IntroductionControlled and autonomous motivational factors from self-determination theory have previously been highlighted as key factors in eating regulation. The present study examined controlled motives as an overarching motivational factor in eating dysregulation and examined its effects on dieting behaviour for those who are underweight, overweight or obese.ObjectiveTo examine whether the influence of controlled motives on dieting behaviour would be moderated by body mass index (BMI). Specifically, it was hypothesised that controlled motives would be associated with high levels of dieting behaviour in underweight individuals and low levels of dieting behaviour in individuals classified as overweight or obese.MethodOne hundred and thirty-seven participants completed the measures of height, weight, and motivation and intentions towards watching their diet and subsequently completed a measure of dieting behaviour two weeks later.ResultsModerated regression and simple slopes analyses provided support for the hypothesised effects at underweight, overweight, and obese range BMIs.ConclusionThe effect of controlled motives on dieting behaviour is dependent upon BMI and therefore varies across underweight, overweight, and obese individuals. The implications of controlled motives and external pressures to watch one's diet are discussed.  相似文献

IntroductionA recent study (Friese et al., 2012) involving two major political elections in the US and Germany reported that voting behavior was better predicted by explicit than implicit attitudes for both decided and undecided voters and that when voting behavior was predicted by implicit attitudes, the prediction was better for decided than undecided voters.ObjectiveWe conducted a comparable study for the 2012 French presidential election using voter volatility as a measure of voter decidedness, in order to test the generalizability of the findings of Friese et al. (2012).MethodParticipants’ voting intention, explicit and implicit attitudes towards the candidates Sarkozy and Hollande were collected during the 2 weeks separating the two rounds of the election.ResultsOur findings confirm that explicit attitudes outperform implicit attitudes when predicting voting choice, but not that the relationship between implicit attitudes and voting intention is moderated by voter decidedness.ConclusionFurther research is needed in order to test whether the moderation of implicit attitudes by voter decidedness is a robust finding or not.  相似文献

IntroductionAcademic failure and dropout are pervasive challenges at all levels of the education system. Research so far pointed out different aspects of this large phenomenon. On the one hand, some scholars have argued that social support is a key factor to foster learning and persistence. On the other hand, some other scholars have rather highlighted the role of student motivation and engagement itself in improving performance on academic tasks. In this article, we tested theoretical models that combine the two approaches in a whole process.AimsWe aimed at clarifying (1) the specific contribution of several sources of perceived social support to academic performance, and (2) the mediation role of motivation and engagement in the relationships between perceived social support and performance.MethodThe sample consisted of 226 last year university students. Structural equation modeling analyses were used to test the hypothesized associations.ResultsStructural equation modeling analysis revealed that institutional and supervisor support were associated with motivation, which in turn predicted greater behavioral, cognitive and emotional engagement. Further, behavioral engagement was the unique contributor of academic performance at the master's thesis.ConclusionThe results clarify the specific contribution of different sources of perceived social support and underline the importance of the supervisor and the institution. They also underline the importance of considering different sources of perceived social support at the same time. Finally, theoretical assumptions concerning the mediational role of motivation were confirmed.  相似文献

This article aims to contribute to the fields of emotional geographies and geographies of sexualities by exploring the relationship between emotions and gender, sexuality, and ‘race’ in sexualised night-time leisure spaces. By drawing on ethnographic research conducted in Manchester's Gay Village, the article highlights the importance of taking into account intersections of social identities when exploring how people feel in certain spaces. It explores how relations of ‘othering’ work through emotions, in particular how people are othered through feelings of comfort and safety. Whilst these feelings are triggered by a particular reading of bodies and spaces, they also produce bodies and spaces that are gendered, sexualised, and racialised (and classed). The article offers a rethinking of comfort and safety as not just feelings individuals have but as being constitutive of sexual, gender, and racial subjectivities and spaces.  相似文献

This article focuses on parents’ role in overweight adolescents’ motivation to diet and successful weight loss. The study employed Self-Determination Theory (SDT) as the theoretical framework (Deci & Ryan, 2000, 2011). Ninety-nine participants (ages 20–30) who had been overweight during adolescence according to their Body Mass Index (BMI mean = 25, SD = 1.6), completed retrospective questionnaires about their motivation to diet and their parents’ behavior in the context of dieting. Findings from a structural equation modeling analysis suggested that participants who viewed their parents’ as more need-supportive demonstrated more autonomous motivation to diet, which, in turn, contributed to their successful weight loss. The findings highlight the importance of parental support of adolescents’ psychological needs in the quality of their motivation to diet. This is an important insight for parents and professionals who aim to encourage more constructive parent involvement in adolescents’ dieting and well-being.  相似文献

Data from 115,052 active United States military personnel were analyzed to explore links between contact with gay people and attitudes about repealing “Don’t Ask, Don’t Tell.” Results showed that prejudice against homosexuals significantly mediated the association between contact and supporting repeal of “Don’t Ask, Don’t Tell”; quality of contact in the military was a stronger predictor than other measures of contact. Quality and quantity of contact interacted: more contact quantity had opposing statistical effects on policy attitudes for people experiencing high versus low quality contact. Findings are discussed in terms of contact theory, the association between intergroup attitudes and policy preferences, and practical implications for situations in which groups’ access to new positions or roles is limited, and hence contact opportunities are rare.  相似文献

Sense of agency refers to the experience that one’s self-generated action causes an event in the external environment. Here, we review the behavioural and brain evidence of aberrant experiences of agency in movement disorders, clinical conditions characterized by either a paucity or an excess of movements unrelated to the patient’s intention. We show that specific abnormal agency experiences characterize several movement disorders. Those manifestations are typically associated with structural and functional brain abnormalities. However, the evidence is sometimes conflicting, especially when considering results obtained through different agency measures. The present review aims to create order in the existing literature on sense of agency investigations in movement disorders and to provide a coherent overview framed within current neurocognitive models of motor awareness.  相似文献

Efficient methods of analysis readily available for clinicians continue to be limited within neuropsychological assessment at the raw data level. Here, a novel approach for generating predictive response patterns and analysing neuropsychological raw data is offered. In order to assess the usefulness of association rule learning as an analysis tool for neuropsychological raw data, Frequent Pattern Growth (FP-Growth) was used to mine patterns from the Consortium to Establish a Registry for Alzheimer’s Disease Neuropsychological Battery (CERAD-NB) database. Complete assessment data for 84 post-mortem confirmed Alzheimer’s disease (AD) cases and 294 age, race, and education matched controls were analysed across baseline and one-year follow-up using FP-Growth, for the purpose of assessing the clinical utility of a finer analysis at the raw data level and the feasibility of predicting response patterns for clinical/control groups. Output from FP-Growth, in terms of the number of frequent itemsets retained across both evaluation timepoints, was discernable between controls, mild, and moderate to severe Alzheimer’s disease cases (p < .001, and η2 = .488). Patterns within raw data scores, both in terms of frequent itemsets and predictive association rules, appear to be differentiable across groups within neuropsychological analysis, which indicates that FP-Growth is applicable as a supplementary analysis tool for neuropsychological assessment by means of offering an additional level of data analysis, predictive item response capabilities, and aiding in clinical decision making.  相似文献

Companies utilizing contingent workers face a dilemma between the need to employ a flexible (i.e., low fixed-cost) work force and the need to employ a work force providing performance above and beyond the call of duty. One potential solution to this dilemma is to determine ways to promote the commitment and high performance of temporary employees. To that end, we conducted a study examining factors influencing organizational citizenship behavior (OCB) performance in temporary employees. Our results support or partially support hypotheses proposing that 1) job attitudes held by the temporary employee about the client organization were related to OCB performance in the client organization, 2) job attitudes held by the temporary employee about the staffing agency were related to OCB performance in the client organization, and 3) the employee's motivation for taking an assignment is related to OCB performance. Implications for enhancing OCB performance in temporary employees are discussed.  相似文献
