RESUMO

BACKGROUND: Affect states are posited to play a pivotal role in addiction-related processes, including tobacco lapse (i.e., smoking during a quit attempt), and distinct affective states (e.g., joy vs. happiness) may differentially influence lapse likelihood. However, few studies have examined the influence of distinct affective states on tobacco lapse. PURPOSE: This study examines the influence of 23 distinct affect states on tobacco lapse among a sample of tobacco users attempting to quit. METHODS: Participants were 220 adults who identified as African American (50% female, ages 18-74). Ecological momentary assessment was used to assess affect and lapse in real-time. Between and within-person associations testing links between distinct affect states and lapse were examined with multilevel modeling for binary outcomes. RESULTS: After adjusting for previous time's lapse and for all other positive or negative affect items, results suggested that at the between-person level, joy was associated with lower odds of lapse, and at the within-person level, attentiveness was associated with lower odds of lapse. Results also suggested that at the between-person level, guilt and nervous were associated with higher odds of lapse, and at the within-person level, shame was associated with higher odds of lapse. CONCLUSIONS: The present study uses real-time, real-world data to demonstrate the role of distinct positive and negative affects on momentary tobacco lapse. This work helps elucidate specific affective experiences that facilitate or hinder the ability to abstain from tobacco use during a quit attempt.

RESUMO

Savoring is a positive emotion up-regulation technique that can increase electrocortical and self-reported valence and arousal to positive and neutral pictures, with effects persisting to increase response to the same stimuli when encountered later. Outside of the lab, emotion regulation techniques that persist to affect not just encounters with the same stimuli but also encounters with similar, but previously unencountered stimuli should save individuals time and effort. Here, we used event-related potentials and picture ratings to test whether savoring would generalize to similar, but previously unseen positive pictures. To this end, 89 participants (56 female; M age = 18.96 years, SD = 1.87) were asked to savor positive pictures from one category (e.g., happy people) and to view positive pictures from another category (e.g., cute animals), as well as to view neutral pictures (e.g., plants). In a subsequent passive picture viewing task, participants viewed novel pictures from all three categories (i.e., happy people, cute animals, plants). In the first task, savoring was effective for pictures of animals throughout picture presentation, but only for pictures of people during the later part of picture presentation. In the second task, savoring generalized to novel pictures of animals, though this was only evident in the early portion of picture processing (and for self-reported ratings). Therefore, savoring holds promise as a useful technique for increasing positive emotion in everyday life, though more work is needed to understand whether effects may vary depending on different types of picture content.

RESUMO

Respiratory sinus arrhythmia (RSA), a marker of self-regulation, has been linked to developmental outcomes in young children. Although positive emotions may have the potential to facilitate physiological self-regulation, and enhanced self-regulation could underlie the development of positive emotions in early childhood, the relation between positive emotions and physiological self-regulation in infancy has been relatively overlooked. The current study examined the bidirectional associations among maternal positive emotion, infant positive emotionality, and infant resting RSA across the first 18 months of life. We used data from the Longitudinal Attention and Temperament Study (LanTs; N = 309 in the current analysis) to test the within- and between-person relations of study variables over time using a random-intercepts cross-lagged panel model. We found that infants with higher overall levels of positive emotionality also displayed greater resting RSA, and their mothers exhibited higher levels of positive emotion. However, there were negative cross-lagged associations within-person; higher than average infant positive emotionality predicted lower levels of infant resting RSA at the subsequent timepoint during early infancy, whereas higher than average infant RSA subsequently predicted decreased levels of infant positive emotionality later in infancy. Results highlight the importance of considering transactional relations between positive emotion and physiological self-regulation in infancy.

RESUMO

INTRODUCTION: Individuals with greater affect variability (i.e., moment-to-moment fluctuations possibly reflecting emotional dysregulation) are at risk for greater systemic inflammation, which is associated with cardiovascular disease. Some evidence suggests that affect variability is linked with poorer health indicators only among those with higher average levels of affect, particularly for positive affect (PA), and that associations may be non-linear. The present study sought to examine whether links between both PA and negative affect (NA) variability and inflammation are moderated by average level of affect. METHODS: Participants (N = 300, 50 % female, ages 21-70, 60 % non-Hispanic White, 19 % Hispanic, 15 % non-Hispanic Black) completed a lab assessment and provided a blood sample to measure systemic inflammation (i.e., TNF-α, IL-6, CRP). Affect was collected via a two-day ecological momentary assessment protocol where reports were collected about every 45-min during waking hours. Momentary affect ratings were averaged across both days (i.e., iM), separately for PA and NA, for each participant. Affect variability was calculated as the person-specific SD (i.e., iSD) of affect reports, separately for PA and NA. Linear and quadratic interactions were tested. Models included covariates for sex, race, and body mass index. RESULTS: There were significant interactions between NA iM and NA iSD predicting TNF-α (b = 6.54; p < 0.05) and between PA iM and PA iSD predicting IL-6 (b = 0.45; p < 0.05). Specifically, the association between these affect variability indicators and inflammatory markers were suggestive of a positive association among those with higher average affect but a negative association among those with lower average affect. There was no evidence of non-linear associations between affect and inflammation. DISCUSSION: Incorporating interactive effects between affect variability and average affect may be an important consideration in understanding affective-inflammatory associations.

RESUMO

OBJECTIVE: Previous work has outlined cognitive beliefs about exercise in general, but very little is known about momentary cognitions while engaging in pathological exercise. The primary aim of this study was to explore thought content during exercise and to test whether these thoughts predicted later engagement in eating disorder behaviors. We also tested associations between thoughts and specific exercise activity. METHOD: We monitored 31 women with clinically significant eating psychopathology for 3 weeks via ecological momentary assessment as they reported on their exercise and eating disorder behaviors, and thoughts about shape, weight, or calories during exercise. Thoughts were self-reported upon cessation of each exercise session. RESULTS: Thinking about weight loss during exercise predicted later engagement in body-checking behaviors. Weight-bearing exercise was associated with a decreased likelihood of thinking about calories but an increased likelihood of thinking about shape during exercise. DISCUSSION: These findings show that shape and weight thoughts are present during exercise and that their influence on eating disorder behaviors may exist on a much briefer time scale (i.e., within a day) than previous studies show. Clinically, future studies may seek to test interventions aimed at changing or restructuring cognitions during exercise to help shape adaptive exercise behavior during and after treatment. PUBLIC SIGNIFICANCE: This is the first study measuring thoughts during pathological exercise in real-time among those with eating disorder psychopathology. The results show that thinking about weight loss during exercise might increase the likelihood of engaging in body-checking behaviors. Findings will inform the development of treatment approaches to help those in recovery from eating disorders re-engage with exercise.

RESUMO

OBJECTIVES: Research has demonstrated links between autobiographical memory retrieval and hazardous substance use. However, limited work has examined relations between positive autobiographical memories and hazardous substance use, as well as moderating factors influencing these relations. Thus, we examined the potential moderating roles of negative and positive emotion dysregulation in the relations between count of retrieved positive memories and hazardous substance use (alcohol and drug use separately). METHODS: Participants were 333 trauma-exposed students (Mage = 21.05; 85.9% women) who completed self-report measures assessing positive memory count, hazardous alcohol and drug use, negative emotion dysregulation, and positive emotion dysregulation. RESULTS: Positive emotion dysregulation significantly moderated the association between positive memory count and hazardous alcohol use (b = 0.04, 95% confidence interval [CI] [0.01, 0.06], p = 0.019), as well as the association between positive memory count and hazardous drug use (b = 0.02, 95% CI [0.01, 0.03], p = 0.002). Individuals with more positive emotion dysregulation had stronger associations between increases in positive memory count and increased hazardous substance use. CONCLUSION: Findings indicate that trauma-exposed individuals who retrieve more positive memories and experience difficulties regulating positive emotions report greater hazardous substance use. Positive emotion dysregulation may be an important target for memory-based interventions among trauma-exposed individuals who report hazardous substance use.

RESUMO

Although psychotherapy research has traditionally focused on decrease in distress, emotion research suggests the important role of positive emotional experience in healing and growing. Objective: The present study investigates the relationship between positive emotional experiences and working alliance. Method: We chose to investigate this relationship in accelerated experiential dynamic psychotherapy (AEDP), taking advantage of the modality's focus on both negative and positive emotional experiences. Fifty-eight clients receiving 16-sessions individual AEDP reported on their post-session levels of working alliance and positive emotions (enlivenment affect, positive relational affect, and peacefulness). The alliance-emotion relationship for each emotional categories was tested with separate disaggregated cross-lagged panel models. Results: Across the three categories, higher positive emotions at the end of the previous session were associated with higher working alliance at the end of the next session. On the other hand, working alliance did not contribute to any of the positive emotions in the next time point. Furthermore, the three emotion categories showed different patterns of development. Conclusion: The findings suggest that fostering positive emotions may be a promising venue to enhance working alliance. Furthermore, differentiating specific positive emotions is likely important both for research and practice.

RESUMO

As the science of wellbeing has grown, universities have adopted the challenge of prioritizing the wellbeing of students. Positive psychology interventions (PPIs), activities designed to increase the frequency of positive emotions and experiences, which help to facilitate the use of actions and thoughts that lead to human flourishing, are being increasingly used worldwide. Known to boost wellbeing and a number of other variables, it nonetheless remains unknown whether their use can influence other variables in non-Western cultures. In this study, we determined the impact of PPIs on a variety of wellbeing outcomes. The 6-week PPI program was conducted in the United Arab Emirates on Emirati university students (n = 120) who reported more positive emotion and overall balance of feelings that favored positivity over time relative to a control group. Yet, there was no effect found on negative emotions, life satisfaction, perceived stress, fear of happiness, locus of control, or somatic symptoms, and no effect on levels of collectivism or individualism. Our findings nonetheless support the use of PPIs in higher education as they show an increase in the experience of positive emotion, with this in itself bringing positive life outcomes, and no negative impact on culture. Our findings serve to build a foundation for understanding for whom PPIs work best - and least - around the world.

RESUMO

BACKGROUND: Cataplexy is a loss of muscle tone that can lead to postural collapse, disturbing the daily life of narcolepsy patients; it is often triggered by positive emotions such as laughter in human patients. Narcolepsy model mice also show cataplexy, and its incidence increases in response to positive emotion-inducing stimuli such as chocolate and female courtship. Although such observation indicates a positive emotion-related nature of cataplexy in narcolepsy mice, they also show cataplexy without any apparent triggering stimulus ~ (spontaneous cataplexy). Therefore, we hypothesized that some spontaneous cataplexy in narcoleptic mice might indicate the remembering of happy moments. RESULTS: To test our hypothesis, we did a conditioned place preference test on orexin/hypocretin neuron-ablated (ORX-AB) mice, one of the animal models of human narcolepsy, and counted the number of cataplexy-like behaviors. ORX-AB mice successfully remembered the chocolate-associated chamber, and the number of cataplexy-like behaviors significantly increased in the chocolate-associated chamber but not in the control chamber. In addition, ORX-AB mice remembered the aversive odor-associated chamber and avoided entering without affecting the number of cataplexy-like behaviors. Finally, similar activation of the nucleus accumbens, a positive emotion-related nucleus, was observed during both spontaneous and chocolate-induced cataplexy behaviors. CONCLUSIONS: These results support our hypothesis and will promote the usefulness of a narcolepsy mice model in emotion research and serve as a basis for a better understanding of cataplexy in narcolepsy patients.

RESUMO

Poor sleep patterns have been strongly linked to disrupted emotional experiences. Emotion regulation, defined as the capacity to manage one's own emotional responses, comprises strategies to increase, maintain, or decrease the intensity, duration, and trajectory of positive and negative emotions. Poor sleep has been identified as a risk factor for emotional dysregulation, but most of the focus has been on negative emotion regulation. We therefore asked whether natural variations in sleep are associated with the experience and regulation of both positive and negative emotion. Young adults, aged between 18-24 years (N = 101), completed 7 days of ecological momentary assessments using a smartphone application. Duration and quality of the previous night's sleep was reported each morning. Levels of positive and negative emotions, and strategies used to regulate emotions, were measured at pseudorandom timepoints four times a day. Multilevel modelling indicated that higher self-reported sleep quality was significantly associated with increased intensity and duration of positive emotion, and decreased intensity of negative emotion. There were no statistically significant associations between sleep duration and emotion intensity or duration. Sleep quality, and not sleep duration, was also associated with the reported use of positive emotion regulation strategies. For negative emotion regulation strategy use, we found no associations with sleep quality or duration. Naturally occurring fluctuations in daily sleep quality may be important for the experience and regulation of positive emotion in young adults. These findings emphasise the need to examine both positive and negative emotion, and emotion regulation to understand the links between sleep and mood.

RESUMO

Previous longitudinal evidence suggested that sleep disturbance (i.e., difficulties in sleep onset and sleep maintenance) may be longitudinally associated with systemic inflammation, which is involved in the pathophysiology of mental and somatic illness. The mechanisms underlying this association, however, remain largely unexplored. In the context of health psychology, a substantial body of literature showed that positive affect may have a favourable impact on immune and inflammatory response and buffer the proinflammatory effects of stress. Therefore, the aim of this study was to assess whether subjective sleep disturbance is longitudinally associated with serum high sensitivity C-reactive protein (hs-CRP), a marker of systemic inflammation, and whether this association is mediated by a decrease in positive affect. The data of 1894 participants aged 64.11 ± 8.02 years from the English Longitudinal Study of Ageing (ELSA) across three waves of data collection were analysed. Self-reported sleep disturbance was assessed in 2008-2009, (wave 4), positive affect was assessed in 2010-2011 (wave 5), and hs-CRP was assessed in 2012-2013 (wave 6). Path analysis adjusted for health-related variables including depressive symptoms, cardiovascular disease, BMI, smoking, alcohol consume, and drug intake showed a significant direct effect of sleep disturbance to positive affect; positive affect directly predicted hs-CRP. Lastly, an indirect effect between sleep disturbance to hs-CRP through the mediating role of positive affect emerged. The findings suggest that sleep onset and sleep maintenance difficulties may be associated with inflammation through the mediation of low positive affect. The clinical significance of the findings should be further explored.

RESUMO

In the process of interacting with people and objects, humans assign affective valence. By using an association-transfer paradigm, the current study investigated whether the emotion associated with a stimulus would have an impact on cognitive control outcomes. During the association phase of two experiments reported here, participants identified the emotion expressed by an actor's face as either positive (i.e., smiling) or negative (i.e., frowning). Half of the actors expressed positive emotions (MP) on 80% of trials, while the other half expressed negative emotions (MN) on 80% of trials. We tested the cognitive effect of these associations in two experiments. In the transfer phase of Experiment 1, the same actors from the association phase were shown with neutral expression during a gender Stroop task, requiring participants to identify the gender of the face while ignoring a gender word (congruent or incongruent) that was imposed upon the face. The Stroop effect was significant for the MN faces, but the effect disappeared for the MP faces. In the transfer phase of Experiment 2, the emotionless faces were presented in a task-switching paradigm, in which participants identified the age (i.e., old or young) or the gender depending on the task cue. The task switch cost was smaller (though significant) for the MP faces than for the MN faces. These results suggest that, relative to social stimuli associated with negative expressions, social stimuli associated with positive expressions can promote better cognitive control and inhibit distractor interference in goal-oriented behavior.

RESUMO

AIMS AND OBJECTIVES: To evaluate the effectiveness of horticultural therapy on cognitive function, agitation, positive emotion and engagement in people with dementia. BACKGROUND: The number of people with dementia is increasing rapidly, and nonpharmacological interventions such as horticultural therapy have been recommended as the first choice for these patients. Horticultural therapy involves participatory and ornamental horticultural therapy. Many original studies have examined the effectiveness of horticultural therapy in the last two decades. However, these studies vary in types of interventions, outcomes and measurement. DESIGN: A quantitative systematic review and meta-analysis. METHODS: This systematic review was conducted under PRISMA guidelines. Randomised controlled trials (RCTs) and quasi-experimental studies involving horticultural therapy for people with dementia were included. Risk of bias was assessed by the Cochrane's and Joanna Briggs Institute's tool. Reference lists and a relevant journal were searched. Meta-analyses were conducted using RevMan 5.3. PubMed, CINAHL, Embase, BIOSIS Previews, Web of Science Core Collection, China National Knowledge Infrastructure, Wanfang, SinoMed, Cochrane Library and ProQuest Health & Medical Complete were searched. Studies from database inception to 1 July 2019 were included. RESULTS: This systematic review included 14 studies (4 RCTs and 10 quasi-experimental studies) involving 411 people with dementia. The results of meta-analyses indicated that significant differences were found in the effectiveness of participatory horticultural therapy on total score of cognitive function, agitation, positive emotion and engagement, but not in the effectiveness of ornamental horticultural activities on agitation and positive emotion. CONCLUSIONS: The existing evidence supports the effectiveness of participatory horticultural therapy on cognitive function, agitation, positive emotion and engagement. Future high-quality original studies are needed to draw more robust conclusions. RELEVANCE TO CLINICAL PRACTICE: The results support the use of participatory horticultural therapy for improving cognitive function, agitation, positive emotion and engagement of people with dementia.

RESUMO

Today, it is possible to investigate the biological paths and mechanisms that link mental life to biological life. Emotions, feelings, desires, and cognitions influence biological systems. In recent decades, psychoneuroendocrinoimmunology research has highlighted the routes linking the psyche-brain-immune systems. Recently, epigenetics research has shown the molecular mechanisms by which stress and mental states modulate the information contained in the genome. This research shapes a new paradigm considering the human being as a whole, integrating biology and psychology. This will allow us to progress towards personalized precision medicine, deeply changing medical and psychological sciences and clinical practice. In this paper, we recognize leading research on both bidirectional relations between the psyche-brain-immunity and molecular consequences of psychological and mental states.

RESUMO

This study explores the relationship between adolescents' perceptions of epidemic risk and their emotions through three follow-up surveys during the early stages of the COVID-19 pandemic on February 11th (T1), 18th (T2), and 25th (T3), 2020. Three hundred and four adolescents in different academic stages (junior high middle school, senior high middle school, and university) participated in the online survey, and cross-lag analysis was used to examine the causal relationship between epidemic risk perceptions and positive and negative emotions. The results found that the individual's positive emotions were significantly higher than the negative emotions in T1, T2 and T3. Cross-lag analysis found that for positive emotions, T2 positive emotions could negatively predict T3 epidemic risk perceptions, and T2 epidemic risk perceptions could negatively predict the individual's T3 positive emotions. For negative emotions, risk perceptions at T1 could positively predict negative emotions at T2, and at the same time, negative emotions at T1 could also positively predict epidemic risk perceptions at T2. This indicates that during the early stages of the COVID-19 pandemic, there was a causal relationship between the perceptions of epidemic risk and the emotions of adolescents, and this relationship had high stability among groups of different genders and academic stages.

RESUMO

Human adult laughter is characterized by vocal bursts produced predominantly during exhalation, yet apes laugh while exhaling and inhaling. The current study investigated our hypothesis that laughter of human infants changes from laughter similar to that of apes to increasingly resemble that of human adults over early development. We further hypothesized that the more laughter is produced on the exhale, the more positively it is perceived. To test these predictions, novice (n = 102) and expert (phonetician, n = 15) listeners judged the extent to which human infant laughter (n = 44) was produced during inhalation or exhalation, and the extent to which they found the laughs pleasant and contagious. Support was found for both hypotheses, which were further confirmed in two pre-registered replication studies. Likely through social learning and the anatomical development of the vocal production system, infants' initial ape-like laughter transforms into laughter similar to that of adult humans over the course of ontogeny.

RESUMO

Previous research has suggested that sharing autobiographical memories in a coherent manner has a beneficial impact on consequent social reactions of listeners. In this experimental study, we were able to replicate earlier findings by demonstrating that listeners (N = 107) showed significantly more willingness to interact with, more social support towards, and a more positive attitude towards coherent than incoherent narrators. Remarkably, these beneficial effects of coherence were observed only for narratives about positive memories. Results are explained in the light of the relevance of positive memories for the social bonding function of autobiographical memory. Furthermore, earlier work was extended and refined by investigating effects of the individual constituting dimensions of coherence (context, chronology, theme) on social responses. In line with our predictions, the dimensions of chronology and theme were most important in impacting social responses of listeners. Possibly a reduction of the attraction effect due to increased effortful processing and reduced credibility due to insufficient emotional elaboration might explain these results respectively. Furthermore, social responses were worse when narratives were incoherent with regard to more than one dimension, in line with the expected additive effect. Overall, fully incoherent narratives, which had had low scores on context, chronology, and theme, had the most adverse effect on listeners' social responses. This study adds significantly to the domain of memory and cognition by showing how cognitive psychological research would benefit from extending a merely intrapersonal perspective to include an interpersonal perspective that considers social implications of memory and cognition as well.

RESUMO

BACKGROUND: Studies on age differences in emotional states during the COVID-19 pandemic showed that older adults experienced greater emotional wellbeing compared to younger adults. We hypothesized these age differences to be related to the perception of closeness to family/friends or the engagement in daily activities during the pandemic. AIM: To investigate age differences in positive and negative emotional experiences and whether the perception of closeness to family/friends and the engagement in daily activities during pandemic explained such age-related differences. METHODS: Through a cross-sectional study, 1,457 adults aged 18-87 years old completed an online survey assessing positive and negative emotional experiences, the perception of more closeness to family/friends, and daily activities that participants started/re-started during the pandemic. RESULTS: Increasing age was associated with more positive and less negative emotional experiences. Age differences in positive emotional experience were explained by the perception of more closeness to friends and not by the engagement in daily activities. For negative emotional experience age, differences remained significant even after accounting for the perception of closeness to family/friends and engagements in daily activities. DISCUSSION: Older adults' greater overall level of positive emotional experience was explained by their greater perception of more closeness to friends. We speculate that social closeness provides a coping mechanism to increase emotional wellbeing employed especially in older adults. CONCLUSION: Our findings reinforce the link between perceived social closeness and emotional wellbeing especially in older adults. To cope with stressful situation, it is important to encourage older adults to increase the closeness to their social network.

RESUMO

Mania, the core feature of bipolar disorder, is associated with heightened and positive emotion responding. Yet, little is known about the underlying cognitive processes that may contribute to heightened positive emotionality observed. Additionally, while previous research has investigated positive emotion biases in non-clinical samples, few if any, account for subthreshold clinical symptoms or traits, which have reliably assessed psychopathological risk. The present study compared continuous scores on a widely used self-report measure of hypomania proneness (HPS-48) with a dot-probe task to investigate attentional biases for happy, angry, fearful, and neutral faces among 66 college student participants. Results suggested that hypomania proneness was positively associated with attentional bias towards happy, but not angry or fearful faces. Results remained robust when controlling for positive affect and did not appear to be affected by negative affect or current symptoms of depression, anxiety, and stress. Findings provide insight into potential behavioural markers that co-occur with heightened positive emotional responding and hypomania in emerging adults.

Although affect labelling has been widely reported to decrease negative emotions, it is less clear whether affect labelling also decreases positive emotions. In four studies, we explored how affect labelling (choosing the emotion that best corresponds with the image), content labelling (choosing the word that best corresponds with the content of the image), and simply viewing images influence positive and negative emotions. Labelling positive emotions led participants to report higher positive emotional intensity than did content labelling or just viewing the image (Study 1, N = 49), and this effect persisted regardless of whether they labelled emotions during or after the image (Study 2, N = 116), rated the intensity or positivity of their emotions (Study 3, N = 120), or rated their emotions after a delay or no delay (Study 4, N = 120). Surprisingly, we did not replicate the previous findings on affect labelling and negative emotion, instead showing that content labelling of negative emotional images tended to be the most consistent predictor of decreased negative emotions. Our results challenge the formulation that affect labelling leads to the automatic downregulation of emotions and instead suggest that it might be an effective mechanism in the upregulation of positive emotions.
