Two experiments were conducted to verify the influence of various mental simulations on the effectiveness and persistence of weight loss processes. In study one, 40 female students (aged 19–27, M = 23) who were eager to lose weight were randomly assigned to one of four groups: positive outcome simulation, process simulations, mixed simulations (process followed by negative outcome), and control (no simulations). Students from the mixed and process simulation groups lost significantly more weight after five weeks than participants from the outcome simulation and control groups. A total of 106 females (aged 19–45, M = 29) participated in study two, in which five types of mental simulations were tested. Besides the images used in study one, process followed by positive outcome simulations and negative outcome simulations were implemented. Results showed that process followed by positive outcome simulations lead to the highest persistence in the weight loss process, while process followed by negative outcome simulations induced the greatest reduction in weight. Both studies revealed self-regulatory benefits from mental simulations in difficult and long-term personal goal attainment. 相似文献
Contextual action theory is presented as a conceptual framework useful for grounding the recent work in counselling and career development called Life Design. Based on the premise of the goal-directed nature of human action, this approach has links to language in theories of naive action and attribution, and theory of mind. Contextual action theory has an associated research method that has been used to generate a range of research studies that have described actions and projects in the career development and counselling domains. The link that contextual action theory provides between research and practice allows the identification of five tasks for the counselling practitioner informed by this approach. 相似文献
Recent research has revealed that a simple action (pressing a computer key) produced in response to a visual object prioritizes features of that object in subsequent visual search. The effects of simple action, however, have only been studied with search displays that required serial search. Here we explored whether simple actions have an effect when the target in visual search is always a salient singleton. Participants viewed a coloured shape at the beginning of each trial, and sometimes they acted (pressed the space bar) in response to it. In the subsequent search task, after acting (but not after viewing), the previously-seen colour affected search performance even though the target was always a salient singleton and the colour was uninformative. The results reveal that prior action can interact with bottom-up salience during search. Implications for our understanding of both visual search and repetition priming are discussed. 相似文献
While the initial purpose of this article was to outline online collective action (OCA) towards promoting the rights of hijab-wearing Muslim women in the workplace, it became apparent that there were substantial impediments to this solidarity. Thus, the bulk of it takes up these obstacles, arguing that American hijabis face structural discrimination and Muslims in the United States are subjected to heightened discrimination when they are highly visible to the mainstream culture. This article reviews two cases of workplace discrimination against hijabis and the reactions to these incidents on the Huffington Post, Los Angeles Times, and hijab-oriented blogs. Findings indicate that intolerance of Muslims is prevalent across various political affiliations and apprehension associated with hijabi rights could be related to the perceived decline of white privilege. The analysis also demonstrates that there may be impediments to solidarity with hijabi rights within Muslim communities due to disagreements on the Qur’anic mandate of modesty, divergent perspectives on how Muslims can best promote their rights and ensure their safety, and misunderstandings related to the rights guaranteed under reasonable accommodation. Despite the various obstacles to solidarity with hijabis, the article traces various forms of OCA at local, national and international levels that were encountered on social media platforms. 相似文献
Objective: Examine psychosocial mediators of the effects of high vs. low-dose resistance training (RT) maintenance interventions among older (ages 50–69), overweight and pre-diabetic adults.
Design: Participants (N = 123) completed a three-month supervised RT initiation phase and were subsequently randomised (time 1) to high or low-dose six-month unsupervised RT maintenance interventions (time 2), followed by a six-month no-contact phase (time 3).
Main Outcome Measures: Online measures of putative mediators and RT behaviour.
Results: RT intervention condition (high vs. low dose) had significant effects on change from time 1 to time 2 in behavioural expectation, self-regulation and perceived satisfaction (f2 = .04–.08), but not outcome expectancies, RT strategies or behavioural intentions (f2 ≤ .02). Change in each of the putative mediators, except for outcome expectancies (f2 ≤ .02), had significant effects on RT behaviour at times 2 (f2 = .12–.27) and 3 (f2 = .23–.40). In a multiple mediation model, behavioural expectation (f2 = .11) and self-regulation (f2 = .06) mediated the effects of RT intervention condition on time 2 RT behaviour, whereas perceived satisfaction did not (f2 = .01). Self-regulation was a significant mediator of intervention effects on time 3 RT behaviour (f2 = .11), but behavioural expectation and perceived satisfaction were not (f2 = .04).
Conclusions: Findings suggest that behavioural expectation and self-regulation are appropriate targets for RT maintenance interventions among at-risk older adults. 相似文献
Perhaps the greatest irony about the contemporary religion-science dialogue is the fact that, despite their own strongly articulated denials, many thinkers implicitly accept the "warfare" thesis of A. D. White—that is, they agree with White that traditional theology has proved unable to engage science in fruitful conversation. More than most others, John Polkinghorne understands just how badly White misread the history of Christianity and science, and how much theology has been impoverished by its failure to challenge this core assumption of modernity. 相似文献
