Three different speech production paradigms assessed C. T. Kello, D. C. Plaut, and B. MacWhinney's (2000) claim that the characteristics of speech production flexibly vary between staged and cascaded modes depending on task demand. All experiments measured response latencies and durations of single words without and with a response deadline. Experiment 1 used a picture-word interference task; Experiment 2 blocked pictures either by semantic category or by word-initial overlap; and Experiment 3 used a Stroop paradigm. In all cases, systematic effects of semantic and form relatedness were obtained on latencies but not on response durations. These results support the assumption that articulation, as assessed by response duration, is never influenced by central cognitive processes once a response has been initiated.
三种不同的言语产生范式评估了C.T.凯洛、D.C.普劳特和B.麦克温尼（2000年）提出的主张，即言语产生的特征会根据任务需求在分阶段模式和级联模式之间灵活变化。所有实验都测量了有无反应期限情况下单个单词的反应潜伏期和持续时间。实验1使用了图片-单词干扰任务；实验2根据语义类别或单词起始重叠对图片进行分组；实验3使用了斯特鲁普范式。在所有情况下，语义和形式相关性对潜伏期有系统性影响，但对反应持续时间没有影响。这些结果支持了这样一种假设，即一旦反应启动，通过反应持续时间评估的发音就不会受到中央认知过程的影响。
