Printed words that have a transposed-letter (TL) neighbor (e.g., angel has the TL neighbor angle) have been shown to be more difficult to process, in a range of paradigms, than words that do not have a TL neighbor. However, eye movement evidence suggests that this processing difficulty may occur on only a subset of trials. To investigate this issue, here we fit the ex-Gaussian distribution to naming latencies. The presence of a TL neighbor affected the τ parameter of the distribution of latencies, but there was no effect on the μ parameter. Vincentile plots confirmed that only slow responses were affected by the presence of a TL neighbor. These results contrast with the distributional effects of other variables on naming latency and are interpreted as suggesting that the TL effect involves inhibition of an incorrect output rather than broader competition between lexical entries.
已证明，与没有 TL 邻居的单词相比，具有字母换位（TL）邻居（例如，单词 angel 就有 TL 邻居 angle）的印刷单词在各种范例中更难以处理。但是，眼动证据表明，这种处理困难可能仅在一部分试验中发生。为了研究这个问题，我们在这里将 Ex-Gaussian 分布拟合到命名潜伏期。TL 邻居的存在会影响潜伏期分布的 τ 参数，但对 μ 参数没有影响。文森特图证实，只有慢反应受到 TL 邻居存在的影响。这些结果与命名潜伏期的其他变量的分布效应形成对比，可解释为表明 TL 效应涉及对不正确输出的抑制，而不是词汇条目之间的更广泛竞争。
