Medical students who had to undergo an important set of examinations were asked to fill out two questionnaires, the first early in the term, the second 1 or 2 wk before the exams. Students whose anxiety increased substantially between the two questionnaire administrations reported that their thoughts had become more intrusive on a number of parameters including distress, frequency and dismissability. Subjects whose anxiety increased only moderately or not at all reported correspondingly smaller changes in intrusiveness. There was considerable stability in reported cognitions over time, but changes in anxiety were related to changes in reports of thought content. The perceived probability of negative outcomes did not vary over time. These results indicate that changes in anxiety levels over time are related to several parameters of intrusiveness as well as thought content.  相似文献

Relative pitch perception in animals has been difficult to demonstrate. This failing is due in part to stimulus sets that make an absolute pitch solution viable. In Experiment 1, starlings failed to acquire a discrimination that could be solved only on the basis of relative pitch. In Experiment 2, starlings were trained on a smaller set of pitch patterns, for which both absolute and relative pitch solutions were available, then tested with three series of unreinforced probe stimuli. Series 1 assessed stimulus control by absolute pitch. In Series 2, absolute pitch cues dictated one response, and relative pitch cues dictated a different response. Results indicate that starlings extract relative pitch from artificial pitch patterns only after acquiring a discrimination that permits both absolute and relative pitch solutions. Results are discussed in terms of the relative salience of absolute and relative pitch.  相似文献

Sixty-three generally anxious subjects were assigned to anxiety management training, applied relaxation training, relaxation-only, placebo and untreated control conditions. After 6 weeks of treatment, anxiety management training led to reductions on a variety of self-report measures of state and trait anxiety and decreases in maladaptive cognitions during a laboratory stress procedure. On several measures, subjects in anxiety management training differed from relaxation-only and placebo subjects as well as untreated controls. However, treatment effects did not extend to performance and physiological measures of anxiety. Applied relaxation training, which in contrast to anxiety management training lacks structured rehearsal involving the recognition and reduction of tension cues during the treatment sessions, resulted in less consistent decreases in measures of general anxiety.  相似文献

ABSTRACT The Warnock Report fails to reveal an important underlying principle concerning the donation and transference of gametes and embryos. This principle contrasts sharply with the principle that children are non-transferable. Consideration of where to place the line between transferable embryos and non-transferable fetuses, or children, yields a conception of surrogacy that would set it apart from adoption. The paper argues for a coherent system of surrogacy supported by regulative institutions in which surrogacy is seen to facilitate an acceptable form of parenthood.  相似文献

The Euthyphro objection is often perceived, rightly or wrongly, as the king objection to theistic meta-ethics. This paper proposes a response that hasn’t been much explored within the contemporary literature, based on the metaphysics of dispositions and natural law theory. The paper will first contend that there is a parallel between ways theists conceptualise God’s role in creating laws of nature and the ways God creates goods. Drawing upon these parallels I propose a possible response to the dilemma, where this response parallels the dispositionalist response as to how God creates laws of nature. I do this by first explicating a natural law theory of goodness, then suggesting how the ontology of dispositions can be used in a novel way to account for goods, and finally by explaining how all this relates to the dilemma. I conclude the paper by posing some objections to myself and providing some replies.  相似文献

Students attending Seventh-day Adventist (Adventist) schools in Australia have been shown to have better health status and behaviours compared to secular norms, yet these schools cater for a high percentage of non-Adventist students. The purpose of this study was to investigate the influence of religious affiliation (Adventist/non-Adventist) on the health status and behaviours of students attending Adventist secondary schools in Australia. The sample included 1734 students who responded to a health and lifestyle survey that captured demographic details, self-reported height and weight, self-reported health status, mental health and select health behaviours. Students who identified themselves as Adventist reported significantly better health behaviours than the non-Adventist students in several behavioural domains, especially among the male students. However, this did not translate to a difference in health status. Further research is needed to understand the causal mechanisms responsible for the potential health advantage of Adventist students, which may include family or church religious influences.  相似文献
