两个音素监测实验的报告，检查词汇激活产生的单词包含初始，中间，或最后的发音错误。实验1表明，最小的（一个独特的功能）不匹配的初始音素产生词汇激活相对于基线控制非字，但只有当目标音素位于字偏移，而不是字内部。这一发现表明，相当多的自下而上的支持，需要推翻最初的不匹配的语音信息的抑制作用。实验2发现，没有词汇激活后，内侧不匹配，这一发现是一致的自下而上的抑制，但不一致的模型假设只有侧抑制。总之，这些发现提供了一个选择过程，其中包括自下而上的抑制作为一个主要组成部分的证据。
Two phoneme monitoring experiments are reported that examine the amount of lexical activation produced by words containing initial, medial, or final mispronunciations. Experiment 1 showed that minimal (one distinctive feature) mismatches in the initial phoneme produced lexical activation relative to a baseline control nonword, but only when the target phoneme was situated at word offset and not word-internally. This finding suggests that considerable bottom-up support is required to override the inhibitory influence of the initial mismatching phonological information. Experiment 2 revealed no lexical activation after a medial mismatch, a finding that is consistent with bottom-up inhibition, but inconsistent with models assuming only lateral inhibition. Taken together these findings provide evidence for a selection process which includes bottom-up inhibition as a major component.
