Expressive Writing and Marital Satisfaction: A Writing Sample Analysis

ObjectiveTo examine the relationship between marital satisfaction and two linguistic elements in the context of writing: use of personal pronouns and affective language.BackgroundExpressive writing (EW) is an effective way of identifying and processing thoughts and emotions. It also promotes individual, physical, and psychological health. However, much less literature has examined the relationship between EW and relationship health.MethodWe used the Linguistic Inquiry and Word Count (LIWC2007) to examine the writing of 78 married, heterosexual couples who were instructed to write freely on a topic they felt strongly about in their relationship. Multilevel modeling within SPSS was used to examine our research questions.ResultsFindings suggest a relationship between marital satisfaction and use of (a) first‐person plural pronouns (we, us, our, ours), (b) positive affective language, and (c) linguistic indicators of anger when writing about one's relationship.ConclusionThe results provide further impetus for examining relationship processes within an EW framework and, in particular, for examining the merits of EW as a potential intervention for couples.ImplicationsFindings suggest that expressive writing may be a potentially important indicator of mutuality (we‐ness), the ability to up‐regulate positive emotion, and negative affective processes (i.e., anger).

Mindfulness-oriented recovery enhancement reduces opioid misuse risk via analgesic and positive psychological mechanisms: A randomized controlled trial.

Despite the heightened urgency of the current prescription opioid crisis, few psychotherapies have been evaluated for chronic pain patients receiving long-term opioid analgesics. Current psychological pain treatments focus primarily on ameliorating negative affective processes, yet basic science suggests that risk for opioid misuse is linked with a dearth of positive affect. Interventions that modulate positive psychological processes may produce therapeutic benefits among patients with opioid-treated chronic pain. The aim of this study was to conduct a theory-driven mechanistic analysis of proximal outcome data from a Stage 2 randomized controlled trial of Mindfulness-Oriented Recovery Enhancement (MORE), an integrative intervention designed to promote positive psychological health. Patients with opioid-treated chronic pain (N = 95; age = 56.8 ± 11.7; 66% female) were randomized to 8 weeks of therapist-led MORE or support group (SG) interventions. A latent positive psychological health variable comprised of positive affect, meaning in life, and self-transcendence measures was examined as a mediator of the effect of MORE on changes in pain severity at posttreatment and opioid misuse risk by 3-month follow-up. Participants in MORE reported significantly greater reductions in pain severity by posttreatment (p = .03) and opioid misuse risk by 3-month follow-up (p = .03) and significantly greater increases in positive psychological health (p < .001) than SG participants. Increases in positive psychological health mediated the effect of MORE on pain severity by posttreatment (p = .048), which in turn predicted decreases in opioid misuse risk by follow-up (p = .02). Targeting positive psychological mechanisms via MORE and other psychological interventions may reduce opioid misuse risk among chronic pain patients receiving long-term opioid therapy.

Inauthentic self-presentation on facebook as a function of vulnerable narcissism and lower self-esteem

This study was the first to delineate the role of grandiose narcissism and vulnerable narcissism, in addition to self-esteem and self-monitoring, in predicting authentic self-presentation on Facebook. Facebook users (N = 155) answered questions about their personality as well as the persona they present on Facebook, and Euclidean distances quantified the congruence between the two personas. Self-monitoring (ability to modify self-presentation) was included as a control variable in regression analysis. As hypothesised, grandiose narcissism predicted more congruent presentation between the true self and the Facebook self, while vulnerable narcissism predicted a greater difference between the two personas. In contrast to predictions, self-esteem was not associated with congruence between the two selves; however, a follow-up moderation analysis revealed a significant self-esteem—vulnerable narcissism interaction. Specifically, for individuals with average and low levels of self-esteem, there is more incongruence between the true self and the Facebook self as a function of increased vulnerable narcissism. Given the psychological benefits associated with authentic self-presentation on Facebook, these findings inform understanding of the negative affective processes of vulnerable narcissists and their self-presentation on this popular social networking medium.

Invalidation Experiences Among Non-Binary Adolescents

Mental health disparities among transgender adolescents are well documented and have generally been attributed to minority stress. However, significantly less is known about the minority stress experiences of non-binary adolescents or those who do not identify as exclusively male or female. This study qualitatively explored the unique ways that non-binary adolescents experience minority stress and how it influences their mental health and well-being. Lifeline methodology and photo elicitation were used to interview 14 ethnically diverse non-binary adolescents between the ages of 16 and 20, residing in New York City (NYC) and the San Franscicso Bay Area (SFBA). We present participants’ experiences using a novel construct of invalidation, defined as the refusal to accept one’s identity as real or true. Our findings indicate that invalidation is conceptually distinct from the established minority stressor of “non-affirmation.” Non-binary adolescents experienced myriad forms of invalidation within multiple social contexts, which contributed to negative affective and cognitive processes, including confusion, self-doubt, rumination, and internalized shame. For many participants, the cumulative stressors related to invalidation contributed to poor mental health outcomes. Data from this study suggest that identity invalidation is a unique form of minority stress that may especially affect non-binary individuals, with significant implications for their social and emotional well-being.

Central nervous system signatures of affect in asthma: associations with emotion-induced bronchoconstriction, airway inflammation, and asthma control.

The effects of asthma on affect have been noted for some time, but little is known about associated brain processes. We therefore examined whether emotion-induced bronchoconstriction, airway inflammation, and asthma control are related to specific patterns of brain activity during processing negative affective stimuli. Fifteen adults with asthma viewed alternating blocks of distressing film clips (negative condition), affectively neutral film clips (neutral condition), and a crosshair image (baseline condition) while undergoing blood oxygenation level-dependent (BOLD) functional MRI (fMRI). Block-design fMRI analysis evaluated the BOLD response to "negative-baseline" and "neutral-baseline" contrasts. Airway response to these film clips was also assessed with impulse oscillometry in a separate session. Measures of airway inflammation [fractional exhaled nitric oxide (FENO)] and asthma control [Asthma Control Questionnaire (ACQ)] were additionally obtained. A whole brain voxel-based regression analysis of contrast maps was performed against respiratory resistance increase during negative and neutral films, FENO, and ACQ. Peak airway obstruction to negative affective stimulation was associated with stronger activation of the anterior and middle cingulate gyrus, including the dorsal anterior cingulate cortex (dACC). Stronger airway inflammation and lower asthma control were associated with reduced activation to negative stimuli in the superior frontal gyrus, middle cingulate gyrus, and supplementary motor area. Activation of the dACC in negative-affect-induced airway obstruction could be part of an integrated defensive response to critical environmental change. In addition, reduced frontal and limbic activation during processing of negative affect may reflect consequences of pathophysiological processes for CNS functioning. NEW & NOTEWORTHY This functional magnetic resonance imaging study shows, for the first time, that the degree of airway constriction due to negative affective stimuli in asthma is associated with stronger response to these stimuli in the dorsal anterior and middle cingulate cortex. Asthma patients with stronger airway inflammation and reduced asthma control also show reduced activation in a number of cortical and subcortical areas relevant for affective processing and breathing control.

An Ecological Momentary Assessment of Affect, Mental Health Symptoms, and Decisions to Drink Among First-Year College Women: A Pilot Study.

College women experience more consequences (e.g., blacking out, unprotected/unwanted sex) on days when they engage in their heaviest drinking. To inform prevention efforts, research is needed to understand decision-making processes that influence women's drinking behaviors at the event level. The present study used ecological momentary assessment (EMA) methods to examine: (1) associations between positive affect (PA) and negative affect (NA) and decision-making processes on days leading up to, during, and following heavy drinking events; and (2) mental health symptoms as moderators of these associations. Female undergraduate drinkers (N = 57) completed a 14-day EMA protocol on their smartphones, which included three daily assessments of PA, NA, and willingness and intentions to drink. Trait anxiety and depressive symptoms were measured before the EMA protocol and assessed as moderators. Time-varying effect models were used to examine covariation among PA, NA, and willingness and intentions to drink on the days leading up to participants' heaviest drinking events, the day of the event itself, and the days following the event. Results revealed PA was positively associated with willingness to drink the 2days before, the day of, and the day after the heaviest drinking event. Similar effects were observed for PA and intentions to drink. Trait anxiety moderated the association between PA and intentions to drink. Findings underscore that positive affect may influence drinking-related decision-making processes surrounding heavy drinking events, particularly in those college women low in anxiety. Results identify potential entry points for real-time intervention efforts targeting college women during times of elevated PA.

The error-related negativity for error processing in interoception

The error-related negativity (ERN) is an event-related potential in the electroencephalogram (EEG) observed within the first 100 ms after commission of an error. Increased ERN amplitudes have been observed in several psychological disorders characterized by high negative affect. While the ERN has extensively been studied in tasks using exteroceptive stimuli, its relation to interoceptive stimuli is unknown. Since errors related to interoception might be particularly relevant for survival and negative affect, this study aimed to explore the ERN for errors related to interoceptive, respiratory sensations (intERN). Moreover, we compared the intERN with a commonly observed ERN related to exteroceptive, visual stimuli (extERN) and examined their associations with interoception-related negative affect. We studied the ERN using a respiratory occlusion task (intERN) and a visual flanker task (extERN) in 40 healthy volunteers during continuous 129 channel EEG recordings. In the occlusion task, participants received inspiratory occlusions of two different durations and indicated whether each occlusion was short or long. In the Flanker task, participants indicated the direction of arrowheads. Interoception-related negative affect was assessed with the Anxiety Sensitivity Index. Comparable with the extERN, the intERN was observed at fronto-central scalp positions after error commission in the occlusion task, but it peaked significantly earlier than the extERN. Mean amplitudes of the intERN and extERN showed no significant difference and were not correlated. Moreover, higher levels of anxiety sensitivity were correlated with significantly greater amplitudes of the intERN, but with lower amplitudes of the extERN. The present results firstly demonstrate an error-related negativity EEG-potential that is related to interoceptive sensations (intERN). This intERN is not associated with a commonly observed ERN elicited by exteroceptive stimuli and is distinctly linked to higher levels of interoception-related negative affect. The intERN might be a promising neural marker for future studies on interoception, negative affect and error processing.

A Systematic Review of Trials Targeting Depression and Anxiety in Patients With Delusions

Abstract. Negative affect and impaired emotion regulation skills are prevalent in patients with delusions and contribute to delusion formation and maintenance. This review evaluates existing research on interventions targeting negative affect and emotional processes as a causal mechanism on the pathway to delusions. A MEDLINE and PsycINFO search identified 7,909 articles. Five studies with randomized-controlled designs and three with uncontrolled designs met the inclusion criteria. Interventions comprised cognitive-behavioral and compassion-focused techniques. Overall, the review studies found positive intervention effects on negative affect and delusions. Where significant, controlled effect sizes ranged from small to large for negative affect and from moderate to large for delusions. Thus, existing research indicates that negative affect in patients with delusions can be modified by psychological therapy and points toward a carryover effect from the reduction of negative affect to a reduction of delusions. More large-scale randomized-controlled studies are needed to be able to draw valid conclusions on which types of interventions are most beneficial.

Pharmacological intervention and abstinence in smokers undergoing cessation treatment: A psychophysiological study

As a composite concept, negative affect comprises various aversive emotional experiences, such as irritability and nervousness. It is a critical motivational factor that helps maintain smoking behavior, and contributes significantly to smoking cessation failure as a core withdrawal symptom. Prior research has indicated an important role of nicotinic mechanisms in negative affect processing. The most effective smoking cessation medication, varenicline, targets nicotinic acetylcholine receptors (nAChRs) as a partial agonist, while another first-line cessation medication, bupropion, has shown antagonistic effects on nAChRs. Therefore, it is possible that both medications work to reduce smoking behavior through modulating negative affect processing. To evaluate this hypothesis, we examined the impact of varenicline tartrate and bupropion hydrochloride sustained-release on electrophysiological responses to affective, cigarette-related, and neutral cues before and during smoking cessation treatment in a randomized placebo-controlled clinical trial. The participants were 206 smokers, a subset of 294 participants that were enrolled in a larger smoking cessation clinical trial who were randomly assigned to one medication group for 12weeks. Orbicularis oculi (startle eyeblink response) and corrugator supercilii facial electromyographic (EMG) reactivity toward emotional pictures (i.e., pleasant and unpleasant) in a picture-viewing task were measured before treatment and 2 and 6weeks after treatment was started. The startle and corrugator EMG activities increase with the exposure to unpleasant cues, and served as indices for negative emotional reactivity (NER). We found that after 6weeks, drug reduced startle-related NER in the varenicline group, but not in the bupropion or placebo group. Independent of medication treatment, lower baseline NER, as measured by the corrugator EMG activity, predicted a higher likelihood of smoking abstinence 1 and 3months after quitting smoking. These findings indicate the important roles of varenicline in negative affect processing and negative emotional reactivity in the course of smoking cessation.

Is Neural Processing of Negative Stimuli Altered in Addiction Independent of Drug Effects? Findings From Drug-Naïve Youth with Internet Gaming Disorder.

Difficulties in emotion regulation are commonly reported among individuals with alcohol and drug addictions and contribute to the acquisition and maintenance of addictive behaviors. Alterations in neural processing of negative affective stimuli have further been demonstrated among individuals with addictions. However, it is unclear whether these alterations are a general feature of addictions or are a result of prolonged exposure to drugs of abuse. To test the hypothesis of altered negative affect processing independent of drug effects, this study assessed neural function among drug-naïve youth with a behavioral addiction-Internet gaming disorder (IGD). Fifty-six young adults (28 with IGD, 28 matched controls) participated in fMRI scanning during performance of a well-validated emotion regulation task. Between-group differences in neural activity during task performance were assessed using a whole-brain, mixed-effects ANOVA with correction for multiple comparisons at currently recommended thresholds (voxel-level p<0.001, pFWE<0.05). Compared to controls, youth with IGD exhibited significantly blunted neural responses within distributed subcortical and cortical regions including the striatum, insula, lateral prefrontal cortex and anterior cingulate in response to negative affective cues, as well as during emotion regulation. Independent component analysis (ICA) further identified between-group differences in engagement of a fronto-cingulo-parietal network, involving decreased engagement in IGD youth relative to controls. Study findings are largely consistent with those from prior neuroimaging studies in substance-use disorders, thus raising the possibility that neural processing of negative affect may be blunted across drug and behavioral addictions independent of acute or chronic drug effects.

Reward and loss anticipation in panic disorder: An fMRI study

Anticipatory anxiety and harm avoidance are essential features of panic disorder (PD) and may involve deficits in the reward system of the brain, in particular in the ventral striatum. While neuroimaging studies on PD have focused on fearful and negative affective stimulus processing, no investigations have directly addressed deficits in reward and loss anticipation. To determine whether the ventral striatum shows abnormal neural activity in PD patients during anticipation of loss or gain, an event-related functional magnetic resonance imaging experiment using a monetary incentive delay task was employed in 10 patients with PD and 10 healthy controls. A repeated-measures ANOVA to identify effects of group (PD vs. Control) and condition (anticipation of loss vs. gain vs. neutral outcome) revealed that patients with PD showed significantly reduced bilateral ventral striatal activation during reward anticipation but increased activity during loss anticipation. Within the patient group, the degree of activation in the ventral striatum during loss-anticipation was positively correlated with harm avoidance and negatively correlated with novelty seeking. These findings suggest that behavioural impairments in panic disorder may be related to abnormal neural processing of motivational cues.

Childhood adversity predicts reduced physiological flexibility during the processing of negative affect among adolescents with major depression histories

BackgroundAdversity during early development has been shown to have enduring negative physiological consequences. In turn, atypical physiological functioning has been associated with maladaptive processing of negative affect, including its regulation. The present study therefore explored whether exposure to adverse life events in childhood predicted maladaptive (less flexible) parasympathetic nervous system functioning during the processing of negative affect among adolescents with depression histories. MethodsAn initially clinic-referred, pediatric sample (N=189) was assessed at two time points. At Time 1, when subjects were 10.17years old (SD=1.42), on average, and were depressed, parents reported on adverse life events the offspring experienced up to that point. At Time 2, when subjects were 17.18years old (SD=1.28), and were remitted from depression, parents again reported on adverse life events in their offspring's lives for the interim period. At time 2, subjects' parasympathetic nervous system functioning (quantified as respiratory sinus arrhythmia) also was assessed at rest, during sad mood induction, and during instructed mood repair. ResultsExtent of adverse life events experienced by T1 (but not events occurring between T1 and T2) predicted less flexible RSA functioning 7years later during the processing of negative affect. Adolescents with more extensive early life adversities exhibited less vagal withdrawal following negative mood induction and tended to show less physiological recovery following mood repair. ConclusionsEarly adversities appear to be associated with less flexible physiological regulatory control during negative affect experience, when measured later in development. Stress-related autonomic dysfunction in vulnerable youths may contribute to the unfavorable clinical prognosis associated with juvenile-onset depression.

Disrupting Sleep: The Effects of Sleep Loss on Psychotic Experiences Tested in an Experimental Study With Mediation Analysis.

Our view is that insomnia may be a causal factor in the occurrence of psychotic experiences such as paranoia and hallucinations. However, the causal relationship is not established. The aim of the study was to investigate the causal role of insomnia in psychotic experiences via a sleep restriction manipulation. The study was a within-subjects crossover design that included a planned mediation analysis. Sixty-eight nonclinical volunteers underwent a sleep loss condition (restricted to 4 h sleep for 3 nights) and a control condition (standard sleep) in randomized order in 2 consecutive weeks, with a weekend washout period. Psychotic experiences (paranoia, hallucinations, grandiosity, and cognitive disorganization) and candidate mediating variables (negative affect and related processes, working memory, decision making, and perceptual processing) were assessed before and after each condition. Actigraphy verified an average sleep duration of 5 h 15 min in the sleep loss condition, vs 6 h 58 min in the control condition. After the sleep loss condition, relative to the control condition, participants reported significant increases in paranoia, hallucinations, and cognitive disorganization, with no significant changes in grandiosity. The sleep loss condition was also associated with significant increases in negative affect, negative self and other cognitions, worry, and working memory impairment. Mediation analyses indicated that changes in psychotic experiences were mediated by changes in negative affect and related processes, but not memory impairment. The overall conclusion is that insomnia has a causal role in the occurrence of certain psychotic experiences, and that a key route is via negative affect.

Neural substrates underlying the effects of oxytocin: a quantitative meta-analysis of pharmaco-imaging studies.

The hypothalamic peptide oxytocin (OT) is crucial in social adaptation and used to treat emotional and social deficits. Here, we conducted a systematic, quantitative meta-analysis of functional-MRI studies intranasally administering OT (IN-OT) to uncover neural substrates underlying the IN-OT effects and to elucidate differential IN-OT effects between healthy and clinical populations. Meta-analyses were conducted on 66 IN-OT fMRI studies, stratified by psychopathology, valence and sex. IN-OT increased bilateral amygdala, caudate head, and superior temporal activity in healthy individuals and increased dorsal anterior cingulate activity in patients. Moreover, IN-OT decreased amygdala activity in both patients and healthy individuals but did so to a greater degree in patients than healthy individuals. The OT-increased amygdala activity was only found on the negative social and affective processes, whereas the OT-decreased amygdala activity was mainly contributed by contrasts on negative-valenced processes. IN-OT increased parahippocampal activity and decreased amygdala activity during negative socio-affective processing. During positive socio-affective processes, IN-OT increased caudate head activity. This study indicates convergent neural substrates and the underlying neuropsychological mechanisms for IN-OT effects on social and affective processes. The common and different effects of IN-OT on patients and healthy individuals and the modulation of OT effects by valence have critical implications.

Meditation-induced neuroplastic changes in amygdala activity during negative affective processing

ABSTRACTRecent evidence suggests that the effects of meditation practice on affective processing and resilience have the potential to induce neuroplastic changes within the amygdala. Notably, literature speculates that meditation training may reduce amygdala activity during negative affective processing. Nonetheless, studies have thus far not verified this speculation. In this longitudinal study, participants (N = 21, 9 men) were trained in awareness-based compassion meditation (ABCM) or matched relaxation training. The effects of meditation training on amygdala activity were examined during passive viewing of affective and neutral stimuli in a non-meditative state. We found that the ABCM group exhibited significantly reduced anxiety and right amygdala activity during negative emotion processing than the relaxation group. Furthermore, ABCM participants who performed more compassion practice had stronger right amygdala activity reduction during negative emotion processing. The lower right amygdala activity after ABCM training may be associated with a general reduction in reactivity and distress. As all participants performed the emotion processing task in a non-meditative state, it appears likely that the changes in right amygdala activity are carried over from the meditation practice into the non-meditative state. These findings suggest that the distress-reducing effects of meditation practice on affective processing may transfer to ordinary states, which have important implications on stress management.

Sex differences in the development of emotion circuitry in adolescents at risk for substance abuse: a longitudinal fMRI study.

There is substantial evidence for behavioral sex differences in risk trajectories for alcohol and substance use, with internalizing factors such as negative affectivity contributing more to female risk. Because the neural development of emotion circuitry varies between males and females across adolescence, it represents a potential mechanism by which underlying neurobiology contributes to risk for substance use. Longitudinal functional magnetic resonance imaging was conducted in males and females (n = 18 each) with a family history of alcohol use disorders starting at ages 8–13 years. Participants performed an affective word task during functional magnetic resonance imaging at 1- to 2-year intervals, covering the age range of 8.5–17.6 years (3–4 scans per participant). Significant age-related sex differences were found in the right amygdala and right precentral gyrus for the negative vs neutral word condition. Males showed a significant decrease in both amygdala and precentral gyrus activation with age, whereas the response in females persisted. The subjective experience of internalizing symptomatology significantly increased with age for females but not for males. Taken together, these results reveal sex differences in negative affect processing in at-risk adolescents, and offer longitudinal neural evidence for female substance use risk through internalizing pathways.

Brain structural changes in patients with chronic myofascial pain.

Myofascial trigger points (MTrPs) are a highly prevalent source of musculoskeletal pain. Prolonged ongoing nociceptive input from MTrPs may lead to maladaptive changes in the central nervous system. It remains, however, unknown whether pain from MTrPs is associated with brain atrophy. In addition, stress, which may contribute to the formation of MTrPs, is also known to affect brain structures. Here, we address whether structural brain changes occur in patients with chronic pain originating from MTrPs and whether such changes are related to pain or stress. Voxel-based morphometry was used to compare grey-matter (GM) volumes in 21 chronic pain patients, with MTrPs in the bilateral upper trapezius muscles, with 21 healthy controls. Hyperalgesia was assessed by pressure pain thresholds, and stress was assessed by cortisol levels and anxiety questionnaires. Patients exhibited normal stress levels but lowered pain thresholds. GM atrophy was found in dorsal and ventral prefrontal regions in patients. The GM density of the right dorsolateral prefrontal cortex correlated with pain thresholds in patients, i.e. the more atrophy, the lower pain threshold. GM atrophy was also found in the anterior hippocampus, but the atrophy was neither related to pain nor stress. Patients with chronic myofascial pain exhibit GM atrophy in regions involved in top-down pain modulation and in processing of negative affect. The relationship between the dorsolateral prefrontal cortex and pain thresholds suggests the presence of pain disinhibition. No evidence was found for the involvement of stress. It remains unclear whether the observed atrophy contributes to the development of the chronic pain state or is caused by the ongoing nociceptive input. Chronic myofascial pain, caused by myofascial trigger points, is associated with localized brain atrophy in areas involved in pain processing and modulation, among others. These findings extend previous knowledge about peripheral and spinal changes to the supraspinal level.

Loneliness in late-life depression: structural and functional connectivity during affective processing.

Late-life depression (LLD) in the elderly was reported to present with emotion dysregulation accompanied by high perceived loneliness. Previous research has suggested that LLD is a disorder of connectivity and is associated with aberrant network properties. On the other hand, perceived loneliness is found to adversely affect the brain, but little is known about its neurobiological basis in LLD. The current study investigated the relationships between the structural connectivity, functional connectivity during affective processing, and perceived loneliness in LLD. The current study included 54 participants aged >60 years of whom 31 were diagnosed with LLD. Diffusion tensor imaging (DTI) data and task-based functional magnetic resonance imaging (fMRI) data of an affective processing task were collected. Network-based statistics and graph theory techniques were applied, and the participants' perceived loneliness and depression level were measured. The affective processing task included viewing affective stimuli. Structurally, a loneliness-related sub-network was identified across all subjects. Functionally, perceived loneliness was related to connectivity differently in LLD than that in controls when they were processing negative stimuli, with aberrant networking in subcortical area. Perceived loneliness was identified to have a unique role in relation to the negative affective processing in LLD at the functional brain connectional and network levels. The findings increas our understanding of LLD and provide initial evidence of the neurobiological mechanisms of loneliness in LLD. Loneliness might be a potential intervention target in depressive patients.

To branch out or stay focused? Affective shifts differentially predict organizational citizenship behavior and task performance.

We draw from personality systems interaction (PSI) theory (Kuhl, 2000) and regulatory focus theory (Higgins, 1997) to examine how dynamic positive and negative affective processes interact to predict both task and contextual performance. Using a twice-daily diary design over the course of a 3-week period, results from multilevel regression analysis revealed that distinct patterns of change in positive and negative affect optimally predicted contextual and task performance among a sample of 71 employees at a medium-sized technology company. Specifically, within persons, increases (upshifts) in positive affect over the course of a workday better predicted the subsequent day's organizational citizenship behavior (OCB) when such increases were coupled with decreases (downshifts) in negative affect. The optimal pattern of change in positive and negative affect differed, however, in predicting task performance. That is, upshifts in positive affect over the course of the workday better predicted the subsequent day's task performance when such upshifts were accompanied by upshifts in negative affect. The contribution of our findings to PSI theory and the broader affective and motivation regulation literatures, along with practical implications, are discussed. (PsycINFO Database Record

Brain networks sub-serving self-referential processing in depression

IntroductionPersistent pondering over negative self-related thoughts is a central feature of depressive psychopathology.ObjectivesIn the present study, we sought to investigate the neural correlates of abnormal negative self-referential processing (SRP) in patients with major depressive disorder (MDD) and its impact on subsequent cognitive control-related neuronal activation.AimsWe hypothesized aberrant activation dynamics during the period of negative and neutral SRP in the rostral anterior cingulate cortex (rACC) and in the amygdala in patients with MDD. We assumed abnormal activation in the fronto-cingulate network during Stroop task execution.MethodsNineteen depressed patients and 20 healthy controls participated in the study. Using an event-related fMRI design, negative, positive and neutral self-referential statements were displayed for 6.5s and followed by incongruent or congruent Stroop conditions.ResultsIn contrast to controls, patients did not exhibit valence-dependent rACC activation differences during SRP. A novel finding was the significant activation of the amygdala and the reward-processing network during presentation of neutral self-referential stimuli relative to baseline and to affective stimuli in patients. The fMRI analysis of the Stroop task revealed a reduced BOLD activation in the right frontoparietal network of patients in the incongruent condition after negative SRP only.ConclusionsThus, the inflexible activation in the rACC may correspond to the inability of depressed patients to shift their attention away from negative self-related stimuli. The accompanying negative affect and task-irrelevant emotional processing may compete for neuronal resources with cognitive control processes and lead thereby to deficient cognitive performance associated with decreased frontoparietal activation.Disclosure of interestThe authors have not supplied their declaration of competing interest.
