The authors compared job performance and receipt of disciplinary action among smoking and nonsmoking hotel employees using organizational records and observation. Although smokers and nonsmokers did not differ on 3 measures of discipline, there were significant differences on a guest relations performance dimension and a summated overall job performance measure. Smokers received higher ratings than did nonsmokers. Implications of these findings for the management of smoking behavior in the workplace are discussed. 相似文献

Presentation format and its effect on working memory 总被引:1,自引:0,他引:1
In three experiments, we examined the separate cognitive demands of processing and storage in working memory and looked at how effective the coordination was when items for storage varied in format/modality. A sentence verification task involving arithmetic facts was combined with a span task involving two to six items presented in picture, printed word, or spoken word format. The first two experiments were the same, except for the added requirement of articulation of the math sentence in Experiment 2. Experiment 3 varied the length of the span item and compared recall with recognition performance. The results showed that both spoken words and picture produced superior recall and recognition, as compared with printed words, and are consistent with Baddeley and Logie's (1999) and Mayer's (2001) models of working memory. Also, the differences in processing performance across spans varied with the difficulty of the task but showed the strongest support for the resource allocation model (Foos 1995). 相似文献

This study was carried out with three goals: (1) to determine the prevalence of suicidal ideation and suicide attempts among the homeless; (2) to determine what aspects of homelessness predict suicidality, and (3) to determine which aspects remain predictive after controlling for key covariates, such as mental illness. A sample of 330 homeless adults were interviewed. Sixty-one percent of the study sample reported suicidal ideation and 34% had attempted suicide. Fifty-six percent of the men and 78% of the women reported prior suicidal ideation, while 28 percent of the men and 57% of the women had attempted suicide. Childhood homelessness of at least 1 week without family members and periods of homelessness longer than 6 months were found to be associated with suicidal ideation. Psychiatric diagnoses were also associated with suicidality in this sample. 相似文献

Among affectively ill patients followed naturalistically for up to 14 years, 36 committed suicide, 120 attempted suicide, and 373 had no recorded suicide attempt. Comparing these three groups on clinical and intake personality revealed that suicide completed within 12 months was predicted by clinical but not personality variables, and suicide beyond 12 months was predicted by newly derived temperament factors, not clinical variables. Attempters and completers shared core characteristics: previous attempts, impulsivity, substance abuse, and psychic turmoil within a cycling/mixed bipolar disorder. Such temperament attributes as impulsivity and assertiveness were the best prospective predictors of completed suicides beyond 12 months with a sensitivity level of 74% and specificity level of 82%. 相似文献

Attachment Relationships as Predictors of Cognitive Interpretation and Response Bias in Late Adolescence 总被引:4,自引:0,他引:4
We investigated behavioural and cognitive representations of attachment style. Specifically, we sought to test continuity in attachment style and whether participants' perceptions of their attachments to parents, peers, and romantic partners would predict cognitive interpretation and responses to 12 ambiguous situation scenarios. Participants were 161 undergraduate students (17–20 years) who completed the Parental Bonding Instrument, the Attachment Style Questionnaire and the Inventory of Parent and Peer Attachment (peer subscale). Participants then indicated whether they interpreted ambiguous situations as threatening versus non-threatening and how they would respond (proactively, aggressively, or avoidantly). Regression analyses revealed that insecure parental attachments were the main predictor of participants' interpretations and their planned responses, followed by romantic attachments. Peer attachments played little role in the predictions. These results suggest that interpretation of situations and subsequent plans of action may be influenced by attachment related experiences. We discuss our findings in terms of their relevance to attachment theory and their application to our understanding of the concepts of attachment in development of interpersonal relationships. 相似文献

A Web site (http://web2-pc.uncc.edu/cogsci) has been established to support an interdisciplinary course in cognitive science. The modules include introductory reading material, interactive exercises/virtual laboratory, and pointers to existing material on the Web. Our approach to using the Web in support of instruction differs from distance learning initiatives because it is centered on an instructor and classroom experiences. The Web-based modules are used to supplement classroom lectures and provide an interdisciplinary perspective. 相似文献

Increasing evidence indicates the importance of environmental variables in explaining physical activity. This study evaluated sex differences in perception of home and neighborhood environmental support and assessed which neighborhood environmental variables were associated with reported physical activity of elderly people. A sample of 126 women (M age = 79.1 +/- 6.6 yr.) and 55 men (M age = 76.6 +/- 7.7 yr.) were healthy, community-dwelling individuals. A questionnaire about environmental variables was administered. Physical activity was assessed on the Baecke Questionnaire. Logistic regression analysis showed that Neighborhood Safety was related to total physical activity, activity in leisure time, and sport activities. Men were also likely to be more active in leisure time than women. Neighborhood Personal Safety was associated with physical activity of these elderly people, showing a potential influence of the environmental domain in physical activity. 相似文献

Contributions to this special issue of Applied & Preventive Psychology richly elucidate connections between a variety of psychological disorders and performance in a number of tasks that are used to reason about inhibitory deficits. This commentary calls attention to the different uses of the concept of inhibition – vernacular, neural, operational, and theoretical – and suggests that the term cognitive control avoids claims about dampened memory representations that are difficult to support. Central findings from the reviews are summarized; evidence concerning suppression-induced forgetting is featured and directions to foster application are discussed. 相似文献
