Situation selection for the regulation of emotion responses: Non-meaningful choice options retain partial physiological regulatory impact.

Situation selection consists in choosing an upcoming emotional situation in order to regulate emotions. It was found to be a strategy with powerful effects on emotional negative experience and physiological arousal. Situation selection is supposed to be efficient through the empowering effect of choice itself. In the present study, we wanted to replicate results on Situation selection efficiency and explore its limits by examining the implications of a non-meaningful choice procedure preceding the emotional trigger, expecting that even this non-meaningful choice would be regulatory. Sixty-one participants (40 females, mean age 21.4 years) were presented with emotional pictures, either with no particular instruction (no regulation) or with the task to make a choice between two options. This task was either a classical Situation selection task, with the label corresponding to the image that could be later seen (Word Situation selection), or non-meaningful options (Non-word Situation selection). The effect of Situation selection for negative experience was replicated. Effects on physiological arousal showed reduced heart rate and respiratory rate at the end of the viewing period, particularly for positive viewing. In negative viewing, Non-word Situation selection did not reduce negative experience, but did reinforce the calming effect of Situation selection on heart and respiratory rate. These results confirm Situation selection as a valid emotion regulation strategy, particularly regarding physiological arousal. Significant understanding of the options seems to constitute a strategic part of the regulation on the full spectrum of emotion responses but is not mandatory if only some specific physiological responses are targeted.

Factors associated with repetitive violent behavior of psychiatric inpatients.

A small number of psychiatric inpatients displays a large proportion of Violent Behaviors (VB). These can have a major impact on both victims and patients themselves. This study explored personal, situational and institutional risk factors and their combined effects, which could lead to repetitive VB (three or more assaults). Data from 4518 patients, aged 18 to 65, admitted to an acute psychiatric care facility, were included in the analysis. VB, defined as physical aggressions against another person, were assessed by the Staff Observation Aggression Scale-Revised. 414 VB were reported during the study period, involving 199 patients. 0.75 % of all patients were repetitively violent and committed 43% of all VB. Factors that were linked to repetitive VB were living in sheltered housing before hospitalization, suffering from schizophrenia with substance abuse comorbidity, cumulating hospitalization days and some situational factors, like the fact of being in nursing offices and pharmacies. When all personal, situational and institutional factors were considered together, the combined effects of length of stay and living in sheltered housing increased the risk of repetitive VB. We have identified a small group of vulnerable patients for whom new modalities of inter-institutional networking should be developed to prevent repetitive VB.

Efficiency of Illusory Choice Used as a Variant of Situation Selection for Regulating Emotions: Reduction of Positive Experience But Preservation of Physiological Downregulation.

Situation selection is an emotion regulation strategy consisting in choosing a future emotional situation. Past research showed that Situation selection triggers a decrease in negative experience, exocrine reactions and respiratory activity, while maintaining stable positive experience. In this study, we wanted to replicate these observations and test emotional responses that follow an Illusory choice, i.e., when the chosen situation is not available and replaced by another. Sixty-eight participants watched emotional pictures, either in a condition in which the images were imposed, or in a condition in which they could perform a choice. In these latter trials, participants saw either the chosen option (Situation selection) or the non-selected option (Illusory choice). Continuous recordings of experience and physiological arousal showed that, unlike Situation selection, Illusory choice decreased positive experience but not negative experience. Strikingly, however, we showed that having the choice decreased skin conductance and respiratory arousal, regardless of whether the choice was respected or not. These results have important implications regarding emotion regulation through Situation selection, since having the choice about the upcoming emotional situation, no matter if we really end up in this situation, gives a sense of control that may be sufficient to alleviate physiological responses to stressors.

The simultaneous use of Emotional suppression and Situation selection to regulate emotions incrementally favors physiological responses.

BACKGROUND: Emotion regulation alters the trajectories of emotional responses and, when effective, transforms the emotional responses to help individuals adapt to their environment. Previous research has mainly focused on the efficiency of regulation strategies performed individually at a given time. Yet, in daily life, it is likely that several strategies are often combined. Thus, we question in this study the combinatorial efficiency of two emotion regulation strategies, Situation selection and Emotional suppression. METHODS: In a within-subject design, sixty-five participants were asked to implement either no strategy, Situation selection only, Emotional suppression only, or both strategies together (four conditions) while looking at various emotionally charged images. Experience, expressivity, and physiological arousal were recorded throughout the viewing. Repeated-measures ANOVAs and corrected post-hoc tests were used for analyzing the data. RESULTS: The results of the combined strategies showed that Emotional suppression canceled the beneficial impact of Situation selection on negative experience, while significantly increasing the impact on cardiac activity. The use of both strategies together had a greater effect on respiratory function with an enhanced decrease in respiratory rate and amplitude. CONCLUSIONS: The combinatorial effect of emotion regulation strategies is different according to the emotional response that the individual needs to regulate. The simultaneous use of Situation selection and Emotional suppression could be particularly beneficial to relieve physiological symptoms.

Reasons, Years and Frequency of Yoga Practice: Effect on Emotion Response Reactivity.

Yoga practice, even in the short term, is supposed to enhance wellbeing and counteract psychopathology through modification of emotion reactivity. Yoga teaches that emotional responses may be less pronounced with longer and more frequent practice, and potentially when people perform yoga for mental rather than physical reasons. We tested 36 yoga practitioners of varying experience (between 6 months and 11 years of practice). We assessed participants' self-reported emotional experience and peripheral physiological reactions (heart rate, skin conductance, respiration) when seeing positive and negative pictures. Results were analyzed as a function of the years of, frequency of, and reasons for yoga practice. We found a heart rate increase with the degree participants performed yoga for mental reasons. In addition, years of yoga practice were significantly associated with reduced abdominal respiratory rate when facing negative pictures, speaking in favor of reduced arousal with yoga experience. Finally, regarding frequency of practice, a higher frequency in the last month was linked to less negative and positive experiences as well as a reduced abdominal respiratory amplitude when viewing positive pictures. Altogether, these results demonstrate that intense short-term yoga practice might relate to a (i) decrease in the intensity of self-reported emotional experiences and (ii) deepened respiration. Short-term effects might be shaped by what participants expect as practice benefits. However, several years of practice might be needed to decrease respiratory arousal in the face of negative situations, which likely is a manifestation of an evolution in the emotion regulation process.

The regulatory effect of choice in Situation Selection reduces experiential, exocrine and respiratory arousal for negative emotional stimulations.

Situation selection is a seldom studied emotion regulation strategy that entails choosing an upcoming emotional situation. Two mechanisms may drive its regulatory effect on emotional responses. One relates to the evaluation of the chosen option, people generally selecting the most positive. The other one implies that having the choice regarding the upcoming emotional situation is already regulatory, independently of what we choose. This research aimed at investigating this latter hypothesis. In a within-subject design, we compared emotional responses of 65 participants when they viewed negative and positive images they could select (use of Situation selection) vs. when they were imposed the exact same images (Situation selection not used). Results show that having the choice in negative contexts decreased negative experience, skin conductance, and respiration reactivity, while enhancing expressivity and cardiovascular reactivity. In positive contexts, choosing generally reinforced the image calming effect. Thus, contrary to other strategies that are efficient for negative but usually impair positive reactions (e.g., distraction), Situation selection may be used widely to reduce negative experience, while avoiding depletion of positive responses. This is particularly notable in emotion experience. Remarkably, these effects are not driven by the content of the situations, but by the act of choosing itself.

Relationship Between Emotions, Emotion Regulation, and Well-Being of Professional Caregivers of People With Dementia.

So far, limited research has been carried out to better understand the interplay between the emotions, the use of emotion regulation strategies, and the well-being of professional caregivers of People with Dementia (PwD). This pilot study (N = 43 professional caregivers) aimed to (1) describe the type and frequency of emotions experienced at work; (2) analyze the associations between experienced emotions, emotion regulation strategies, and well-being; and (3) test whether the use of specific emotion regulation strategies moderates the relationship between experienced emotions and emotional exhaustion. In the challenging context of professionally caring for PwD, results suggest that (1) caregivers experience positive emotions more frequently than negative emotions; (2) caregivers using relatively inappropriate regulation strategies are more likely to experience negative emotions, less likely to experience positive emotions, and have poorer physical and mental health; and (3) expressive suppression significantly moderates the relationship between positive experienced emotions and emotional exhaustion.

The temporal dynamics of emotional acceptance: Experience, expression, and physiology.

Emotional acceptance has begun to attract considerable attention from researchers and clinicians alike. It is not yet clear, however, what effects emotional acceptance has on early emotion response dynamics. To address this question, participants (N = 37) were shown emotional pictures and cued either to simply attend to them, or to accept or suppress their emotional responses. Continuous measures of emotion experience, expressive behavior, and autonomic responses were obtained. Results indicated that, compared to no regulation, acceptance led to more positive emotions, transiently enhanced expressivity, and lowered respiratory rate. Compared to suppression, acceptance led to more positive emotions, stronger expressivity, and smaller changes in heart rate, blood pressure, and pulse amplitude, as well as greater oxygenation. Acceptance and suppression thus have opposite effects on emotional response dynamics. Because acceptance enhances positive emotion experience and expression, this strategy may be particularly useful in facilitating social interactions.

Emotion regulation and emotion coherence: evidence for strategy-specific effects.

One of the central tenets of emotion theory is that emotions involve coordinated changes across experiential, behavioral, and physiological response domains. Surprisingly little is known, however, about how the strength of this emotion coherence is altered when people try to regulate their emotions. To address this issue, we recorded experiential, behavioral, and physiological responses while participants watched negative and positive pictures. Cross-correlations were used to quantify emotion coherence. Study 1 tested how two types of suppression (expressive and physiological) influence coherence. Results showed that both strategies decreased the response coherence measured in negative and positive contexts. Study 2 tested how multichannel suppression (simultaneously targeting expressive and physiological responses) and acceptance influence emotion coherence. Results again showed that suppression decreased coherence. By contrast, acceptance was not significantly different from the unregulated condition. These findings help to clarify the nature of emotion response coherence by showing how different forms of emotion regulation may differentially affect it.

Alternatively spliced domains interact to regulate BK potassium channel gating.

Most human genes contain multiple alternative splice sites believed to extend the complexity and diversity of the proteome. However, little is known about how interactions among alternative exons regulate protein function. We used the Caenorhabditis elegans slo-1 large-conductance calcium and voltage-activated potassium (BK) channel gene, which contains three alternative splice sites (A, B, and C) and encodes at least 12 splice variants, to investigate the functional consequences of alternative splicing. These splice sites enable the insertion of exons encoding part of the regulator of K(+) conductance (RCK)1 Ca(2+) coordination domain (exons A1 and A2) and portions of the RCK1-RCK2 linker (exons B0, B1, B2, C0, and C1). Exons A1 and A2 are used in a mutually exclusive manner and are 67% identical. The other exons can extend the RCK1-RCK2 linker by up to 41 residues. Electrophysiological recordings of all isoforms show that the A1 and A2 exons regulate activation kinetics and Ca(2+) sensitivity, but only if alternate exons are inserted at site B or C. Thus, RCK1 interacts with the RCK1-RCK2 linker, and the effect of exon variation on gating depends on the combination of alternate exons present in each isoform.

The temporal dynamics of two response-focused forms of emotion regulation: experiential, expressive, and autonomic consequences.

This study examines the early affective consequences of two close forms of suppression. Participants (N=37) were shown negative, positive, and neutral pictures and cued either to attend to the pictures, or to perform expressive or physiological suppression (i.e., reduce body reactions). Continuous measures of experience, expressivity, and autonomic responses showed that both suppression strategies produced rapid response modulation. Common effects of the two strategies included a transient increase in negative feeling, a durable decrease in positive feeling, and a decrease in expressivity, cardiovascular activity, and oxygenation. The two strategies were significantly different only in response to positive stimuli, with physiological suppression showing a larger decrease in experience intensity and blood pressure. These results suggest a strong overlap between the two suppression strategies in terms of their early impact on emotional responses.

The Geneva affective picture database (GAPED): a new 730-picture database focusing on valence and normative significance.

In emotional research, efficient designs often rely on successful emotion induction. For visual stimulation, the only reliable database available so far is the International Affective Picture System (IAPS). However, extensive use of these stimuli lowers the impact of the images by increasing the knowledge that participants have of them. Moreover, the limited number of pictures for specific themes in the IAPS database is a concern for studies centered on a specific emotion thematic and for designs requiring a lot of trials from the same kind (e.g., EEG recordings). Thus, in the present article, we present a new database of 730 pictures, the Geneva Affective PicturE Database, which was created to increase the availability of visual emotion stimuli. Four specific negative contents were chosen: spiders, snakes, and scenes that induce emotions related to the violation of moral and legal norms (human rights violation or animal mistreatment). Positive and neutral pictures were also included: Positive pictures represent mainly human and animal babies as well as nature sceneries, whereas neutral pictures mainly depict inanimate objects. The pictures were rated according to valence, arousal, and the congruence of the represented scene with internal (moral) and external (legal) norms. The constitution of the database and the results of the picture ratings are presented.

Neuronal processes involved in subjective feeling emergence: oscillatory activity during an emotional monitoring task.

Subjective feeling, defined as the conscious experience of emotion and measured by self-report, is generally used as a manipulation check in studying emotional processes, rather than being the primary focus of research. In this paper, we report a first investigation into the processes involved in the emergence of a subjective feeling. We hypothesized that the oscillatory brain activity presumed to underlie the emergence of a subjective feeling can be measured by electroencephalographic (EEG) frequency band activity, similar to what has been shown in the literature for the conscious representation of objects. Emotional reactions were induced in participants using static visual stimuli. Episodes for which participants reported a subjective feeling were compared to those that did not lead to a conscious emotional experience, in order to identify potential differences between these two kinds of reactions at the oscillatory level. Discrete wavelet transforms of the EEG signal in gamma (31-63 Hz) and beta (15-31 Hz) bands showed significant differences between these two types of reactions. In addition, whereas beta band activities were widely distributed, differences in gamma band activity were predominantly observed in the frontal and prefrontal regions. The results are interpreted and discussed in terms of the complexity of the processes required to perform the affective monitoring task. It is suggested that future work on coherent mental representation of multimodal reaction patterns leading to the emergence of conscious emotional experience should include modifications in the time window examined and an extension of the frequency range to be considered.
