Childhood obesity trends have increased dramatically over the past three decade’s. The purpose of this quantitative systematic review is to provide an update of the evidence, illustrating the efficacy of childhood obesity treatment, considering whether treatment fidelity has been measured and/or reported and whether this related to the treatment effect size. Searches revealed 61 relevant articles published from January 2000 to 2009, including both randomized and non-randomized controlled trials of childhood and adolescent obesity treatment interventions. The review identified scant measurement and reporting of issues around treatment fidelity, an increase in the number of interventions outside of the US, (particularly across Europe) and an emergence of studies involving older children and adolescents in a range of settings. Interventions comprising a dietary, exercise, and behavioral component, supported by family involvement and delivered by trained interventionists in specialized or supervised settings, appeared to offer a potentially effective treatment for obesity. However, concern remains over study quality (particularly sample size), dropout rates and study design. Variations in outcome measures and intervention designs means generalizable conclusions cannot be easily be made. Of greater concern is the lack of consideration for treatment fidelity, which has implications for the transfer of knowledge and the reliability of interventions. Conclusions from the review include; the need for increased accuracy of reporting and objective measurement of treatment fidelity; the need for further investigation of potential cost-effective treatment options (including maintenance strategies to enhance sustainability of current interventions); and an increase in the number of longitudinal trials beyond 1?year in duration. 相似文献

Observers find a target item more quickly when they have foreknowledge of target-defining attributes, such as identity, color, or location. However, it is less clear whether foreknowledge of nontarget attributes can also speed search. Munneke, Van der Stigchel, and Theeuwes Acta Psychologica 129:101?C107, (2008) found that observers found the target more quickly when they were cued to ignore a region of space where a target would not appear. Using a similar paradigm, we explored the effects of cueing nontarget features on search. We found that when we cued observers to ignore nontarget features, search was slowed. The results from a probe-dot detection task revealed that this slowing occurred because, paradoxically, observers initially selected an item appearing in the to-be-ignored color. Finally, we found that cueing nontarget features sped search when placeholders matching the location of the to-be-ignored color preceded presentation of the search display by at least 800?ms; thus, it appears that some limited inhibition of to-be-ignored items occurs following selection. Taken together, these results suggest that observers are unable to explicitly avoid selection of items matching known nontarget features. Instead, when nontarget features are cued, observers select the to-be-ignored feature or the locations of objects matching that feature early in search, and only inhibit them after this selection process. 相似文献

Broadly defined, social dilemmas involve a conflict between immediate self-interest and longer-term collective interests. These are challenging situations because acting in one’s immediate self-interest is tempting to everyone involved, even though everybody benefits from acting in the longer-term collective interest. As such, greater knowledge of social dilemmas should help us understand not only the theoretical puzzles of why people cooperate (or not) but also the ways in which cooperation in groups and organizations can be maintained or promoted. This article reviews different types of social dilemmas, highlights recent developments in the field (especially within psychology), and suggests some new avenues for future research. We illustrate that the field of social dilemma is growing and flourishing in terms of theory, interdisciplinary collaboration, and applicability, producing insights that are novel, replicable, and applicable to many social situations where short-term self-interest is at odds with the long-term interests of teams, organizations, or nations. 相似文献

Action perception is selective in that observers attend to and encode certain dimensions of action over others. But how flexible is action perception in its selection of perceptual information? One possibility is that observers consistently attend to particular dimensions of action over others across different contexts. Another possibility, tested here, is that observers flexibly vary their attention to different dimensions of action based on the context in which action occurs. We investigated 9.5-month-old infants’ and adults’ ability to attend to drop height under varying contexts—aiming to drop an object into a narrow container versus a wide container. We predicted differential attention to increases in aiming height for the narrow container versus the wide container because an increase in aiming height has a differential effect on success (i.e., getting the object into the container) depending on the width of the container. Both adults and infants showed an asymmetry in their attention to aiming height as a function of context; in the wide container condition increases and decreases in aiming height were equally detectable, whereas in the narrow container condition observers more readily discriminated increases over decreases in aiming height. These results indicate that action perception is both selective and flexible according to context, aiding in action prediction and infants’ social–cognitive development more broadly. 相似文献

Intimate partner relationship distress is associated with a wide range of negative adult and child outcomes. The transition to parenthood is often a time in the life of a couple where relationship distress increases and satisfaction and intimacy decrease and thus is an ideal time for targeted intervention. The Healthy Nests (HN) intervention is a three-meeting, strength-focused couples intervention for first-time parents designed to decrease maladaptive relationship conflict and increase couple well-being. The authors conducted a mixed-methods exploratory study investigating participants' overall experiences with the HN intervention and measured outcomes associated with relationship satisfaction, help seeking, father involvement, substance use, and depression. A total of 130 parents (65 dyads) participated in a randomized intervention and educational materials–only alternative intervention. Twenty dyads were interviewed as a part of the qualitative portion of the study. While the authors did not find significant quantitative effects on key outcomes, the qualitative findings suggested that participants had a positive experience with the HN intervention and indicated it was useful to have designated time and space to communicate as a couple. Qualitative findings also suggest that the focus on “aspects of strength” and “areas of change” in their relationship was useful. Implications for practice, research, and training are discussed. 相似文献

Purpose
This study contributes to the ecological validity of resume research by systematically examining the impression management (IM) content of actual resumes and cover letters and empirically testing the effect on applicant evaluation.Design/methodology/approach
A content analysis of the frequency and intensity of IM tactic use in 60 resumes and cover letters was completed (Study 1). Next, an experiment was conducted in which IM tactic use was manipulated and the effect on applicant evaluation examined, using a sample of MTurk workers as evaluators (Study 2).Findings
In Study 1, four self-promotion categories, three ingratiation categories, and one hybrid category were delineated. In Study 2, ingratiation and lower intensity self-promotion were found to increase perceptions of job and organization fit.Implications
Employers should be aware that resumes and cover letters contain IM tactics that may influence applicant evaluation. In addition, employment training programs might communicate the benefits of using ingratiation and lower intensity self-promotion, while emphasizing the importance of accurately conveying one’s qualifications. Furthermore, the present taxonomy of IM resume content might be applied to resume database search engines to identify and index IM tactic use.Originality/value
This research is the first to develop a taxonomy of IM tactics based on actual resumes and cover letters and may facilitate more comprehensive manipulations of IM tactic use and better integration of IM research across the selection process.257.

In a simple reaction time (RT) experiment, visual stimuli were stereoscopically presented either to one eye (single stimulation) or to both eyes (redundant stimulation), with brightness matched for single and redundant stimulations. Redundant stimulation resulted in two separate percepts when noncorresponding retinal areas were stimulated, whereas it resulted in a single fused percept when corresponding areas were stimulated. With stimulation of noncorresponding areas, mean RT was shorter to redundant than to single stimulation, replicating the redundant signals effect (RSE) commonly found with visual stimuli. With stimulation of corresponding areas, however, no RSE was observed. This suggests that the RSE is driven by the number of percepts rather than by the number of stimulated receptors or sensory organs. These results are consistent with previous findings in the auditory modality and have implications for models of the RSE. 相似文献

Decentering has been proposed as a potential mechanism of mindfulness-based interventions but has received limited empirical examination to date in experimental studies comparing mindfulness meditation to active comparison conditions. In the present study, we compared the immediate effects of mindful breathing (MB) to two alternative stress-management techniques: progressive muscle relaxation (PMR) and loving-kindness meditation (LKM) to test whether decentering is unique to mindfulness meditation or common across approaches. Novice meditators (190 female undergraduates) were randomly assigned to complete one of three 15-min stress-management exercises (MB, PMR, or LKM) presented by audio recording. Immediately after the exercise, participants completed measures of decentering, frequency of repetitive thoughts during the exercise, and degree of negative reaction to thoughts. As predicted, participants in the MB condition reported greater decentering relative to the other two conditions. The association between frequency of repetitive thought and negative reactions to thoughts was relatively weaker in the MB condition than in the PMR and LKM conditions, in which these two variables were strongly and positively correlated. Consistent with the construct of decentering, the relative independence between these two variables in the MB condition suggests that mindful breathing may help to reduce reactivity to repetitive thoughts. Taken together, results help to provide further evidence of decentering as a potential mechanism that distinguishes mindfulness practice from other credible stress-management approaches. 相似文献

In this essay, I respond to Tim Lewens’s proposal that realists and Strong Programme theorists can find common ground in reliabilism. I agree with Lewens, but point to difficulties in his argument. Chief among these is his assumption that reliabilism is incompatible with the Strong Programme’s principle of symmetry. I argue that the two are, in fact, compatible, and that Lewens misses this fact because he wrongly supposes that reliabilism entails naturalism. The Strong Programme can fully accommodate a reliabilism which has been freed from its inessential ties to naturalism. Unlike naturalistic epistemologists, the Strong Programme’s sociologistic reliabilist insists that all scientific facts are the product of both natural and social causal phenomena. Anticipating objections, I draw on Wittgenstein’s rule‐following considerations to explain how the sociologistic reliabilist can account for standard intuitions about the objective elements of knowledge. I also explain how the Strong Programme theorist can distinguish between a belief’s seeming reliable and its being reliable.
