心理科学的一个基本问题涉及人们在多大程度上可以同时执行两项感知运动任务。一些理论家假设，在适应性执行控制下，熟练的程序决策和两个或多个任务的反应选择可以同时进行。这里报告的三个实验支持后一种假设。他们的研究结果表明，经过相对适量的练习，至少有一些参与者在基本选择反应任务的双重任务表现中实现了完美的时间分配。研究结果还表明，观察到的任务之间的干扰可以调制的指示不同的任务优先级和人员的偏好，飞镖（并发）或谨慎（连续）调度任务。鉴于这一结果，未来的研究应该调查究竟何时以及如何获得这种复杂的技能，在双重任务的表现。
A fundamental issue foe psychological science concerns the extent to which people can simultaneously perform two perceptual-motor tasks. Some theorists have hypothesized that skilled procedural decision making and response selection for two or more tasks can proceed at the same time under adaptive executive control. The three experiments reported here support this latter hypothesis. Their results show that after relatively modest amounts of practice, at least some participants achieve perfect time sharing in the dual-task performance of basic choice reaction tasks. The results also show that observed interference between tasks can be modulated by instructions about differential task priorities and personnel preferences for darting (concurrent) or cautious (successive) scheduling tasks. Given this outcome, future research should investigate exactly when and how such sophisticated skills in dual-task performance are acquired.
