Behaviour on even simple experimental games shows considerable individual differences, but previous attempts to link these preferences to stable personality traits have had mixed results. Here we address three limitations of earlier studies, namely: (1) uncertainties concerning the reliability of preferences; (2) use of personality instruments with limited cross-study comparability; and (3) confounds where more than one psychological motive can lead to a particular choice. Sixty-seven participants completed 12 distinct real-money games twice over a two-week interval along with 6 measures concerning their expectations about other players’ choices. Personality was measured using the full NEO-PI-R. Choices were highly stable across time (r = .84). Moreover, choices on the 12 games and 6 expectations reflected a single underlying dimension of “prosocial orientation”, measuring concern for the payoffs received by other players. Scores on the prosocial orientation dimension were related to personality, with openness, (low) neuroticism, and (low) extraversion retained as significant predictors.  相似文献

Social interaction requires the ability to infer another person’s mental state (Theory of Mind, ToM) and also executive functions. This fMRI study aimed to identify the cerebral correlates activated by ToM during a specific social interaction, the human-human competition. In this framework, we tested a conflict resolution task (Stroop) adapted to a virtual situation of competition. The participants were instructed to play in order to win either against a human-like competitor (human-human competition) or against a non-human competitor (human-machine competition). Only the human-human competition requires ToM as this type of competition is performed under social interaction. We identified first the classical network of executive regions activated by Stroop. Secondly, we identified the social (human-human) competition regions, represented by the bilateral superior and inferior frontal gyri, the anterior cingulate, the insula, the superior and anterior temporal, the hippocampus, the fusiform gyrus, the cuneus and the precuneus. Finally, we identified the executive regions that were modulated by the human-human competition, i.e., the executive control regions additionally activated when mentalizing in the context of social competition. They constituted a network predominant to the right and composed of the superior and middle frontal, anterior cingulate, insula and fusiform gyrus. We suggest that our experimental paradigm may be useful in exploration of the cerebral correlates of social adjustments in several situations such as psychiatric disorders presenting executive and social dysfunctions.  相似文献

This study has sought to explore whether there are at least two subtypes of anhedonia in schizophrenia: one closely linked with depression and another that occurs in the absence of depression which is related to a general paucity of internal experience. Participants were 163 adults with schizophrenia who completed assessments of depression, anhedonia, executive functioning, positive and negative symptoms, social cognition and metacognition. A cluster analysis based on participants’ depression and anhedonia symptom scores produced three groups: High Depression/High Anhedonia (n = 52), Low Depression/Low Anhedonia (n = 52), and Low Depression/High Anhedonia (n = 59). An ANCOVA and post hoc comparisons controlling for positive and negative symptoms found that the Low Depression/High Anhedonia group had poorer metacognition and social cognition than other groups. These findings point to the possibility of a subtype of anhedonia in schizophrenia, one occurring in the relative lesser levels of depression, and tied to deficits in the ability to think about oneself and others.  相似文献

The use of idealized advertising models has been heavily criticized in recent years. Existing research typically adopts a social comparison framework and shows that upward comparisons with models can lower self-esteem and affect, as well as produce maladaptive behavior. However, the alternative possibility that consumers can cope with threatening advertising models by excelling in other behavioral domains has not been examined. The present research draws on fluid compensation theory (Tesser, 2000) and shows that idealized models motivate improved performance in consumer domains that fall outside that of the original comparison. These more positive coping effects operate through self-discrepancies induced by idealized models, rather than self-esteem or negative affect. Specifically, self-discrepancies motivate consumers to improve decision-making by: 1) making more optimal choices from well-specified consideration sets, and 2) better self-regulating indulgent choices. More broadly, the current research integrates and extends theories of fluid compensation and self-discrepancy, as well as provides a more complete picture of the ways in which consumers cope with idealized advertising models.  相似文献

IntroductionStudies have shown the importance of psychosocial risks for physical and mental health particularly in the medical sector and among hospital workers.ObjectiveThe main goal of our study is to measure the magnitude of the six dimensions of the psychosocial work environment in a French hospital. The second goal is to highlight from the six dimensions, which are the most important ones for the hospital workers in order to propose specific actions of improvement of the well-being at work and prevention of social risks.MethodOur sample is composed of 1139 hospital workers. (1) A 24-item scale was created, based on the six dimensions identified by the DARES study. This scale allows measuring the degree of psychosocial risk and of well-being at work. (2) Social representations are measured by a free association task based on the target expression: well-being at work in the hospital. (3) Participants also answered an open-ended question, on how to improve well-being at work in the hospital; answers were analyzed by a hierarchical classification.ResultsFour of the six dimensions extracted from the factorial analysis are equal to those identified by the DARES’ report: Work demand, Emotional demands, Relationships at work and Job insecurity. Quantitative analyses show that, for hospital workers, the level of risk is the highest on the first two. The social representation of well-being at work in the hospital, and the discourse analysis indicate that the dimension which is the most important for the hospital workers is Relationships at work.ConclusionIn this study, the use of both quantitative and qualitative assessments allows having some elements to analyze the quality of working conditions in the hospital. Moreover, reducing the level of psychosocial risk has a positive effect on workers’ satisfaction, well-being and health.  相似文献

For our research on “Gender practices and violence between peers: the stakes of mixed education” (ANR-09-ENFT-006), two researchers observed interactions between students within five schools during the 2011–2012 school year in an large French city. This paper focuses on the challenges of ethnography, the validity of the results produced by such a methodology, and the opportunity to intersect clinical (notably transference and counter-transference) and socio-anthropological concepts. Our analyses center on questions related to social class and the sex-gender system.  相似文献

ObjectivesSocial Cognitive Theory (SCT) has often been used as a guide to predict and modify physical activity (PA) behavior. We assessed the ability of commonly investigated SCT variables and perceived school environment variables to predict PA among elementary students. We also examined differences in influences between Hispanic and non-Hispanic students.DesignThis analysis used baseline data collected from eight schools who participated in a four-year study of a combined school-day curriculum and environmental intervention.MethodsData were collected from 393 students. A 3-step linear regression was used to measure associations between PA level, SCT variables (self-efficacy, social support, enjoyment), and perceived environment variables (schoolyard structures, condition, equipment/supervision). Logistic regression assessed associations between variables and whether students met PA recommendations.ResultsSchool and sex explained 6% of the moderate-to-vigorous PA models' variation. SCT variables explained an additional 15% of the models' variation, with much of the model's predictive ability coming from self-efficacy and social support. Sex was more strongly associated with PA level among Hispanic students, while self-efficacy was more strongly associated among non-Hispanic students. Perceived environment variables contributed little to the models.ConclusionsOur findings add to the literature on the influences of PA among elementary-aged students. The differences seen in the influence of sex and self-efficacy among non-Hispanic and Hispanic students suggests these are areas where PA interventions could be tailored to improve efficacy. Additional research is needed to understand if different measures of perceived environment or perceptions at different ages may better predict PA.  相似文献

What motivates people to consume and engage with food media on social networks? We adopt an evolutionary lens to suggest that the valence of people’s affective state varies by the implied caloric density of food media, which has a direct impact on social media engagement. First, we analyze a catalog of Buzzfeed’s Tasty videos based on nutritional content derived from the dish’s ingredients and find that visualizing caloric density (i.e., calories per serving) positively influences likes, comments, and shares on Facebook. We then replicate this phenomenon in an experiment, providing preliminary evidence for the role of affect as an explanatory mechanism. We conclude by isolating the role of affect with a classic misattribution task, which attenuates the elevated engagement resulting from exposure to calorie-dense food media. These findings contribute to the dialogue on the antecedents of social media engagement and offer implications for content developers, advertisers, consumer health advocates, and policymakers.  相似文献

Understanding the malleable factors that underpin people’s ongoing commitment to specific forms of exercise is crucial to facilitate more effective efforts to improve participation rates. To this end, we examined the role of (a) perceiving the members of one’s exercise class to be similar to each other on various dimensions, and (b) possessing a strong social identity as an exercise class member in shaping one’s future participation in that class. During a 3-week intensive sampling period, 779 unique responses were obtained from 278 attendees (who were invited to complete a questionnaire on each occasion they attended an exercise class). On each questionnaire, participants indicated their perceptions of class members’ similarity and their own social identification in relation to the exercise class they had just participated in. Participation was conceptualised as attendance at the same class (i.e., same time and type) the following week and was measured objectively using the fitness facility’s electronic class attendance records. Linear multilevel models showed that participants identified more strongly as members of exercise classes in which they perceived that their fellow attendees were similar to each other: both in general, and in terms of age, physical fitness, and their attitude towards the class. Participants also tended to be more likely to attend a given exercise class the following week to the extent that they reported a strong sense of social identification as a member of that class. These relationships were replicated in a multilevel mediation model, which revealed a significant indirect effect of similarity on class attendance through social identification. Results point to the role that social identification can play in promoting repeated exercise participation and indicate that one way to facilitate exercisers’ greater social identification might be to purposefully create exercise classes and groups comprised of relatively homogenous individuals.  相似文献

Grounded in social cognitive theory (SCT), this study sought to examine whether parents perceived social cognitive factors regarding children's physical activity (PA) behaviors were associated with preschool children's moderate-to-vigorous PA (MVPA) levels. A total of 142 Hong Kong parent-child pairs from five preschools/childcare centers completed all assessments in the cross-sectional study. Children’s (42% girls; mean age = 4.52 ± 0.67 years) PA was measured through accelerometers. Parents (74% mothers; mean age = 37.38 ± 4.63 years) completed a paper-based questionnaire assessing the social cognitive factors on their children’s PA participation. The data were analyzed using latent variable structural equation modeling. Findings revealed that the model showed acceptable fit with the data: χ2 (23) = 38.14, p = .025, χ2/df = 1.66, CFI = 0.955, TLI = 0.929, RMSEA = 0.068, 90% CI [0.025, 0.106], and SRMR = 0.072. The model accounted for 39.1% of the variance in the PA behavior of preschool-aged children. Structural equation modelling revealed parental self-efficacy (β = 0.29, 95% CI [0.95, 0.49]) and goal setting (β = 0.25, 95% CI [0.06, 0.44]) were directly associated with children’s MVPA. Outcome expectations (β = 0.09, 95% CI [0.01, 0.03]) and goal setting (β = 0.18, 95% CI [0.05, 0.32]) mediated the association between parental self-efficacy and children’s MVPA. Indirect associations of parental self-efficacy from setting goals via parental support (β = 0.15, 95%CI [0.02, 0.30]) and perceived barriers (β = 0.15, 95% CI [0.05, 0.28]) were uncovered. Results supported the use of SCT in understanding how the parents perceived social cognitive factors predict the PA behaviors of young children. This study provides insight into whether these theoretical variables could be modified or promoted in future intervention programs. Enhancing parents’ abilities to ensure preschool-aged children are physically active is of great importance given the global decline in PA among children.  相似文献
