Dynamics of Parasympathetic Activity in Violent Incarcerated Offenders Before, During, and in Recovery From An Emotional Inhibition Task

Dynamics of the autonomic nervous system (ANS) are hypothesized to play a role in the emergence of interpersonal violence. In the present study, we examined continuous activities of the inhibitory parasympathetic pathway of the ANS through the root mean square of successive differences between normal heartbeats (RMSSD) in 22 male offenders who committed interpersonal violence and 24 matched controls from the general population across three successive phases: resting baseline, while performing an emotional Go/No-Go task, and post-task recovery. Results showed that across the three phases, the offender group presented lower RMSSD at baseline (pFDR = .003; Cohen’s d = -1.11), but similar levels during the task, attributed to a significant increase in their RMSSD level (pFDR = .027, Cohen’s d = -1.26). During recovery, no distinction between the two groups was found, but although both groups showed signs of recovering toward baseline values. These findings suggest that violent incarcerated offenders can flexibly engage parasympathetic resources to meet environmental challenges. This underscores the necessity of considering parasympathetic dynamics and its respective mobilization/flexibility to better understand ANS profiles underlying interpersonal violence and designed more tailored intervention.

Cross-Cultural Adaptation and Validation of the Emotional Inhibition Scale in a Chinese Cancer Sample

The Emotional Inhibition Scale (EIS) is a brief measure based on a four-factor model with documented validity in a mood disorder sample that may be useful for assessing emotional inhibition in patient populations, such as individuals with cancer. The present study adapted the EIS to Chinese conditions and examined the psychometric characteristics of the EIS in patients with cancer. The recruited participants comprised a sample of 100 patients (sample 1) and a sample of 202 patients (sample 2) with cancer. The two samples (sample 1 and sample 2) with cancer completed surveys including the EIS. The Toronto Alexithymia Scale-20 was completed by the two sample groups to assess criterion validity. Statistical analyses included internal consistency (sample 1), exploratory factor analyses (EFAs; sample 1), and confirmatory factor analyses (CFAs; sample 2). The results showed that EFA and CFA confirmed the four-factor solution proposed by the original authors (verbal inhibition, self-control, disguise of feelings, and timidity). The internal consistency and test-retest reliability of the EIS were satisfactory. In conclusion, the EIS demonstrated acceptable reliability and validity for assessing emotional inhibition in Chinese-speaking patients with cancer and may be a useful measure for assessing the level of emotional inhibition and the effect of emotional disclosure interventions.

Can We “Brain-Train” Emotional Intelligence? A Narrative Review on the Features and Approaches Used in Ability EI Training Studies

Recent studies had demonstrated that specific emotional intelligence (EI) abilities (as measured using the MSCEIT) were related to better performance on cognitive tasks that involved emotional information but not on their non-emotional counterparts. These findings suggest that cognitive control and other executive functioning processes (e.g., working memory) contribute to EI abilities. A well-functioning EI ability is crucial for a number of everyday activities and life outcomes. However, the evidence for training ability EI remains vague as to how these improvements occur. The purpose of this narrative review was to synthesize findings from past EI training research, specifically focusing on their methodology. This was to identify key aspects of the interventions used, to determine the prototypical features between them, as well as to propose a compelling research agenda for future EI training studies. Based on the features found in these studies, we identified two possible approaches in which EI improvements occurred. The first approach was through increasing emotional knowledge and related competencies through teaching and practice. These features were found in the majority of training interventions using a workshop-style training format, reflections, role-plays, and practice with other participants. The second approach used brain-training principles to improve basic cognitive processes, such as executive control or emotional inhibition. Using a cognitive training approach to EI training can provide several advantages, such as allowing researchers to examine EI improvements using the theories of (1) transfer; (2) plasticity; and (3) process-specific changes.

How Power Affects Emotional Communication During Relationship Conflicts: The Role of Perceived Partner Responsiveness

Prior research indicated that lack of power leads to emotional suppression and low emotional expression during conflicts among strangers. However, little is known about how power affects emotional inhibition in close relationships, where partners are highly interdependent, and achieving one’s goals greatly depends on their partner’s cooperation. In three studies among romantic couples (total N = 994), we examined whether (a) power is related to emotional inhibition during conflicts, (b) perceived partner responsiveness moderates this effect and, (c) which conflict-resolution responses are subsequently enacted. Findings consistently showed that powerless individuals were more likely to inhibit their emotions and consequently to use passive responses during conflicts. However, this only occurred when they perceived lack of responsiveness from their partner. If the partner was perceived as responsive (i.e., showed care, validation, and understanding), power was not related to emotional inhibition and passive resolutions. The importance of partner’s responses in relation to power asymmetry is discussed.

From blocked flows to suppressed emotions: the life of a trope

Internal blockages and build-ups cause disease: traditionally, this principle seemed intuitive both to professionals and the laity, explained conditions as diverse as melancholy and scurvy (among many others), and justified the use of evacuative treatments to get rid of noxious matter. With the collapse of humoral medicine and the establishment of the concept of specific causation, one might have expected time-honoured tropes of obstruction to die off. They did not die off, but moved with the times and adapted to new conditions. Emphasis swung from the noxious character of retained substances to the harms of suppressed urges and emotions—harms including disabling maladjustments as a result of sexual inhibition, and cancer as a result of emotional inhibition. In both cases the causal mechanisms resemble traditional blockages. Theories of noxious inhibitions or psychological blocks, which have a familiar and perhaps even intuitive sound because they have so much history behind them, can easily lead patients into fanciful methods of prevention and treatment.

Where is an emotion? Using targeted visceroception as a method of improving emotion regulation in healthy participants to inform suicide prevention initiatives: a randomised controlled trial

Background William James’ 1884 paper “What is an emotion?” has generated much recent interest in affective science regarding somatic contributions to emotion. Studies of interoception (“sensing the physiological condition of the body”) suggest that sensing specific parts of the body contribute to the production of emotion, namely when sensing the viscera (i.e. ‘visceroception’ of the heart, gut or lungs). Improved visceroception has, for instance, been linked to increased emotional intensity, suggesting a role for interoception in emotion regulation that may pertain specifically to visceral bodily locations. Thus, in addition to asking James’ question, “What is an emotion?”, we ask, “Where is an emotion?”. Further, there is an evidence base pointing to the connections between emotion regulation and suicide, and between interoception and suicide. This is a preliminary trial investigating whether targeted interoception/visceroception improves emotion regulation. Ultimately, the overall project aims to inform suicide prevention efforts. Methods The trial utilises a pre-test/post-test control group design, with two experimental groups undergoing visceroceptive interventions (gut or heart focus) and a control group. The interventions will run for 8 weeks. A spatial cueing task will measure reaction times to bodily changes pertaining to gut or heart focus. A stop/signal task will measure emotional inhibition, which is hypothesised to obscure awareness of active bodily locations. Visceroceptive ability will be tracked using a heartbeat estimation task, a water load test, and by self-report questionnaire. The sample will consist of healthcare professionals and healthcare students. Despite these being groups that represent a relatively high suicide risk among professional and student groups, all participants will be healthy, given the preliminary nature of this trial. Discussion To our knowledge, this will be the first project to address whether emotional feeling presents as a localised bodily phenomenon and whether trained awareness of emotional localisation can improve emotion regulation. It will also be the first to investigate relationships between interoception and emotional inhibition (i.e. whether a sustained interoceptive practice leads to the disinhibition of bodily emotional sensations, which can positively contribute to emotion regulation). These empirical findings on emotion regulation from a healthy sample will be used to inform a desk-based enquiry into the role of embodied emotion in suicide prevention, which may make a significant contribution to a growing evidence base on interoception and suicide.

Neuroimaging Correlates of Emotional Response-Inhibition Discriminate Between Young Depressed Adults With and Without Sub-threshold Bipolar Symptoms

ABSTRACTBackgroundA significant number of subjects with major depression (MDD) exhibit subthreshold mania symptoms (MDD+). This study investigated, for the first time, using emotional inhibition tasks, whether the neurobiology of MDD+ subjects is more akin to bipolar disorder depression (BDD) or to MDD subjects without any subthreshold bipolar symptoms (MDD−).MethodThis study included 118 medication-free young adult subjects (16 – 30 yrs.): 20 BDD, 28 MDD+, 41 MDD−, and 29 HC subjects. Participants underwent fMRI during emotional and non-emotional Go/No-go tasks during which they responded for Go stimuli and inhibited response for happy, fear, emotional (happy + fear) and non-emotional (gender) faces No-go stimuli. Linear mixed effects (LME) analysis for group effects and Gaussian Process Classifier (GPC) analyses was conducted.ResultsMDD− group compared to both the BDD and MDD+ groups, exhibited significantly lower activation in parietal, temporal and frontal regions (cluster-wise corrected p <0.05) for emotional inhibition conditions vs. non-emotional condition. No significant differences were found between BDD and MDD+ groups. GPC classification of emotional vs non-emotional response-inhibition activation pattern showed good discrimination between BDD and MDD− subjects (AUC: 0.70; balanced accuracy: 70% (p = 0.006)) as well as MDD+ and MDD− subjects (AUC: 0.72; balanced accuracy: 67% (p = 0.015)) but less efficient discrimination between BDD and MDD+ groups (AUC: 0.68; balanced accuracy: 61% (p = 0.091)). Notably, classification of the MDD− group was weighted for left amygdala activation pattern.ConclusionUsing an fMRI emotional Go-Nogo task, MDD− subjects can be discriminated from BDD subjects and MDD+.
