Kraut and Johnston (1979) found surprisingly few smiles in large samples of bowlers and hockey fans during happy events--unless they were simultaneously engaged in social interaction. A limitation of their studies is that there was no direct test of subjects' actual emotional experience at the moments in which they were observed. This article reports two field studies in which emotions were reported by bowlers and by soccer fans. Analysing facial behaviour of those who reported happiness, we found a low probability of smiling in the absence of social interaction (.09 for bowlers and .07 for soccer fans) and a high probability of smiling during social interaction (.78 and .70). These findings question the common assumption that smiles are an indicator of happiness per se, and support the alternative hypothesis of a more complex and indirect relationship between smiling and happiness.  相似文献

The objective of this study was to investigate personality correlates of set‐shifting behaviour using a task sensitive to dopaminergic activity. As expected, set‐shifting behaviour was positively correlated with scores on the Sensitivity to Reward scale, a measure of Gray's impulsivity. Discussion is focused on the relationship between this greater ability for set‐shifting and the proneness to disinhibition.  相似文献

Resilience, the ability to bounce back from difficult events, is critical for an individual to negotiate stressors and adversity. Despite being widely studied, little is known about the processes involved in the development of resilience. The goal of the studies are to investigate the relationship between motivation orientation, emotional intelligence, cognitive appraisals, and psychological resilience. Two studies, using self-report questionnaires were conducted with employed young adults also enrolled in post-secondary studies (pre- and during the pandemic) to test the tenability of our proposed models. Study 1 and Study 2 showed that emotional intelligence and challenge appraisals were mediators of autonomous motivation and resilience. Study 2 revealed statistically significant differences in mean scores of autonomous motivation and emotional intelligence between non-pandemic students and pandemic students. Based on the findings, it is suggested that autonomous motivation, emotional intelligence, and challenge appraisals are important aptitudes for the development of resilience. Furthermore, findings suggest that social isolation caused by the pandemic may have affected levels of emotional intelligence. Ultimately, the research expands the literature on both self-determination theory and resilience by offering a unique multiple mediation model for predicting the development of resilience within the employed undergraduate population.  相似文献

The current study explored the influence of different levels of speaker coherence on rule following and speaker preference. In Experiment 1, rules provided by three different speakers were either 100% accurate, 0% accurate, or 50% accurate/inaccurate. Experiment 2 was similar to Experiment 1 except that the speaker's coherence was adjusted to 80% accurate, 20% accurate, and 50% accurate/inaccurate, respectively. Overall, participants tended to follow coherent speaker rules and avoid following incoherent speaker rules during training and testing phases. The results also indicated that following and not following rules provided by speakers may be generalizable to novel stimuli and maintained in the absence of differential reinforcement (i.e., in experimental test phases). Additionally, in a preference test, participants tended to prefer coherent over incoherent and partially coherent speakers. Furthermore, participants tended to prefer the relatively more incoherent speaker (i.e., 0% or 20% accurate) over the 50% accurate coherent speaker in both experiments. Finally, a comparison of the results of both experiments indicated that different levels of relational coherence affected the variability of rule-following and speaker preference behaviors. These findings are discussed in the context of the complexities that appear to be involved in rule-following behaviors and speaker preference.  相似文献
