Attention to Emotional Information Is Associated With Cytokine Responses to Psychological Stress.

ABSTRACT: This study aimed to investigate the impact of mental stress on salivary cytokines and attention to emotional stimuli, as well as associations between stress-induced changes of immune and cognitive parameters. In a randomized order a total of 60 young adults were assigned to one of two stress conditions with varying stress intensity. High stress was induced by a socially evaluated Paced Auditory Serial Addition Test (PASAT). As a low stress task a paper-and-pencil version of PASAT was administered. Salivary cytokines were measured before, 5 min after, and 45 min after completion of the stress task, and were assayed for pro- and anti-inflammatory cytokines. Three distinct types of attention - alerting, orienting, and executive control - were measured by the modified Emotional Attention Network Test Integration (E-ANTI). IL-1β and IL-6 increased only in the high-stress group. Significant increases in IFN-α, IFN-γ, TNF-α, and IL-10 at 45 min after stress induction (all p's < 0.05) were observed in both the high-stress and the low-stress group. Alerting attention was positively related to more pronounced increases in IFN-α and TNF-α in both groups. Further, better orienting attention after presentation of negative cues was associated with higher increases in IFN-α, TNF-α, IL-2, IL-5, and IL-10 in both groups, and higher overall levels of IFN-α, IFN-γ, and IL-12p70 in the high-stress group. There were no systematic gender differences in cytokine responses. We conclude that attention processes modulate the increases of salivary cytokines after stress exposure, and that these effects depend on stress level, particular attention network, and stimulus valence.

Project description:[Correction Notice: An Erratum for this article was reported online in Emotion on Sep 5 2019 (see record 2019-52812-001). In the article, two text call outs for figures are incorrect. At the end of the "Negative emotional responses" section under the "Psychological Stress Responses" heading, "(see Figure 7)" should have been deleted. Under the "Negative task-related ruminative thoughts" heading in that same section, "(see Figure 5)" in the first paragraph should be "(see Figure 7)."] Expressing emotions is a common strategy for coping with stress. Yet, little is known about the effects of using this strategy in close relationships, or when and for whom emotional expression is effective. This study examined romantic partner responsiveness and the dispositional tendency to use emotional approach coping (EAC; the processing and expression of emotions) as moderators of the effects of experimentally manipulated emotional expression on stress responses to a laboratory stressor. We brought couples (N = 145) to the lab and randomly assigned 1 partner (the participant) to perform a stressful task. We manipulated whether participants expressed their feelings about the task to their partner (expression vs. no-expression), and whether participants received supportive messages from their partners (as an indicator of partner responsiveness; support vs. no-support). We examined physiological stress responses (cortisol and salivary alpha-amylase [sAA]), negative emotional stress responses (anxiety and self-conscious emotions), and post-task ruminative thoughts. Participants high in EAC showed larger sAA and cortisol responses and reported more negative post-task ruminative thoughts after emotionally expressing to their partners, but partner support mitigated the effect on cortisol. Participants low in EAC showed smaller cortisol responses and reported less negative emotional responses and fewer negative post-task ruminative thoughts after emotionally expressing to their partners. Receiving partner support reduced negative emotional responses for people high in EAC, but increased negative emotional responses for those low in EAC. These results may help explain when and for whom emotional expression is an effective means of coping in the immediate context of a stressor.
