Emotion regulation may influence psychological responses to exercise. We examined whether the emotion regulation strategies, cognitive reappraisal and distraction, influenced psychological state and prefrontal cortex oxygenation during endurance exercise. Twenty-four endurance runners ran for 90 min at 75–85% maximum heart rate in three separate sessions with no instruction or with instructions to use cognitive reappraisal or distraction. Participants rated their emotional arousal, emotional valence, and perceived exertion before, every 30 min during, and after exercise. Functional near-infrared spectroscopy quantified changes in prefrontal cortex oxygenation. Participants felt lower emotional arousal and physical exertion when instructed to utilize cognitive reappraisal than when given no emotion regulation instruction. Such responses to distraction did not differ from the other conditions. Emotion regulation strategies did not influence emotional valence or prefrontal cortex oxygenation. Participants’ analytical interpretation of the cognitive reappraisal instruction could contribute to small effect sizes and limited effects. Further research should determine contexts under which emotion regulation strategies most benefit endurance exercise experience.  相似文献

Even with the recent surge of research on achievement emotions, few studies have investigated emotions in feedback situations and the appraisals associated with such emotions. The purpose of this study was to examine emotion appraisals of constructive criticism, negative, and positive feedback, to aid us in determining whether these appraisals differed by feedback type. In a task asking them to provide open-ended responses as they imagined receiving feedback on a writing task, undergraduates (N?=?270) gave reasons for why they might experience unpleasant emotions from positive feedback and pleasant emotions from negative feedback along with reasons for both pleasant and unpleasant emotions emanating from constructive feedback. Open coding of responses yielded categories for each emotion-feedback pairing that, across all emotions, were collapsed into five appraisal categories: feedback suggests ways to improve, a mismatch between feedback and task exists, feedback targets the self or one’s ability, feedback says something about the relationship between feedback giver and receiver, and the task is judged for its value. Distributions of appraisal categories distinguished constructive feedback from positive and negative feedback. Implications are drawn for control-value theory and for classroom feedback practices.  相似文献

Differences in the processing of emotions like fear and sadness have important implications for our understanding of many psychological phenomena (e.g., attentional biases, psychopathology). The late positive potential (LPP) is an established event-related potential that reflects motivated attention to emotional stimuli at the neural level with excellent temporal resolution, but has been infrequently used to study differences across emotions. Drawing on functional theories of emotion suggesting that the quick processing of fear-inducing stimuli increases chances of survival, we hypothesized that fear-inducing pictures would produce larger LPP amplitudes compared to other emotions (happy and sad) in the early time windows of the LPP (e.g., 400–700, 700–1000 ms). The results supported our hypothesis, offering new, albeit preliminary, evidence of the differential processing of threat-related stimuli on the LPP.  相似文献

Ostracism is known to cause psychological distress; however, it remains unclear why ostracism evokes this response. Two experiments tested empirically whether fear of death mediates ostracism distress (mood) and whether marital status moderates this role. A total of 345 participants played Cyberball with two other ostensible players. After the game, accessibility of death-related thoughts was assessed by a word completion task, and a mood questionnaire was used to measure their distress. Death thoughts fully mediated ostracism distress. Marital status moderated this mediation effect in that no moderation was observed in married participants, suggesting that marriage may buffer death anxiety. The discussion centers on the ways in which these findings contribute to the ostracism and terror management literature by providing empirical evidence that death thoughts mediate ostracism distress, and the moderating effects of marriage on this mediation effect.  相似文献

Fear of missing out, known colloquially as FOMO, appears to be a common experience, and has recently become part of the vernacular, receiving frequent mentions in the popular media. The present paper provides a multi-method empirical examination of FOMO. In a first study, experience sampling was used to assess FOMO experiences among college freshmen. Nightly diaries and end-of-semester measures provided data on the short and long-term consequences of experiencing FOMO. Results showed that students experience FOMO frequently, particularly later in the day and later in the week, and while doing a required task like studying or working. More frequent experiences of FOMO were associated with negative outcomes both daily and over the course of the semester, including increasing negative affect, fatigue, stress, physical symptoms, and decreased sleep. A second experimental study investigated FOMO on a conceptual level, distinguishing FOMO from general self-regulation and exploring its links with social media.  相似文献

It is argued that truth value of a sentence containing free variables in a context of use (or the truth value of the proposition it expresses in a context of use), just as the reference of the free variables concerned, depends on the assumptions and posits given by the context. However, context may under-determine the reference of a free variable and the truth value of sentences in which it occurs. It is argued that in such cases a free variable has indeterminate reference and a sentence in which it occurs may have indeterminate truth value. On letting, say, x be such that \(x^2=4\), the sentence ‘Either \(x=2\) or \(x=-2\)’ is true but the sentence ‘\(x=2\)’ has an indeterminate truth value: it is determinate that the variable x refers to either 2 or \(-2\), but it is indeterminate which of the two it refers to, as a result ‘\(x=2\)’ has a truth value but its truth value is indeterminate. The semantic indeterminacy is analysed in a ‘radically’ supervaluational (or plurivaluational) semantic framework closely analogous to the treatment of vagueness in McGee and McLaughlin (South J Philos 33:203–251, 1994, Linguist Philos 27:123–136, 2004) and Smith (Vagueness and degrees of truth, Oxford University Press, Oxford, 2008), which saves bivalence, the T-schema and the truth-functional analysis of the boolean connectives. It is shown that on such an analysis the modality ‘determinately’ is quite clearly not an epistemic modality, avoiding a potential objection raised by Williamson (Vagueness, Routledge, London, 1994) against such ‘radically’ supervaluational treatments of vagueness, and that determinate truth (rather than truth simpliciter) is the semantic value preserved in classically valid arguments. The analysis is contrasted with the epistemicist proposal of Breckenridge and Magidor (Philos Stud 158:377–400, 2012) which implies that (in the given context) ‘\(x=2\)’ has a determinate but unknowable truth value.  相似文献

How we define the space of possibilities of dispositional essentialism (DE)—that is, the set of possible worlds that are genuinely possible from the point of view of DE—has important consequences for central modal debates such as how to understand the concept of essence or the relation between DE and the necessity of laws of nature. In order to define DE’s space of possibilities we need to explore DE’s consequences regarding both necessity and possibility. Unfortunately, the notion of possibility has not received much attention within the DE literature. In this paper, I attempt to fill this gap. I argue that the standard way of understanding possibility found in the literature—a proposition is possible iff it expresses the manifestation of some actual disposition—needlessly restricts the space of possibilities by not accepting global and absolute possibilities, including some alien properties, as genuinely possible. I propose instead to accept a more permissive understanding of possibility: a proposition is possible iff it does not contradict any of the necessities that follow from the core commitments of DE. This allows dispositionalists to expand their modal space and to account for modal intuitions that may otherwise undermine the tenability of DE.  相似文献

Do states have a right to exclude prospective immigrants as they see fit? According to statists the answer is a qualified yes. For these authors, self-determining political communities have a prima facie right to exclude, which can be overridden by the claims of vulnerable groups such as refugees and children born in the state’s territory. However, there is a concern in the literature that statists have not yet developed a theory that can protect children born in the territory from being excluded from the political community. For if the self-determining political community has the right to decide who should form the self in the first place, then that right should count against both newcomers by immigration and newcomers by birth. Or so the concern goes. In this essay, I defend statism against this line of criticism and provide a liberal justification for the inclusion of children born within the state’s borders. My account leads to some surprising implication for citizenship law, as well as immigration arrangements in the area of asylum and unauthorized immigration.  相似文献

Recent years have seen considerable attention paid to the methodology of philosophy. The puzzle is simple—if philosophy is not an empirical discipline, how can one philosophical theory be rationally preferred over another? One answer to this question is that we should apply the theoretical virtues. Foremost among these theoretical virtues is simplicity—so perhaps we should prefer simpler philosophical theories to more complex ones. Huemer (Philos Q 59:216–236, 2009) objects that the reasons to prefer simpler theories in science do not apply in philosophy. I will argue that Huemer is mistaken—the arguments he marshals for preferring simpler theories in science can also be applied in philosophy. Like Huemer, I will focus on the philosophy of mind and the nominalism/Platonism debate. But I want to engage with the broader issue of whether simplicity is relevant to philosophy.  相似文献

Intuitively, one who counts a morally bad person as a friend has gone wrong somewhere. But it is far from obvious where exactly they have gone astray. Perhaps in cultivating a friendship with a bad person, one extends to them certain goods that they do not deserve. Or perhaps the failure lies elsewhere; one may be an abettor to moral transgressions. Yet another option is to identify the mistake as a species of imprudence—one may take on great personal risk in counting a bad person as a friend. In this paper, I argue that none of these intuitive explanations are entirely convincing; for many such proposals run contrary to widely accepted features of friendship. However, they do point us in the direction of a more satisfying explanation—one which concerns a person’s moral priorities. An individual who counts a morally bad person as a friend is, I propose, one who betrays a distinct kind of defect in her values.  相似文献
