To clarify the influence of disciplinary culture on the materialism–subjective well-being (SWB) relationship, as well as the relationship between changes in materialism and changes in SWB, the current longitudinal study tracked the levels of materialism and SWB among first-year undergraduates for 12 months. A total of 218 participants from a congruent disciplinary culture (i.e., business school) and 210 participants from an incongruent disciplinary culture (i.e., engineering school) provided ratings on the Material Values Scale, the Satisfaction with Life Scale, and the Positive and Negative Affect Schedule in three waves. The following results were obtained: (1) the interaction effect of disciplinary culture and time was significant. In Wave 3, the level of materialism in business school was significantly higher than that in engineering school, but this difference was not found in Waves 1 and 2; (2) the negative relationship between materialism and SWB remained stable over time and was not moderated by disciplinary culture. Moreover, disciplinary culture did not moderate the relationship between changes in materialism and changes in SWB. The above findings indicate that disciplinary culture influences the development of materialism but not the materialism–SWB relationship in the long term.  相似文献

Male–male vocal competition in anuran species is critical for mating success; however, it is also highly time-consuming, energetically demanding and likely to increase predation risks. Thus, we hypothesized that changes in the social context would cause male vocal competition to change in real time in order to minimize the costs and maximize the benefits of competition. To test this hypothesis, we assessed the effect of repeating playbacks of either white noise (WN) or male advertisement calls on male call production in the Emei music frog (Babina daunchina), a species in which males build mud-retuse burrows and call from within these nests. Previous studies have shown that calls produced from inside burrows are highly sexually attractive (HSA) to females while those produced outside nests are of low sexual attractiveness (LSA). Results showed that most subjects called responsively after the end of WN playbacks but before the onset of conspecific call stimuli although call numbers were similar, indicating that while males adjusted competitive patterns according to the biological significance of signals, their competitive motivation did not change. Furthermore, these data indicate that the frogs had evolved the ability of interval timing. Moreover, when the inter-stimulus interval (ISI) between playbacks was varied, the subjects preferentially competed with HSA calls when the ISI was short (<4 s) but responded equally to HSA and LSA calls if the ISI was long (≥4 s), suggesting that males allocate competitive efforts depending on both the perceived sexual attractiveness of rivals and the time available for calling. Notably, approximately two-thirds of male calls occurred in response to HSA calls, a preference rate comparable to that previously found for females in phonotaxis experiments and consistent with the idea that the mechanisms underlying both the male’s competitive responses to rivals and the female’s preferences toward potential mates coevolved under the same selective pressure.  相似文献

Rejection sensitivity (RS) can be defined as the disposition that one tends to anxiously expect, readily perceive, and intensely react to rejection. High-RS individuals are more likely to suffer mental disorders. Previous studies have investigated brain activity during social rejection using different kinds of rejection paradigms and have provided neural evidence of individual differences in response to rejection cues, but the association between individual differences in RS and brain structure has never been investigated. In this study, voxel-based morphometry (VBM) was used to investigate the relationship between gray matter volume (GMV) and RS in a large healthy sample of 150 men and 188 women. The participants completed the RS Questionnaire and underwent an anatomical magnetic resonance imaging scan. Multiple regression was used to analyze the correlation between regional GMV and RS scores, adjusting for age, sex, and total brain GMV. These results showed that GMV in the region of the posterior cingulate cortex/precuneus was negatively associated with RS, and GMV in the region of the inferior temporal gyrus was positively correlated with RS. These findings suggest a relationship between individual differences in RS and GMV in brain regions that are primarily related to social cognition.  相似文献

The primary purposes of this study were to (1) compare the characteristics of childhood experiences of parental rearing patterns in China reported by patients with borderline personality disorder (BPD), patients with other personality disorders and patients without personality disorders; (2) identify the reported parental rearing patterns associated with BPD in China; and (3) determine whether these patterns differ for males and females. One hundred and fifty‐two patients with BPD, 79 patients with other personality disorders and 55 patients without Axis II diagnoses were administered the Chinese version of the McLean Screening Instrument for BPD and completed the Egna Minnen av Barndoms Uppfostran (EMBU), a self‐report measure of childhood parental rearing patterns. Parental rearing patterns reported by the BPD group were characterized by less emotional warmth, and greater punishment, rejection and control than patterns reported by the other two groups. Within the BPD group, males were more likely than females to report parental punishment, rejection and control. Paternal punishment, low maternal emotional warmth and female gender predicted BPD diagnosis. Negative parental rearing patterns appear to contribute to the development of BPD in China and vary with the gender of the child. Maternal emotional warmth may be a protective factor against BPD.  相似文献

Clinicians commonly incorporate adolescents’ self-reported suicidal ideation into formulations regarding adolescents’ risk for suicide. Data are limited, however, regarding the extent to which adolescent boys’ and girls’ reports of suicidal ideation have clinically significant predictive validity in terms of subsequent suicidal behavior. This study examined psychiatrically hospitalized adolescent boys’ and girls’ self-reported suicidal ideation as a predictor of suicide attempts during the first year following hospitalization. A total of 354 adolescents (97 boys; 257 girls; ages 13–17 years) hospitalized for acute suicide risk were evaluated at the time of hospitalization as well as 3, 6, and 12 months later. Study measures included the Suicidal Ideation Questionnaire-Junior, Multidimensional Anxiety Scale for Children, Children’s Depression Rating Scale-Revised, Beck Hopelessness Scale, Youth Self-Report, and Personal Experiences Screen Questionnaire. The main study outcome was presence and number of suicide attempt(s) in the year after hospitalization, measured by the Diagnostic Interview Schedule for Children. Results indicated a significant interaction between suicidal ideation, assessed during first week of hospitalization, and gender for the prediction of subsequent suicide attempts. Suicidal ideation was a significant predictor of subsequent suicide attempts for girls, but not boys. Baseline history of multiple suicide attempts was a significant predictor of subsequent suicide attempts across genders. Results support the importance of empirically validating suicide risk assessment strategies separately for adolescent boys and girls. Among adolescent boys who have been hospitalized due to acute suicide risk, low levels of self-reported suicidal ideation may not be indicative of low risk for suicidal behavior following hospitalization.  相似文献

Extensive evidence has been obtained that supports an association between an attentional bias (AB) toward negative stimuli and vulnerability to stress-related psychopathology, little is known regarding the characteristics of individual AB in different posttraumatic growth (PTG) levels. The current study used a modified dot-probe task to investigate if individual differences in AB towards either positive or negative emotional stimuli, are related to self-reported PTG. A sample of 202 patients completed the experiment. Patients with low levels of PTG did not exhibit AB toward negative or positive stimuli, patients with medium levels of PTG had difficulty disengaging attention from negative stimuli, patients with high levels of PTG had difficulty disengaging attention from positive stimuli. And the AB towards positive stimuli was only predictive for PTG. An implication of this finding is that there are different characteristics of implicit cognitive processing in patients with different levels of PTG, suggesting the necessity of psychological intervention on the accidentally injured patients.  相似文献

Based on self‐determination theory, the current research aimed to explore the potential mediating effect of relatedness need satisfaction on the relationship between charitable behavior and well‐being in the Chinese context. Employing a cross‐sectional design, participants reported data on the aforementioned variables in Study 1. The results indicated that relatedness need satisfaction mediated the positive relationship between charitable behavior and hedonic well‐being and that between charitable behavior and eudaimonic well‐being. Subsequently, a field experiment was conducted in Study 2. Participants rated their levels of relatedness need satisfaction and well‐being after charitable donation behaviors were primed. We again observed consistent results. Specifically, charitable behavior was positively associated with both hedonic and eudaimonic well‐being, and these relationships were mediated by relatedness need satisfaction. The above findings help to clarify the association between charitable behavior and people's subjective feelings (i.e., well‐being), and they deepen our understanding of the underlying mechanism from the perspective of psychological needs satisfaction.  相似文献

Empirical research on both meaningful work and organizational commitment has been criticized because research in both fields is largely unsystematic. By integrating the cognitive appraisal theory and identity theory into the meaningful work and affective commitment literatures, we examined the mediating role of positive work reflection (study 1 and study 2) and the moderating role of work centrality (study 2) in the relation between meaningful work and affective commitment. We conducted two independent studies with two-wave data to examine our hypotheses through mediation and moderated mediation bootstrapping procedures. Both study 1 and study 2 found that positive work reflection mediated the relationship between meaningful work and affective commitment. In addition, study 2 revealed that the positive relationship between meaningful work and affective commitment was stronger for those who place less importance on work (i.e., low work centrality). The meaningful nature of one’s work may motivate those who view work as peripheral to recall positive moments of their work, which, in turn, impacts their affective commitment to the organization. Thus, in order to increase affective commitment, promoting meaningful work might be particularly important for those with low work centrality. This is one of the first studies to examine positive work reflection as a cognitive pathway linking meaningful work to affective commitment and identify a boundary condition where meaningful work may not be associated with affective commitment for those who are high in work centrality.  相似文献
