Reductions in dietary fat have been recommended in the prevention of coronary heart disease. Because entrees contribute substantially to total meal fat content, we evaluated a cafeteria-based intervention for increasing the purchase rate of low-fat entrees (M = 6.83 g) relative to nonlowfat entrees (M = 25.59 g). The intervention included a poster listing the benefits of a LF diet and the daily LF entrees (i.e., broiled or baked chicken and fish dishes). During 6 days per phase, food selections (N = 3,264) were monitored by trained observers. The intervention, which cost $80.00, produced significant increases (i.e., from 20% to 35%) in the purchase rate of LF entrees. 相似文献

This research examined observers' reactions to sexual assault victims engaging in different forms of self-attributed responsibility. Theory and research suggests that behavioral responsibility contributes positively to the coping process of victims, whereas characterological responsibility impedes it. For observers in the present study, the expression of either type of self-responsibility by a rape victim resulted in a more negative impression of the victim's emotional well-being and greater attribution of responsibility to the victim in comparison to a victim relying solely on chance explanations. Moreover, this bias was evident among rape crisis counselors as well as lay observers. Discussion considered the implications of such biased perceptions for sexual assault victims and the need for a fuller understanding of the nature of self-attributions of responsibility by victims. 相似文献

On the role of competing word units in visual word recognition: the neighborhood frequency effect 总被引:3,自引:0,他引:3
Current models of word recognition generally assume that word units orthographically similar to a stimulus word are involved in the visual recognition of this word. We refer to this set of orthographically similar words as an orthographic neighborhood. Two experiments are presented that investigate the ways in which the composition of this neighborhood can affect word recognition. The data indicate that the presence in the neighborhood of at least one unit of higher frequency than the stimulus word itself results in interference in stimulus word processing. Lexical decision latencies (Experiment 1) and gaze durations (Experiment 2) to words with one neighbor of higher frequency were significantly longer than to words without a more frequent neighbor. This neighborhood frequency effect is discussed in terms of the different types of candidate selection process postulated by contemporary models of visual word recognition. 相似文献

In spite of a sizable body of research on the effects of information promotions on health knowledge and health behavior, relatively little is known about how such efforts affect change (or why they do not). This paper addresses that problem by exploring the particular role that health locus of control (HLC) beliefs play in individual responses to health promotion efforts aimed at encouraging preventive health behaviors. Two field experiments are presented. The first experiment examined the extent to which HLC beliefs are related to differences in individual levels of health knowledge following the distribution of an informational booklet on health. Internals high on health value who received the information booklet demonstrated greater health knowledge three months later than did other subjects, although this difference was greater among men than among women. The second experiment explored how HLC beliefs interact with differently framed “control” messages to promote behavior change in breast self-examination (BSE). HLC beliefs interacted with the control language of the BSE promotional message and a neutral reminder to affect subsequent BSE practice. Together, these studies suggest a more influential role for health locus of control beliefs in shaping responses to health messages than has previously been documented in field settings. 相似文献

The impact of mothers' gender-role stereotypic beliefs on mothers' and children's ability perceptions. 总被引:1,自引:0,他引:1
The focus of this study is the relation between mothers' gender stereotypic beliefs, their perceptions of their children's abilities, and their children's self-perceptions in 3 activity domains. Approximately 1,500 mothers and their 11- to 12-year-old children responded to questions about the children's abilities in the math, sports, and social domains. It was predicted that mothers' beliefs about their children would be moderated by their gender stereotypic beliefs about the abilities of female and male people in general. As predicted, path analyses revealed that mothers' gender stereotypic beliefs interact with the sex of their child to influence their perceptions of the child's abilities. Mothers' perceptions, in turn, mediate the influence of past performance on children's self-perceptions in each domain. 相似文献

This article presents a large-scale study that collected word identification thresholds and errors in the fragmentation task for all four-letter French words. In the first part of this article, we identify some of the variables (e.g., word frequency, neighborhood size, letter confusability) that affect performance in the fragmentation task. In the second part, we analyze individual response performance and identify different response strategies. We demonstrate that the interactive activation model can account for individual response strategies by adapting two of its original parameters: word-letter feedback and letter-word inhibition. In the third part, we demonstrate that the adaptation of the interactive activation model to the fragmentation task makes it possible to successfully simulate a facilitatory frequency effect on identification thresholds, an inhibitory neighborhood size effect on error rates, and an inhibitory letter confusability effect on identification thresholds. When the task-specific processes of the fragmentation task are specified and individual response strategies are considered, the interactive activation model provides a parsimonious architecture for modeling the task-independent processes involved in word perception. 相似文献
