在视觉词汇判断中，产生语音效应的词汇音位是什么形式的？作者探索了这样一种假设，即除了语音对比之外，单词的物理语音细节也包括在内。使用词汇判断和使用命名的三个实验比较了印刷单词(例如，plead和pleat)的加工时间，这些单词在说出时在元音长度和总时长方面存在差异。在词汇判断上，长元音词的潜伏期比短元音词长，但在命名上不同。此外，长元音单词的词汇决定比短元音单词的词汇决定更有利于同一性启动，这表明长元音单词的表征达到激活阈值的速度较慢。讨论的重点是语音信息音系学，特别是手势音系学及其对理解阅读习得和表现的潜力。
What form is the lexical phonology that gives rise to phonological effects in visual lexical decision? The authors explored the hypothesis that beyond phonological contrasts the physical phonetic details of words are included. Three experiments using lexical decision and I using naming compared processing times for printed words (e.g., plead and pleat) that differ, when spoken, in vowel length and overall duration. Latencies were longer for long-vowel words than for short-vowel words in lexical decision but not in naming. Further, lexical decision on long-vowel words benefited more from identity priming than lexical decision on short-vowel words, suggesting that representations of long-vowel words achieve activation thresholds more slowly. The discussion focused on phonetically informed phonologies, particularly gestural phonology and its potential for understanding reading acquisition and performance.
