Abstract:
The purpose of the study was to investigate the effects of verb argument complexity on verb production in individuals with aphasia using a verb-final language. The verb-argument complexity was examined by the number of arguments (1-, 2-, and 3-place) and the types of arguments (unaccusative vs. unergative comparisons). Fifteen Korean-speaking individuals with aphasia and 16 normal controls participated in the study. A confrontation naming task was used to elicit verb production with a total of 36 items for each verb type (1-place unergative, 1-place unaccusative, 2-place, and 3-place verbs). Individuals with aphasia presented lower mean percentage correctness in 3-place than in 1-place verbs, and showed differentially greater difficulties with unaccusative constructions than with unergative verbs, compared to the control group. The effects of verb-argument complexity were clearly observed in Korean-speaking individuals with aphasia. The effects of the number of arguments were observed most clearly in Broca's and Wernicke's types of aphasia and individuals with lower overall aphasia severity. The effects of Korean unaccusativity manifested across aphasia groups. General patterns of verb-argument complexity in Korean were consistent with previous findings in English.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
