Evidence from priming and lexical decision tasks suggests that nonwords created by transposing adjacent letter pairs (TL nonwords) are very effective in activating lexical representations of their base words, because the process of orthographic matching tolerates minor changes in letter position. However, this account disregards the possible role of sublexical processing in reading. TL nonwords are perceptually ambiguous, with lexical and sublexical processing giving rise to conflicting interpretations. The consequences of this ambiguity were investigated in a lexical decision experiment with primes that were either high or low bigram frequency TL versions of target words. Priming effects were much larger for low BF primes (e.g., pucnh-PUNCH) than for high BF primes (e.g., panit-PAINT). This finding is interpreted as evidence that lexical activation can be inhibited by competing output resulting from sublexical processing of TL letter string. We conclude that phonological processing is an important determinant of responses to TL stimuli, and we consider how this interpretation might be accommodated within the dual-route cascaded (DRC) model of word recognition.
来自启动和词汇判断任务的证据表明，通过颠倒相邻字母对而创建的非单词（转置字母非单词，TL非单词）在激活其基础单词的词汇表征方面非常有效，因为正字法匹配过程容忍字母位置的微小变化。然而，这种解释忽略了次词汇加工在阅读中可能发挥的作用。TL非单词在感知上具有歧义性，词汇加工和次词汇加工会产生相互冲突的解释。在一项词汇判断实验中，研究了这种歧义性的后果，实验中的启动词是目标单词的高双字母频率或低双字母频率的TL版本。低双字母频率启动词（例如，pucnh - PUNCH）的启动效应比高双字母频率启动词（例如，panit - PAINT）大得多。这一发现被解释为证据，表明词汇激活会受到TL字母串次词汇加工产生的竞争输出的抑制。我们得出结论，语音加工是对TL刺激反应的一个重要决定因素，并探讨了这种解释如何能纳入单词识别的双通路级联（DRC）模型。
