Little is known about the body image of non-White men living in Western countries, even though it has been suggested that they may be more at risk of body image concerns, especially if they internalize Western ideals. This study focused on identifying the main body image and appearance themes among 15 men of Chinese ancestry in Australia using semi-structured interviews and grounded theory. Moderate muscularity was the preferred ideal and height dissatisfaction was shown to be the primary concern. The majority was not invested in achieving muscularity and had a “holistic” approach to their body image that included concerns about hairstyling and clothing. In addition, the men were influenced by both Asian and Western ideals, and this included comparison targets with both Asian and Western men. Further studies are needed to assess the extent of men's body image and appearance concerns, and the role played by Asian and Western influences. 相似文献

In recent years, a revisionist process focused on logical positivism can be observed, particularly regarding Carnap’s work.
In this paper, I argue against the interpretation that Kuhn’s The Structure of Scientific Revolutions having been published in the International Encyclopedia of Unified Science, co-edited by Carnap, is evidence of the revisionist idea that Carnap “would have found Structure philosophically congenial”. I claim that Kuhn’s book, from Carnap’s point of view, is not in philosophy of science but rather
in history of science (in the context of a sharp discovery–justification distinction). It could also explain the fact that,
despite his sympathetic letters to Kuhn as editor, Carnap never refers to Kuhn’s book in his work in philosophy of science. 相似文献

Two experiments tested 3- and 5-month-old infants' sensitivity to properties of point-light displays of human gait. In Experiment 1, infants were tested for discrimination of point-light displays of a walker and a runner, which, although they differed in many ways, were equivalent with regard to the phasing of limb movements. Results revealed that 3-month-old, but not 5-month-old, infants discriminated these displays. In Experiment 2, the symmetrical phase-patterning of the runner display was perturbed by advancing two of its limbs by 25% of the gait cycle. Both 3- and 5-month-old infants discriminated the walker display from this new phase-shifted runner display. These findings suggest that 3-month-old infants respond to the absolute and relative motions within a single limb, whereas 5-month-old infants respond primarily to the relations between limbs and, in particular, to the bilateral symmetry between the limbs. 相似文献

The automatic evaluation of novel stimuli 总被引:6,自引:0,他引:6
From classic theory and research in psychology, we distill a broad theoretical statement that evaluative responding can be immediate, unintentional, implicit, stimulus based, and linked directly to approach and avoidance motives. This statement suggests that evaluative responses should be elicited by novel, nonrepresentational stimuli (e.g., abstract art, "foreign" words). We tested this hypothesis through combining the best features of relevant automatic–affect research paradigms. We first obtained explicit evaluative ratings of novel stimuli. From these, we selected normatively positive and negative stimuli to use as primes in a sequential priming paradigm. Two experiments using this paradigm demonstrated that briefly presented novel prime stimuli were evaluated automatically, as they facilitated responses to subsequently presented target stimuli of the same valence just as much as did pictures or names of real objects. A final experiment revealed that exposure to novel stimuli produces muscular predispositions to approach or avoid them. 相似文献

The authors extend recent research concerning the social costs of claiming discrimination by examining men's and women's responses to in-group and out-group targets who either blamed a failing grade on discrimination or answer quality. Although participants generally responded more negatively to targets who blamed discrimination, rather than answer quality, dislike was greatest and gender group identification was lowest when participants evaluated an in-group target. Moreover, an in-group target who claimed discrimination was perceived as avoiding personal responsibility for outcomes to a greater extent than was a similar out-group target. Perceptions that the target avoided outcome responsibility by claiming discrimination were shown to mediate the relationship between attribution type and dislike of the in-group target. The authors discuss their results in terms of intragroup processes and suggest that social costs may especially accrue for in-group members when claiming discrimination has implications for the in-group's social identity. 相似文献

This review provides an evaluation of the correlates and/or risk factors associated with disordered eating and the pursuit of muscularity among adolescent boys. One of the main conclusions is that similar factors and processes are associated with both behavioral problems. Several factors found to be consistently associated with disordered eating among boys are also similar to those found with girls. These include body mass index, negative affect, self-esteem, perfectionism, drug use, perceived pressure to lose weight from parents and peers, and participation in sports that focus on leanness. However, as many of the findings have only been verified using cross-sectional designs, prospective studies are now needed. 相似文献

Postextinction infusion of a mitogen-activated protein kinase inhibitor into the medial prefrontal cortex impairs memory of the extinction of conditioned fear 下载免费PDF全文
We investigated whether postextinction training infusion of PD098059, a selective inhibitor of mitogen-activated protein kinase (MAPK) activation, into the medial prefrontal cortex, would impair retention of extinction learning in rats. We found that immediate, but not late (2 or 4 h), postextinction infusion of PD098059 provoked a full return of conditioned freezing. These results suggest that activation of prefrontal MAPK in early stages of postextinction training participates in processes that protect against spontaneous recovery of aversive responses. 相似文献

A longitudinal study of pubertal timing and extreme body change behaviors among adolescent boys and girls 总被引:8,自引:0,他引:8
Recent studies have examined the prevalence of disordered eating and other health risk behaviors among adolescent boys and girls. However, these studies generally have not examined predictors of these behaviors, and have not embedded the investigations within a theoretical framework. This study employed a longitudinal design to evaluate the validity of a biosocial model in explaining health risk behaviors related to extreme body change strategies (disordered eating, exercise dependence, use of food supplements, steroid use) among adolescents. The participants were 430 adolescent boys (mean age = 13.33 years) and 451 adolescent girls (mean age = 13.28 years) who completed measures of pubertal timing, perceived popularity with peers, body dissatisfaction, focus on sport, involvement in competitive sport, strategies to lose weight, strategies to increase muscle, disordered eating, use of food supplements and steroids, and exercise dependence. It was found that both early and late maturing girls were at greatest risk of engaging in health risk behaviors, whereas boys demonstrated more variability in the relationship between pubertal timing and extreme body change behaviors. The results of this study provide important insights into the role of pubertal development in the adoption of extreme body change behaviors among adolescents. 相似文献

Recent studies suggest that research participants show reduced distortion of their taboo attitudes and behaviors when they take part in Internet-based procedures from outside the laboratory. We explored whether such procedures would reduce distortion in the assessment of racial bias. In Study 1, White participants who completed the study in the laboratory evaluated Black targets more favorably than White targets. This unexpected "outgroup-favoring" pattern occurred in both pencil-and-paper and Internet versions of the study, showing that modality did not produce it; but when participants worked outside the laboratory via the Internet, this pattern disappeared. Study 2 replicated the above findings and further indicated that the reduced distortion in Internet-based studies was due to the removal of the experimenter rather than removing the participants from the laboratory environment. The implications of these findings for the study of controlled processes of prejudice and the nature of Internet-based social communication are discussed. 相似文献
