In an attempt to integrate theorizing on action shielding with affective influences on effort-related cardiovascular response, an experiment with N = 115 university students (90% women) tested whether working on a task by personal choice versus external assignment moderates the effect of happy versus sad background music on effort-related cardiovascular response during task performance. We predicted strong action shielding and low receptivity for incidental affective influences when participants could ostensibly choose the task to be performed. Given the difficult nature of the task, we thus expected strong effort-related cardiovascular responses due to high commitment when the task was chosen. By contrast, for assigned-task participants, we expected high receptivity for incidental affective influences and thus predicted strong cardiovascular reactivity when they were exposed to happy music but low responses due to disengagement when they were exposed to sad music. Effects on responses of cardiac pre-ejection period, systolic blood pressure, and heart rate confirmed our effort-related predictions. Apparently, personal choice of a task can immunize individuals against incidental affective influences on resource mobilization.
为了将行动屏蔽的理论与努力相关的心血管反应的情感影响结合起来，一项有 115 名大学生（90%为女性）参与的实验测试了个人选择任务与外部任务分配是否会影响在执行任务期间，快乐与悲伤的背景音乐对努力相关的心血管反应的影响。我们预测，当参与者可以表面上选择要执行的任务时，会有强烈的行动屏蔽和对偶然情感影响的低接受度。考虑到任务的难度，我们预计当任务被选择时，由于高承诺，会有强烈的与努力相关的心血管反应。相比之下，对于分配任务的参与者，我们预计他们会对偶然的情感影响有很高的接受度，因此当他们接触到快乐音乐时，我们预测会有强烈的心血管反应，但当他们接触到悲伤音乐时，由于脱离接触，反应会很低。心脏射血前期、收缩压和心率的反应证实了我们与努力相关的预测。显然，个人选择任务可以使个体免受资源动员的偶然情感影响。
