Abstract:

This paper reports results of an AXB perceptual test investigating participants' reliance on quality and/or duration cues in perception of English tense-lax distinction in L2 Polish and Croatian learners. Croatian participants, who have phonemic vowel length distinction in their L1, rely mainly on duration as a cue in categorization. In contrast, Polish learners rely predominantly on quality in both front and back vowels, although there is no quality contrast in back vowels in Polish that would be parallel to the tenseness contrast in English. The findings do not contradict Bohn's Desensitization Hypothesis as long as one assumes that it is contrasts and not phonemes (categories) that trigger desensitization and that L1 dominant perceptual strategies may be generalized to be used for categorization of L2 categories that have no obvious counterparts in L1. We have found that learners' strategies evolve with level of proficiency. Learners improve in the use of the dominant cues. They also improve on the contribution of cues, that is, they achieve a more native-like reliance on spectral cues. No support was found for Escudero's (2000) hypothesis that all L2 learners first go through a phase of overreliance on durational cues irrespective of the phonemic contrasts of L1.

摘要：

本文报告了一项 AXB 感知测试的结果，该测试调查了参与者在 L2 波兰语和克罗地亚语学习者中对质量和/或持续时间线索的依赖，以感知英语时态-松弛差异。克罗地亚语的参与者在他们的 L1 中有音位元音长度区别，主要依靠持续时间作为分类的线索。相比之下，波兰语学习者主要依赖前元音和后元音的质量，尽管波兰语后元音的质量对比与英语中的时态对比不平行。研究结果与 Bohn 不矛盾 s 脱敏假说，只要假设触发脱敏的是对比而不是音素（类别），并且 L1 主导的知觉策略可以概括为用于 L1 中没有明显对应物的 L2 类别的分类。我们发现学习者的策略随着熟练程度的提高而发展。学习者在使用主导提示方面有所改进。他们还改进了线索的贡献，也就是说，他们实现了对光谱线索的更自然的依赖。Escudero (2000) 的假设没有得到支持，即所有 L2 学习者首先都会经历一个过度依赖持续时间线索的阶段，而不考虑 L1 的音位对比。他们还改进了线索的贡献，也就是说，他们实现了对光谱线索的更自然的依赖。Escudero (2000) 的假设没有得到支持，即所有 L2 学习者首先都会经历一个过度依赖持续时间线索的阶段，而不考虑 L1 的音位对比。他们还改进了线索的贡献，也就是说，他们实现了对光谱线索的更自然的依赖。Escudero (2000) 的假设没有得到支持，即所有 L2 学习者首先都会经历一个过度依赖持续时间线索的阶段，而不考虑 L1 的音位对比。
