The present study examined the immediate impact of media portrayals on evaluations of body shape and disordered eating symptomatology in female undergraduates. By using a repeated measures design, participants (N= 42) were exposed on two consecutive occasions to magazine images representing the thin-ideal physique and overweight models. Body satisfaction was recorded both before and after exposure to the images and eating disorder symptomatology was measured following both exposures. Results showed that participants' body satisfaction scores decreased following exposure to the thin-ideal physique and increased following exposure to the larger models. When analysing eating disorder symptomatology, body dissatisfaction and drive for thinness were higher following exposure to slender media images compared to the larger media images. However, exposure to the thin-ideal physique did not increase disordered eating behaviours. These results provide evidence that one brief exposure to media images could exert immediate impact on some behaviours, attitudes and perceptions. 相似文献

Differences in methods of knowing correlate with differences in concepts about what is known. This is an underlying issue in science and religion. It is seen, first, in Arthur Peacocke's reasoning about God as transcendent and personal, is based on an assumption of correlative thinking that like causes like. This contrasts with a notion of causation in empirical science, which explains the emergence of new phenomena as originating from temporally prior phenomena quite unlike that which emerges. The scientific understanding of causation is compatible with a naturalistic theism that holds a nonpersonal model of God as the creative process. However, focusing on the immanence of God, there is a second correlation between methods of knowing and concepts of God. Classical empiricism, used by science, correlates with God understood nonpersonally as the creative process. Radical empiricism, in which feelings and not only sense perceptions have cognitive import, opens up the possibility that one can experience Peacocke's personal, panentheistic God as pattern‐forming influence. I illustrate this second method‐concept correlation with a personal experience. 相似文献

Ternary exclusive or is the (two valued) truth function thatis true just in case exactly one of its three arguments is true.This is an interesting truth function, not definable in termsof the binary exclusive or alone, although the binary case isdefinable in terms of the ternary case. This article investigatesthe types of truth functions that can be defined by ternaryexclusive or, and relates these findings to the seminal workof Emil Post. 相似文献

Numerous grounds have been offered for the view that healthcare workers have a duty to treat, including expressed consent, implied consent, special training, reciprocity (also called the social contract view), and professional oaths and codes. Quite often, however, these grounds are simply asserted without being adequately defended or without the defenses being critically evaluated. This essay aims to help remedy that problem by providing a critical examination of the strengths and weaknesses of each of these five grounds for asserting that healthcare workers have a duty to treat, especially as that duty would arise in the context of an infectious disease pandemic. Ultimately, it argues that none of the defenses is currently sufficient to ground the kind of duty that would be needed in a pandemic. It concludes by sketching some practical recommendations in that regard. 相似文献

Source monitoring refers to cognitive processes involved in making attributions about the origins of memories, knowledge, and beliefs. One particular type of source monitoring with ample practical significance is reality monitoring, i.e., the ability to discriminate between internally vs. externally generated memories. Abundant evidence indicates that exposure to acute stress enhances declarative memory consolidation. To date, no study has looked at whether exposure to acute stress during the consolidation phase may promote reality monitoring performance. The authors examined this by administering cold pressor stress (CPS) or a control procedure to participants (N = 80) after they had either performed or only imagined performing simple motor acts, and assessing reality monitoring 24 h later. When compared with the control condition, CPS significantly elevated salivary free cortisol concentrations and enhanced reality monitoring. Stress-induced cortisol responses, however, were found not to be related to improved reality monitoring performance. Our findings are consistent with the view that post-learning stress hormone-related activity may modulate source memory consolidation. 相似文献
