The goal of the current study was to measure the processing demands on the stages of information processing with internal and external foci of attention. Participants completed simple and two-choice reaction time tasks with internal and external foci of attention. Donders' subtraction method was used to isolate the cumulative duration of stages unique to simple and choice reaction time tasks. Mean reaction time was comparable with internal and external foci of attention in simple and two-choice reaction time tasks. These results suggest that processing demands were comparable with internal and external foci of attention. We hypothesize that there was not a processing advantage for an external focus in simple reaction time because the required movements had low movement complexity.
本研究的目的是测量在内部和外部注意焦点的信息加工阶段的加工需求。参与者完成了内部和外部注意焦点的简单和二择一反应时任务。达登斯减法法被用来分离简单和选择反应时任务特有的阶段的累积持续时间。简单和二择一反应时任务中，内部和外部注意焦点的平均反应时相当。这些结果表明，加工需求与内部和外部注意焦点相当。我们假设，在简单反应时，外部焦点没有加工优势，因为所需的运动具有较低的运动复杂性。
