Positive emotion regulation in emotional disorders: A theoretical review

Conceptualizations of emotion regulation have led to the identification of cognitive and behavioral regulatory abnormalities that contribute to the development and maintenance of emotional disorders. However, existing research on emotion regulation in anxiety and mood disorders has primarily focused on the regulation of negative emotions rather than positive emotions. Recent findings indicate that disturbances in positive emotion regulation occur across emotional disorders, and may be a generative target for treatment research. The aims of this paper are to: 1. Present a transdiagnostic model of positive emotion disturbances in emotional disorders; 2. Review evidence for disturbances in positive emotion regulation in emotional disorders across categories of emotion regulation; and 3. Propose treatment strategies that may address these disturbances.     

How we think about cognition, emotion, and biology in psychopathology

The variety of potential relationships assumed between psychological and biological concepts fosters considerable misunderstanding of what our data can tell us. A naively reductionistic view of psychological concepts is prevalent, particularly in the psychopathology literature. A series of examples of the application of psychophysiological methods in studies of cognition, emotion; and psychopathology provides a background for a discussion of these problems. Unwarranted distinctions between cognition and emotion, between classes of measures, and between psychological and biological approaches to understanding normal functioning and psychopathology undermine the ability of cognitive neuroscience to achieve its considerable potential. A nondualistic, nonreductionistic, noninteractive relationship is recommended, with psychological and biological concepts both having central, necessary, and distinct roles.     

Whether, how, and when social anxiety shapes positive experiences and events: a self-regulatory framework and treatment implications

Although neglected in diagnostic criteria lists, theoretical models, and treatment approaches, attenuated positive emotions and cognitions distinguish social anxiety and social anxiety disorder from other anxiety conditions (and cannot be accounted for by comorbidity with depression). We present a self-control resource depletion model to explain how the intense self-regulatory efforts of high socially anxious individuals dampen positive experiences and events. We review existing research on individuals with social anxiety difficulties, focusing on impoverished positive experiences and quality of life, atypical reactions to overtly positive social outcomes, the absence of a normative bias toward the positive in social situations, and a meaningful subset of individuals who show signs of impulsive, short-lived positive events. We also discuss findings from the social psychology literature for how to enhance positive experiences, positive events, and self-regulatory capacity in individuals with social anxiety difficulties. The aim of the review is to broaden theory, research, and treatment efforts to the positive spectrum of human functioning.

What goes up can come down? A preliminary investigation of emotion reactivity and emotion recovery in bipolar disorder

Background

How is emotion disrupted in bipolar disorder? Two studies are presented that adopt a multi-method approach to investigate emotion reactivity and emotion recovery in bipolar I disorder.

Methods

Across both studies, individuals with inter-episode bipolar disorder and healthy controls were shown three emotion-eliciting films (neutral, happy, and sad) and experiential and physiological responses were measured. In Study 1, bipolar (BD; n = 23) and non-clinical control (NC; n = 24) participants' emotional reactivity during film clips was assessed. In Study 2, a separate sample of BD (n = 23) and NC (n = 25) participants' emotion recovery was assessed after the film clips were assessed.

Results

Results indicated that the BD group exhibited increased self-reported positive emotion and respiratory sinus arrhythmia across all films compared to the NC group. There were no group differences in emotion recovery.

Discussion

Taken together, these results suggest that bipolar disorder is associated with increased positive emotion reactivity, but not emotion recovery, across contexts.     

The temporal dynamics of cognitive reappraisal: Cardiovascular consequences of downregulation of negative emotion and upregulation of positive emotion

This study examines the effects of cognitive reappraisal on the cardiovascular response to affective stimuli. Participants (N = 53) were shown affective images and were asked either to attend to the images, or to downregulate negative affect through reappraisal of negative images or upregulate positive affect through reappraisal of positive images while continuous measures of cardiovascular activity were recorded. Reappraisal of negative images was associated with lower total peripheral resistance and larger cardiac output in the prestimulus period, whereas reappraisal of positive images was associated with less pronounced decreases of heart rate, cardiac output, and mean blood pressure in the viewing period as compared to unregulated conditions. The results indicate that cognitive reappraisal engenders adaptive hemodynamic profiles both during anticipation and during viewing of affective images depending on their valence and the regulatory goal.     

Effect of positive and negative emotion on stimulus-preceding negativity prior to feedback stimuli

Stimulus-preceding negativity (SPN) was recorded to investigate the effect of positive and negative emotion on the SPN preceding feedback stimuli. In the time-estimation task in which an acoustic stimulus was presented 3 s after a voluntary movement, (1) the negative valence (aversive band noise and pure tone) and (2) the positive valence (reward and no-reward) of feedback stimuli were manipulated. During noise conditions, participants received the band noise as a feedback stimulus except when their time estimations were accurate. They received a monetary reward for accurate time estimations under the reward conditions. The prefeedback SPN was larger under reward than no-reward conditions. In addition, the prefeedback SPN in the noise condition was larger compared with the pure tone condition. Our results appear to suggest that emotional anticipation is important in eliciting the prefeedback SPN.     

Association with positive outcome induces early effects in event-related brain potentials

Emotional pictures, faces, or words elicit an early posterior negativity (EPN) in the event-related potential, starting around 200-400 ms, followed by a late positive complex (LPC). Occasionally, also very early effects of emotion (VEEEs) are seen prior to 200 ms. The present study examined whether VEEEs can be due to direct links established by reinforcement learning. In the learning session, participants learned to associate previously unknown Chinese words with monetary gain, loss, or neither. In the test session, they were required to distinguish the learned stimuli from novel distracters. Specific to stimuli associated with positive outcome a VEEE, consisting of a posterior positivity, appeared around 150 ms and an LPC between 550 and 700 ms, whereas an EPN was absent. These results show that previous association with reward can induce VEEEs, indicating that emotion effects in ERPs may arise in the absence of biologically preparedness and semantic meaning.     

The role of asymmetric frontal cortical activity in emotion-related phenomena: A review and update

Conceptual and empirical approaches to the study of the role of asymmetric frontal cortical activity in emotional processes are reviewed. Although early research suggested that greater left than right frontal cortical activity was associated with positive affect, more recent research, primarily on anger, suggests that greater left than right frontal cortical activity is associated with approach motivation, which can be positive (e.g., enthusiasm) or negative in valence (e.g., anger). In addition to reviewing this research on anger, research on guilt, bipolar disorder, and various types of positive affect is reviewed with relation to their association with asymmetric frontal cortical activity. The reviewed research not only contributes to a more complete understanding of the emotive functions of asymmetric frontal cortical activity, but it also points to the importance of considering motivational direction as separate from affective valence in psychological models of emotional space.     

Spontaneous EEG activity and spontaneous emotion regulation

Variability in both frontal and parietal spontaneous EEG activity, using α and β band power and θ/β and δ/β ratios, was explored in a sample of 96 healthy volunteers as a potential correlate of individual differences in spontaneous emotion regulation (SER). Following a baseline EEG recording, participants were asked to continuously rate their discomfort while looking at affective pictures, as well as for a period of time after exposure. Greater spontaneous β band power in parietal locations, lower frontal and parietal δ/β ratios, and lower parietal θ/β ratio were associated with lower ratings of discomfort after the offset of unpleasant pictures. Moreover, lower parietal δ/β ratio was also related to less time needed to recover from discomfort after exposure to aversive pictures, while only a greater frontal and parietal α band power appeared to be associated with faster recovery from discomfort induced by normative-neutral pictures. However, parietal δ/β ratio was the only predictor of both minimum discomfort ratings and time needed to downregulate following exposure to unpleasant pictures, and frontal α band power the only spontaneous EEG index that predicted variability in spontaneous down-regulation after the exposure to normative-neutral pictures. Results are discussed focusing on the utility of diverse spontaneous EEG measures in several cortical regions when capturing trait-like individual differences in emotion regulation capabilities and processes.     

The effect of sleep deprivation and restriction on mood,emotion, and emotion regulation: three meta-analyses in one

Study ObjectivesNew theory and measurement approaches have facilitated nuanced investigation of how sleep loss impacts dimensions of affective functioning. To provide a quantitative summary of this literature, three conceptually related meta-analyses examined the effect of sleep restriction and sleep deprivation on mood, emotion, and emotion regulation across the lifespan (i.e. from early childhood to late adulthood).MethodsA total of 241 effect sizes from 64 studies were selected for inclusion, and multilevel meta-analytic techniques were used when applicable.ResultsThere was a moderate, positive effect of sleep loss on negative mood (g = 0.45), which was stronger for studies with younger samples, as well as a large, negative effect of sleep loss on positive mood (g = −0.94). For negative mood only, studies that used total sleep deprivation had larger effect sizes than studies that restricted sleep. After correcting for publication bias, a modest but significant negative effect for sleep loss on emotion (g = −0.11) was found; the valence of emotional stimuli did not change the direction of this effect, and type of sleep manipulation was also not a significant moderator. Finally, sleep restriction had a small, negative effect on adaptive emotion regulation (g = −0.32), but no significant impact on maladaptive emotion regulation (g = 0.14); all studies on adaptive emotion regulation were conducted with youth samples.ConclusionsSleep loss compromises optimal affective functioning, though the magnitude of effects varies across components. Findings underscore the importance of sleep for healthy affective outcomes.     

The role of asymmetrical frontal cortical activity in aggression

Aggression correlates with relatively greater left than right frontal electroencephalographic activity (inverse of EEG alpha power). The present experiment extends this research by manipulating frontal asymmetry and examining its effect on aggression. Participants were assigned to increase left frontal activation or increase right frontal activation by contracting their contralateral hand. They then received insulting feedback and played a game in which they could aggress toward the person who insulted them. Right-hand contractions caused greater left than right central and frontal activation and aggression as compared to left-hand contractions. Within the right-hand contraction condition, greater relative left frontal activity was associated with greater aggression.     

Upward spirals of positive emotions counter downward spirals of negativity: Insights from the broaden-and-build theory and affective neuroscience on the treatment of emotion dysfunctions and deficits in psychopathology

This review integrates Fredrickson's broaden-and-build theory of positive emotions with advances in affective neuroscience regarding plasticity in the neural circuitry of emotions to inform the treatment of emotion deficits within psychopathology. We first present a body of research showing that positive emotions broaden cognition and behavioral repertoires, and in so doing, build durable biopsychosocial resources that support coping and flourishing mental health. Next, by explicating the processes through which momentary experiences of emotions may accrue into self-perpetuating emotional systems, the current review proposes an underlying architecture of state-trait interactions that engenders lasting affective dispositions. This theoretical framework is then used to elucidate the cognitive–emotional mechanisms underpinning three disorders of affect regulation: depression, anxiety, and schizophrenia. In turn, two mind training interventions, mindfulness and loving-kindness meditation, are highlighted as means of generating positive emotions that may counter the negative affective processes implicated in these disorders. We conclude with the proposition that positive emotions may exert a countervailing force on the dysphoric, fearful, or anhedonic states characteristic of psychopathologies typified by emotional dysfunctions.     

P3b reflects maltreated children's reactions to facial displays of emotion

Processing of emotion information by maltreated and control children was assessed with event-related brain potentials (ERPs). Maltreated children, for whom negative facial displays may be especially salient, and demographically comparable peers were tested to increase knowledge of differential processing of emotion information. ERPs were measured while children responded to pictures depicting facial displays of anger, fear, and happiness. Maltreated children showed larger P3b amplitude when angry faces appeared as targets than did control children; the two groups did not differ when targets were either happy or fearful facial expressions or for nontargets of any emotional content. These results indicate that aberrant emotional experiences associated with maltreatment may alter the allocation of attention and sensitivity that children develop to process specific emotion information.     

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 role of presleep negative emotion in sleep physiology

Although daytime emotional stressful events are often presumed to cause sleep disturbances, the few studies of stressful life events on sleep physiology have resulted in various and contradictory findings. As research has focused in particular on stress in itself, the present study is the first to investigate the effect using polysomnography (PSG). Results indicate a significant increase in sleep fragmentation, as expressed by decreased sleep efficiency, total sleep time, percentage of rapid eye movement (REM) sleep, and an increased wake after sleep onset latency, total time awake, latency to SWS, number of awakenings and number of awakenings from REM sleep. The results demonstrate that negative emotion correlates with enhanced sleep fragmentation helping us to understand why sleep patterns change and how sleep disturbances may develop.     

General psychopathology in anorexia nervosa: the role of psychosocial factors

The aim of the present study was to investigate psychosocial correlates of comorbid psychopathology. Data were collected from a total of 90 female inpatients with anorexia nervosa (AN). Higher levels of general psychopathology were detected in depression, interpersonal sensitivity, obsessive-compulsive and anxiety subscales of the Symptom Checklist (SCL)-90. Regression analysis also revealed that higher levels of psychopathology across SCL-90 subscales in AN patients are significantly associated with an earlier age of onset of the condition, higher levels of anorectic psychopathology as measured by Eating Disorders Examination, lower self-esteem as measured by Multidimensional Self-Esteem Inventory and social support levels as measured by Quality of Social Network and Social Support Questionnaire. Considering the high levels of general psychopathology in people with AN, routine clinical practice should aim for a comprehensive assessment of such. Given the strong association between psychosocial factors such as self-esteem, social support and general psychopathology, psychological therapies could play an important role in facilitating emotional recovery.
