Online assessment in young children: Challenges and considerations
In the years following the COVID-19 pandemic, online assessment has emerged as an increasingly popular method for testing children. This review aims to review key advantages and disadvantages of online assessment in young children, specifically in the area of literacy and mathematics assessment. We first consider the recent history of online assessment and give evidence from our own experiences with online assessments in both Cebu, Philippines and Hong Kong. We then discuss the benefits of conducting assessments online. One of the key strengths of online assessments is the efficient use of resources, such as ease of staff training, increased participation and decreased costs for both participants and researchers. Difficulties related to testing environment, parental interference and exclusion of certain populations are also highlighted as focal challenges that must be considered when designing and implementing online assessment. The reliability and validity of online assessments are then specifically discussed in relation to the question of how to best ensure that online measures function as intended, stressing the importance of establishing separate norms for the various administration modes. Notably, online assessments delivered via phone screen must have separate norms than those delivered on a computer screen, as device differences may account for differences in performance. Finally, we present broader considerations for designing online assessments with young children. This includes practical tips for pilot testing, user interface design, data confidentiality and automatic scoring, both to enhance the efficiency of future online assessments and increase participation. Specifically, online assessments for children must account for their developing attentional abilities, meaning assessments should be brief, engaging and contain clear task instructions. The implementation of these considerations will support the development of more reliable, valid and inclusive assessments which will allow researchers and practitioners to support equitable and feasible online testing moving forward.
Validation and Application of Functions of Future Thinking Scale in Chinese Adults
Future thinking, mentally projecting oneself into future events, scenarios, and circumstances, is common in everyday life. However, no scale has been developed to explore the functions of future thinking in China. This study aimed to validate the Chinese version of the functions of future thinking scale (FoFTS). Based on a sample of 578 Chinese residents, confirmatory factor analysis results indicated that the 10-factor structure of the Chinese version of FoFTS fit well. The reliability indexes across 10 factors were in an acceptable range. Acceptable convergent validity was reported considering its association with time perspective, future self-continuity, emotion regulation, and intertemporal decision-making. Additionally, the effect of age and the severity of emotional states on FoFTS were found. Overall, the Chinese FoFTS is a reliable and valid tool for examining the diverse purposes and roles of future thinking among Chinese adults, thereby enhancing the cross-cultural study of purposes for future thinking.
Influence of reinforcement learning on the inhibitory control of Internet gaming disorder
Reward processing dysfunction and inhibition control deficiency have been observed in Internet gaming disorder (IGD). However, it is still unclear whether the previous reinforcement learning depends on reward/punishment feedback influences on the cognitive inhibitory control of IGD. This study compared the differences between an IGD group and healthy people without game experiences in the probability selection task and the subsequent stop signal task by the method of behavioral experiments, in order to explore whether the reward learning ability is impaired in the IGD group. We also discuss the influence of previous reward learning on subsequent inhibition control. The results showed that (1) during the reward learning phase, the IGD group's accuracy was significantly lower than that of the control group; (2) compared with the control group, the IGD group's reaction times were longer in the transfer phase; (3) for no-go trials of the inhibitory control phase after reward learning, the accuracy of the reward-related stimulation in the IGD group was lower than that of punishment-related or neutral stimulation, but there was no significant difference among the three conditions in the control group. These findings indicated that the reinforcement learning ability of the IGD group was impaired, which further caused the abnormal response to reinforcement stimuli.
The Effects of Mindfulness on Shame: Exploring Mediation by Cognitive Flexibility and Self-Compassion in a Chinese Adult Population
To examine the effects of mindfulness on shame and the mechanisms mediated by cognitive flexibility and self-compassion in a Chinese adult population in daily life, we conducted two studies. Study 1 was a cross-sectional study using the Five-Factor Mindfulness Questionnaire, the Cognitive Flexibility Inventory, the Self-Compassion Scale, and the Self-Conscious Affect-3, which were administered to 481 adults in Beijing and Chengdu. For Study 2, an 8-month follow-up study was conducted on 128 of the adults. The results of Study 1 showed that (1) the awareness of action and nonjudgment dimensions, and the total score of mindfulness were significantly correlated with shame; (2) cognitive flexibility and self-compassion could fully mediate the prediction of mindfulness on shame. The Study 2 showed that (1) mindfulness and shame were significantly negatively correlated in both phases of measurement; (2) controlling for T1 shame, T1 mindfulness was able to negatively predict T2 shame; controlling for T1 mindfulness, T1 shame was not able to predict T2 mindfulness. There is a longitudinal association between mindfulness and shame, and only mindfulness scores are predictive of the shame and not vice-versa; both cognitive flexibility and self-compassion can provide explanations for the prediction of shame by mindfulness. Enhancing levels of mindfulness can help alleviate individuals' shame levels.
Conscious vision in blindness: A new perceptual phenomenon implemented on the "wrong" side of the brain
Patients with lesions in the visual cortex are blind in corresponding regions of the visual field, but they still may process visual information, a phenomenon referred to as residual vision or "blindsight". Here we report behavioral and fMRI observations with a patient who reports conscious vision across an extended area of blindness for moving, but not for stationary stimuli. This completion effect is shown to be of perceptual and not of conceptual origin, most likely mediated by spared representations of the visual field in the striate cortex. The neural output to extra-striate areas from regions of the deafferented striate cortex is apparently still intact; this is, for instance, indicated by preserved size constancy of visually completed stimuli. Neural responses as measured with fMRI reveal an activation only for moving stimuli, but importantly on the ipsilateral side of the brain. In a conceptual model this shift of activation to the "wrong" hemisphere is explained on the basis of an imbalance of excitatory and inhibitory interactions within and between the striate cortices due to the brain injury. The observed neuroplasticity indicated by this shift together with the behavioral observations provide important new insights into the functional architecture of the human visual system and provide new insight into the concept of consciousness.
Can irrelevant self-related information in working memory be actively suppressed?
To utilize the resource of working memory efficiently, the brain actively suppresses irrelevant information to focus cognitive resources on the task at hand. However, whether task-irrelevant self-related information can be suppressed is still an open question. This study explores the inhibitory effects of various types of identity-associated information (self, friend, stranger) with an irrelevant distracting paradigm, in which participants are required to memorize the color while ignoring the shape during a memory array. In the subsequent test array, participants are asked to judge whether the color of the test item is the same as the memorized one, while the ignored shape features could also change. The results are as follows. (1) Self-associated information survived the inhibitory effect no matter whether the interstimulus interval (ISI) was short or long. (2) Stranger-associated information remained inhibitory effect in a long ISI (3000 ms). The results indicate that self-associated information can bypass the executive system and remain active in working memory processing.
The association between social support and prosocial behavior: A three-level meta-analysis
Numerous studies have examined the relationship between social support and prosocial behavior and have concluded that social support is an important factor in generating prosocial behavior. However, different studies have produced different conclusions, and the moderating effect on the relationship is not entirely clear. The current study uses a three-level meta-analysis method to clarify the relationship between social support and prosocial behavior, and explores the moderating variables that affect the relationship between the two variables. Through a systematic literature search, a total of 92 studies, 418 effect sizes, and 74,378 participants were obtained. The main effects test found a significant positive correlation between social support and prosocial behavior. Tests of the moderating effects indicated that the relationship between social support and prosocial behavior was moderated by year of publication, source of social support, measurement of social support and measurement of prosocial behavior. In summary, social support plays an important role in prosocial behavior, and exploring their relationship is beneficial to families, schools and society in guiding individuals' prosocial behavior.
Acquiring musical knowledge increases music liking: Evidence from a neurophysiological study
People possessing musical knowledge tend to enjoy music more, but the linkage remains to be determined. Based on the shared affective motion experience model for music appreciation, we hypothesized that acquiring musical knowledge about the music itself, for example, an analytical understanding of music elements and the related emotional expressions, would increase music liking. To test the hypothesis, we asked 48 participants to learn analytical or historical information about a piece of music by watching a pre-recorded teaching video. Learners' physiological responses, such as skin conductance and heart rate, were recorded during learning. The increase of music liking was observed after both types of knowledge acquisition, but more so for analytical knowledge. Notably, acquiring analytical knowledge made learners' skin conductance more similar, indicating the alignment of physiological responses. This physiological similarity, correlated with analytical knowledge similarity, could mediate the effect of knowledge acquisition on music liking. In sum, this study reveals the impact of analytical knowledge on music enjoyment and the associated neurophysiological mechanism. It extends the theoretical framework of shared affective motion experience to explain how musical knowledge influences music appreciation.
The Impact of Social Stress on Trustworthiness Judgments in Schizophrenia
The present study examines the impact of induced social stress on facial trustworthiness judgments in individuals with schizophrenia (SCZ) and the associations between symptoms and trustworthiness ratings. Thirty-three individuals with SCZ and forty healthy controls (HC) were asked to rate the trustworthiness of 24 digitally morphed faces in two counterbalanced conditions. Mild social stress was induced by listening to loud noises from a busy street. BPRS, CAPE-42, and the Paranoia Scale measured the severity of symptoms. We did not observe significant differences in trustworthiness judgments between the patient and control groups. Social stress did not impact trust judgments. Paranoia was negatively connected to trustworthiness ratings in the control group. Subjective rating of stress in noise condition was negatively associated with paranoia only in the control sample. In the patient group, a negative correlation was found between trustworthiness ratings in stress conditions and the severity of self-reported negative symptoms. Our results suggest that mild social stress does not significantly affect trustworthiness judgments in either patients with SCZ or in HC. Differences between the patient and control groups in trustworthiness judgments were negligible. Overall, the results of this study can be considered mainly negative and contrast with previous studies. The stress induction paradigm or a smaller sample size might cause observed results. In controls, biased face perception was linked to trait paranoia. By contrast, in SCZ, other factors might impact trust perception and need further examination.
The Guanxi mediating role linking organizational justice to contextual performance with age as a moderator
Guanxi, a distinctive Chinese concept, reflects a shared vision of relationships and connections that include mutual understanding, trust, and a deep bond between individuals. Recognized for its potency in shaping the relationships that facilitate business undertakings and access to key resources, Guanxi is postulated as a potential mediator in the nexus between organizational justice and contextual work performance. The depth of Guanxi, intertwined with Chinese culture and values, may be perceived differently across age groups. Specifically, as Chinese millennials usually interact with global paradigms, generational disparities might emerge in valuing these traditional constructs. This study delves into how the dimensions of Guanxi-Ganqing (emotional connection), Renqing (reciprocity), and Xinren (loyalty)-mediate the relationship between organizational justice and contextual work performance, with chronological age as a moderator. The present study includes a convenience sample of 630 Chinese employees, aged 22-67 years, who participated in a quantitative online survey. The findings endorse the mediation role of Guanxi. The total influence of justice was found to be significant, as well as the indirect impacts, that were statistically salient. Although the age-moderated mediation was not wholly substantiated, the age-specific indirect effects of Renqing and Xinren did present significant variances between millennials and those above 42 years. The relevance of this study extends beyond the academic field, shedding light on the cultural dynamics at play within Chinese organizational settings. By unveiling the relationships between Guanxi, organizational justice, and performance, and by elucidating the age-specific variations therein, this research provides insights for organizational leaders and human resource professionals. Based on these findings, businesses can craft targeted interventions that capitalize on the strengths of Guanxi, ensuring fair practices and enhancing performance across diverse age groups. Further, recognizing the unique attributes and values of different generational cohorts can aid in fostering a harmonious, culturally attuned, and efficient workplace environment.
The technique of transforming symptom's symbol into emptiness: A mind-body therapy in the Chinese context
The technique of transforming symptom's symbol into emptiness (TSSE) is a new mind-body treatment method proposed by Tianjun Liu in 2008. It integrates Qigong and concrete object-image thinking rooted in traditional Chinese culture into modern psychotherapy and proposes that mental and physical problems can be alleviated or eliminated in the process of movement. Accordingly, the therapist needs to guide the client with various symptoms to psychological nothingness where the client cannot see or feel these symptoms, and the purpose of healing can be achieved through the experience of emptiness. TSSE is divided into static and dynamic operations and consists of 10 steps. The static operation includes trio relaxation exercises (the body, breath, and mind), identifying the target symptom, visualizing the target symptom as an object-image, visualizing a symbolic carrier, and filling out record sheet A. The dynamic operation includes trio relaxation exercises again, moving the symbolic object into the carrier, moving the carrier with the symbolic object into psychological nothingness, moving back and assessment, and filling out record sheet B. The effectiveness of TSSE can be evaluated by the therapist's judgment based on the client's performance and by the difference between the symptom impact scores recorded in sheets A and B. TSSE has been proven to be an effective psychosomatic treatment solution by some empirical studies conducted in China. Future research can combine other technologies, such as fMRI and fNIRS, to further explore the potential effective mechanisms of TSSE.
The Psychologically Rich Life Questionnaire in China
Research on psychological richness in China and in adolescents is limited. We validated the 17-item Psychologically Rich Life Questionnaire in a sample of 1794 Chinese high school students. Internal consistency was adequate, and a two-factor structure was found.
Unraveling the Intricacies of Curiosity: A Comprehensive Study of Its Measures in the Chinese Context
Curiosity, as the strong desire to acquire new information, plays a crucial role in human behaviors. While recent research has delved into the effects, behavioral manifestations, and neural underpinnings of curiosity, the absence of standardized assessment tools for measuring curiosity may hinder advancements in this field. Here, we translated different curiosity scales into Chinese and tested each translated scale by examining its reliability and structural validity. Our results showed that the scores derived from these scales have comparable reliability to those original versions. The confirmatory factor analysis results of the curiosity scales were consistent with previous results. We also found significant associations between different types of curiosity within taxonomy and demonstrated that personality traits such as impulsive sensation seeking, intolerance of uncertainty, and openness can jointly predict trait curiosity. Additionally, we confirmed the social dimension of curiosity, showing that loneliness partially mediates the relationship between social anxiety and social curiosity. This study provides validated Chinese versions of curiosity scales and elucidates the mechanisms of curiosity from multiple perspectives, potentially advancing curiosity research in the Chinese and cross-cultural contexts.
Neural Tracking to Auditory Statistical Structures in Children
Children's brain is able to track the linguistic structures in continuous speech. When there was no prior knowledge, we found that children also automatically detected and tracked the statistical structures in auditory tone steam as reflected by neural entrainment, but their ability was immature.
Stronger Empathy and Better Peer Relationship? One-Year Cross-Lagged Panel Analysis in Preschoolers
The development of empathy and the establishment of peer relationships significantly influence the quality of preschoolers' social lives. Past research consistently demonstrates a strong correlation between empathy and peer relationships. However, debates persist regarding causality. To provide evidence on this matter, we conducted a year-long longitudinal study involving 160 preschoolers at T1, with 137 children (mean age = 60.99 months, SD = 3.51; 66 males) retained at T2, 1 year later. Our study employed a two-wave design and cross-lagged panel analysis. Data on empathy and peer relationships were collected through empathy story tasks and peer nominations. For the analysis of peer nominations, we selected three centrality measures from social network analysis: degree centrality (number of direct friendships), closeness centrality (proximity between network members), and betweenness centrality (control/mediation of information exchange). Results from the cross-lagged panel analysis reveal that preschoolers' affective and cognitive empathy at T1 positively and significantly predict peer relationships at T2. Specifically, both forms of empathy predict degree centrality and closeness centrality. Additionally, hierarchical linear modeling indicates that, even after controlling for affective empathy, cognitive empathy significantly predicts both degree centrality and closeness centrality at T2. These findings underscore the importance of nurturing empathy, especially cognitive empathy, to enhance peer relationships among preschoolers. Consequently, educators can play a vital role in improving peer relationships by intervening in empathy development, promoting greater social interaction.
Attention enhances short-term monocular deprivation effect
Patching one eye of an adult human for a few hours has been found to promote the dominance of the patched eye, which is called short-term monocular deprivation effect. Interestingly, recent work has reported that prolonged eye-specific attention can also cause a shift of ocular dominance toward the unattended eye though visual inputs during adaptation are balanced across the eyes. Considering that patching blocks all input information from one eye, attention is presumably deployed to the opposite eye. Therefore, the short-term monocular deprivation effect might be, in part, mediated by eye-specific attentional modulation. Yet this question remains largely unanswered. To address this issue, here we asked participants to perform an attentive tracking task with one eye patched. During the tracking, participants were presented with both target gratings (attended stimuli) and distractor gratings (unattended stimuli) that were distinct from each other in fundamental visual features. Before and after one hour of tracking, they completed a binocular rivalry task to measure perceptual ocular dominance. A larger shift of ocular dominance toward the deprived eye was observed when the binocular rivalry testing gratings shared features with the target gratings during the tracking compared to when they shared features with the distractor gratings. This result, for the first time, suggests that attention can boost the strength of the short-term monocular deprivation effect. Therefore, the present study sheds new light on the role of attention in ocular dominance plasticity.
Psychometric evaluation of the Geneva Sentimentality Scale in Chinese college students
The Geneva Sentimentality Scale (GSS) measures the experience of being moved and its effects on behavior. Despite the prevalence of this emotional response, it has not been extensively studied in China. This study aims to adapt and revise the GSS for Chinese college students to assess its cross-cultural consistency. A sample of 1328 students aged 18-24 years participated in the study, with 127 randomly selected for retesting after an 8-week interval. Exploratory factor analysis reveals that the Chinese version of the GSS includes three factors (emotional labels, tears of joy, and warm feelings in the chest), with a total of nine items. The internal consistency coefficients for the three factors and the overall scale are high, and the total score remains stable over time. Confirmatory factor analysis (CFA) shows that the three-factor model has a good fit. Multigroup CFA indicates measurement invariance across genders. The results also demonstrate good discriminant and convergent validity for the scale. Overall, the GSS is a reliable and flexible tool for assessing the emotion of being moved among Chinese college students.
Influences of tea consumption on self-rated health and life satisfaction among older adults: Evidence from the CLHLS
The benefits of tea consumption as a special diet for health and life satisfaction have attracted considerable attention; however, it is not clear whether the effect of tea consumption on self-rated health (SRH) and self-rated life satisfaction (SRL) is equal among all types of tea, and it is unclear whether these associations are impacted by gender and age in older adults. This study aimed to examine the associations between tea consumption, SRH and SRL in older adults and to explore the role of gender and age. Participants aged 65-105 (N = 78,345) were interviewed in the years 2002, 2005, 2008, 2011, 2014 and 2018 in the Chinese Longitudinal Healthy Longevity Study (CLHLS). Generalized estimation equations (GEE) with the identity link function were adopted to estimate the cross-sectional associations of tea consumption with SRH and SRL. GEE with the logic link function were used to explore the longitudinal associations of tea consumption with SRH decline and SRL decline. Drinking tea at present, especially scented tea, was significantly associated with better SRH and SRL for older adults. Male participants benefited more from tea consumption than females, and the protective effect of green tea consumption on improving SRH and SRL in males was evident. Older adults aged 90-105 with current tea consumption daily had better SRH and reduced risk of SRL decline.
Mindfulness affected post-traumatic stress symptoms and post-traumatic growth: Adaptive and maladaptive sides through trauma-related shame and guilt
Mindfulness plays an important role in reducing post-traumatic stress symptoms (PTSS) and promoting posttraumatic growth (PTG) among traumatized populations. However, the mechanism at the emotional level has not been fully examined. Thus, we aimed to investigate the possible mediating roles of trauma-related shame and guilt. A total of 814 college students (M = 19.55, SD = 1.89) with traumatic experiences in China were recruited. Traumatic experiences, mindfulness, trauma-related shame, and trauma-related guilt were assessed in the first survey. Six months later, PTSS and PTG were assessed in the second survey. Structural equation modeling (SEM) analysis indicated that mindfulness was associated with less PTSS through shame and guilt. However, though directly associated with more PTG, mindfulness could also negatively predict PTG by evoking less guilt. Mindfulness can be a way to cope with traumatic experiences and related psychological consequences. However, although mindfulness can reduce PTSS by suppressing negative trauma-related shame and guilt, it can also limit the realization of PTG by inhibiting the adaptive sides of these emotions.
Interaction between tea consumption and genes on activities of daily living disability in older adults
The effects of tea consumption on delaying aging and the onset of age-related disabilities have been reported; however, it is unclear whether these benefits are impacted by genes. This study aimed to examine the associations between tea consumption and activities of daily living (ADL) and explore the role of genetic factors. Data from 46,487 older adults aged 64-105 who participated in at least one data wave of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) conducted in 2002, 2005, 2008, 2011, 2014, and 2018 were analyzed. Genetic data were produced using the Affymetrix Axiom™myDesign™ (384-format) Human Genotyping Array. The generalized estimation equation and multiple logistic regression models were constructed to examine the effects of tea consumption, polygenic risk score, and their interactions on ADL. Tea consumption was related to reduced ADL decline-the effect was statistically significant among men but not women. A significant interaction between tea consumption and polygenic risk score (PRS) was observed. Tea consumption was associated with a decreased risk of ADL disability only among individuals with a low PRS. These findings indicate that tea consumption plays a role in preventing disability in older adults with low polygenic risk.
The temporal dynamics of perceived stress and depression in college students: An ecological momentary assessment
Previous studies have implied that stress is a risk factor for depression, but relatively little is known about how healthy individuals' stress dynamically affects depression as a mood in daily life. Therefore, an ecological momentary assessment study was conducted among 141 college students to test the temporal dynamic effect of daily perceived stress on depression and the underlying mediating and moderating role of rumination. Perceived stress, state rumination, and depression were measured using self-compiled questionnaire three times a day over 12 days. Trait rumination was measured with the Nolen-Hoeksema Ruminative Response Scale. Hierarchical linear models with HLM 7.0 were adopted to examine the mediation and moderation effects. In the mediation model, the greater the daily perceived stress at time t, the higher the state rumination at time t + 1, and state rumination at t + 1 positively predicted college students' depression at t + 2. In the moderation model, trait rumination significantly facilitated perceived stress-induced depression. These results verified that daily perceived stress could affect college students' depression directly or indirectly through the critical mediating mechanism of state rumination, and this effect would be exacerbated with a higher level of trait rumination.
The relationship between college students' belief in a just world and online prosocial behavior
Previous studies have highlighted the critical role that the belief in a just world (BJW) plays in maintaining and promoting prosocial behaviors within individuals. Considered a stable personality trait, the crux of BJW lies in the conviction that individuals receive what they deserve, and deserve what they receive. Simultaneously, the relationship between BJW and prosocial behavior is impacted by an individual's sense of fairness or unfairness. However, past research has primarily focused on real-life prosocial behavior, with limited exploration into the relationship between BJW and online prosocial behavior. This study, comprising a survey and an experiment, aimed to delve deeper into this relationship. The survey section randomly selected 4212 college students to examine how BJW correlates with online prosocial behavior. Findings predominantly revealed a significant positive correlation between online prosocial behavior and BJW. Additionally, the study explored how gender and place of origin influence these behaviors. Results showed that male students and those from urban areas exhibited significantly higher online prosocial behavior. The experimental research investigated the performance differences in online prosocial behaviors among college students under different fairness scenarios, revealing that the online prosocial behavior in an unfair situation was significantly higher than in fair or neutral situations. Furthermore, in unfair situations, a significant correlation was observed between BJW and online prosocial behavior. The findings from this study significantly advance our understanding of the dynamics between BJW and online prosocial behavior among college students, emphasizing that perceived injustices can markedly enhance prosocial behaviors in virtual settings. This study underscores the profound impact of fairness perceptions and highlights the modulating effects of gender and geographical background on online interactions.
Distributive fairness during the transition to adolescence: The role of peer comparison and social value orientation
Combining the dictator game (DG) and the ultimatum game (UG), this study recruited 546 Chinese children (321 boys, aged 9-12 years) as distributors, and found that both peer comparison and social value orientation (SVO) significantly influenced children's distributive fairness from late childhood to early adolescence. Results showed that as the unfairness of peer proposals increased, participants decreased the amount of gold coins distributed to the receiver in both tasks, revealing a peer comparison effect. This effect was more pronounced for adolescents than for children in both tasks. In addition, participants' fair distribution behaviors in the DG showed a three-way interaction effect of SVO, grade, and peer comparison. Specifically, for proselfs, children were not influenced by peers and consistently proposed self-interested distributions, whereas adolescents exhibited a peer comparison effect; for prosocials, both children and adolescents were influenced by peers, but children decreased the amount of their distributions only when they saw peers make extremely unfair distributions, whereas adolescents decreased the amount of their distributions when they saw peers make both mildly and extremely unfair distributions. This study highlights the importance of social environment and personal trait in shaping children's fair distribution behavior during the transition from late childhood to early adolescence.
Peripheral nerve stimulation for lower-limb postoperative recovery: A systematic review and meta-analysis of randomized controlled trials
Patients undergoing lower-limb orthopedic surgery may experience multiple postoperative complications. Although peripheral nerve stimulation (PNS) is a promising non-pharmacological approach that has been used in lower-limb postoperative recovery, the clinical efficacy of PNS remains inconclusive. This study systematically searched three databases (PubMed, Embase, and Cochrane Library) for randomized controlled trials (RCTs) that examined the treatment effects of PNSs in patients who underwent lower-limb orthopedic surgery up to September 29, 2023. Two investigators independently identified studies, extracted data, and conducted meta-analyses with Review Manager 5.4. The outcomes were pain relief (measured by reductions in pain intensity and analgesic consumption) and functional improvements (range of motion [ROM] and length of hospitalization [LOH]). A total of 633 patients including 321 in the experimental groups and 312 in the control groups from eight RCTs were included. PNS showed no significant effect on pain intensity, while analgesic consumption was marginally significantly reduced in the experimental group. Furthermore, no significant differences were observed regarding functional improvements in ROM or LOH after the intervention. Although PNS had no significant effect on pain relief or functional improvements, the intervention exhibited a marginally significant reduction in analgesic consumption. Future trials should be conducted with larger sample sizes, longer follow-up periods, and more varied stimulation parameters.
"Support the strong" or "Help the weak?": The effects of social comparison and social distance on cooperative behavior in the dictator game
Within an object-interdependent context, we conducted three experiments to investigate the influence of social comparisons on cooperative behavior, as well as to assess the mediating and moderating effects of related variables. In Experiment 1 (n = 207), we examined whether social comparisons impact cooperative behavior toward a comparator in a dictator game task. Here, we specifically focused on the mediating effects of evaluation of others' competence, along with three other potential mediators: self-competence evaluation, positive emotions, and negative emotions. Following the insights gained from Experiment 1, we proceeded to Experiments 2 (n = 279) and 3 (n = 298) to further explore whether social distance moderates the mediating effect of evaluation of others' competence. The results of all three experiments consistently indicated that upward (vs. non-) comparison facilitated cooperative behavior, whereas downward (vs. non-) comparison hindered it. Furthermore, our findings revealed that evaluation of others' competence served as a mediator between social comparison and cooperative behavior when the comparator (i.e., the cooperative partner) was perceived as being at a far-distance, whereas the mediating effect of evaluation of others' competence disappeared when social distance was close. These results reveal the pivotal role of evaluating others' competence and social distance in social interactions from the perspective of social comparison, which provides insights into how to promote cooperative behavior.
Does a stronger moral identity lead to a more reserved sense of humor? The influence of moral identity on sense of humor and its underlying psychological mechanisms
Three studies were conducted to examine the influence of moral identity on sense of humor, employing the benign violation theory (BVT) as a theoretical framework. Study 1 (n = 350), a questionnaire-based survey, aimed to establish a preliminary exploration of the relationship between moral identity and sense of humor. Studies 2 (n = 172) and 3 (n = 172) jointly examined the impact of activated moral identity on sense of humor (humor appreciation, humor sharing) through the recollection and writing task. The results of these studies indicated that the effects of (activated) moral identity on the sense of humor (humor appreciation, humor sharing) were moderated by the type of humor and social distance of the target. On the one hand, high levels of (or activated) moral identity can significantly and positively predict sense of humor (humor appreciation, sharing); on the other hand, when there is a moral violation in the humor, and the target involved is at a close social distance, activated moral identity decreases the humor appreciation and humor sharing, where benign judgment plays a mediating role. These findings enrich the understanding of the complex relationship between moral identity and sense of humor, and have significant theoretical and practical implications.
The relationship between openness to experience and humor production: Exploring the mediating roles of cognitive flexibility and ambiguity tolerance
The purpose of this study was to examine how individual openness to experience influences humor production and to explore the underlying psychological mechanisms of this relationship, specifically focusing on cognitive flexibility (the cognitive path) and ambiguity tolerance (the motivational path). To comprehensively evaluate individuals' humor production ability, Study 1 employed a subjective self-report questionnaire on sense of humor, while Study 2 used an objective humor dialogue generation task. The results of Study 1 indicated that openness to experience did not directly impact sense of humor; instead, the relationship between openness to experience and sense of humor was fully mediated by cognitive flexibility. In Study 2, findings showed that openness to experience positively predicted humor production ability, with ambiguity tolerance partially mediating this effect. These results suggest that individuals with higher levels of openness to experience have a greater capacity for generating humorous perspectives. Moreover, the study identified two psychological pathways-cognition and motivation-in the process of generating funny ideas. The specific pathway influenced by the measurement method used for humor production further highlights the importance of both cognitive flexibility and ambiguity tolerance in understanding how openness to experience contributes to humor production.
Psychological capacity profiles of different age groups and gender in a national representative sample
Beyond the specific cognitive capacities like numerical or verbal intelligence and cognitive speed, the so-called soft skills, namely, psychological capacities, have become highly important in modern life. This is the first representative study on the distribution of work-relevant psychological capacities in the general population. We investigate capacities in different age groups, gender, and their relation with basic sociodemographics. A representative sample of 2531 people aged 14-95 years was investigated concerning work-relevant psychological capacities with the mini self-rating for psychological activities and participation (Mini-ICF-APP-S). The strongest capacities in young people were mobility, flexibility, proactivity, contact to thirds, and group interaction. Other capacities were stronger in midlife (30-59 years), such as adjustment to rules and routines, planning and structuring, decision making and judgement, application of competence and knowledge, assertiveness, dyadic relationships, endurance, and self-care. Women reported better dyadic relationship capacities, and men felt more assertive. The study provides, for the first time, representative data on a broad range of psychological capacities according to an internationally validated capacity concept. Good psychological capacities occur not primarily in youth, but especially in midlife and older age. Regarding demographic change, this implies older people are highly competent in the working world.
Enhancement of joint flanker effect in intergroup competition
Representing the mental state of the partner lays the foundation for successful social interaction. While the representation of group members has been extensively studied, it is unclear how intergroup interactions affect it. In three experiments utilizing the joint flanker task, we found that competition between groups brought about a greater joint flanker effect (Experiment 1). Such phenomenon was not due to competition per se, as competition that occurred between individuals from different groups did not enhance the joint flanker effect (Experiment 2). Using the minimal grouping method to directly manipulate group entitativity, we found that the joint flanker effect was larger when participants perceived the group as being more closely connected; conversely, when they perceived the group as less close, the joint flanker effect was attenuated (Experiment 3). These results suggested that beliefs about the group may be key to how group competition enhanced the joint flanker effect. The potential cognitive mechanisms producing this phenomenon are fully discussed. Overall, our study is the first to explore the impact of intergroup interactions on the joint flanker effect and provides a new perspective on understanding the relationship between within-group representations and intergroup interactions.
Two masked prime arrows simultaneously affect a response to a target: Revealing of an additive unconscious priming effect
Since there are many sources of unconscious information in our minds, there is a possibility that multiple channels of unconscious information can affect a response at the same time. However, this question has been largely ignored by researchers. In the present study, we presented two opposite pointing arrows as the masked primes followed by a target arrow. The results suggested that the two directions in which the two prime arrows are pointing influenced the response to the target simultaneously and additively, that is, the overall priming effect caused by the two opposite pointing prime arrows was equal to the net effect of the individual congruent effect elicited by the same pointing prime arrow and the individual incongruent priming effect induced by the prime arrow poitning in the opposite direction. In addition, in Experiment 1, a biased delayed response to the target was observed when the target arrow and the opposite pointing prime arrow were closely positioned in space due to Gestalt continuity and closure grouping. According to these results, the "independent unconscious influence" and "reverse unconscious selection" hypotheses are proposed.
