摘要本研究旨在探讨警告和未警告的警觉性需求转换对绩效和自我报告压力的影响。20名观察员（10名女性和10名男性）被随机分配到由信号显著性（高和低显著性信号）和切换（无切换，切换警告，切换无警告）的因子组合产生的六种条件中的每一种。收集了绩效指标和自我报告的压力状态（任务参与，苦恼和担忧）。虽然需求转变确实会破坏后续性能，增加个体内的变异性，但整体性能效率不受切换或警告的影响。需求转变，无论是否得到警告，都会增加自我报告的痛苦。一个动态模型的性能压力可能是必要的，研究采用警惕任务，在未来可能是有用的，发展这种性能压力模型。
Abstract The present study was designed to explore the effects of warned and unwarned demand transitions in vigilance on performance and self-reported stress. Twenty observers (10 women and 10 men) were assigned at random to each of six conditions resulting from the factorial combination of signal salience (high and low salience signals) and switching (no switch, switch with warning, and switch without warning). Performance metrics and self-reported stress state (Task Engagement, Distress, and Worry) were collected. While demand transitions did destabilize subsequent performance, increasing intra-individual variability, overall performance efficiency was uninfluenced by either switching or warning. Demand transitions, whether warned or not, increased self-reported distress. A dynamic model of performance stress may be necessary and research employing vigilance tasks in the future may be useful for developing this performance-stress model.
