한자어 형태소 인식력의 개인차가 형태소 점화 효과에 미치는 영향 = Individual differences in the morphological decomposition of Hanja words

다국어 초록 (Multilingual Abstract)

The present study investigated individual differences in morphological priming using Hanja compound words as stimuli. Participants were divided into high and low MA groups, according to the morphological awareness (MA) score. Morphological relation between prime and target was manipulated as identical, different, pseudo, or unrelated. Participants performed the primed lexical decision task with primes masked. The results showed that morphological priming effects differed according to morphological awareness. Facilitatory priming effect was only significant for the high-MA group, suggesting that the representation and processing of Hanja compounds might be different among individuals with varied morphological knowledge. The results from the high-MA group are consistent with the semantic-morphological decomposition hypothesis. Based on the results, the structure and access of the Korean mental lexicon were discussed in relation to individual difference.

형태소 점화 효과는 단어 재인에 형태소 분리가 필수적이라는 주장을 지지하는 현상이다. 영어를 비롯한 많은 언어에서 형태소 점화 효과가 보고되었지만 한글 표기된 한자합성어에 대해서는 수렴적 결과가 관찰되지 않았다. 본 연구는 형태소 인식력의 개인차가 형태소 점화 효과에 영향을 줄 것이라 가정하고, 형태소 인식력에 따라 참가자 집단을 나누어 차폐점화 어휘 판단 실험을 실시하였다. 점화어와 표적어 사이의 형태소 관계는 동일, 상이, 유사, 무관련으로 조작하였다. 실험 결과, 개인의 형태소 인식력에 따라 형태소 점화 효과에 차이가 나타났다. 형태소 인식력이 높은 집단에서만 촉진적 점화 효과가 나타났다. 이는 선행 연구들에서 한국어 한자 형태소 점화효과가 일관적이지 못한 이유가 형태소 인식력과 같은 개인차 변인의 영향 때문일 가능성을 시사한다. 본 연구 결과를 토대로 한국어 심성어휘집의 구조와 검색에서의 개인차, 형태소 분리의 메커니즘 등에 대해 논의하였다.
