作者探讨了外显清晰度与言语产生中枢过程之间的在线关系。在两个实验中，操纵Stroop干扰的时间在颜色命名，作者发现命名行为可以转移之间表现出一个阶段或级联模式的处理，这取决于任务的要求：Stroop干扰对命名持续时间的影响，只有当有增加的压力，以加快反应。在一个应用于颜色命名的简单连接主义信息处理模型中，作者通过操纵一个被称为“增益”的参数来解释当前的结果，调节网络内的信息积累速率。结果进行了讨论的战略控制机制和认知与行动之间的联系。
The authors investigated the on-line relationship between overt articulation and the central processes of speech production. In 2 experiments manipulating the timing of Stroop interference in color naming, the authors found that naming behavior can shift between exhibiting a staged or cascaded mode of processing, depending on task demands: An effect of Stroop interference on naming durations arose only when there was increased pressure for speeded responding. In a simple connectionist model of information processing applied to color naming, the authors accounted for the current results by manipulating a single parameter, termed "gain," modulating the rate of information accrual within the network. Results are discussed in relation to mechanisms of strategic control and the link between cognition and action.
