The early work of Charles W. Eriksen and colleagues provided us with both the flanker task and the concepts of response competition and continuous flow. The model of the flanker task that Eriksen and colleagues developed also includes the idea that processing occurs in two phases and the specific claim that pro-active response inhibition is employed to prevent errors under certain conditions. We first replicated and extended the behavioral evidence that motivated this specific claim and then tested it using a variety of physiological measures. We verified the prediction of Eriksen’s Two-Phase Model of Spatial Selective Attention using the lateralized readiness potential and contingent negative variation. We also clarified a detail of the model using electromyographic activity and response force. We note that this contribution of Charles W. Eriksen has not received the attention that it deserves and that several recent models might need to be revised in light of Eriksen’s work.

Charles W. Eriksen及其同事的早期工作为我们提供了侧翼任务以及响应竞争和持续流动的概念。Eriksen及其同事开发的侧翼任务模型还包括处理过程分为两个阶段的想法，以及明确主张采用主动响应抑制来防止在某些情况下出错的想法。我们首先复制并扩展了激发该特定要求的行为证据，然后使用各种生理措施对其进行了测试。我们使用横向准备就绪潜力和或有的负变化验证了埃里克森的空间选择性注意两阶段模型的预测。我们还使用肌电活动和响应力阐明了该模型的细节。我们注意到Charles W.
