Insufficient physical activity contributes to rising obesity rates. We tested one social cognitive strategy aimed at increasing physical activity in the environment. Specifically, we tested whether attentional narrowing can shift people’s perceptual representations of the environment and improve exercise behavior. Participants who adopted a narrow focus of attention, compared to participants who looked around the environment as they naturally would, perceived a target as physically closer (Studies 1, 2). In addition, narrowed attention reduced the time required to walk to a finish line and increased subjective ease of physical task performance, two markers of improved exercise (Study 2). We discuss implications of attentional strategies for perception and action in regards to health and fitness.  相似文献

Although much is known about broad societal attitudes toward poverty, less is known about how women perceive their own poverty. We sought to examine the types of self attributions low-income women make about their poverty, as well as the association of self poverty attributions to women’s mental health and upward mobility beliefs. Using close-ended questions in a community sample of 66 low-income mothers from the Midwestern United States, we found these women were most likely to attribute their poverty to issues related to having children, their romantic relationships, and structural/government blame. The least endorsed attributions for poverty were fatalistic and individualistic reasons. Attributing one’s poverty to children and structural reasons was related to greater depression, and attributing one’s poverty to romantic relationships and structural reasons was related to greater anxiety. Moreover, attributing one’s poverty to children and romantic relationships was positively related to upward mobility beliefs, whereas individualistic attributions were negatively related to upward mobility beliefs. Understanding how women view their poverty and upward mobility can help to improve interventions and policies aimed at low-income women.  相似文献

The concept of customer orientation (CO) is a focal construct in marketing and sales literature. Saxe and Weitz introduced CO to contrast the traditional high-pressure approach to sales (selling orientation). This study synthesizes empirical evidence from 1982 to 2013 to provide insight into the antecedents and consequences of both CO and selling orientation (SO). A conceptual meta-analytic model based on research into interpersonal motive models is proposed and tested using effect sizes from 126,790 salesperson survey responses to advance theory development on our understanding of how SO and CO behaviours affect organizations. Findings show that adaptive selling mediates the impact of both SO and CO which has important practical implications for hiring and training salespeople. Furthermore, this study shows that goal orientations are antecedents of SO and CO and that the impact of SO on job performance varies by customer type.  相似文献

Although researchers have explored organizational and insider targets of counterproductive work behavior (CWB), no studies to date have examined customers as targets. The current study aimed to test a model of antecedents to CWB unique to service worker experiences, including customer stressors, emotional dissonance, and emotional exhaustion. We tested our model with 438 restaurant and bar employees. Results demonstrated that customer stressors were more strongly correlated with customer-directed CWB than with interpersonal or organizational CWB, and customer stressors had direct and indirect effects on customer-directed CWB through experiences of emotional dissonance and exhaustion.  相似文献

The purpose of the authors in this pilot study was to assess the effects of an occupational therapy role-playing intervention for adolescents with Asperger's syndrome. An ABA multiple baseline single-subject design across participants was used with three adolescents to determine if a six-week intervention could increase targeted social behaviors. Data were collected over baseline, intervention, and probe phases. Three methods of analysis were used: visual inspection of graphed data, paired t tests, and a three standard deviation-band approach. Findings demonstrated that all three participants were able to increase the frequency of targeted social skill use from baseline to intervention and maintain this level at a one month probe. Differences between baseline and intervention phases for each participant reached statistical significance. Through this study the authors offer preliminary evidence that an occupational therapy role-playing intervention that is both client centered and graded can increase targeted social skill use in three adolescents with Asperger's syndrome.  相似文献

Most objectively scored tests use items with easily identifiable correct answers. When such veridical scoring keys cannot be constructed, researchers sometimes use proportion consensus scoring (PCS) to identify the best answers. To determine if PCS identifies the best answers, we scored a test using both PCS and veridical scoring. Among 353 undergraduates, regular PCS, two-stage PCS, and expert PCS all had high correlations for easy items, but no PCS methods had high correlations for difficult items. Thus, PCS cannot reliability identify the best answers to individual items. However, PCS worked well for total scores. For easy items, total scores had correlations above .99 for all PCS methods. For difficult items, expert and two-stage PCS had correlations of .92 and .82 for the 60-item test. Thus, expert and two-stage PCS can be justified (even for difficult items) if the scoring key is based upon people who truly possess some degree of expertise and if scores are summed over many items.  相似文献

While diathesis-stress models of cognitive vulnerability to depression (CVD) in childhood have been tested, few studies have included both parent- and child-reported negative life events, despite the fact that they provide unique information on events that may be relevant to depression risk in boys and girls. It was hypothesized that different types of stress may show moderation of CVD for boys and girls; specifically, we predicted that parent-reported stressors may moderate boys’ CVD, and that self-reported stress may play a more critical moderating role for girls. A community sample of 182 eight-year-olds completed measures of CVD at baseline, and child- and parent-reported measures of stress were collected at follow-up, one year later. Support for diathesis-stress models of CVD varied depending on child sex and the source of information on stress. Results highlight the importance of collecting multiple measures of stress in testing diathesis-stress models of CVD in middle childhood.  相似文献

Abstract

It has been reported that, by 1975, there were 25 million adults in America who were stepfathers and stepmothers (Roosevelt & Lofas, 1976), with a million more adults becoming stepparents each year. Thus the “stepfamily,” or “blended,” “remarried” or “reconstituted” family has become an important entity in American society.  相似文献

Three studies documented effects of marital status on perceptions of employees or prospective employees. In Experiment 1, participants rated a married female job applicant as less suitable for employment than a single counterpart. In Experiment 2, participants again perceived a female job applicant less favorably when she was married; in contrast, a male applicant was perceived more favorably when married. In Experiment 3, participants predicted that a recently married woman's job performance and dedication would decline, whereas a recently married man's dedication was predicted to rise; this difference made participants more willing to lay off the woman than the man.  相似文献

In this article, we propose a new approach to an old question: How does development affect religion‐state relations? We argue that because development increases states’ ability to effectively formulate and implement policy, it will be associated with greater state regulation of religion. This stands in contrast to predominant theories that examine development's negative impact on individual religiosity while largely overlooking the impact that development may have on state institutions. We test our theory using data drawn from over 160 countries, and demonstrate that the effect of economic development on state regulation of religion is consistently positive, substantively significant, and robust to alternative measurements and the inclusion of a broad range of controls. Statistical analysis also demonstrates that the correlation between development and state regulation of religion is primarily a result of economic development's impact on state capacity, rather than social dislocation or improved coordination by religious communities. Incorporating state capacity recasts the study of religious regulation—and suggests that economic growth is unlikely to take religion off the political agenda.  相似文献
