This article examines the influence of gradient foreign accentedness on lexical competition during spoken word recognition. Using native and Mandarin-accented English words ranging in degree of foreign accentedness, we investigate the effect of increased accentedness on (a) the size of the competitor space and (b) the strength and duration of competitor activation. Here, we analyze the number of misperceptions in a transcription task, as well as the time course of competitor activation in a Visual World Paradigm eye-tracking task. The transcription data show that as accentedness increases, the number of unique misperceptions increases. This indicates that greater accent strength induces the activation of many additional competitors within the competition space relative to native speech. The eye-tracking data further show that, as accentedness increases, looks to competitors (not produced in the transcription …
