The purpose of this study was to examine the English l sound in an English short story produced by 16 Korean students in order to determine various allophones of the sound using acoustic visual displays and perceptual judgments. The subjects read the story in a quiet office at normal speed. Each word included the lateral sound in onset or coda positions and before a vowel of the following word. Results showed as follows: Firstly, there was a durational difference between the two major groups. Also the majority of the subjects produced the clear l regardless of the contexts. Some students produced the sound as the Korean flap or the English glide [r]. A few missing cases were also seen. The dark l was mostly produced by the subjects of English majors in coda position with a few cases before a vowel in a phrase. Visual displays using the computer analysis were very helpful in distinguishing lateral variants but sometimes perceptual process would be necessary to judge them in fast and weak production of the target word. Further studies would be desirable to test the discrepancies between the acoustical and perceptual decisions.

이 연구에서는 어머니의 자녀 양육 행동에 대한 청소년과 어머니간의 지각 차이와 청소년의 적응을 연관시켜 고찰하였다. 자료 수집은 질문지를 통해 이루어졌으며, 참여자들은 미국 동부 소도시에 거주하는 82명의 9 학년 남녀 학생과 어머니들이었다. 자료 분석 결과, 평균적으로는 어머니들이 청소년 자녀들보다 자신의 자녀 양육 행동을 더 긍정적으로 지각했다. 청소년의 적응을 어머니와의 지각 차이에 따라 살펴 본 결과, 어머니의 양육 행동을 어머니 보다 긍정적으로 지각하는 청소년들이 어머니 보다 부정적으로 지각하는 청소년 보다 문제 행동을 하는 경향이 낮았으며, 자신감은 높았다. 또한, 어머니의 양육행동을 어머니 보다 긍정적으로 지각하는 청소년들이 그렇지 못한 청소년들에 비해 어머니와 원활한 의사소통을 하는 것으로 나타났다. 이 연구의 결과들은 청소년과 어머니간의 지각 차이가 측정 상의 문제만이 아닌 청소년 발달과 연관 있는 요인임을 지적한다. 그리고, 지각 차이를 연구할 때는 그 차이의 크기 뿐 아니라 청소년과 어머니 중 어느 편의 지각이 더 부정적인지도 고려해야 한다는 점을 지적한다.

Previous studies have provided important findings on children's speech production development. They have revealed that essentially all aspects of children's speech shift toward adult-like characteristics over time. Nevertheless, few studies have examined the perceptual aspects of children's speech tokens, as perceived by naive adult listeners. To fill the gap between children's production and adults' perception, we conducted cross-sectional perceptual studies of monosyllabic words produced by children aged two to six years. Monosyllabic words in the consonant-vowel-consonant form were extracted from children's speech samples and presented aurally to five listener groups (20 listeners in total). Generally, the agreement rate between children's production of target words and adult listeners' responses increases with age. The perceptual responses to tokens produced by two-year old children induced the largest discrepancies and the responses to words produced by six years olds agreed the most. Further analyses were conducted to identify the sources of disagreement, including the types of segments and syllable structure. This study makes an important contribution to our understanding of the development and perception of children's speech across age groups.
