在六个实验中，我们探索了双音素概率和词汇邻域密度如何影响听者对嵌入非单词序列的元音的分类。我们发现每一个都有独立的影响。听众改变了语音连续体的分类，以创造更高的概率序列，即使在邻里密度受到控制的情况下也是如此。类似地，即使在控制双音素概率的情况下，听者也会改变分类，从更密集的邻域中创建一个非单词。接下来，使用视觉世界的眼球跟踪任务，我们确定双音素概率信息在知觉中被听者迅速使用。相反，任务的复杂性和刺激中的无关变异性会干扰邻域密度效应。这些结果支持这样一个模型，即双音素概率和邻域密度都独立地影响单词识别，但在加工的早期只观察到双音素概率效应。
In six experiments we explored how biphone probability and lexical neighborhood density influence listeners’ categorization of vowels embedded in nonword sequences. We found independent effects of each. Listeners shifted categorization of a phonetic continuum to create a higher probability sequence, even when neighborhood density was controlled. Similarly, listeners shifted categorization to create a nonword from a denser neighborhood, even when biphone probability was controlled. Next, using a visual world eye-tracking task, we determined that biphone probability information is used rapidly by listeners in perception. In contrast, task complexity and irrelevant variability in the stimuli interfere with neighborhood density effects. These results support a model in which both biphone probability and neighborhood density independently affect word recognition, but only biphone probability effects are observed early in processing.
