According to flow theory, skill-demand balance is optimal for flow. Experimentally, balance has been tested only against strong overload and strong boredom. We assessed flow and enjoyment as distinct experiences and expected that they (a) are not optimized by constant balance, (b) experimentally dissociate, and (c) are supported by different personality traits. Beyond a constant balance condition (“balance”), we realized two dynamic pacing conditions where demands fluctuated through short breaks: one condition without overload (“dynamic medium”) and another with slight overload (“dynamic high”). Consistent with assumptions, constant balance was not optimal for flow (balance ≤ dynamic medium < dynamic high) and enjoyment (balance ≤ dynamic high < dynamic medium). Action orientation enabled high flow even under the suboptimal condition of balance. Sensation seeking increased enjoyment under the suboptimal but arousing dynamic high condition. We discuss dynamic changes in positive affect (seeking and mastering challenge) as an integral part of flow. 相似文献
Objective: Longer telomeres are associated with better health and longevity. This research investigated the relationship between positive psychological dispositional traits and telomere length. Positive traits examined were typical high positive affect, typical low negative affect, life satisfaction, trait mindfulness, trait emotional intelligence, general self-efficacy and optimism.
Design and Measures: One hundred and twenty women and men, with a mean age of 40.92, completed measures of positive characteristics and provided samples for telomere length analysis.
Results: Together the positive dispositional characteristics explained significant variance in telomere length, R = .40. Among the individual characteristics, greater optimism and higher emotional intelligence were associated with longer telomeres after adjustment for age and gender and the association between optimism and telomere length remained significant after adjusting for age and gender as well as the other positive characteristics, with a partial correlation r of .30.
Conclusion: These results in conjunction with previous research findings provide a platform for further exploration of biological pathways connecting positive characteristics such as optimism to telomere length and investigation of the impact of increasing a characteristic such as optimism on telomere functioning. 相似文献
Our aim in this paper is to employ conceptual negotiation to inform a method of rethinking defective food concepts, that is concepts that fail to suitably represent a certain food-related domain or that offer representations that run counter to the interests of their users. We begin by sorting out four dimensions of a food concept: (i) the data upon which it rests and the methodology by which those data are gathered; (ii) the ontology that sustains it; (iii) the social acts that serve to negotiate and establish the concept; (iv) and the aims and values that it fosters. We then discuss the conditions that make a food concept defective, pointing out four types of defects—fragility, polarization, incoherence, and schizophrenia—which we illustrate by means of two specific examples: local food and healthy food.
Our ability to hold a sequence of speech sounds in mind, in the correct configuration, supports many aspects of communication, but the contribution of conceptual information to this basic phonological capacity remains controversial. Previous research has shown modest and inconsistent benefits of meaning on phonological stability in short-term memory, but these studies were based on sets of unrelated words. Using a novel design, we examined the immediate recall of sentence-like sequences with coherent meaning, alongside both standard word lists and mixed lists containing words and nonwords. We found, and replicated, substantial effects of coherent meaning on phoneme-level accuracy: The phonemes of both words and nonwords within conceptually coherent sequences were more likely to be produced together and in the correct order. Since nonwords do not exist as items in long-term memory, the semantic enhancement of phoneme-level recall for both item types cannot be explained by a lexically based item reconstruction process employed at the point of retrieval (“redintegration”). Instead, our data show, for naturalistic input, that when meaning emerges from the combination of words, the phonological traces that support language are reinforced by a semantic-binding process that has been largely overlooked by past short-term memory research. 相似文献
Pursuing personally valued goals in work and family is important for many people, yet research has only partially addressed how individuals can actively manage the work–family interface. We examined the role of action regulation at the work–family interface (AR-WF) as an integrated individual-level approach to attain favorable work–family outcomes through the selection and pursuit of goals at the work–family interface. We investigated the relation of AR-WF to theoretically derived correlates and outcomes in two time-lagged studies with samples from the USA and Germany, based on a newly developed and validated measure to assess AR-WF. Overall, results showed that AR-WF is positively related to dispositional self-regulation, work and family role commitment, work and family goal regulation, and work and family social support. In contrast, AR-WF was largely unrelated to work and family role demands and segmentation or integration boundary enactment. AR-WF further positively related to work and family goal attainment, as well as work–family enrichment beyond related constructs. However, AR-WF was also positively related to increased work-to-family conflict. We discuss how a focus on action regulation can be useful for attaining a better understanding of the active role that people play in managing multiple role demands at the work–family interface.
An especial skill occurs when performance of a single action from within a class of actions produces an advantage in performance. This advantage in a single action over others in the class is presumed to result from large amounts of practice performing the specific action (Keetch, Schmidt, Lee, & Young, 2005). In an experiment involving the learning of a basketball set shot, practice was manipulated to identify whether an especial skill effect emerges at the free-throw line as a result of constant practice conditions in novice performers. After a pretest, which involved set shots across five distances, participants were randomly assigned to one of two intervention groups. A constant practice group (n=10) performed 300 trials of the set shot at the 15 ft free throw line only, whereas a variable practice group (n=10) performed 300 trials across five distances. Shot accuracy increased for both groups as a result of practice at the 15' distance. However, on the posttest, a significant difference was reported between actual and expected scores for the constant practice group only. This finding provided evidence that an effect similar to that seen for especial skills emerges as a result of constant practice. Although an especial skill effect could result from massive amounts of practice, we show it can emerge as a result of short term repetitive practice, indicating that the type, rather than amount, of practice is important. 相似文献
The IZOF-based probabilistic approach provides a methodology to study within-individual patterns of a performer's states. So far, the time course of physiological data before performance have not been investigated within the probabilistic methodology framework. The purpose of this study was to examine the value of the probabilistic approach in the assessment of the time course of physiological indicators of arousal/activation and vigilance during the period preceding the shot, in comparison with the performance-based method.
Design
Longitudinal assessment of psycho-physiological data and performance outcomes was conducted on eight elite pistol shooters in a controlled setting.
Methods
Each participant performed 60 air-pistol shots in 2 sessions. Skin conductance level and cardiac activity were recorded. Affective states intensity was evaluated on a modified 11-point Borg scale. Affect, HR and SC level were evaluated with a Performance-based approach and a Probabilistic method, and results compared at an individual level.
Results
Findings showed the higher effectiveness of the probabilistic method to analyse physiological parameters (skin conductance and heart rate) and to describe the physiological mechanisms associated with shooters’ performance.
Conclusions
The probabilistic method better discerned the contribution of arousal/activation and vigilance to optimal and non-optimal performance in elite shooters, thereby providing a sharper representation of the temporal pattern of performers' states before shooting. From an applied perspective, we believe that the probabilistic approach can help athletes become aware of the subtle variations occurring in their psychophysical states during the preparatory period preceding the shot and not only at the moment of shot release. 相似文献
The current investigation examined whether attachment functioning might mediate the effects of parenting on traits associated with psychopathy. Participants completed the Parental Bonding Instrument, the Experiences in Close Relationships Scale, and the Triarchic Psychopathy Measure within a cross-sectional design. Whilst several recalled parenting variables demonstrated significant correlations with the psychopathy subscales, mediation analyses confirmed that the majority of these effects were mediated by current attachment anxiety and avoidance. Only paternal overprotection maintained a significant direct effect on levels of disinhibition. These findings provide support for the argument that attachment dysfunction may represent a potential mechanism through which parenting practices contribute to the emergence of psychopathy-related traits. Inferences regarding causality and mechanisms of effect are naturally constrained by the cross-sectional design of the current investigation, but the preliminary findings presented warrant further examination within prospective designs. 相似文献
Some aspects of executive function are thought to be dysfunctional in psychopathic individuals. We administered a small battery of neuropsychological tests (spatial alternation task, object alternation task, and Porteus Maze) to two samples of college students and obtained a measure of psychopathy via a self-report questionnaire. Psychopathic traits were related to the tests of object alternation and Porteus Maze but not to the spatial alternation task. Our results support the hypothesis of orbitofrontal cortex (OFC) dysfunction with sparing of dorsolateral prefrontal cortex (DLPFC) in psychopathy and provide a downward extension of this theory to sub-clinical levels of psychopathy. 相似文献
