Individuals with job burnout symptoms often report having cognitive difficulties, but related electrophysiological studies are scarce. We assessed the impact of burnout on performing a visual task with varying memory loads, and on involuntary attention switch to distractor sounds using scalp recordings of event-related potentials (ERPs). Task performance was comparable between burnout and control groups. The distractor sounds elicited a P3a response, which was reduced in the burnout group. This suggests burnout-related deficits in processing novel and potentially important events during task performance. In the burnout group, we also observed a decrease in working-memory related P3b responses over posterior scalp and increase over frontal areas. These results suggest that burnout is associated with deficits in cognitive control needed to monitor and update information in working memory. Successful task performance in burnout might require additional recruitment of anterior regions to compensate the decrement in posterior activity.

Introduction: This study aims to evaluate the effects of live music therapy on heart rate variability (HRV) and self-reported stress and anxiety among hospitalized women with high-risk pregnancies. A total of 102 women at an antenatal ward due to pregnancyrelated complications participated in a randomized controlled trial. Methods: The participants were randomly assigned to a music therapy group (N = 52) or control group (N = 50). The women in the music therapy group received live music therapy on three consecutive days, for half an hour at a time. The participants belonging to the control group were instructed to rest for equally long time periods. The physiologic stress of the participants was assessed using HRV measures. The participants also rated their perceived stress and anxiety. The physiologic stress of the participants was assessed using 12 HRV measures. Results: The SD2 measure of HRV increased significantly more in the music therapy group than in the control group during the therapy sessions. Moreover, the low frequency (LF) HRV measure decreased during the three-day therapy period. The self-reported stress was not significantly altered after the intervention. For women with high initial self-reported anxiety in both groups, their anxiety was significantly reduced during the three-day period.

Individuals with prolonged occupational stress often report difficulties in concentration. Work tasks often require the ability to switch back and forth between different contexts. Here, we studied the association between job burnout and task switching by recording event-related potentials (ERPs) time-locked to stimulus onset during a task with simultaneous cue-target presentation and unpredictable switches in the task. Participants were currently working people with severe, mild, or no burnout symptoms. In all groups, task performance was substantially slower immediately after task switch than during task repetition. However, the error rates were higher in the severe burnout group than in the mild burnout and control groups. Electrophysiological data revealed an increased parietal P3 response for the switch trials relative to repetition trials. Notably, the response was smaller in amplitude in the severe burnout group than in the other groups. The results suggest that severe burnout is associated with inadequate processing when rapid shifting of attention between tasks is required resulting in less accurate performance.
