Information-processing biases of attention toward and interpretation of threat were measured in 29 undergraduates during a period of low academic stress. During a later period of high academic stress, participants were interviewed about their emotional response: anxious and depressive symptoms, and positive and negative affect. Anxiety symptoms at follow-up were predicted by attention to masked threat stimuli, while negative affect at follow-up was predicted by interpretation of ambiguous items as threatening. Results suggest that although attentional processes appears to play a role in the development of anxiety symptoms, the experience of negative affect during stress may be regulated by more interpretive processes.  相似文献

‘Contract cheating’ has recently emerged as a form of academic dishonesty. It involves students contracting out their coursework to writers in order to submit the purchased assignments as their own work, usually via the internet. This form of cheating involves epistemic and ethical problems that are continuous with older forms of cheating, but which it also casts in a new form. It is a concern to educators because it is very difficult to detect, because it is arguably more fraudulent than some other forms of plagiarism, and because it appears to be connected to a range of systemic problems within modern higher education. This paper provides an overview of the information and literature thus far available on the topic, including its definition, the problems it involves, its causal factors, and the ways in which educators might respond. We argue that while contract cheating is a concern, some of the suggested responses are themselves problematic, and that best practice responses to the issue should avoid moral panic and remain focussed on supporting honest students and good academic practice.  相似文献

There are strong social pressures for U.S. females, particularly those of European heritage, to achieve and maintain an extremely low body weight. These pressures are reflected in a variety of media sources, including advertising. We argue that valuing thinness, exposure to thinness-depicting media, and lacking skepticism about tobacco advertisements have adverse effects on young women's decisions about smoking, particularly smoking for weight control. We tested these hypotheses in a study of 188 female undergraduates, both never-smokers and daily smokers. Believing that smoking controls weight, exposure to thinness-depicting media, and low levels of skepticism about tobacco advertising were associated with being a smoker. Among smokers, believing that smoking controls weight, internalizing thinness pressures, and low levels of feminist consciousness were associated with smoking for weight control. Results are discussed with the aim of encouraging public health anti-smoking campaigns targeted at women, and smoking cessation programs that are responsive to the needs of weight-concerned female smokers.  相似文献

The present study was concerned with Wason's THOG problem, a hypothetico-deductive reasoning task for which performance over the past 20 years has typically been very poor (<20% correct). We examined the hypothesis that incorporating a quasi-visual context into the problem statement would make both the binary, symmetric tree structure and solution principle of the THOG task clearer and thus facilitate performance. A version of O'Brien et al.'s (Q J Exp Psychol 42A:329–351) Blackboard THOG problem, that specifies each branch of the tree by describing a specific location for each possible color-shape combination, was used to test this hypothesis. Substantial facilitation was both observed (68% correct) and replicated (73% correct), and it was also shown that it is necessary to provide a representation of both sides of the tree to obtain this level of facilitation. The implications of these results for human deductive reasoning are considered. Received: 1 November 2000 / Accepted: 4 May 2001  相似文献

This study examined the nature of verb deficits in 14 individuals with probable Alzheimer's Disease (PrAD) and nine with agrammatic aphasia. Production was tested, controlling both semantic and syntactic features of verbs, using noun and verb naming, sentence completion, and narrative tasks. Noun and verb comprehension and a grammaticality judgment task also were administered. Results showed that while both PrAD and agrammatic subjects showed impaired verb naming, the syntactic features of verbs (i.e., argument structure) influenced agrammatic, but not Alzheimer's disease patients' verb production ability. That is, agrammatic patients showed progressively greater difficulty with verbs associated with more arguments, as has been shown in previous studies (e.g., Kim & Thompson, 2000; Thompson, 2003; Thompson, Lange, Schneider, & Shapiro, 1997), and suggest a syntactic basis for verb production deficits in agrammatism. Conversely, the semantic complexity of verbs affected PrAD, but not agrammatic, patients' performance, suggesting "bottom-up" breakdown in their verb lexicon, paralleling that of nouns, resulting from the degradation or loss of semantic features of verbs.  相似文献

Prior research on age and emotions has found that older adults may show better physiological regulation to stressful stimuli than do younger adults. However, the stress reactivity literature has shown that age is associated with higher cardiovascular reactivity to laboratory stress (J. R. Jennings et al., 1997). The authors investigated these conflicting findings further by examining daily ambulatory blood pressure in 428 middle-aged to older adults. Consistent with the age and reactivity literature, relatively old individuals showed significantly greater increases in ambulatory diastolic blood pressure compared with younger individuals when dealing with daily stressors. However, results also revealed that relatively old individuals reported less of an increase in negative affect during daily stress compared with their younger counterparts. The results of this study are consistent with the age-related increase in cardiovascular risk but highlight the complex links between stress and different facets of the aging process.  相似文献

A blind man (E.A.) was asked to draw pictures suggesting wheels in various kinds of motion. Six pictures were drawn by E.A. The pictures were shown to sighted subjects, who were asked to assign labels to the pictures, in a multiple-choice format. The labels were assigned at a rate above chance. We argue that the pictures are metaphoric and that pictorial metaphor relies on common properties of the static picture and the kinetic referent.  相似文献

The Ss made judgments of the frontoparallel plane monocularly and binocularly by adjusting the position of a rotatable thin luminous line viewed in darkness. The judgments were made before and after a 10-min period of monocular inspection of a luminous outline frontoparallel trapezoid which was the projection of a rectangle rotated in depth. Verbal reports indicated normalization of perspectival slant depth, i.e., the inspection figure appeared less rotated, and the line settings exhibited an aftereffect bf normalization. These findings may contribute toward an account of certain previously unexplained observations reported in an earlier study by Epstein and Morgan-Paap (1974) dealing with adaptation to uniocular image magnification.  相似文献

A questionnaire about thoughts and ideas during sexual activity was returned by 51 females and 50 males in a random sample of college undergraduates. A high response rate (91%) and the similar sexual experience of male and female respondents make possible a strong conclusion about the college population sampled: Males are thinking more about past experiences and current behavior, while females are thinking more of imaginary experiences. This difference occurs for thoughts during masturbation as well as for thoughts during heterosexual activity. It appears that females prefer a different kind of sexual fantasy than males, rather than being generally less interested in sexual fantasy as claimed by Kinsey, Pomeroy, Martin, and Gebhart (Sexual behavior in the human female, Philadelphia: Saunders, 1953).  相似文献
