While the majority of studies have focused on dispositional mindfulness and the efficacy of mindfulness meditation, there has been limited study exploring the effect of state mindfulness on emotions and its potential mechanism. Therefore, we conducted an ambulatory assessment study to monitor state mindfulness and emotions in daily life and examine the mediating effect of rumination in a natural context. One hundred Chinese university students rated their state mindfulness, rumination, and emotions (e.g., anxiety, depression, happiness) five times per day for a week. Using hierarchical linear models, we and found that at the within‐person level, higher current state mindfulness was associated with more subsequent positive emotions and less subsequent negative emotions. Current rumination partially mediated the relation between current state mindfulness and subsequent positive emotions (happiness, relaxation, contentment, interest) and negative emotions (depression, anger, boredom, sadness). At the between‐person level, higher state mindfulness was associated with more positive emotions and less negative emotions. Individuals’ overall rumination partially mediated the relation between state mindfulness and emotions (depression, anger, boredom, sadness, relaxation). We concluded that higher state mindfulness was associated with lower rumination, which in turn resulted in more positive emotions and less negative emotions. More important, state mindfulness also exerted a dynamic impact on daily emotions via rumination.  相似文献

A better understanding of the impact of lifestyle factors on cognitive function in older adults is critical for developing intervention strategies to achieve successful aging. Moreover, older adults who fulfill the World Health Organization criteria for anemia have a significantly higher risk of developing dementia. In the current study, we aimed to assess the buffering effects of lifestyle on cognitive function in older Chinese adults through a nationally representative survey. The sample consisted of 1201 participants (mean age: 82.39 ± 12.08 years, 52.1% female) from the 2011/2012 and 2014 waves of the Chinese Longitudinal Healthy Longevity Survey. Multiple linear regression analyses were used to explore the relationship between changes in lifestyle factors and the rate of cognitive function changes, as well as the effects of the interaction between lifestyle factors and anemia on cognitive function changes. Increased levels of participation in leisure activities, social activities, and dietary diversity delayed cognitive decline. Persistent anemia accelerated cognitive decline, while frequent participation in leisure activities delayed cognitive decline due to anemia. The increased levels of participation in leisure activities, social activities, and dietary diversity can alleviate the cognitive decline caused by aging itself, and more frequently participation in leisure activities can also alleviate the adverse effects of anemia on cognitive function in older adults.  相似文献

To increase game loyalty but decrease game addiction, this study examines online game social migration and tests the mediating effects of offline social value and maladaptive cognition on the basis of the theory of consumption value and the cognitive behavioral model of pathological Internet use. The results are as follows: (i) Overall, online game social migration is associated with greater game loyalty and less game addiction; (ii) The positive association between online game social migration and game loyalty was mediated by offline social value; and (iii) Online game social migration is associated with lower game addiction. This paper provides a new perspective (taking into account both business interests and players' psychological health) for online game research and also offers practical guidance for cooperation between game companies and the public.

Aggression is one of the public social issues affecting campus harmony and stability, and social exclusion is an important interpersonal contextual factor among many factors affecting aggression. However, studies examining the influence of social exclusion on aggression and its mediating mechanism are not systematic enough. Based on the general aggression model (GAM), we intend to explore the role of hostile attribution bias (HAB) in both trait and state levels of social exclusion, which leads to aggression through a combination of questionnaire and experimental methods. Study 1 surveyed 388 current high school students (Mage = 16.09, SD = 1.01) and found that HAB mediates the relationship between long-term social exclusion (trait level) and aggression tendency. Study 2 experimented with 181 high school students (Mage = 16.95, SD = 1.13) to examine whether short-term social exclusion (state level) after initiating the Cyberball paradigm could still influence aggressive behavior through the mediating role of HAB. Results found that the mediating role of HAB still holds. The findings of the study further enrich the GAM and have important implications for a more targeted approach to aggression prevention and intervention.  相似文献

The speech register that adults especially caregivers use when interacting with infants and toddlers, that is, infant-directed speech (IDS) or baby talk, has been reported to facilitate language development throughout the early years. However, the neural mechanisms as well as why IDS results in such a developmental faciliatory effect remain to be investigated. The current study uses functional near-infrared spectroscopy (fNIRS) to evaluate two alternative hypotheses of such a facilitative effect, that IDS serves to enhance linguistic contrastiveness or to attract the child's attention. Behavioral and fNIRS data were acquired from twenty-seven Cantonese-learning toddlers 15–20 months of age when their parents spoke to them in either an IDS or adult-directed speech (ADS) register in a naturalistic task in which the child learned four disyllabic pseudowords. fNIRS results showed significantly greater neural responses to IDS than ADS register in the left dorsolateral prefrontal cortex (L-dlPFC), but opposite response patterns in the bilateral inferior frontal gyrus (IFG). The differences in fNIRS responses to IDS and to ADS in the L-dlPFC and the left parietal cortex (L-PC) showed significantly positive correlations with the differences in the behavioral word-learning performance of toddlers. The same fNIRS measures in the L-dlPFC and right PC (R-PC) of toddlers were significantly correlated with pitch range differences of parents between the two speech conditions. Together, our results suggest that the dynamic prosody in IDS increased toddlers’ attention through greater involvement of the left frontoparietal network that facilitated word learning, compared to ADS.  相似文献

Deficit in decision‐making has been found in patients with schizophrenia (SCZ), major depressive disorder (MDD), and bipolar disorder (BD), respectively, while the common and distinct characteristics of this deficit among these patients are still unclear. The present study aimed to make a transdiagnostic comparison of the affective decision‐making ability in patients with SCZ, MDD, and BD. In this study, 33 patients with SCZ, 23 patients with MDD, 29 patients with BD, and 34 healthy controls (HCs) were recruited and the Iowa Gambling Task (IGT) was used to assess the affective decision‐making ability. The results showed that all three diagnostic groups tended to select the disadvantageous decks but not advantageous decks compared to HCs. For patients with SCZ, an excessive preference for the disadvantageous decks with larger‐magnitude less frequent punishments (deck B) may be the main reason of the deficit in affective decision‐making, while that in patients with MDD was a significantly decreased ability to choose advantageous decks on the whole but with larger‐magnitude less frequent punishments (deck D). As regards patients with BD, the concurrence of more choices of deck B and fewer choices of deck D was the characteristic of the deficit in affective decision‐making. Our findings suggest a common affective decision‐making impairment in the context of multiple choices in patients with SCZ, MDD, and BD, while the underlying mechanisms of the impairment among these patients may be slightly different.  相似文献

Amotivational symptoms are observed in schizophrenia (SCZ), bipolar disorder (BD), and major depressive disorder (MDD). Effort–cost computation may be a potential contributor to amotivation transdiagnostically. This study examined effort–cost computation in these three diagnostic groups. This study recruited 141 outpatients (49 SCZ, 52 non‐psychotic BD, and 40 non‐psychotic MDD) and 57 healthy controls (HCs). We administered the Effort‐Expenditure for Reward Task (EEfRT), which manipulated different levels of reward magnitude and probability relating to a high and low physical effort task. There were significant interactions between group and reward magnitude, group and reward probability, and group and expected value on the percentage of high‐effort choices. SCZ, BD, and MDD patients made comparably fewer high‐effort choices than HCs in the high‐reward magnitude, high‐reward probability, and high‐expected‐value conditions. Self‐reported amotivation did not correlate with decision‐making on the EEfRT. Our findings suggest that reduced effort expenditure for reward is a transdiagnostic phenotype in SCZ, BD, and MDD.  相似文献

Studies have shown that numerosity‐based arithmetic training can promote arithmetic learning in typically developing children as well as children with developmental dyscalculia (DD), but the cognitive mechanism underlying this training effect remains unclear. The main aim of the current study was to examine the role of visual form perception in arithmetic improvement through an 8‐day numerosity training for DD children. Eighty DD children were selected from four Chinese primary schools. They were randomly divided into the intervention and control groups. The intervention group received training on an apple‐collecting game, whereas the control group received an English dictation task. Children's cognitive and arithmetic performances were assessed before and after training. The results showed that the intervention group showed a significant improvement in arithmetic performance, approximate number system (ANS) acuity, and visual form perception, but not in spatial processing and sentence comprehension. The control group showed no significant improvement in any cognitive ability. Mediation analysis further showed that training‐related improvement in arithmetic performance was fully mediated by the improvement in visual form perception. The results suggest that short‐term numerosity training enhances the arithmetic performance of DD children by improving their visual form perception.  相似文献

This research aimed to examine the effects of negative metastereotypes (i.e., patients believe that doctors have negative opinions about them) and conflict experience on doctor–patient relationships. A 2 × 2 experimental study was conducted on 84 outpatients who were randomly assigned to either a negative metastereotype activation (NMSA) condition or a nonnegative metastereotype activation (non‐NMSA) condition. Each group consisted of patients with and without conflict experience (CE). Intergroup anxiety and doctor–patient relationships were subsequently assessed. Results showed that NMSA and CE increased intergroup anxiety and undermined doctor–patient relationships. In addition, the interaction between NMSA and CE on doctor–patient relationships was significant. When negative metastereotypes were activated, patients with CE showed more unfavorable relationships with doctors as compared with those under non‐NMSA activation condition; no metastereotype effects on doctor–patient relationships were observed among patients without CE. These findings provided insights into an important predictor of doctor–patient relationships as well as its mechanism. Future studies should consider negative metastereotypes and CE to develop interventions for improving doctor–patient relationships.  相似文献
