RESUMO
Do larger incomes make people happier? Two authors of the present paper have published contradictory answers. Using dichotomous questions about the preceding day, [Kahneman and Deaton, Proc. Natl. Acad. Sci. U.S.A. 107, 16489-16493 (2010)] reported a flattening pattern: happiness increased steadily with log(income) up to a threshold and then plateaued. Using experience sampling with a continuous scale, [Killingsworth, Proc. Natl. Acad. Sci. U.S.A. 118, e2016976118 (2021)] reported a linear-log pattern in which average happiness rose consistently with log(income). We engaged in an adversarial collaboration to search for a coherent interpretation of both studies. A reanalysis of Killingsworth's experienced sampling data confirmed the flattening pattern only for the least happy people. Happiness increases steadily with log(income) among happier people, and even accelerates in the happiest group. Complementary nonlinearities contribute to the overall linear-log relationship. We then explain why Kahneman and Deaton overstated the flattening pattern and why Killingsworth failed to find it. We suggest that Kahneman and Deaton might have reached the correct conclusion if they had described their results in terms of unhappiness rather than happiness; their measures could not discriminate among degrees of happiness because of a ceiling effect. The authors of both studies failed to anticipate that increased income is associated with systematic changes in the shape of the happiness distribution. The mislabeling of the dependent variable and the incorrect assumption of homogeneity were consequences of practices that are standard in social science but should be questioned more often. We flag the benefits of adversarial collaboration.

The ability to accurately identify and interpret others' emotions is critical for social and emotional functioning during adolescence. Indeed, previous research has identified that laboratory-based indices of facial emotion recognition and engagement with emotional faces predict adolescent mood states. Whether socioemotional information processing relates to real-world affective dynamics using an ecologically sensitive approach, however, has rarely been assessed. In the present study, adolescents (N = 62; ages 13-18) completed a Facial Recognition Task, including happy, angry, and sad stimuli, while EEG data were acquired. Participants also provided ecological momentary assessment (EMA) data probing their current level of happiness, anger, and sadness for 1-week, resulting in indices of emotion (mean-level, inertia, instability). Analyses focused on relations between (1) accuracy for and (2) prolonged engagement with (LPP) emotional faces and EMA-reported emotions. Greater prolonged engagement with happy faces was related to less resistance to changes in happiness (i.e., less happiness inertia), whereas greater prolonged engagement with angry faces associated with more resistance to changes in anger (i.e., greater anger inertia). Results suggest that socioemotional processes captured by laboratory measures have real-world implications for adolescent affective states and highlight potentially actionable targets for novel treatment approaches (e.g., just-in-time interventions). Future studies should continue to assess relations among socioemotional informational processes and dynamic fluctuations in adolescent affective states.

Facial emotion recognition (FER), including sadness, is altered in bipolar disorder (BD). However, the relationship between this impairment and the brain structure in BD is relatively unexplored. Furthermore, its association with clinical variables and with the subtypes of BD remains to be clarified. Twenty euthymic patients with BD type I (BD-I), 28 BD type II (BD-II), and 45 healthy controls completed a FER test and a 3D-T1-weighted magnetic resonance imaging. Gray matter volume (GMV) of the cortico-limbic regions implicated in emotional processing was estimated and their relationship with FER performance was investigated using network analysis. Patients with BD-I had worse total and sadness-related FER performance relative to the other groups. Total FER performance was significantly negatively associated with illness duration and positively associated with global functioning in patients with BD-I. Sadness-related FER performance was also significantly negatively associated with the number of previous manic episodes. Network analysis showed a reduced association of the GMV of the frontal-insular-occipital areas in patients with BD-I, with a greater edge strength between sadness-related FER performance and amygdala GMV relative to controls. Our results suggest that FER performance, particularly for facial sadness, may be distinctively impaired in patients with BD-I. The pattern of reduced interrelationship in the frontal-insular-occipital regions and a stronger positive relationship between facial sadness recognition and the amygdala GMV in BD may reflect altered cortical modulation of limbic structures that ultimately predisposes to emotional dysregulation. Future longitudinal studies investigating the effect of mood state on FER performance in BD are warranted.

INTRODUCTION: Recent technology has enabled researchers to collect ecological momentary assessments (EMA) to examine within-person correlates of suicidal thoughts. Prior studies examined generalized temporal dynamics of emotions and suicidal thinking over brief periods, but it is not yet known how variable these processes are across people. METHOD: We use data EMA data delivered over two weeks with youth/young adults (N = 60) who reported past year self-injurious thoughts/behaviors. We used group iterative multiple model estimation (GIMME) to model group- and person-specific associations of negative emotions (i.e., fear, sadness, shame, guilt, and anger) and suicidal thoughts. RESULTS: 29 participants (48.33%) reported at least one instance of a suicidal thought and were included in GIMME models. In group level models, we consistently observed autoregressive effects for suicidal thoughts (e.g., earlier thoughts predicting later thoughts), although the magnitude and direction of this link varied from person-to-person. Among emotions, sadness was most frequently associated with contemporaneous suicidal thoughts, but this was evident for less than half of the sample, while other emotional correlates of suicidal thoughts broadly differed across people. No emotion variable was linked to future suicidal thoughts in >14% of the sample, CONCLUSIONS: Emotion-based correlates of suicidal thoughts are heterogeneous across people. Better understanding of the individual-level pathways maintaining suicidal thoughts/behaviors may lead to more effective, personalized interventions.

People's emotional states are influenced not just by events occurring in the present but also by how events have unfolded in the past and how they are likely to unfold in the future. To what extent do young children understand the ways in which past events can affect current emotions even if they are no longer ongoing? In the current study, we explored children's ability to understand how others feel at the cessation of events-as events change from being present to being past. We asked 97 4- to 6-year-olds (40.2% female) and 35 adults (54.3% female) to judge how characters felt once particular types of events had ended relative to how they felt during these events. We found that from age 4, children judged (as adults do) that the character would feel positive at the cessation of negative events-what we refer to as temporal relief. This understanding of relief occurs earlier than has been shown in previous research. However, children were less likely than adults to judge others as feeling sad at the cessation of positive events-what we refer to as temporal disappointment. Overall, our findings suggest that children not only understand that the cessation of events can affect others' emotions but also recognize that people feel differently following the cessation of positive, negative, and neutral events.

Responding empathically when causing peers' emotions is critical to children's interpersonal functioning, yet there are surprising gaps in the literature. Previous research has focused on empathy when witnessing others' emotions instead of causing others' emotions, on negative emotions instead of positive emotions, and on behavioral correlates instead of neural correlates. In this study, children (N = 38; Mage = 9.28 years; 50% female) completed a functional magnetic resonance imaging block design task in which they played a rigged game where they won and lost coins for themselves or peers and viewed their peers' happiness and sadness. We used a region of interest approach to test whether activity in brain regions associated with positive and negative empathy in adults showed significantly greater activity in each condition (i.e., when children won and lost tokens for themselves and peers) compared with a fixation baseline. We predicted that experiencing self-conscious emotions, such as pride and guilt, would heighten the experience of empathy. Activity in the amygdala, which is associated with visceral arousal, and in the anterior insula and dorsal anterior cingulate cortex, which are associated with integrated arousal, increased significantly when winning and losing for oneself and peers and observing their resulting happy and sad facial expressions. Activity did not differ when playing for oneself versus peers, indicating that self-conscious emotions do not heighten empathy and instead support similar neural processes underlying firsthand and secondhand (empathic) emotions. These findings support that empathy during middle childhood involves the same brain regions as empathy during adulthood and that children experience firsthand and secondhand positive and negative emotions in similar ways.

Experimental mood induction procedures are commonly used in studies of children's emotions, although research on their effectiveness is lacking. Studies that support their effectiveness report sample-level changes in self-reported affect from pre- to post-induction, and a subset of children who do not self-report expected changes in affect (i.e., "nonresponders"). Given children's limited abilities to self-report their emotions, it is critical to know whether these paradigms also shift physiological and social-cognitive indices of emotion. We hypothesized increases in physiological reactivity and accuracy for discerning facial expressions of negative emotions from pre- to post-induction and smaller increases for nonresponders, Children (N = 80; 7- to 12-year-olds) completed a facial emotion recognition task and had an electrocardiogram recorded to index high-frequency heart rate variability (HF-HRV) before and after a mood induction procedure. The mood induction involved watching a 3-min sad film clip while attending to their feelings. In the sample overall, from pre- to post-mood induction, children self-reported significantly sadder affect, displayed significant increases in HF-HRV, and displayed significant increases in accuracy of recognizing facial emotion expressions congruent with the mood induced. One quarter (25%) of the sample did not self-report expected increases in sad affect. Contrary to expectations, responders and nonresponders did not differ in mood-induced changes in physiological reactivity or emotion recognition accuracy. These findings support that mood inductions are efficacious in shifting not only children's self-reported affect but also underlying physiological and social-cognitive processes. Furthermore, they are an effective methodology for research questions related to underlying processes even in self-reported nonresponders.

OBJECTIVES: The use of social media during bedtime has increased in the past years among adolescents, contributing to disturbed sleep quality, which could potentially be related to emotional problems. This study aimed to analyze the mediation effects of sleep parameters on the relationship between NightTime Texting (NTT) on social media and adolescent sadness. METHODS: We used a cross-sectional study and evaluated a total of 1464 Swedish students aged 15-17 (55.7% girls) to examine their frequency of NTT on social media, sleep parameters, and adolescent sadness. Bivariate and mediation analyses were performed. RESULTS: Approximately 60% (n = 882) of adolescents engaged in nighttime instant messaging, with 37% (n = 330) reporting texting every night. Higher frequency of NTT was significantly associated with later bedtimes (η2 > 0.12), extended weekend wake-up times (η2 = 0.07), increased social jetlag (η2 = 0.07), and reduced sleep duration on schooldays (η2 = 0.10). Multicategorical parallel mediation analyses revealed that sleep duration on schooldays had an indirect effect on the relationship between both Occasional NTT (a11b1 = 0.05, p < .05) and Daily NTT (a21b1 = 0.12, p < .05) with sadness. Mediation effects were not moderated by gender (p > .05), however, the association between Occasional NTT and higher sadness was significantly linked to boys (t = 2.72; p = .007). CONCLUSIONS: Findings showed a large percentage of adolescents engaging in nighttime social media use with worse quality of sleep, and underlined sleep duration on schooldays as a mediator associated with emotional problems in adolescents. These insights can aid in developing strategies for healthier habits to address the misuse of social media and prevent related health problems.

Concerns related to bodily integrity, medical mistrust, superstition, and disgust with respect to organ transplantation remain commonly cited barriers among African American, Caucasian, and Hispanic non-donors. The current study examined two narrative strategies for mitigating these barriers by eliciting feelings of happiness or sadness. African American, Caucasian, and Hispanic non-donors (N = 576) were randomly assigned to a radio ad that communicated either a recipient narrative or a waiting list narrative. As expected, the recipient narrative elicited greater feelings of happiness whereas the waiting list narrative aroused greater feelings of sadness. Moderated mediation analyses revealed models in which happiness, not sadness, was the mediator, such that the narrative frame was associated with ad persuasiveness. Additionally, only medical mistrust interacted with happiness to predict ad persuasiveness The results are discussed with an emphasis on message design strategies to employ among reluctant adult African American, Caucasian, and Hispanic potential donors.

BACKGROUND: Previous studies suggest an association between Post-concussion syndrome (PCS) and depression, both highly prevalent after mTBI. OBJECTIVE: To assess the prevalence and risk-factors of depression among patients with PCS 1 month after mTBI. METHODS: We prospectively screened 372 mTBI patients admitted in two academic Emergency Departments between 2017 and 2019. One month after mTBI, we administered the Rivermead Post-concussion symptoms Questionnaire (RPQ) and the Patient Health Questionnaire (PHQ-9) questionnaires over the telephone. PCS and depression were defined by RPQ ≥ 12 and PHQ-9 ≥ 10. Multivariate multinomial regression identified baseline factors associated with PCS and depression. RESULTS: Two hundred and eight completed RPQ and PHQ-9. Forty-seven patients (22.5%) met criteria for PCS, among which 22 (46.8%) met criteria for depression (PCS+D+). Patients with PCS but without depression were less likely to present with an associated injury (Coefficient = -1.6, p = 0.047) and to report initial sadness (Coefficient = -2.5, p = 0.03). Initial sadness (Coefficient = -1.3, p = 0.047), associated injury (Coefficient = -1.9, p = 0.008), as well as initial nausea (Coefficient = -1.8, p = 0.002), and male sex (Coefficient = 1.8, p = 0.002), were associated with the absence of depression and PCS in comparison with PCS+D+ patients. CONCLUSION: Among patients with PCS 1 month after mTBI, those with depression are more likely to present with initial sadness and with an associated injury.

Reading is one of the most common everyday activities, yet research elucidating how affective influence reading processes and outcomes is sparse with inconsistent results. To investigate this question, we randomly assigned participants (N = 136) to happiness (positive affect), sadness (negative affect), and neutral video-induction conditions prior to engaging in self-paced reading of a long, complex science text. Participants completed assessments targeting multiple levels of comprehension (e.g. recognising factual information, integrating different textual components, and open-ended responses of concepts from memory) after reading and after a week-long delay. Results indicated that the Sadness (vs. Happiness) condition had higher comprehension scores, with the largest effects emerging for assessments targeting deeper levels comprehension immediately after reading. Eye-tracking analyses revealed that such benefits may be partly driven by sustained attentional focus over the 20-minute reading session. We discuss results with respect to theories on affect, cognition, and text comprehension.

Parents and adolescents often hold discrepant perceptions of parental emotion socialization, which reflect misunderstandings in parent-adolescent communication on emotions and have potential detrimental effects on mental health of adolescents. The present study investigated the associations between parent-adolescent congruence and discrepancy in parental emotion socialization perception to two specific negative emotions (anger and sadness) and depressive symptoms in Chinese adolescents. A total of 372 adolescents (48.4% female, Mage = 13.43, SDage = 0.49) and their parents (79.6% mother, Mage = 41.15, SDage = 5.46) participated in this study. Both parents and adolescents reported perceived parental emotion socialization to anger and sadness, and adolescents reported depressive symptoms. Data were analyzed using polynomial regression and response surface analyses. Both congruence and discrepancy in parent and adolescent's reports were associated with adolescent depressive symptoms. A higher level of adolescent depressive symptoms was associated with higher parent-adolescent congruence in supportive responses to anger, sadness, and nonsupportive responses to anger. A higher level of depressive symptoms was associated with inconsistent reporting of supportive responses to sadness and nonsupportive responses to anger (only when parents had a more positive view than adolescents). This study highlights the significance of evaluating parent-child communication process by assessing perceived emotion socialization from both parents and adolescents and analyzing the reporting congruence and discrepancy. It also suggests that enhancing effective communication regarding parental emotion socialization could be a promising target for adolescent mental health promotion programs.

This study examined the relationships between positive/negative spirituality and meaning in life at two religious sites in Japan. Participants reported greater sadness and less meaning in life at Koyasan Okunoin, a temple with graves surrounded by nature, than at Nachi Kumano Taisha, a shrine with a waterfall. However, greater feelings of happiness protected meaning in life in the presence of sadness at Koyasan. Additionally, participants who felt a sense of awe reported greater meaning in life through self-liberation, regardless of the sites. The results provide new insights into meaning in life from the two sides of spirituality.

OBJECTIVE: This study aimed to determine whether HIV-Pain and Sadness Support (HIV-PASS), a collaborative behavioral health intervention based on behavioral activation, is associated with decreased pain-related interference with daily activities, depression, and other outcomes in people living with HIV. METHODS: We conducted a three-site clinical trial ( n = 187) in which we randomly assigned participants to receive either HIV-PASS or health education control condition. In both conditions, participants received seven intervention sessions, comprising an initial in-person joint meeting with the participant, their HIV primary care provider and a behavioral health specialist, and six, primarily telephone-based, meetings with the behavioral health specialist and participant. The intervention period lasted 3 months, and follow-up assessments were conducted for an additional 9 months. RESULTS: Compared with health education, HIV-PASS was associated with significantly lower pain-related interference with daily activities at the end of month 3 (our primary outcome; b = -1.31, 95% confidence interval = -2.28 to -0.34). We did not observe other differences between groups at 3 months in secondary outcomes that included worst or average pain in the past week, depression symptoms, anxiety, and perceived overall mental and physical health. There were no differences between groups on any outcomes at 12 months after enrollment. CONCLUSIONS: A targeted intervention can have positive effects on pain interference. At the end of intervention, effects we found were in a clinically significant range. However, effects diminished once the intervention period ended. TRIAL REGISTRATION: ClinicalTrials.gov NCT02766751.

Communication of emotions plays a key role in intraspecific social interactions and likely in interspecific interactions. Several studies have shown that animals perceive human joy and anger, but few studies have examined other human emotions, such as sadness. In this study, we conducted a cross-modal experiment, in which we showed 28 horses two soundless videos simultaneously, one showing a sad, and one a joyful human face. These were accompanied by either a sad or joyful voice. The number of horses whose first look to the video that was incongruent with the voice was longer than their first look to the congruent video was higher than chance, suggesting that horses could form cross-modal representations of human joy and sadness. Moreover, horses were more attentive to the videos of joy and looked at them for longer, more frequently, and more rapidly than the videos of sadness. Their heart rates tended to increase when they heard joy and to decrease when they heard sadness. These results show that horses are able to discriminate facial and vocal expressions of joy and sadness and may form cross-modal representations of these emotions; they also are more attracted to joyful faces than to sad faces and seem to be more aroused by a joyful voice than a sad voice. Further studies are needed to better understand how horses perceive the range of human emotions, and we propose that future experiments include neutral stimuli as well as emotions with different arousal levels but a same valence.

BACKGROUND: Anxiety, anger, and sadness are related to elevated ambulatory blood pressure (ABP), yet it is unclear whether each emotion exerts unique effects. Moreover, an understanding of who might be most susceptible to the negative effects of these emotions is limited, with the trait tendency to experience them or one's race as potential moderators. PURPOSE: The study examined the potential for differential effects of momentary anxiety, anger, and sadness on ABP. The study assessed whether a trait tendency to experience these negative emotions and/or race (Black vs. non-Black) would moderate these relationships. METHODS: Participants (n = 153) completed trait anxiety, anger, and depressive symptoms measures at baseline. ABP was collected over two 24-hour periods 3-4 months apart. Momentary measures of anxiety, anger, and sadness were assessed via ecological momentary assessment (EMA) after each ABP reading. RESULTS: Momentary anxiety consistently predicted diastolic blood pressure but not systolic blood pressure. Momentary anger and sadness did not predict blood pressure (BP). Conditional effects were found with momentary anxiety and anger predicting elevated BP in those individuals with trait anxiety/anger at its mean. Trait anxiety and depression consistently predicted heightened BP in Black participants. Trait anger did not moderate the relationships between negative emotions and ABP. CONCLUSIONS: Findings suggest that momentary anxiety and anger should be given attention as potential risk factors for hypertension and highlight the unique perspective of EMA methods. Black participants who were more anxious and depressed experienced heightened BP, with anxiety and depression providing possible intervention targets in improving racial disparities in cardiovascular health.

The outflow of the autonomic nervous system (ANS) is continuous and dynamic, but its functional organization is not well understood. Whether ANS patterns accompany emotions, or arise in basal physiology, remain unsettled questions in the field. Here, we searched for brief ANS patterns amidst continuous, multichannel physiological recordings in 45 healthy older adults. Participants completed an emotional reactivity task in which they viewed video clips that elicited a target emotion (awe, sadness, amusement, disgust, or nurturant love); each video clip was preceded by a pre-trial baseline period and followed by a post-trial recovery period. Participants also sat quietly for a separate 2-min resting period to assess basal physiology. Using principal components analysis and unsupervised clustering algorithms to reduce the second-by-second physiological data during the emotional reactivity task, we uncovered five ANS states. Each ANS state was characterized by a unique constellation of patterned physiological changes that differentiated among the trials of the emotional reactivity task. These ANS states emerged and dissipated over time, with each instance lasting several seconds on average. ANS states with similar structures were also detectable in the resting period but were intermittent and of smaller magnitude. Our results offer new insights into the functional organization of the ANS. By assembling short-lived, patterned changes, the ANS is equipped to generate a wide range of physiological states that accompany emotions and that contribute to the architecture of basal physiology.

OBJECTIVE: Individuals with eating disorders (EDs) often engage in maladaptive exercise (e.g., feeling driven, or to "compensate" for eating) which maintains eating pathology. Maladaptive exercise has been theorized to help individuals with EDs regulate emotions by enhancing positive affect (PA) and reducing negative affect (NA) associated with binge episodes and poor body image. However, no research has considered the presence of non-maladaptive exercise or evaluated this theory in binge-spectrum EDs. METHODS: This study evaluated affective trajectories pre- and post-exercise and examined exercise type (maladaptive or non-maladaptive) as a moderator. We recruited adults with binge-spectrum EDs (N = 107; n = 84 endorsed exercise) to complete a 7- to 14-day ecological momentary assessment protocol assessing NA (anxiety, guilt, and sadness), PA (excitement and cheerfulness), and exercise. RESULTS: There was a significant quadratic trajectory of PA pre-exercise, suggesting that the upward trajectory of PA leveled out as it moved closer to an exercise episode. Exercise type significantly moderated the cubic trajectory of PA post-exercise, such that the upward trajectory of PA accelerated in the hours following non-maladaptive exercise episodes while the downward trajectory of PA accelerated in the hours following maladaptive exercise episodes. No trajectories of NA demonstrated significant effects. CONCLUSIONS: Pre-exercise trajectories of PA may reflect positive expectancies around exercise. Post-exercise trajectories of PA suggest that non-maladaptive exercise promotes increased PA. Future research should evaluate when, and for whom, exercise serves to regulate affect and examine other momentary risk factors of exercise in EDs. PUBLIC SIGNIFICANCE: Individuals with EDs often engage in maladaptive exercise (e.g., feeling driven, or to "compensate" for eating). Maladaptive exercise has been theorized to help individuals with EDs regulate emotions. This study evaluated affective trajectories pre- and post-exercise and examined whether exercise type (maladaptive or non-maladaptive) changed these trajectories. Pre-exercise trajectories of PA may reflect positive expectancies around exercise. Post-exercise trajectories of PA suggest that non-maladaptive exercise promotes increased PA.
