An emotional processing writing intervention and heart rate variability: the role of emotional approach

Emotion contagion and physiological synchrony: The more intimate relationships, the more contagion of positive emotions

The study aimed to explore how interpersonal closeness (friends vs. strangers) and emotion type (positive vs. negative) influenced emotion contagion and physiological synchrony between interacting partners. Twenty-eight friend dyads (n = 56) and 29 stranger dyads (n = 58) participated in an emotion contagion laboratory task. In each dyad, one participant, the 'sender', was randomly asked to watch a film clip (neutral, positive, or negative), while their partner, the 'observer' passively observed the sender's facial expressions. Participants' electrocardiograms (ECG) and facial electromyography (EMG) signals were recorded using the BIOPAC system. Results revealed that observing the sender's facial expressions led to the observer's spontaneous mimicry and emotional contagion, accompanied by enhanced physiological synchrony between interacting partners. In the positive emotion condition, the observers reported more positive emotions and displayed stronger zygomaticus major activity in friend dyads than in stranger dyads. Greater physiological synchrony (heart rate and heart rate variability) between interacting partners was also observed in friend dyads than in stranger dyads in the positive emotion condition. These results indicate that positive emotion contagion is more likely to occur between close partners than negative emotion contagion.

Emotional processing writing and physiological stress responses: understanding constructive and unconstructive processes

Writing about emotions related to a life stressor is thought to promote coping via emotional processing. However, all styles of emotional processing may not be beneficial to managing stress. Such styles can include constructive (planning/problem-solving, meaning-making) and unconstructive (rumination, worry) forms. This study utilised a randomised experimental design to examine the physiological impact (as indexed by heart rate variability, salivary cortisol reactivity and recovery) of expressive writing with guidance to promote constructive and discourage unconstructive styles (EP+) versus expressive writing with no guidance (EP). Participants (N = 151) engaged in three sessions of expressive writing anchored to a self-nominated stressor over three days. Stress reactivity was measured two weeks later in response to a stress recall task. There was no effect of group on cortisol reactivity, cortisol recovery, or HRV reactivity. However, there was a significant interaction of group and subjective stressfulness of the nominated stressor was observed, such that EP+ was associated with greater cortisol recovery. Those with more taxing stressors may be better equipped to process emotions with guidance on emotional processing styles.

Real-Time Psychophysiological and Writing Correlates of Expressive Writing

Concealing memories and emotions associated with a traumatic event seems to have negative effects on health. Re-enacting those events through writing is an opportunity to disclose such memories and emotions, and especially for emotion regulation. To study this, 57 university students were randomly assigned to one of two groups. They either completed an expressive writing or a neutral writing task. Real-time writing and psychophysiological data were recorded throughout the experiment to examine writing dynamics associated with emotion regulation and its psychophysiological correlates (electrodermal activity and electrocardiography measures). The results showed that the expressive group (EG) paused for longer than the control group (CG) denoting a positive and medium effect size ( η p 2 = .10 ) . Furthermore, during and after writing, the EG showed a higher low frequency/high frequency ratio than the CG, evidencing a positive and large effect size ( η p 2 = .22 ) . These real-time findings are interpreted as signs of emotion regulation happening during writing.

State and Trait Rumination Effects on Overt Attention to Reminders of Errors in a Challenging General Knowledge Retrieval Task

Rumination is a recurrent and repetitive manner of thinking that can be triggered by blockage of personally relevant goals, creating a temporary state of abstract and evaluative self-focus. Particularly when focused on passive “brooding” over one’s problems and feelings, however, rumination can increase negative affect, interfere with problem-solving, and, through a negative feedback cycle, become a chronic trait-like style of responding to personal challenges, particularly in women. Given the pervasiveness of rumination and its potential impact on cognitive processes and emotional states, the present study asks how it impacts attention to feedback that either reminds individuals of goal-state discrepancies (reminders of errors) or could help to remediate them (corrective information). Using eye-tracking, we examined both state and trait rumination effects on overt measures of attention [first fixation duration (FFD) and total fixation duration (TFD)] during simultaneous presentation of these two types of feedback following failed attempts to answer challenging verbal general knowledge questions (average accuracy ∼30%). After a pre-induction baseline, we induced either a state of rumination using a series of writing exercises centered on the description of an unresolved academic concern or a state of distraction by centering writing on the description of a neutral school day. Within our women-only sample, the Rumination condition, which writing analysis showed was dominated by moody brooding, resulted in some evidence for increased initial dwell time (FFD) on reminders of incorrect answers, while the Distraction condition, which did not elicit any rumination during writing, resulted in increased FFD on the correct answer. Trait brooding augmented the expression of the more negative, moody brooding content in the writing samples of both Induction conditions, but only influenced TFD measures of gaze duration and only during the pre-induction baseline, suggesting that once the inductions activated rumination or distraction states, these suppressed the trait effects in this sample. These results provide some support for attentional-bias models of rumination (attentional scope model, impaired disengagement hypothesis) and have implications for how even temporary states of rumination or distraction might impact processing of academic feedback under conditions of challenge and failure.

Emotional approach coping in older adults as predictor of physical and mental health

Emotional approach coping involves active attempts at emotional expression and processing in response to stressful circumstances. This study tested whether dispositional emotional approach coping processes predict changes in physical and mental health in community-dwelling older adults, particularly within the context of higher perceived stress. To test this, older adults (N = 150) completed assessments of emotional expression and emotional processing at study entry. They also completed measures of perceived stress, depressive symptoms, and ill-health (a composite of subjective and objective physical health indicators, which included blood draw for collection of biomarkers), every 6 months over 4.5 years. Emotional processing and emotional expression were not related significantly to ill-health at study entry. However, emotional processing (but not emotional expression) significantly predicted changes in ill-health. At higher levels of emotional processing, ill-health remained low and stable; at lower levels of emotional processing, ill-health increased over time. However, when perceived stress was high, higher emotional processing and emotional expression were related to lower depressive symptoms at study entry, but higher emotional processing was associated with increasing depressive symptoms over time. Emotional approach coping processes evidence prospective relations with health outcomes, which are partially conditioned by stress perceptions. Emotional processing appears to have a protective impact against declining physical health. Predictive relationships for depressive symptoms are more complex. Older adults with chronically high perceived stress might benefit from interventions that target emotion-regulating coping processes. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

The effects of interpersonal emotional expression, partner responsiveness, and emotional approach coping on stress responses

[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.
