The time course of positive and negative emotion in dysphoria

Prior research has demonstrated attenuated reactivity to positive stimuli among depressed and dysphoric individuals, and inconsistent evidence regarding attenuated reactivity to negative stimuli. However, such research has measured experiential reactivity to emotion stimuli in one static moment, which may obscure important information regarding the time course and dynamics of emotion. The current study employed continuous measurement of experiential emotion during and following the presentation of emotion eliciting film clips. Results revealed that dysphoric individuals (n = 16), as compared to nondysphoric controls (n = 31), were equally responsive to positive and negative film clips in terms of peak reactivity during and following the clip. The most striking difference between groups was that dysphoric individuals showed a shortened time course of positive emotion. These emotion dynamics suggest that perhaps the most important aspect of positive emotion regulation in the context of depressed mood is not the inability to initially react to a positive experience, but rather the inability to maintain positive emotion. Possible underlying mechanisms of positive emotion regulation are discussed, and implications for intervention are highlighted.     

A Methodological Examination of Emotion Inductions in Borderline Personality Disorder: A Comparison of Standardized Versus Idiographic Stimuli

Emotional reactivity is conceptualized as a core feature of borderline personality disorder (BPD) and has been subject to substantial empirical research. The laboratory methods used to elicit emotional reactivity in BPD have varied and findings across studies have been mixed. At present, there is little research evaluating the relative efficacy of different methods in eliciting emotional reactivity in BPD. Thus, the current study examined differences in emotional reactivity among individuals with BPD in response to standardized and idiographic stimuli, and across three specific emotions (sadness, fear, and anger). Individuals with BPD, social anxiety disorder, and healthy controls viewed film clips (i.e., standardized stimuli) or engaged in a personally-relevant imagery task (i.e., idiographic stimuli) while self-reported and physiological indices (skin conductance response and respiratory sinus arrhythmia) of emotion were collected. Results indicated that BPD participants displayed greater reactivity of sadness and anger (but not fear) in response to the idiographic versus standardized stimuli, a pattern that was not exhibited by the other two groups. These findings might explain some of the mixed evidence to date and suggest that idiographic sadness and fear inductions may be more effective for individuals with BPD.     

No pain,no change: Reductions in prior negative affect following physical pain

In general, organisms are motivated to avoid stimuli that induce pain. However, some individuals intentionally inflict pain on themselves (e.g., nonsuicidal self-injury) and report doing so for the perceived emotional benefits following the experience of pain. Two controlled laboratory studies sought to expand upon the relatively limited literature on the effects of pain on emotion. In Study 1, participants provided momentary affect ratings immediately before and after experiencing physical pain. Results demonstrated that both positive affect and negative affect (NA) decreased following the experience of pain. In the Study 2, we examined the effect that individual differences in emotional reactivity had on affective reactions to pain. Individuals high in emotional reactivity experienced larger decreases in NA following the experience of pain than individuals who were low in emotional reactivity. Our findings may potentially explain why some individuals intentionally seek out the experience of pain.     

Amygdala responses to emotionally valenced stimuli in older and younger adults

Abstract— As they age, adults experience less negative emotion, come to pay less attention to negative than to positive emotional stimuli, and become less likely to remember negative than positive emotional materials. This profile of findings suggests that, with age, the amygdala may show decreased reactivity to negative information while maintaining or increasing its reactivity to positive information. We used event-related functional magnetic resonance imaging to assess whether amygdala activation in response to positive and negative emotional pictures changes with age. Both older and younger adults showed greater activation in the amygdala for emotional than for neutral pictures; however, for older adults, seeing positive pictures led to greater amygdala activation than seeing negative pictures, whereas this was not the case for younger adults.     

不同抑郁症状青少年调节不同强度情绪时策略选择的差异

最新研究发现,情绪强度会影响健康个体的情绪调节策略选择。然而,至今尚未有研究考察情绪强度对不同抑郁症状青少年策略选择的影响。对此,本研究通过流调中心用抑郁量表划分出无抑郁、阈下抑郁和抑郁症青少年,进而考察其在面对高-低强度积极-消极日常情绪事件时选择认知重评和认知沉浸的差异。结果发现：当面对高强度积极情绪、低强度积极情绪和低强度消极情绪时,三组被试的策略选择均无显著差异;当面对高强度消极情绪时,无抑郁青少年比阈下抑郁和抑郁症青少年更多选择认知重评而更少选择认知沉浸,但阈下抑郁和抑郁症青少年之间无显著差异。结果表明：不同抑郁症状青少年在面对不同强度和效价情绪时的情绪调节策略选择存在差异,表现为高强度消极情绪下抑郁症状越多的青少年越少选择认知重评而越多选择认知沉浸。这一发现有助于识别和干预青少年的抑郁症状。     

Mood induced cognitive and emotional reactivity, life stress, and the prediction of depressive relapse

This study examined a group of participants who were fully remitted from a previous episode of major depressive disorder, and evaluated the role of cognitive and emotional reactivity to a mood challenge, and life stress in the prediction of relapse. Fifty-two participants were evaluated during remission, and their reactivity (i.e., change in dysfunctional attitudes and emotional state) to a depressed mood induction was evaluated. The cohort was followed up 12 months after the initial assessment. Thirty-five percent of the sample experienced a relapse during the follow-up period. Relapse was predicted by higher rates of life stress, and lower levels of emotional reactivity (specifically less reduction in happiness) to the mood induction during the initial assessment. Cognitive reactivity to the mood induction did not predict relapse, nor did the interaction between cognitive reactivity and life stress. These findings are discussed in terms of recent literature suggesting that depression is associated with insensitivity to emotion context, such that depressed individuals display blunted emotional responses to affective stimuli, including sadness-inducing stimuli. These findings suggest that insensitivity to emotional context may also be a characteristic of euthymic individuals at risk of relapse.     

Individual differences in hedonic capacity,depressed mood,and affective states predict emotional reactivity

Identifying factors that contribute to inter-individual differences in emotional reactivity is central to understanding the basic mechanisms that give rise to adaptive emotion reactivity and to disruptions that may occur in psychopathology. The current study related emotional reactivity in an unselected young adult sample (N?=?101) to individual difference factors relevant to emotional functioning and mood pathology, specifically anhedonia, depressed mood, and current affective state. To assess emotional reactivity, participants rated their emotional responses to 100 pictures from the International Affective Picture System. Increased self-reported anhedonia (i.e. reduced hedonic capacity) predicted blunted emotional reactivity to both positive and negative images, relative to neutral images, while elevated depressed mood predicted potentiated emotional reactivity to negative vs. neutral images. Anhedonia also accounted for far greater variance in emotional reactivity than depressed mood. Further, more positive affective state predicted potentiated reactivity to positive versus neutral images while more negative affective state predicted potentiated reactivity to negative versus neutral images beyond effects of anhedonia and depressed mood. The current study identified separable effects of anhedonia, depressed mood, and current affect on emotional reactivity.     

Mindful attention predicts greater recovery from negative emotions,but not reduced reactivity

This study investigated the role of dispositional mindful attention in immediate reactivity to, and subsequent recovery from, laboratory-induced negative emotion. One hundred and fourteen undergraduates viewed blocks of negative pictures followed by neutral pictures. Participants’ emotional responses to negative pictures and subsequent neutral pictures were assessed via self-reported ratings. Participants’ emotional response to negative pictures was used to index level of emotional reactivity to unpleasant stimuli; emotional response to neutral pictures presented immediately after the negative pictures was used to index level of emotional recovery from pre-induced negative emotion (residual negativity). Results indicated that mindful attention was not associated with the emotional response to negative pictures, but it was associated with reduced negative emotion in response to the neutral pictures presented immediately after the negative pictures, suggesting better recovery as opposed to reduced reactivity. This effect was especially pronounced in later experimental blocks when the accumulation of negative stimuli produced greater negative emotion from which participants had to recover. The current study extends previous findings on the relationship between dispositional mindfulness and reduced negative emotion by demonstrating that mindful attention may facilitate better recovery from negative emotion, possibly through more effective disengagement from previous stimuli.     

Impact of depression on response to comedy: a dynamic facial coding analysis

Individuals suffering from depression show diminished facial responses to positive stimuli. Recent cognitive research suggests that depressed individuals may appraise emotional stimuli differently than do nondepressed persons. Prior studies do not indicate whether depressed individuals respond differently when they encounter positive stimuli that are difficult to avoid. The authors investigated dynamic responses of individuals varying in both history of major depressive disorder (MDD) and current depressive symptomatology (N = 116) to robust positive stimuli. The Facial Action Coding System (Ekman & Friesen, 1978) was used to measure affect-related responses to a comedy clip. Participants reporting current depressive symptomatology were more likely to evince affect-related shifts in expression following the clip than were those without current symptomatology. This effect of current symptomatology emerged even when the contrast focused only on individuals with a history of MDD. Specifically, persons with current depressive symptomatology were more likely than those without current symptomatology to control their initial smiles with negative affect-related expressions. These findings suggest that integration of emotion science and social cognition may yield important advances for understanding depression.     

A preliminary investigation of cognitive flexibility for emotional information in major depressive disorder and non-psychiatric controls

Clinical research suggests that individuals with major depressive disorder (MDD) are cognitively inflexible, exhibiting ruminative, rigid, and automatic thoughts within a negative schema. However, existing neuropsychological research on cognitive flexibility in this population has not employed emotional stimuli. Because research suggests that the performance of individuals with MDD is modulated when emotional stimuli are used, this study investigates the impact of emotional stimuli on cognitive flexibility performance through a novel emotional modification of the Wisconsin Card Sorting Test. Controls were less flexible when stimuli were positive and individuals with MDD were less flexible when stimuli were negative relative to the controls. These divergent styles of responding to emotional information may contribute to the relative risk or protection from depressed mood.     

Time course of selective attention in clinically depressed young adults: an eye tracking study

Depressed individuals display biased attention for emotional information when stimuli are presented for relatively “long” (e.g., 1 s) durations. The current study examined whether attentional biases are sustained over a much longer period. Specifically, clinically depressed and never depressed young adults simultaneously viewed images from four emotion categories (sad, threat, positive, neutral) for 30 s while line of visual gaze was assessed. Depressed individuals spent significantly more time viewing dysphoric images and less time viewing positive images than their never depressed counterparts. Time course analyses indicated that these biases were maintained over the course of the trial. Results suggest that depressed participants' attentional biases for dysphoric information are sustained for relatively long periods even when other emotional stimuli are present. Mood congruent information-processing biases appear to be a robust feature of depression and may have an important role in the maintenance of the disorder.     

A discrete emotions approach to positive emotion disturbance in depression

Converging findings suggest that depressed individuals exhibit disturbances in positive emotion. No study, however, has ascertained which specific positive emotions are implicated in depression. We report two studies that compare how depressive symptoms relate to distinct positive emotions at both trait and state levels of assessment. In Study 1 (N=185), we examined associations between depressive symptoms and three trait positive emotions (pride, happy, amusement). Study 2 compared experiential and autonomic reactivity to pride, happy, and amusement film stimuli between depressive (n=24; DS) and non-depressive (n=31; NDS) symptom groups. Results indicate that symptoms of depression were most strongly associated with decreased trait pride and decreased positive emotion experience to pride-eliciting films. Discussion focuses on the implications these findings have for understanding emotion deficits in depression as well as for the general study of positive emotion.     

Idiographic autobiographical memories in major depressive disorder

When cued with generic happy and sad words, depressed individuals have been found to articulate contextually impoverished, overgeneral memories of both positive and negative autobiographical events. The current study tested whether overgeneral memory is observed outside of the cue-word paradigm. Currently depressed, formerly depressed, and never-depressed controls underwent an idiographic interview procedure in which participants generated memories of their happiest and saddest lifetime events. Although depressed and nondepressed participants did not differ with respect to the specificity, retrieval difficulty, and emotionality of their saddest memories, depressed individuals' happiest memories were less specific, harder to retrieve, and less emotional than were nondepressed participants' happiest memories. The memory characteristics of formerly depressed participants largely resembled those of healthy controls. Overall, the present results suggest that meaningful cues trigger mood-congruent memory processing in currently, but not in formerly, depressed individuals.     

Associations between serotonin transporter gene promoter region (5-HTTLPR) polymorphism and gaze bias for emotional information

The serotonin transporter promoter region polymorphism (5-HTTLPR) is associated with neural response to negative images in brain regions involved in the experience of emotion. However, the behavioral implications of this sensitivity have been studied far less extensively. The current study used eye-tracking methodology to examine how individuals genotyped for the 5-HTTLPR, including the single nucleotide polymorphism (SNP) rs25531, allocated attention during prolonged (30-s) exposure to face stimuli depicting positive and negative emotion. Short 5-HTTLPR allele carriers and carriers of the long allele with guanine at the sixth nucleotide (S/LG) displayed a stronger gaze bias (total fixation time, number of fixations, mean fixation length) for positive than for sad, threat, or neutral stimuli. In contrast, those homozygous for the long 5-HTTLPR allele with adenine at the sixth nucleotide (LA) viewed the emotion stimuli in an unbiased fashion. Time course analyses indicated no initial 5-HTTLPR group differences; however, S/LG 5-HTTLPR allele carriers were more likely than LA 5-HTTLPR homozygotes to direct gaze toward happy than toward sad stimuli over time. This bias toward positive stimuli during the later stages of information processing likely reflects a strategic effort to downregulate heightened reactivity to negative stimuli among 5-HTTLPR S/LG allele carriers.     

The effect of cognitive reappraisal on long‐term emotional experience and emotional memory

One's ability to properly regulate emotion is critical to psychological and physical well‐being. Among various strategies to regulate emotion, cognitive reappraisal has been shown to modulate both emotional experience and emotional memory. However, most studies of reappraisal have focused on reappraisal of negative situations, with reappraisal of positive emotion receiving considerably less attention. In addition, the effects of reappraisal on emotional reactions to stimuli are typically only assessed either immediately or after a short delay, and it remains unclear whether reappraisal effects persist over longer time periods. We investigated the effect of cognitive reappraisal on emotional reactions and long‐term episodic memory for positive and negative stimuli. Men and women viewed emotionally negative, positive, and neutral pictures while they were instructed to either increase, decrease, or maintain the initial emotional reactions elicited by the pictures. Subjective ratings of emotional valence and arousal were assessed during the regulation task and again after 1 week. Memory for the pictures was assessed with free recall. Results indicated that pictures accompanied by instructions to increase emotion were better recalled than pictures reappraised to decrease emotion. Modulation of emotional arousal elicited by stimuli persisted over a week, but this effect was observed only for men. These findings suggest that cognitive reappraisal can have long‐lasting effects on emotional reactions to stimuli. However, the sex differences observed for the effects of reappraisal on emotional reactions highlight the importance of considering individual differences in the effects of regulation.

Discussion focuses on the implications these findings have for understanding emotion deficits in depression as well as for the general study of positive emotion.     

Visual complexity attenuates emotional processing in psychopathy: Implications for fear-potentiated startle deficits

A long-standing debate is the extent to which psychopathy is characterized by fundamental deficits in attention or emotion. We tested the hypothesis that the interplay of emotional and attentional systems is critical for understanding processing deficits in psychopathy. A group of 63 offenders were assessed using the Psychopathy Checklist: Screening Version. Event-related brain potentials (ERPs) and fear-potentiated startle (FPS) reflexes were collected while participants viewed pictures selected to disentangle an existing confound between perceptual complexity and emotional content in the pictures typically used to study fear deficits in psychopathy. As predicted, picture complexity moderated the emotional processing deficits. Specifically, the affective–interpersonal features of psychopathy were associated with greater allocation of attentional resources to processing emotional stimuli at initial perception (visual N1), but only when the picture stimuli were visually complex. Despite this, results for the late positive potential indicated that emotional pictures were less attentionally engaging and held less motivational significance for individuals high in affective–interpersonal traits. This deficient negative emotional processing was observed later in their reduced defensive fear reactivity (FPS) to high-complexity unpleasant pictures. In contrast, the impulsive–antisocial features of psychopathy were associated with decreased sensitivity to picture complexity (visual N1) and were unrelated to emotional processing, as assessed by both ERPs and FPS. These findings are the first to demonstrate that picture complexity moderates FPS deficits, and they implicate the interplay of attention and emotional systems as deficient in psychopathy.

The experience of positive emotion is associated with the automatic processing of positive emotional words

The current study examines the relationship between attention bias for positive emotional words and self-reported emotional experience. Previous research suggests that the experience of positive emotion momentarily broadens cognitive processes, potentially allowing individuals to build an array of enduring personal resources. However, it is unknown whether the experience of positive emotion also broadens emotional information processing. Participants included 60 healthy undergraduate students who completed measures of psychopathology, self-reported emotional experience, and an emotional Stroop task designed to measure attentional bias to positive and negative emotional information. Results indicate significant associations between reaction times for high-intensity happiness words and self-reported high levels of positive emotion and low levels of negative emotions. These associations were not present for low intensity happiness words. Findings suggest that individuals who experience high levels of positive emotion and low levels of negative emotion demonstrate an attention bias for positive information and, from an information processing perspective, provide insight into the manner in which positive emotions broaden cognitive processes.     

Turn down the volume or change the channel? Emotional effects of detached versus positive reappraisal

Cognitive reappraisal, or changing one's interpretation of an event in order to alter the emotional response to it, is thought to be a healthy and an effective emotion regulation strategy. Although researchers recognize several distinct varieties of reappraisal, few studies have explicitly compared the effects of multiple reappraisal strategies on emotional responding. The present study compares the effects of detached and positive reappraisal on thought content, subjective emotional experience, physiological reactivity, and facial expressions of emotion while viewing film clips evoking sadness and disgust. Although both forms of reappraisal reduced overall emotional responding to unpleasant stimuli, the effects of detached reappraisal were stronger in this regard, and positive reappraisal was more likely to maintain subjective experience and facial expression of stimulus-appropriate positive emotions. The two reappraisal strategies also produced somewhat different profiles of physiological responding. Differences between detached and positive reappraisal with respect to subjective experience and facial expression were more pronounced among men than women; the reverse was true for differences with respect to physiological responding. Beyond these effects on individual emotion response systems, detached and positive reappraisal also had somewhat different effects on coherence in change across response systems. Implications for our understanding of emotion regulation processes, and for emotion theory more broadly, are discussed. (PsycINFO Database Record (c) 2012 APA, all rights reserved).
