Abstract

A wh-phrase positioned in an embedded clause can be interpreted as having a matrix scope if the sentence is produced with proper prosodic structures such as the wh-intonation. In a previous experiment, a sentence with a wh-phrase in an embedded clause was given to 40 speakers of Gyeongsang Korean. A script containing the sentence was provided to induce a matrix scope interpretation for the wh-phrase. These 40 utterances were prepared as stimuli for a perception test to verify whether the wh-phrases in the stimuli were perceived as having matrix scopes. Each utterance was played thrice to 24 subjects. The results showed that more than half of the 72 responses indicated a preference for an embedded scope rather than a matrix scope in 20 of the utterances. A multiple linear regression analysis showed that the matrix scope responses were best predicted by the magnitude of the pitch prominence in a prosodic word consisting of an embedded verb and a complementizer. The pitch prominence was calculated by subtracting the fundamental frequency (F0) at the right edge of the prosodic word from the peak F0 in the same prosodic word. The smaller the magnitude, the more matrix responses there were. These results suggest that the categorical perception of wh-scopes is based on the magnitude of pitch prominence.

내포문에 위치한 의문사 구는 의문사 억양으로 발화되었을 경우 모문의 작용역으로 해석되는 것으로 알려져 있다. 40명의 경상 방언 화자가 모문 작용역으로 해석되는 문맥 속에서 발화한 동일 문장 발화를 자극으로 하여, 그 작용역을 판단하는 지각 실험이 24명의 경상 방언 화자를 대상으로 이루어졌다. 자극당 3회 청취로, 문장당 72개 응답이 수집되었으며, 40개 중 20개의 자극에서 36회 이상의 내포문 작용역 응답이 나타났다. 이는 경상 방언에서 명시적으로 의문사의 작용역을 표시하는 종결어미가 있음에도 불구하고 적절한 의문사 억양으로 발화하지 못하는 화자가 다수 있음을 보여준다. 다중 회귀 분석을 통해 모문 작용역 응답을 가장 잘 예측하는 운율 단서는 내포 동사와 보문소가 나타나는 어절의 돋들림 크기로, 해당 어절의 fundamental frequency(F0) 정점에서 보문소에 나타난 F0값을 차감한 수치로 계산되며, 이 돋들림이 크면 클수록 내포문 작용역으로 판단하는 음의 상관관계를 가진 것으로 나타났다. 이처럼 의문사 작용역은 내포문 동사와 보문소가 있는 어절의 돋들림 크기에 기반한 범주적 인지로 나타나며 인지의 경곗값은 실험 참가자에 따라 매우 다르게, 큰 차이를 보이는 결과로 나타났다.
