什么时候换？了解绩效权衡如何形成双任务策略伦敦大学学院邓肯·布鲁姆比伦敦大学学院尼娜·德尔罗萨里奥大学学院伦敦基督教詹森大学学院伦敦摘要：我们使用一个新颖的双任务范式来调查人们如何调整他们的策略，使他们的注意力在任务之间交叉，以满足不同的绩效目标。这项研究要求参与者在驾驶模拟车辆时，从辅助显示器上编码并输入一系列路线指令。给出了实验说明，鼓励参与者优先考虑安全驾驶或第二导航任务。结果表明，参与者通过改变他们交错任务的频率和通过改变他们在两次访问第二显示器之间花费的时间量来达到所需的任务目标。我们使用一个用于模拟驾驶员分心效应的框架来解释这些数据。该模型解释了观察到的两个优先条件之间的绩效衡量变化，以及观察到的战略变化。综上所述，这些结果支持这样一种观点，即人们可以在多任务环境中策略性地分配注意力，以满足特定的表现标准。
When to Switch? Understanding How Performance Tradeoffs Shape Dual-Task Strategy Duncan Brumby University College London Nina del Rosario University College London Christian Janssen University College London Abstract: We use a novel dual-task paradigm to investigate how people adapt their strategy for interleaving attention between tasks to meet varying performance objectives. The study required participants to encode and enter a series of route instructions from a secondary display while driving a simulated vehicle. Experimental instructions were given to encourage participants to either prioritize safe driving or the secondary navigation task. Results show that participants met the required task objective by varying the frequency that they interleaved tasks and by varying the amount of time they spent in between visits to the secondary display. We explain these data using a framework for modeling driver distraction effects. The model explained the observed change in performance measures between the two priority conditions and also the observed change in strategy. Taken together these results support the idea that people can strategically allocate attention in multitask settings to meet specific performance criteria.
