对相邻字母换位（TL 字谜）产生的非单词的误解表明单词识别基于拼写匹配过程，该过程可以容忍字母序列中的微小位置错误。我们报告了五项实验，研究了字母串的拼写和音系特性对 TL 字谜词的误解的影响程度。前两个实验表明，在具有屏蔽目标显示的词汇决策任务中，对于不可发音的 TL 项目，误报的可能性比对可发音的 TL 项目的可能性更大。在实验 3 中，这种效应是在识别任务中观察到的，这是词汇反应和正确识别之间的权衡。第四个实验提供了额外的证据，证明这些效应是通过语音处理而不是拼写处理来介导的。最终的实验表明，诵读困难的参与者在词汇决策中没有表现出可发音效果，这一解释得到了加强。这些结果可以通过字母串的不兼容的语音表示来抑制对 TL 字谜的词汇反应来解释。 (C) 2006 Elsevier Inc. 保留所有权利。
Misperception of nonwords created by adjacent letter transpositions (TL anagrams) indicates that word recognition is based on an orthographic matching process that is tolerant of minor positional errors in the letter sequence. We report five experiments that investigate the extent to which the misperception of TL anagrams is influenced by orthographic and phonological properties of the letter string. The first two experiments demonstrate that in a lexical decision task with masked target displays, false positive responses are more likely for unpronounceable than for pronounceable TL items. In Experiment 3 this effect was observed in an identification task as a trade-off between lexical responses and correct identification. A fourth experiment provided additional evidence that these effects are mediated by phonological rather than orthographic processing. This interpretation was strengthened by a final experiment showing that dyslexic participants did not show the pronounceability effect in lexical decision. These results are interpreted in terms of inhibition of lexical responses to TL anagrams by incompatible phonological representations of the letter string. (C) 2006 Elsevier Inc. All rights reserved.
