词汇识别转移被用作音素识别任务中语音处理的衡量标准（WF Ganong，1980）。单词识别的交互式（自下而上和自上而下）模型通过声称词汇知识反馈到词汇前水平并帮助语音处理来解释这种转变。自主模型（仅自下而上）认为这种转变是通过其他方式和在处理的后期阶段产生的。通过使用检测理论分析程序来测量音素处理中的感知变化，研究了词汇转换的轨迹。实验 1 和 3 中话语的词汇状态（单词-非单词）有所不同，并且被发现会影响音素处理。在实验 2 中，后知觉操纵的影响（金钱回报）并未出现在检测理论分析中。讨论了结果对两类模型的影响。
The lexical identification shift is used as a measure of speech processing in the phoneme identification task (WF Ganong, 1980). Interactive (bottom-up and top-down) models of word recognition account for the shift by claiming that lexical knowledge feeds back to a prelexical level and aids speech processing. Autonomous models (bottom-up only) maintain that the shift arises by other means and at later stages of processing. The locus of the lexical shift was investigated by using detection theory analysis procedures to measure perceptual changes in phoneme processing. Lexical status (word–nonword) of the utterance was varied in Experiments 1 and 3 and was found to influence phoneme processing. In Experiment 2 the effects of a postperceptual manipulation, monetary payoff, did not show up in the detection theory analysis. Implications of the results for both classes of models are discussed.
