Previous studies have suggested that pre-operative anxiety consists of different aspects each with its own specific influence on post-operative state. This study investigated the influence of different aspects of transient anxiety i.e. state anxiety, specific anxiety, tension, observed anxiety and the amount of thinking about surgery, on post-operative anxiety and physical complaints in 126 patients undergoing lumbar surgery. Results showed that pre-operative state anxiety, specific anxiety, tension and observed anxiety each contributed uniquely to the prediction of post-operative anxiety after control for age, sex and medical variables. Tension showed a negative contribution, indicating that, when the effects of other anxiety aspects were removed, patients with high tension showed less post-operative anxiety than patients with low tension. The three other anxiety variables showed a positive contribution. Regarding postoperative physical complaints, only specific anxiety showed a positive significant contribution to the prediction. Results will be discussed in relation to the adaptation to surgery and to Janis' theory that experiencing moderate levels of anxiety is beneficial for recovery. 相似文献

Relatively few studies of the psychobiology of hypersexuality have been undertaken. Nevertheless, the literature does suggest the possibility of a neurobiology of hypersexuality. Three cases of hypersexual behavior are presented in the context of neuropsychiatric disorders, and the literature on this phenomenon is briefly reviewed. These case studies and the literature provide evidence that different brain systems may play a role in this disorder. Frontal lesions may be accompanied by disinhibition, including impulsive hypersexual response to external cues, while striatal lesions may be accompanied by repetitive triggering of internally generated response patterns. Temporal-limbic lesions may be accompanied by disturbances in sexual appetite itself, including change in the direction of sexual drive. These case studies demonstrate that a neurobiology of hypersexuality may prove of some heuristic value in the clinic. However, further research is required to consolidate the literature in this area. 相似文献

Two important parenting strategies are to impose one's power and to use reasoning. The effect of these strategies on children's evaluation of testimony has received very little attention. Using the epistemic vigilance framework, we predict that when the reasoning cue is strong enough it should overcome the power cue. We test this prediction in a population for which anthropological data suggest that power is the prominent strategy while reasoning is rarely relied on in the interactions with children. In Experiment 1, 4‐ to 6‐year‐old children from a traditional Maya population are shown to endorse the testimony supported by a strong argument over that supported by a weak argument. In Experiment 2, the same participants are shown to follow the testimony of a dominant over that of a subordinate. The participants are then shown to endorse the testimony of a subordinate who provides a strong argument over that of a dominant who provides either a weak argument (Experiment 3) or no argument (Experiment 4). Thus, when the power and reasoning cues conflict, reasoning completely trumps power. 相似文献

Thirty-two female participants in a mobilising labour market programme offering temporary, alternative employment in Sweden were followed longitudinally for one year, including a six month post participation follow-up period. It can be hypothesised that an important aspect of the physiological effects of unemployment is a change in the balance between anabolic and catabolic activities in the body and that re-employment should lead to a shift towards anabolism. An earlier study of a smaller subset of the data, however, including both men and women, showed increased prolactin and decreased dehydroepiadrosterone sulphate (DHEA-s) levels, contrary to the initial hypothesis. In the present analysis, intended to elucidate these results, psychophysiological data were summarised in two indices, one connected with anabolism (made up of testosterone and DHEA-s) and one with catabolism (prolactin, gamma-glutamyl transferase, aspartate amino transferase, alpha levuline amino transferase, and body mass index). In addition, self-rated anxiety, depression, hopelessness and personal control were analysed. The results indicate that the effect of 'better' activities within the programme was a temporary increase in anabolism, possibly indicating lower stress levels, and the effect of 'worse' activities, on the one hand, a temporary decrease in the catabolic index, probably reflecting repressed alcohol consumption, and, on the other hand, impaired anabolism. There was also a general but transient decrease in depressiveness measured by the Hospital Anxiety and Depression Scale. The results seem to imply that it is difficult to achieve lasting effects through a relatively short participation in a mobilising programme. 相似文献

There are two distinct interpretations of the role that Feynman diagrams play in physics: (i) they are calculational devices, a type of notation designed to keep track of complicated mathematical expressions; and (ii) they are representational devices, a type of picture. I argue that Feynman diagrams not only have a calculational function but also represent: they are in some sense pictures. I defend my view through addressing two objections and in so doing I offer an account of representation that explains why Feynman diagrams represent. The account that I advocate is a version of that defended by Kendall Walton, which provides us with a basic characterization of the way that representations in general work and is particularly useful for understanding distinctively pictorial representations – in Walton’s terms, depictions. The question of the epistemic function of Feynman diagrams as pictorial representations is left for another time. 相似文献
