职业倦怠是长期工作压力的一种病理后果，在工业化国家的发病率越来越高。先前的研究结果表明，倦怠可能与主观评价的任务需求和认知表现之间的负相关的分离有关，这通常见于健康个体。本研究试图证实这种关系，并调查这种解离是否反映在自我调节的生物标志物中，即，静息迷走神经介导的心率变异性（HRV）。一个异质性样本（N = 65）的工作成年人（M年龄= 43.3，SD = 10; 23.1%男性）与不同程度的倦怠完成三个认知任务（2回，数字-字母，和去/不去），以评估不同领域的执行功能（更新，设置转移，抑制），和各自的需求评级。此外，记录静息时迷走神经介导的HRV，可操作为连续R-R间期的均方根差（RMSSD）。倦怠心理学调节主观任务难度和性能参数的去/不去任务之间的关联，这样，较高的倦怠分数与减少自然发生的自评任务需求和反应抑制之间的负相关。有趣的是，当用HRV代替倦怠时，这种模式也得到了反映。这些研究结果表明，倦怠心理学，自我调节能力的个体差异（指数静息心率变异性），可能会改变一个人的能力，准确的任务评估，一种机制，这可能是潜在的自我评价的认知功能和实际表现之间的分离经历倦怠的个人。
Burnout, a pathological consequence of chronic work stress, shows an increasing incidence rate in industrialized countries. Previous findings indicate that burnout may be linked to a detachment of the negative association between subjectively appraised task demand and cognitive performance, which is typically seen in healthy individuals. The present study sought to confirm this relationship and to investigate whether this dissociation is mirrored in a biological marker of self-regulation, i.e., resting vagally mediated heart rate variability (HRV). A heterogeneous sample (N = 65) of working adults (M age = 43.3, SD = 10; 23.1 % male) with varying degrees of burnout symptomatology completed three cognitive tasks (2-back, number-letter, and go/nogo) to assess different domains of executive functioning (updating, set-shifting, and inhibition), and respective demand ratings. Additionally, vagally mediated HRV at rest, operationalized as the root-mean square differences of successive R-R intervals (RMSSD), was recorded. Burnout symptomatology moderated the association between subjective task difficulty and performance parameters of the go/nogo task, such that higher burnout scores were associated with reductions in the naturally occurring negative association between self-rated task demand and response inhibition. Intriguingly, this pattern was mirrored when replacing burnout with HRV. These findings suggest that burnout symptomatology, and individual differences in self-regulatory capacities (indexed by resting HRV), may alter one’s capacity for accurate task evaluation, a mechanism which could potentially underlie the dissociation between self-rated cognitive function and actual performance among individuals experiencing burnout.
