The authors examined the role of intermediate, sublexical representations in spoken word perception. In particular, they tested whether flaps, which are neutralized allophones of intervocalic /t/s and /d/s, map onto their underlying phonemic counterparts. In 2 shadowing tasks, the authors found that flaps primed their carefully articulated counterparts, and vice versa. Because none of the flapped stimuli were lexically ambiguous (e.g., between rater and raider), these results provide evidence that such priming is sublexically mediated. Therefore, the current study provides further insights into when underlying form-based representations are activated during spoken word processing. In particular, the authors argue that phonological ambiguity, inherent in their flapped stimuli, is one of the conditions leading to the activation of underlying representations.
作者们研究了中间层、次词汇表征在口语单词感知中的作用。具体而言，他们测试了闪音（即词中/t/和/d/的中性异音）是否映射到其潜在的音位对应形式。在两项跟读任务中，作者发现闪音能启动其清晰发音的对应形式，反之亦然。由于所有含闪音的刺激在词汇层面都不存在歧义（例如，在rater和raider之间不存在歧义），这些结果表明这种启动是由次词汇介导的。因此，本研究为口语单词处理过程中何时激活基于底层形式的表征提供了进一步的见解。具体而言，作者认为含闪音的刺激中固有的语音歧义是导致激活底层表征的条件之一。
