In this article, we explore the transposed-letter priming effect (e.g., jugde-JUDGE vs. jupte-JUDGE), a phenomenon that taps into some key issues on how the brain encodes letter positions and has favoured the creation of new input coding schemes. However, almost all the empirical evidence from transposed-letter priming experiments comes from nonword primes (e.g., jugde-JUDGE). Indeed, previous evidence when using word-word pairs (e.g., causal-CASUAL) is not conclusive. Here, we conducted five masked priming lexical decision experiments that examined the relationship between pairs of real words that differed only in the transposition of two of their letters (e.g., CASUAL vs. CAUSAL). Results showed that, unlike transposed-letter nonwords, transposed-letter words do not seem to affect the identification time of their transposed-letter mates. Thus, prime lexicality is a key factor that modulates the magnitude of transposed-letter priming effects. These results are interpreted under the assumption of the existence of lateral inhibition processes occurring within the lexical level-which cancels out any orthographic facilitation due to the overlapping letters. We examine the implications of these findings for models of visual-word recognition.
在本文中，我们探讨了字母换位启动效应（例如，jugde-JUDGE与jupte-JUDGE），这一现象涉及大脑如何编码字母位置的一些关键问题，并推动了新输入编码方案的创建。然而，几乎所有来自字母换位启动实验的实证证据都来自非词启动（例如，jugde-JUDGE）。事实上，之前使用词-词对（例如，causal-CASUAL）的证据并不确凿。在此，我们进行了五项掩蔽启动词汇判断实验，研究仅在两个字母换位上存在差异的真实词对（例如，CASUAL与CAUSAL）之间的关系。结果表明，与字母换位非词不同，字母换位词似乎不会影响其字母换位配对词的识别时间。因此，启动词的词汇性是调节字母换位启动效应大小的关键因素。这些结果是在词汇层面存在侧向抑制过程的假设下进行解释的，该过程会抵消由于字母重叠而产生的任何正字法促进作用。我们研究了这些发现对视觉词识别模型的影响。
