Music videos are a particularly influential, new form of mass media for adolescents, which include the depiction of scantily clad female models whose bodies epitomise the ultra-thin sociocultural ideal for young women. The present study is the first exposure experiment that examines the impact of thin models in music videos on the body dissatisfaction of 16–19-year-old adolescent girls (n = 87). First, participants completed measures of positive and negative affect, body image, and self-esteem. Under the guise of a memory experiment, they then either watched three music videos, listened to three songs (from the videos), or learned a list of words. Affect and body image were assessed afterwards. In contrast to the music listening and word-learning conditions, girls who watched the music videos reported significantly elevated scores on an adaptation of the Body Image States Scale after exposure, indicating increased body dissatisfaction. Self-esteem was not found to be a significant moderator of this relationship. Implications and future research are discussed.  相似文献

The article reviews data from animal subjects on a range of timing tasks (including fixed-interval and temporal differentiation schedules, stimulus timing, aversive conditioning, and Pavlovian methods) with respect to conformity to the two scalar properties of timing behaviour: mean accuracy and scalar (Weberian) variance. Systematic deviations were found in data from temporal differentiation schedules, timing of very short (<100 ms) or very long (>100 s) durations, effects of "task difficulty", and some special cases where circadian and interval timing seemed to interact, or where some specific durations seemed to be timed more precisely than others. Theoretical reconciliation of some of these deviations with underlying scalar timing can be achieved, but a number of problematical cases remain unexplained.  相似文献

Multielement visual tracking and visual search are 2 tasks that are held to require visual-spatial attention. The authors used the attentional operating characteristic (AOC) method to determine whether both tasks draw continuously on the same attentional resource (i.e., whether the 2 tasks are mutually exclusive). The authors found that observers can search and track within the same trial significantly better than would be predicted if the 2 tasks were mutually exclusive. In fact, the AOC for tracking and search is similar to that for tracking and auditory monitoring. The results of additional experiments support an attention-switching account for this high level of dual-task performance in which a single attentional resource is efficiently switched between the tracking and search. The results provide important constraints for architectures of visual selective attention and the mechanisms of multielement tracking.  相似文献

Transcoding between numerical systems is one of the most basic abilities acquired by children during their early school years. One important topic that requires further exploration is how mathematics proficiency can affect number transcoding. The aim of the current study was to investigate transcoding abilities (i.e., reading Arabic numerals and writing dictation) in Brazilian children with and without mathematics difficulties, focusing on different school grades. We observed that children with learning difficulties in mathematics demonstrated lower achievement in number transcoding in both early and middle elementary school. In early elementary school, difficulties were observed in both the basic numerical lexicon and the management of numerical syntax. In middle elementary school, difficulties appeared mainly in the transcoding of more complex numbers. An error analysis revealed that the children with mathematics difficulties struggled mainly with the acquisition of transcoding rules. Although we confirmed the previous evidence on the impact of working memory capacity on number transcoding, we found that it did not fully account for the observed group differences. The results are discussed in the context of a maturational lag in number transcoding ability in children with mathematics difficulties.  相似文献

Internalising the consumer culture ideals of materialism and appearance has been shown to be negatively related to adults' well‐being. Similarly, adults who strive towards these ideals for extrinsic reasons, such as to improve their image or status, have been shown to have lower levels of well‐being than those who strive towards them for intrinsic reasons, such as to help others or support healthy relationships. However, to date, there is little evidence that these links exist in children. In the present research, we use new, age‐appropriate scales to test our predictions derived from self‐determination theory that being extrinsically motivated to achieve materialistic and appearance ideals will predict their internalisation, which, in turn, will negatively predict children's well‐being. An initial pilot study found that extrinsic motives were negatively related to well‐being in a sample of 150 children aged 8–11 years but that intrinsic motives were not. In our main study, we modelled materialism and appearance as indicators of a single underlying consumer culture construct, and, in a sample of 160 youths aged 8–15 years, found support for our hypothesis that being extrinsically motivated to achieve these consumer culture ideals predicts their internalisation, which negatively predicts well‐being. We discuss the possible mechanisms involved in these processes and the implications of these findings for future research. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Consumer culture is characterized by two prominent ideals: the 'body perfect' and the material 'good life'. Although the impact of these ideals has been investigated in separate research literatures, no previous research has examined whether materialism is linked to women's responses to thin-ideal media. Data from several studies confirm that the internalization of materialistic and body-ideal values is positively linked in women. After developing a prime for materialism (N= 50), we present an experimental examination (N= 155) of the effects of priming materialism on women's responses to thin-ideal media, using multiple outcome measures of state body dissatisfaction. Priming materialism affects women's body dissatisfaction after exposure to thin media models, but differently depending on the dimension of body image measured. The two main novel findings are that (1) priming materialism heightens the centrality of appearance to women's self-concept and (2) priming materialism influences the activation of body-related self-discrepancies (BRSDs), particularly for highly materialistic women. Exposure to materialistic media has a clear influence on women's body image, with trait materialism a further vulnerability factor for negative exposure effects in response to idealized, thin media models.  相似文献

This paper analyses a case of hiring a manager who subsequently proves to be incompetent. Analysis reveals the importance of structural factors in escalation, especially politics. When these are considered, persistence emerges as both escalatory and rational. Likewise, behaviours manifest of information bias are actually logical managerial strategies and may mask political calculation. New potential escalation variables are identified including power, visibility, and organization culture. Withdrawal reflects an intricate balancing of factors including risk and opportunity. The theoretical implications of the findings are discussed.  相似文献
