摘要
通过1个预试验和2个正式试验探讨自我损耗程度对状态焦虑影响持续性注意控制的调节作用。预试验检验不同程度自我损耗对自我控制的影响,采用顺序任务范式,通过控制自我损耗任务的持续时间以达到不同程度的自我损耗(高、中、低、无),结果显示,自我损耗任务持续时间越长,在后续自控任务上的表现越差。试验一检验自我损耗程度对状态焦虑影响持续注意认知任务(Visual-CCPT)的调节作用。参与者在完成不同持续时间的自我损耗任务后,在低、高状态焦虑下完成持续注意认知任务,结果显示,状态焦虑对认知任务表现有促进作用,且与低、无自我损耗相比,状态焦虑的促进作用在参与者处于中、高自我损耗程度下更大。试验二检验自我损耗程度对状态焦虑影响持续注意运动任务(投掷飞镖)的调节作用,结果显示,状态焦虑对飞镖任务表现也起到了促进作用,但是自我损耗程度的调节作用消失了,可能原因是,飞镖任务的敏感性不如认知任务。研究结果提示,状态焦虑存在动机作用,处于高程度自我损耗的个体更容易受到动机作用的影响。
The present study consisted of one pilot experiment and two formal experiments to investigate the moderating effect of the degree of ego depletion （high, moderate, low, and none） on the effect of state anxiety on continuous attentional cognitive task and motor task. Pilot experiment examined the effects of the degree of ego depletion on self-control. Sequential-task paradigm was utilized, and the degree of ego depletion was manipulated by the duration of ego de- pletion task. The results showed that longer duration of depletion task led to worse performance of subsequent self-control task in general. Experiment 1 examined the moderating effect of ego depletion on the effect of state anxiety on continuous attentional task （visual-CCPT）. Participants conducted ego depletion task with different duration, respectively. Then they conducted the visual-CCPT task under low and high state anxiety. Results showed that state anxiety fa- vored the performance of visual-CCPT task and there was moderating effect of ego depletion （the benefit of state anxiety was larger in the condition of medium and high ego depletion compared with low and none ego depletion. Experiment 2 examined the moderating effect of ego depletion on the effect of state anxiety on motor task. Results showed that the benefit of state anxiety on performance is significant, which was consistent with Experiment 1. Moreover, there was no moderating effect of ego depletion, which implied that the sensitivity of darting task is lower than cognitive task. These findings indicated that state anxiety induced in lab will favor attentional performance of continuous attentional task or motor task and the benefit of state anxiety on continuous attentional control is larger under medium and high ego depletion compared with low and none ego depletion.
