This article argues that Bowers and Paternoster’s emphasis on a moral community marks an important step towards a more ethical and effective approach to anti-doping. However, it also argues that the authors’ proposed strategies undermine their stated goal of effectively engaging athletes as partners in anti-doping efforts and raise ethical concerns. Their proposed emphasis on exploiting shaming as a punishment and their general view of athletes as adversaries fosters mistrust between athletes and those who enforce the anti-doping rules. Instead, this article describes a model for empowering athletes as stakeholders in anti-doping policy as a means to provide anti-doping rules with increased moral legitimacy among athletes.  相似文献

In three experiments, the effect of cuing, at the point of test, on memory for order and/or position was investigated. Experiment 1 used a partial reconstruction of order task to demonstrate a mnemonic benefit of part-set cuing at the time of test; this result is used to argue that people may commonly use interitem associative information, rather than just position information, to help them remember serial order. Experiment 2 replicated these findings and simultaneously demonstrated the mnemonic detriment that part-set cuing typically produces in free recall. Experiment 3 showed that cues presented at test will either help or hinder reconstruction of order, depending on whether those cues are consistent or inconsistent with the original presentation order. The results of all three experiments are discussed within the framework of position and associative theories of serial order memory.  相似文献

The Hospital Anxiety and Depression Scale (HADS; Zigmond - Snaith, 1983) is widely used; however, its factor structure is unclear, with studies reporting differing unidimensional, two-factor and three-factor models. We aimed to address some key theoretical and methodological issues contributing to inconsistencies in HADS structures across samples. We reviewed existing HADS models and compared their fit using confirmatory factor analysis (CFA). We also investigated methodological effects by comparing factor structures derived from Rasch and Principal Components Analysis (PCA) methods, as well as effects of a negative wording factor. An Australian community-dwelling sample consisting of 189 females and 158 males aged 17–86 (M = 35.73, SD = 17.41) completed the 14-item HADS. The Rasch Analysis, PCA and CFA all supported the original two-factor structure. Although some three-factor models had good fit, they had unacceptable reliability. In the CFA, a hierarchical bifactor model with a general distress factor and uncorrelated depression and anxiety subscales produced the best fit, but the general factor was not unidimensional. The addition of a negative wording factor improved model fit. These findings highlight the effects of differing methodologies in producing inconsistent HADS factor structures across studies. Further replication of model fit across samples and refinement of the HADS items is warranted.  相似文献

Visual adaptation is known to bias perception away from the properties of the adapting stimuli, toward opposite properties, resulting in perceptual aftereffects. For example, prolonged exposure to a face has been shown to produce an identity aftereffect, biasing perception of a subsequent face toward the opposite identity. Such repulsive aftereffects have been observed for both visually perceived and visually imagined faces, suggesting that both perception and imagery yield typical aftereffects. However, recent studies have reported opposite patterns of aftereffects for perception and imagery of face gender. In these studies, visually perceived faces produced typical effects in which perception of androgynous faces was biased away from the gender of the adaptor, whereas imagery of the same stimuli produced atypical aftereffects, biasing the perceived gender of androgynous faces toward the gender of the adaptor. These findings are highly unusual and warrant further research. The present study aimed to gather new evidence on the direction of gender aftereffects following perception and imagery of faces. Experiment 1 had participants view and imagine female and male faces of famous and non-famous individuals. To determine the effect of concomitant visual stimulation on imagery and adaptation, participants visualized faces both in the presence and in the absence of a visual input. In Experiment 2, participants were adapted to perceived and imagined faces of famous and non-famous actors matched on gender typicality. This manipulation allowed us to determine the effect of face familiarity on the magnitude of gender aftereffects. Contrary to evidence from previous studies, our results demonstrated that both perception and imagery produced typical aftereffects, biasing the perceived gender of androgynous faces in the opposite direction to the gender of the adaptor. Famous faces yielded largest adaptation effects across tasks. Experiment 2 confirmed that these effects depended on familiarity rather than on sexual dimorphism. In both experiments, this effect was greater for perception than imagery. Additionally, imagery of famous faces produced strongest aftereffects when it was performed in the absence of visual stimulation. The implications of these findings are discussed.  相似文献

Social anxiety and depression are highly comorbid conditions. Although this has led researchers to suggest that social anxiety may convey risk for depression, few studies have examined mechanisms of comorbidity between these two conditions. The current study tested two mechanisms of comorbidity between symptoms of these disorders: brooding and excessive reassurance seeking. The data were evaluated in an undergraduate sample assessed three times over a 2 month period. Results suggested that brooding mediated the relationship between social anxiety at Time 1 and depression at Time 3, although no evidence was found for excessive reassurance-seeking as a mediator of these two variables. These findings support recent research suggesting that brooding may be a transdiagnostic process. Theoretical and clinical implications are discussed.  相似文献

Many people believe that the mind is an epistemic refuge of sorts. The idea is that when it comes to certain core mental states, one's being in such a state automatically puts one in a position to know that one is in that state. This idea has come under attack in recent years. One particularly influential attack comes from Timothy Williamson (2000), who argues that there is no central core of states or conditions—mental or otherwise—to which we are guaranteed epistemic access. In Williamson's words, we are cognitively homeless. In this paper I will argue that Williamson's argument for the conclusion that we are cognitively homeless fails. Then I will show that there is a class of phenomenal states that constitutes a substantial cognitive refuge. When all is said and done, I will have both defended and shed light on our cognitive home.  相似文献

Converging findings from recent research suggest a functional relationship between attention-deficit/hyperactivity disorder (ADHD)-related hyperactivity and demands on working memory (WM) in both children and adults. Excessive motor activity such as restlessness and fidgeting are not pathognomonic symptoms of ADHD, however, and are often associated with other diagnoses such as generalized anxiety disorder (GAD). Further, previous research indicates that anticipatory processing associated with anxiety can directly interfere with storage and rehearsal processes of WM. The topographical similarity of excessive motor activity seen in both ADHD and anxiety disorders, as well as similar WM deficits, may indicate a common relationship between WM deficits and increased motor activity. The relationship between objectively measured motor activity (actigraphy) and PH and visuospatial WM demands in adults with ADHD (n = 21), adults with GAD (n = 21), and healthy control adults (n = 20) was examined. Although all groups exhibited significant increases in activity from control to WM conditions, the ADHD group exhibited a disproportionate increase in activity, while activity exhibited by the GAD and healthy control groups was not different. Findings indicate that ADHD-related hyperactivity is uniquely related to WM demands, and appear to suggest that adults with GAD are no more active relative to healthy control adults during a cognitively demanding laboratory task.  相似文献

Contingent, behavior‐specific praise is universally recommended as an effective tool to increase students’ academic achievement and proscocial behavior. Despite this recommendation, little research has examined the effects of training teachers to increase their praise‐to‐behavior correction ratio in classroom settings. This study evaluated the effects of training teachers to provide a 1:1 ratio of praise‐to‐behavior correction to decrease student disruption in three general‐education classrooms. Three urban middle‐school general‐teachers who exhibited very low rates of praise participated in the study. Teachers received training, including modeling and performance feedback, to achieve a 1:1 ratio of praise‐to‐behavior correction administered within a multiple‐baseline across participants design. Results demonstrated that (a) the teachers were able to achieve and maintain a 1:1 praise‐to‐behavior correction ratio; (b) a reduction in student disruption coincided with teachers’ use of a 1:1 praise‐to‐behavior correction ration; and (c) two teachers evidenced moderate levels of generalization to classrooms where no training took place. Implications for practitioners and future research are discussed. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献
