다국어 초록 (Multilingual Abstract)

Purpose: In order to use honorific speech properly, it is needed to understand and apply social convention and make a proper judgment on the object of conversation. FTD (frontotemporal dementia) causes personality change, disinhibition, and deterioration of judgment that gradually develop due to the damage to the frontal lobe. The purpose of this study is to understand honorific speech in patients with FTD and grasp their expressional characteristics through a comparison with NE (normal elderly), and then examine the relationship with general cognitive functions through a comparison with those with AD (Alzheimer"s dementia). Methods: A total of 45 subjects (FTD group: 5, AD group: 20, NE group: 20) were made to respond to 20 items of expression task and 30 items of receptive task related to honorific speech produced by the researcher. In order to investigate the characteristics of correct responses and reaction time, their performance was measured with a software program. Results: The FTD group showed significantly lower performance than the AD group and the NE group in both tasks. Conclusion: Due to the damage to the orbitofrontal area of the frontal lobe, patients with FTD show simplification of thoughts and the symptom of disinhibition, which lead to difficulties in observing social manners, improper words and actions, and deterioration of social interaction. This result indicates that it should be hard for them to use honorific speech properly. In addition, it is thought that, due to the damage to the dorsolateral area of the frontal lobe, they would lack language processing abilities, which could make them have difficulties in using final/prefinal endings, postpositions, and words needed for honorific speech.
