The network analysis of anxiety, depression and academic burnout symptom relationships throughout early, middle, and late adolescence.

BACKGROUND: Previous research has explored the associations between anxiety, depression, and academic burnout primarily from a variable-level perspective. However, there is limited understanding of which symptoms might play a significant role in anxiety, depression, and academic burnout among adolescents at different stages. METHODS: This study included 7,286 adolescents aged 10 to 18. Questionnaires assessed participants' anxiety, depression, and academic burnout. Network analysis was conducted on the overall sample and segmented by early, middle, and late adolescence to explore relationships between symptoms and variations in symptom expression across these stages, aiming to propose effective interventions targeting anxiety, depression, and academic burnout symptoms in early, middle, and late adolescence. RESULTS: The study found that "feeling that studying is meaningless" emerged as a core symptom in the overall sample. Additionally, "acting or speaking slowly" emerged as a core symptom in early adolescence, while "the thought of dying or hurting" and "feeling bad about yourself, letting your family down" were prominent in middle adolescence, and "easily annoyed or irritable" and "feeling tired" may be prioritized in late adolescence. The varying central symptoms across different adolescent stages suggest the need for targeted interventions. CONCLUSION: These findings underscore the importance of interventions tailored to specific symptoms to meet the unique needs of adolescents at different developmental stages.

The Temporal Focus of Mind-Wandering and Chinese Adolescents' Well-Being.

The relationships between the temporal focus of mind-wandering (i.e., past-oriented and future-oriented mind-wandering) and well-being are important issues for adolescents, which may have significant implications on their well-being and self-identity development. However, few studies tested the temporal focus of mind-wandering and its emotional consequences in adolescents. In the present study, we conducted two studies using self-reported questionnaires from large sample sets to examine the relationships between the temporal focus of mind-wandering and hedonic (pleasure attainment) and eudaimonic (meaning pursuing) well-being among Chinese adolescents. Study 1 preliminarily tested the relationships between the temporal focus of mind-wandering and hedonic well-being among adolescents (n = 1273) suggesting that both past-oriented mind-wandering (PMW) and future-oriented mind-wandering (FMW) were positively correlated with hedonic well-being. Study 2 used a new sample (n = 986) and included another aspect of well-being (i.e., eudaimonic well-being), showing that PMW and FMW were both positively correlated with hedonic and eudaimonic well-being. Moreover, self-reflection mediated the relationships between FMW and hedonic/eudaimonic well-being, whereas self-reflection did not act as a mediator in the relationships between PMW and well-being. The present findings indicated that both PMW and FMW are beneficial for Chinese adolescents' well-being, and emphasized the mediating role of self-reflection in the relationships between FMW and well-being.

Are monetary gifts negatively labeled? Material benefits and prosocial motivation evaluation.

We examined whether people perceive prosocial actors' prosocial motivations differently when prosocial actors gain monetary gifts and goods gifts. Across five studies, 1351 participants read different prosocial scenarios that depicted prosocial actors who gained either monetary or goods gifts. Then, they evaluated the prosocial motivations of the prosocial actors. Studies 1-5 consistently found that people perceived prosocial motivations to be less authentic when prosocial actors chose to receive monetary gifts compared with goods gifts. In addition, moral disgust and moral character evaluation mediated this effect (Studies 3-4). Moreover, the negative effect of monetary gifts on people's perception of prosocial motivation further undermined their helping intention to prosocial actors (Study 5). Our research expanded the understanding of people's perception of material gifts in prosocial behavior by proposing the model of monetary benefits aggravated tainted altruism. Besides, our findings provide insights into public policy and charity rules.

Trait Empathy Modulates Patterns of Personal and Social Emotions During the COVID-19 Pandemic.

The COVID-19 pandemic has caused profound consequences on people's personal and social feelings worldwide. However, little is known about whether individual differences in empathy, a prosocial trait, may affect the emotional feelings under such threat. To address this, we measured 345 Chinese participants' personal emotions (e.g., active, nervous), social emotions (i.e., fearful and empathetic feelings about various social groups), and their empathy traits during the COVID-19 pandemic. Using the representational similarity analysis (RSA), we calculated the pattern similarity of personal emotions and found the similarity between the positive and negative emotions was less in the high vs. low empathy groups. In addition, people with high (vs. low) empathy traits were more likely to have fearful and sympathetic feelings about the disease-related people (i.e., depression patients, suspected COVID-19 patients, COVID-19 patients, flu patients, SARS patients, AIDS patients, schizophrenic patients) and showed more pattern dissimilarity in the two social feelings toward the disease-related people. These findings suggest a prominent role of trait empathy in modulating emotions across different domains, strengthening the polarization of personal emotions as well as enlarging social feelings toward a set of stigmatized groups when facing a pandemic threat.

The neural habituation to hedonic and eudaimonic rewards: Evidence from reward positivity.

Rewards play an important role in people's well-being. However, the mechanisms underlying neural habituation to hedonic rewards (attainment of pleasure) and eudaimonic rewards (attainment of meaning and self-realization) and their implications for longitudinal changes in well-being remain unknown. By operationalizing hedonic rewards as "winning money for oneself" and eudaimonic rewards as "winning money for a charity", 78 participants (41 women, aged from 17 to 24 years) completed a revised monetary gambling task during event-related potential (ERP) recording. Subsequently, the participants' well-being was measured after one year. The results showed that the reward positivity (RewP) effect readily decreased as the hedonic rewards were repeated, whereas the RewP effect in response to eudaimonic rewards was relatively sustained over time. Moreover, the declining RewP effect for repeated eudaimonic rewards was marginally positively associated with longitudinal decreases in well-being. These findings demonstrate at the neural level that sensitivity to repeated hedonic rewards is more prone to decrease than sensitivity to repeated eudaimonic rewards, and sustained eudaimonic reward sensitivity in the short term has greater implications for changes in well-being in the long term.

How does self name influence the neural processing of emotional prosody? An ERP study.

In this study, we investigated whether self-relevant information can accelerate the processing of emotional information. Our experiment, based on a passive auditory oddball paradigm, involved recording electroencephalography while participants listened to stimuli comprising their own names (ONs) and unfamiliar names (UNs) spoken with varying emotional prosody. At 220-300 ms, mismatch negativity (MMN) was more negative for ONs and angry prosody than for UNs and neutral prosody, respectively. These results suggest that attention is involuntarily attracted by ONs and emotional prosody, and that both types of information are given priority processing, even under pre-attentive conditions. Importantly, ONs with angry prosody induced more negative MMN than did similar UNs and ONs with neutral prosody, which indicates that the motivational significance embedded in angry prosody promotes the self-reference effect and, thus, involves more attention resources. At 300-500 ms, ONs triggered smaller P3a than did UNs, suggesting that less cognitive resources are required to process self-relevant information. These results suggest that self-relevant and emotional information of preferential processing interact with each other during the pre-attentive stage, with self-reference enhancing the processing of emotional information.

Your happy expressions encourage me to take risks: ERP evidence from an interpersonal gambling game.

Although the influence of endogenous emotion on decision-making has been widely studied, the effect of interpersonal emotions on risk decision-making is less understood. To address this issue, participants were asked to perform an interpersonal gambling game after perceiving their cooperator's facial emotions. The results found that the cooperator's happy expressions increased individuals' risk-approaching choice compared with angry expressions. Moreover, happy expressions induced larger P300 potentials in the option assessment stage, and diminished the differences between losses and wins in feedback-related FRN/RewP in the outcome valuation stage. Additionally, single-trial analysis found that the neural response induced by interpersonal expressions and feedback could predict participants' subsequent decision-making. These findings suggest that interpersonal emotions shape individuals' risk preference through enhancing in-depth valuation in the option assessment stage and early motivational salience valuation in the outcome valuation stage.

Self-choice preference: The propensity to under-delegate irrespective of sense of control.

People are more likely to make choices themselves than delegate to an agent, even when it may not be the most optimal decision based on a cost-benefit analysis. Previous studies have demonstrated that retaining authority and controllability might be the primary reason for preferring self-choice. The current study asks whether impairment of controllability associated with self-choice can increase the rate of delegation and whether there are self-other discrepancies in self-choice preference. In three studies, we directly manipulated participants' controllability associated with choice through literal instructions (experiment 1) and visual presentation (experiments 2 and 3). We found that participants showed a robust propensity to under-delegate even when they were aware of their impaired controllability associated with self-choice. Moreover, only 40% impairment of controllability (but not 20%) can decrease the propensity to under-delegate. This trend differed between decision-for-self and decision-for-other. These findings suggest that pursuing a sense of control cannot fully explain self-choice preference and appears to occur equally in decisions for oneself as well as for others.

Temporal dynamics of hedonic and eudaimonic reward processing: An event-related potentials (ERPs) study.

Reward or pleasure can be achieved from a hedonic approach (pleasure attainment) or eudaimonic approach (meaning and self-realization). However, the neurodynamics of hedonic and eudaimonic reward processing remain unclear. By operationalizing hedonic reward as "win money for oneself" and eudaimonic reward as "win money for charity", the current study used the monetary incentive delay task to parse hedonic and eudaimonic reward dynamics into the anticipatory and consummatory stages while event-related potentials (ERPs) were recorded. 24 participants (12 women) were recruited in this study. The results showed that in the anticipatory stage, the amplitudes evoked by hedonic and eudaimonic reward did not differ during early cue recognition (P2, N2), but they separated during late cue elaboration (cue-P3). In the consummatory stage, hedonic reward elicited a larger FRN effect, but eudaimonic reward elicited a larger fb-P3 effect. In addition, we also used the neural indices of hedonic and eudaimonic reward processing to predict participants' longitudinal changes in well-being (depression and positive emotion) across 6 months as exploratory in nature. Preliminary regression evidence suggested that greater differential amplitude of cue-P3 elicited by eudaimonic reward anticipation versus neutral anticipation positively predicted longitudinal increases in positive emotion. The findings elucidated specific substages of hedonic and eudaimonic reward processing and explored their potential roles in longitudinal changes in well-being.

Females Are More Sensitive to Opponent's Emotional Feedback: Evidence From Event-Related Potentials.

It is widely believed that females outperformed males in emotional information processing. The present study tested whether the female superiority in emotional information processing exists in a naturalistic social-emotional context, if so, what the temporal dynamics underlies. The behavioral and electrophysiological responses were recorded while participants were performing an interpersonal gambling game with opponents' facial emotions given as feedback. The results yielded that emotional cues modulated the influence of monetary feedback on outcome valuation. Critically, this modulation was more conspicuous in females: opponents' angry expressions increased females' risky tendency and decreased the amplitude of reward positivity (RewP) and feedback P300. These findings indicate that females are more sensitive to emotional expressions in real interpersonal interactions, which is manifested in both early motivational salience detection and late conscious cognitive appraisal stages of feedback processing.

Facial Expression Enhances Emotion Perception Compared to Vocal Prosody: Behavioral and fMRI Studies.

Facial and vocal expressions are essential modalities mediating the perception of emotion and social communication. Nonetheless, currently little is known about how emotion perception and its neural substrates differ across facial expression and vocal prosody. To clarify this issue, functional MRI scans were acquired in Study 1, in which participants were asked to discriminate the valence of emotional expression (angry, happy or neutral) from facial, vocal, or bimodal stimuli. In Study 2, we used an affective priming task (unimodal materials as primers and bimodal materials as target) and participants were asked to rate the intensity, valence, and arousal of the targets. Study 1 showed higher accuracy and shorter response latencies in the facial than in the vocal modality for a happy expression. Whole-brain analysis showed enhanced activation during facial compared to vocal emotions in the inferior temporal-occipital regions. Region of interest analysis showed a higher percentage signal change for facial than for vocal anger in the superior temporal sulcus. Study 2 showed that facial relative to vocal priming of anger had a greater influence on perceived emotion for bimodal targets, irrespective of the target valence. These findings suggest that facial expression is associated with enhanced emotion perception compared to equivalent vocal prosodies.

Pleasure attainment or self-realization: the balance between two forms of well-beings are encoded in default mode network.

What is a good life and how it can be achieved is one of the fundamental issues. When considering a good life, there is a division between hedonic (pleasure attainment) and eudaimonic well-being (meaning pursuing and self-realization). However, an integrated approach that can compare the brain functional and structural differences of these two forms of well-being is lacking. Here, we investigated how the individual tendency to eudaimonic well-being relative to hedonic well-being, measured using eudaimonic and hedonic balance (EHB) index, is reflected in the functional and structural features of a key network of well-being-the default mode network (DMN). We found that EHB was positively correlated with functional connectivity of bilateral ventral medial prefrontal cortex within anterior DMN and bilateral precuneus within posterior DMN. Brain morphometric analysis showed that EHB was also positively correlated with gray matter volume in left precuneus. These results demonstrated that the relative dominance of one form of well-being to the other is reflected in the morphometric characteristics and intrinsic functions of DMN.

Effects of Aging Stereotype Threat on Working Self-Concepts: An Event-Related Potentials Approach.

Although the influence of stereotype threat (ST) on working self-concepts has been highlighted in recent years, its neural underpinnings are unclear. Notably, the aging ST, which largely influences older adults' cognitive ability, mental and physical health, did not receive much attention. In order to investigate these issues, electroencephalogram (EEG) data were obtained from older adults during a modified Stroop task using neutral words, positive and negative self-concept words in aging ST vs. neutral control conditions. Results showed longer reaction times (RTs) for identifying colors of words under the aging ST compared to the neutral condition. More importantly, the negative self-concept elicited more positive late P300 amplitudes and enhanced theta band activities compared to the positive self-concept or neutral words under the aging ST condition, whereas no difference was found between these self-concepts and neutral words in the control condition. Furthermore, the aging ST induced smaller theta band synchronization and enhanced alpha band synchronization compared to the control condition. Moreover, we also observed valence differences in self-concepts where the negative self-concept words reduced early P150/N170 complex relative to neutral words. These findings suggest that priming ST could activate negative self-concepts as current working self-concept, and that this influence occurred during a late neural time course.

Emotional Intensity Modulates the Integration of Bimodal Angry Expressions: ERP Evidence.

Integration of information from face and voice plays a central role in social interactions. The present study investigated the modulation of emotional intensity on the integration of facial-vocal emotional cues by recording EEG for participants while they were performing emotion identification task on facial, vocal, and bimodal angry expressions varying in emotional intensity. Behavioral results showed the rates of anger and reaction speed increased as emotional intensity across modalities. Critically, the P2 amplitudes were larger for bimodal expressions than for the sum of facial and vocal expressions for low emotional intensity stimuli, but not for middle and high emotional intensity stimuli. These findings suggested that emotional intensity modulates the integration of facial-vocal angry expressions, following the principle of Inverse Effectiveness (IE) in multimodal sensory integration.

Response inhibition or evaluation of danger? An event-related potential study regarding the origin of the motor interference effect from dangerous objects.

Previous studies have identified an interference effect from dangerous objects on prepared responses. However, its origin remains arguable. This study investigated the neural processes of this motor interference effect. The design adopted a motor priming paradigm mixed with a Go/NoGo task. Pictures of a left or right hand were used as primes, and green (Go signal) or red (NoGo signal) circles superimposed on dangerous or safe objects were used as targets. Participants were instructed to prepare the corresponding key press using the hand that was consistent with the handedness of the prime and not to execute until a Go signal appeared. Behavioral results indicated longer reaction times and a trend that participants made more errors for the dangerous condition than for the safe condition in the Go trials. However, the difference between the error rates for the dangerous and safe conditions did not emerge in the NoGo trials. Event-related potential analysis revealed a similar effect on the P3 component, which may reflect an assignment of cognitive resources to evaluate danger. More positive parietal P3 amplitudes were identified in response to the dangerous condition in the Go trials. However, the difference in the P3 amplitudes between the dangerous and safe conditions was not significant in the NoGo trials. Together, the motor interference effect from dangerous objects may originate from the danger evaluations. Furthermore, differences between the dangerous and safe conditions also emerged in the P1, posterior N1, P2, and posterior N2 components; the possible processes that underlie these components were discussed.

The neural dynamics underlying the interpersonal effects of emotional expression on decision making.

Although numerous studies explore the effects of emotion on decision-making, the existing research has mainly focused on the influence of intrapersonal emotions, leaving the influence of one person's emotions on another's decisions underestimated. To specify how interpersonal emotions shape decision-making and delineate the underlying neural dynamics involved, the present study examined brain responses to utilitarian feedback combined with angry or happy faces in competitive and cooperative contexts. Behavioral results showed that participants responded slower following losses than wins when competitors express happiness but responded faster following losses than wins when cooperators express anger. Importantly, angry faces in competitive context reversed the differentiation pattern of feedback-related negativity (FRN) between losses and wins and diminished the difference between losses and wins on both P300 and theta power, but only diminished the difference on FRN between losses and wins in cooperative context. However, when partner displays happiness, losses versus wins elicited larger FRN and theta power in competitive context but smaller P300 in both contexts. These results suggest that interpersonal emotions shape decisions during both automatic motivational salience valuation (FRN) and conscious cognitive appraisal (P300) stages of processing, in which different emotional expressions exert interpersonal influence through different routes.

High working memory load impairs the effect of cognitive reappraisal on emotional response: Evidence from an event-related potential study.

This study investigates how the working memory (WM) load influenced the efficacy of cognitive reappraisal, a frequently used strategy for emotion regulation. In a dual-task paradigm, the participants were required to perform a high-load or a low-load memory task and simultaneously reappraise aversive pictures with a negative or a neutral meaning. In the low-load condition, we found that the amplitude of emotion-enhanced late positive potential (LPP) was significantly decreased by neutral reappraisal compared to negative reappraisal. In the high-load condition, this regulatory effect of reappraisal disappeared. These results suggest that successful reappraisal relies on cognitive resources and WM processes. If the necessary resources involved in reappraisal are over-depleted by a concurrent memory task, the reappraisal effect will be impaired. Moreover, we found that emotion-enhanced LPP was significant in both of the high-load and low-load tasks, which suggests that emotional electrocortical response may not be susceptible to the available resources.

Well-being and Anticipation for Future Positive Events: Evidences from an fMRI Study.

Anticipation for future confers great benefits to human well-being and mental health. However, previous work focus on how people's well-being correlate with brain activities during perception of emotional stimuli, rather than anticipation for the future events. Here, the current study investigated how well-being relates to neural circuitry underlying the anticipating process of future desired events. Using event-related functional magnetic resonance imaging, 40 participants were scanned while they were performing an emotion anticipation task, in which they were instructed to anticipate the positive or neutral events. The results showed that bilateral medial prefrontal cortex (MPFC) were activated during anticipation for positive events relative to neutral events, and the enhanced brain activation in MPFC was associated with higher level of well-being. The findings suggest a neural mechanism by which the anticipation process to future desired events correlates to human well-being, which provide a future-oriented view on the neural sources of well-being.

Influence of attention on bimodal integration during emotional change decoding: ERP evidence.

Recent findings on audiovisual emotional interactions suggest that selective attention affects cross-sensory interaction from an early processing stage. However, the influence of attention manipulation on facial-vocal integration during emotional change perception is still elusive at this point. To address this issue, we asked participants to detect emotional changes conveyed by prosodies (vocal task) or facial expressions (facial task) while facial, vocal, and facial-vocal expressions were presented. At the same time, behavioral responses and electroencephalogram (EEG) were recorded. Behavioral results showed that bimodal emotional changes were detected with shorter response latencies compared to each unimodal condition, suggesting that bimodal emotional cues facilitated emotional change detection. Moreover, while the P3 amplitudes were larger for the bimodal change condition than for the sum of the two unimodal conditions regardless of attention direction, the N1 amplitudes were larger for the bimodal emotional change condition than for the sum of the two unimodal conditions under the attend-voice condition, but not under the attend-face condition. These findings suggest that selective attention modulates facial-vocal integration during emotional change perception in early sensory processing, but not in late cognitive processing stages.

The integration of facial and vocal cues during emotional change perception: EEG markers.

The ability to detect emotional changes is of primary importance for social living. Though emotional signals are often conveyed by multiple modalities, how emotional changes in vocal and facial modalities integrate into a unified percept has yet to be directly investigated. To address this issue, we asked participants to detect emotional changes delivered by facial, vocal and facial-vocal expressions while behavioral responses and electroencephalogram were recorded. Behavioral results showed that bimodal emotional changes were detected with higher accuracy and shorter response latencies compared with each unimodal condition. Moreover, the detection of emotional change, regardless of modalities, was associated with enhanced amplitudes in the N2 and P3 component, as well as greater theta synchronization. More importantly, the P3 amplitudes and theta synchronization were larger for the bimodal emotional change condition than for the sum of the two unimodal conditions. The superadditive responses in P3 amplitudes and theta synchronization were both positively correlated with the magnitude of the bimodal superadditivity in accuracy. These behavioral and electrophysiological data consistently illustrated an effect of audiovisual integration during the detection of emotional changes, which is most likely mediated by the P3 activity and theta oscillations in brain responses.
