초록
The present study explored whether the Perceptual Assimilation Model (PAM)’s predictions on the perceptual assimilation-discrimination relationship in non-native phonetic perception can be extended to affricate-fricative manner perception. Korean listeners were tested with English affricate-fricative /tʃa/-/sa/, /tʃa/-/ʃa/, /dʒa/-/za/ and /dʒa/-/ʒa/ contrasts in a native language assimilation task and an AX discrimination task. Both /tʃa/-/sa/ and /tʃa/-/ʃa/ yielded two-category assimilations and were discriminated very well, whereas /dʒa/-/za/ and /dʒa/-/ʒa/ yielded category-goodness and single-category assimilation, respectively, and both were poorly discriminated. These findings generally support the PAM’s predictions. One exception was /dʒa/-/za/, suggesting that assimilation overlap between non-native phones may predict the degree of difficulty that listeners have in discriminating a non-native contrast. Additionally, results showed that perception of same pairs is shaped by perceptual assimilation patterns.
Abstract
The present study explored whether the Perceptual Assimilation Model (PAM)’s predictions on the perceptual assimilation-discrimination relationship in non-native phonetic perception can be extended to affricate-fricative manner perception. Korean listeners were tested with English affricate-fricative /tʃa/-/sa/, /tʃa/-/ʃa/, /dʒa/-/za/ and /dʒa/-/ʒa/ contrasts in a native language assimilation task and an AX discrimination task. Both /tʃa/-/sa/ and /tʃa/-/ʃa/ yielded two-category assimilations and were discriminated very well, whereas /dʒa/-/za/ and /dʒa/-/ʒa/ yielded category-goodness and single-category assimilation, respectively, and both were poorly discriminated. These findings generally support the PAM’s predictions. One exception was /dʒa/-/za/, suggesting that assimilation overlap between non-native phones may predict the degree of difficulty that listeners have in discriminating a non-native contrast. Additionally, results showed that perception of same pairs is shaped by perceptual assimilation patterns.
