In a sample of 117 undergraduates, helplessness scores and the discrepancy scores on a measure of perfectionism predicted depression scores, providing evidence for construct validity for the hopelessness, helplessness, and haplessness scales.  相似文献

The ability of younger and older observers to perceive surface slant was investigated in four experiments. The surfaces possessed slants of 20°, 35°, 50°, and 65°, relative to the frontoparallel plane. The observers judged the slants using either a palm board (Experiments 1, 3, and 4) or magnitude estimation (Experiment 2). In Experiments 1–3, physically slanted surfaces were used (the surfaces possessed marble, granite, pebble, and circle textures), whereas computer-generated 3-D surfaces (defined by motion parallax and binocular disparity) were utilized in Experiment 4. The results showed that the younger and older observers' performance was essentially identical with regard to accuracy. The younger and older age groups, however, differed in terms of precision in Experiments 1 and 2: The judgments of the older observers were more variable across repeated trials. When taken as a whole, the results demonstrate that older observers (at least through the age of 83 years) can effectively extract information about slant in depth from optical patterns containing texture, motion parallax, or binocular disparity.  相似文献

ABSTRACT— We investigated the hypothesis that a sociocultural variable known as the culture of honor would be uniquely predictive of school-violence indicators. Controlling for demographic characteristics associated in previous studies with violent crime among adults, we found that high-school students in culture-of-honor states were significantly more likely than high-school students in non-culture-of-honor states to report having brought a weapon to school in the past month. Using data aggregated over a 20-year period, we also found that culture-of-honor states had more than twice as many school shootings per capita as non-culture-of-honor states. The data revealed important differences between school violence and general patterns of homicide and are consistent with the view that many acts of school violence reflect retaliatory aggression springing from intensely experienced social-identity threats.  相似文献

Here we reprint, and provide background and a commentary on, a recently-rediscovered lecture by Godfrey H. Thomson entitled, “Intelligence and civilisation.” It was delivered at the University of Manchester, UK, on 23rd October, 1936, printed in 1937 in the short-lived Journal of the University of Manchester and as a pamphlet in Edinburgh. It was one in the series of lectures supported by the industrialist and philanthropist Ludwig Mond. The lecture is unusually valuable in that it places the theory, testing and practical application of intelligence against the background of the rise of fascism and its threat to civilisation. The lecture is a candid and accessible ‘confession and contemplation'; the frank thoughts of a person committed to, but critical of, intelligence testing and theory, but convinced of the power and place of intelligence differences in people's lives and in civilisation. It comes at an important time for Thomson, with regard to three of his major achievements: his Moray House Test series, the Scottish Mental Survey of 1932 (and the Northumbrian testing exercise that preceded it), and the preparation of his book The Factorial Analysis of Human Ability. The understanding of the lecture is enhanced by recently-discovered archive materials on Thomson and his circle. ([Thomson, G.H. (1937a). Intelligence and civilisation: A Ludwig Mond lecture delivered at the University of Manchester on October 23rd, 1936. Journal of the University of Manchester, 1, 18–38], from the Ludwig Mond lecture).  相似文献

Firms routinely offer warranties, often as attempts to differentiate their offerings from those of competitors. Despite this practice common to virtually every consumer durable category, extant research has been inconclusive regarding the effect of warranties on quality judgments. One potential limitation of these prior investigations is the failure to model a key element of a product warranty—consumer‐side transaction costs associated with warranty redemption. In this article, we introduce the role of consumer‐side transaction costs associated with warranty redemption and examine the joint impact of warranty length and warranty redemption costs for brand names of varying strength on consumers’ judgments of product quality. Two experiments show that warranty length signals security but not quality, and that perceived quality increases as consumers’ warranty redemption costs decrease, provided that the warranty length is short. Different dimensions or aspects of warranties have different effects on perceived quality. The implications of the results for understanding conflicting findings in the warranty‐quality literature are discussed.  相似文献

Minors (i.e., those under 18 years of age) hold a tenuous legal position in medical settings. While recent legal authority in numerous jurisdictions affords competent minors the right to consent to medical treatment, the guidelines for assessing competence are often vague or non-existent. In addition, these changes have not adequately addressed the issue of confidentiality, and it is unclear whether general practitioners (GPs) owe a duty of confidentiality to competent minors. As medical practitioners are the first point of contact in medical settings, the present study explored GPs' competence and confidentiality determinations regarding a 16-year-old female patient who presented with symptoms of an eating disorder. Questionnaires and hypothetical scenarios were sent to a sample of 1000 GPs, of which 305 responded. Results indicated that 62% of respondents would have found the patient competent, while 82% would have maintained her confidentiality. However, analysis of the rationales provided for these decisions revealed a wide discrepancy in GPs' understanding and implementation of current legal principles. This research highlights the necessity of providing GPs with clear guidelines regarding competence and confidentiality determinations when dealing with minors.  相似文献

To test social and cognitive variables that may affect the development of subjective group dynamics, the authors had 224 children between the ages of 5 and 12 years evaluate an in-group and an out-group and normative and deviant in-group members under conditions of high or low accountability to in-group peers. In-group bias and relative favorability to normative versus deviant in-group members (differential evaluation) increased when children were accountable to peers and as a function of perceptions of peer group acceptance of these members (differential inclusion). These effects were significantly larger among older children. Multiple classification ability was unrelated to judgments of group members. This study shows that the development of subjective group dynamics involves an increase in sensitivity to the normative aspects of the intergroup context.  相似文献

The publishing industry in the UK has undergone significant changes in recent years, with publishers being absorbed into conglomerates and the rise of book chains. These trends have affected the Christian book industry, with some Christian publishers coming under secular ownership and the growth of a Christian retail chain, publisher and distributor, Send the Light. Publishers that wish to sell Christian ideas through books have had to adapt to a culture where there is less explicit commitment to, or knowledge of, Christianity than in the past. Some publishers serve a Christian niche, while others, either through belonging to a powerful conglomerate or an ability to sign prominent authors, retain a presence in mainstream bookshops. Although the ownership of several Christian imprints by Rupert Murdoch and the prominence of Christian consumer products that mimic secular products are causes for concern to some, devotional works and Bible studies remain more significant sellers.  相似文献

There are data that show that women are objectified in the media, that girls and women experience a high rate of body dissatisfaction and eating problems, and that exposure to objectified media images of women is related to the experience of self-objectification and body shame among women. Media images of women promote a thin, sexy ideal. The objectification of men in the media has increased, perhaps promoting a “drive for muscularity” among boys. In the present study grade-school girls and boys ages 6 through 12 were shown four pictures of objectified images of women and men, respectively, and asked about their responses to the pictures. Although girls and boys responded equally positively to the objectified images of the people of their gender, girls showed a more consistent response to the pictures. Further, there were stronger relationships between girls' responses to the pictures, awareness and internalization of media images, and body esteem. Girls who consistently showed a rejection response to the pictures had higher body esteem than those girls who were uncertain about how to respond to the pictures. It was concluded that, perhaps due to cultural images and cultural pressures, girls more readily develop a consistent response to objectified images of women (than boys do to objectified images of men) that relates to their feelings about their own bodies.  相似文献

The present study examined and compared the effects of 2 analogues of cognitive treatments—cognitive defusion and cognitive reappraisal—on symbolically generalized avoidance established using a basic behavioral laboratory paradigm. This back‐translation design contributes to the development and validation of principle‐based definitions of the applied constructs of defusion and reappraisal. Eighty‐eight participants first underwent basic laboratory procedures designed to establish symbolically generalized avoidance in response to an arbitrary stimulus (a nonsense word). Participants were then randomized to defusion, reappraisal, or control conditions. The response variables were (a) equivalence responding—indicative of the trained relational network and analogous to the cognitive content responsible for symbolic generalization—and (b) avoidance—the behavioral impact of symbolic generalization. A between‐groups analysis revealed that defusion and reappraisal significantly increased the odds of nonavoidance responding. Discrete‐time survival mediation analyses provided preliminary support for the classification of defusion as a functional context intervention and reappraisal as a relational context intervention.  相似文献
