Models of spoken word recognition assume that words are represented as sequences of phonemes. We evaluated this assumption by examining phonemic anadromes, words that share the same phonemes but differ in their order (e.g., sub and bus). Using the visual-world paradigm, we found that listeners show more fixations to anadromes (e.g., sub when bus is the target) than to unrelated words (well) and to words that share the same vowel but not the same set of phonemes (sun). This contrasts with the predictions of existing models and suggests that words are not defined as strict sequences of phonemes.
口语识别模型假设单词是由音位序列表示的。我们通过检查音位回扫(anadromes)来验证这一假设,即共享相同音位但顺序不同的单词(例如 sub 和 bus)。使用视觉世界范式,我们发现与不相关的单词(well)和共享相同元音但不同音位集的单词(sun)相比,听者对回扫词(例如 sub 当 bus 是目标时)的注视更多。这与现有模型的预测形成对比,表明单词不是严格的音位序列定义的。
