On segmental representations in second language phonology: A perceptual account

Abstract

The extent to which exposure to new phonemic contrasts (i.e. contrasts that are present in the L2 but not in the L1) will lead to the creation of a new phonemic category in L2 speakers, as well as the phonological nature of these categories, remains an open question insofar as there is no consensus on whether acquiring a new contrast would result in abstract, phoneme-like categories, or if they belong to a less abstract level of representation. This work explores the perception of the /ɑ/–/ʌ/ contrast (cop – cup) in American English by Spanish speakers of L2 English through a discrimination task. The results show that while the interlanguage state of less experienced learners is best described as a case of single-category assimilation, the interlanguage state achieved by advanced learners is not a full phonemic split, despite the increased sensitivity to otherwise within-category perceptual cues; rather, it seems that while the ability to perceive differences is not affected, the ability to create a new phonemic representation is impaired.
