data for practical improvement in aphasia treatment. In addition, the scope of the study is expanded by utilizing various samples and semantic cue types, and follow-up studies on the verb naming performance patterns of aphasia patients are needed.
