Purpose
Regulatory focus is a crucial self-regulation variable that influences employee workplace behavior. However, research findings to date have been equivocal with respect to the relation of prevention focus with counterproductive work behavior (CWB). On the one hand, prevention focus sensitizes people to experience high activation negative emotions. Such emotions prompt aggressive behavior, suggesting a positive relation of prevention focus with CWB through this affective route. On the other hand, prevention focus also sensitizes people to fulfill obligations and abide by rules. Such obligations align employee behavior with organizational norms, suggesting a negative relation of prevention focus with CWB through this cognitive route. To better understand the nature of this prevention focus–CWB relationship, we examined these underlying affective and cognitive mechanisms simultaneously in two multi-wave studies.Methodology and Findings
In study 1, data were collected from 151 full-time employees across two time points, and the results showed that prevention focus was positively related to both deviant behavior and withdrawal. In study 2, data were collected from 199 full-time employees across four time points, and we found that prevention focus has a significant negative indirect effect on withdrawal via felt obligation. We discuss the theoretical and practical implications of our findings for the regulatory focus and CWB literatures.882.

We evaluated the effect of posting caloric information on food purchases at a cafeteria. Purchases of more than 14,300 entrees, vegetables, and salads by 6,970 customers were unobtrusively monitored via the cash register inventory control system during 15 evening observations. A quasi-multiple-baseline design across food groups was used to test the additive effect of labeling the three lowest caloric choices for vegetables, salads, and entrees. A linear logit analysis confirmed that labeling increased the probability of low calorie selections for vegetables and salads, but not for entrees. Observations of meals purchased by a subsample of 413 customers indicated labeling did not change the total caloric content of meals. The number of customers and total sales per evening were unaffected by the labeling intervention. The results suggest that manipulating environmental cues may be an effective method for changing food purchases in a cafeteria, but labeling individual items may not be the best way to decrease total calories purchased. 相似文献

A growing body of evidence suggests that people with bipolar disorder are highly goal-oriented. Compared to other persons, they expend more effort to attain rewards and view goal pursuit as more important to their self-worth. Persons at risk for mania and those diagnosed with bipolar spectrum disorders have been shown to endorse highly ambitious life goals, such as becoming a multimillionaire or achieving fame. This study is the first examination of whether such elevated goals characterize persons diagnosed with bipolar I disorder. We also examined whether elevated ambitions predicted symptom change over time. Ninety-two persons with bipolar I disorder and 81 age- and sex-matched controls completed the Willingly Approached Set of Statistically Unlikely Pursuits, a measure of extremely high life ambitions. A subset of the bipolar participants completed a 3-month follow-up interview. Participants with bipolar disorder endorsed higher ambitions for popular fame than did controls; moreover, heightened ambitions for popular fame and financial success predicted increases in manic symptoms in those with bipolar disorder over the next three months. Discussion focuses on goal regulation in bipolar disorder. 相似文献

Social comparisons are important because other people can serve as benchmarks to determine one's own capabilities and act as sources for inspiration. Despite this, people do not always fully utilize social comparison information. The present paper demonstrates that feelings of power may reduce use of social comparison information. In three experiments, participants were first induced to feel high or low in power, or were in a control condition. Then, they were exposed to either upward or downward comparison targets. In all three experiments, low power participants responded to targets with contrast or assimilation, whereas high power participants did not. This has important implications for our understanding of how people's positions in the social and organizational hierarchies affect their basic psychological functioning. 相似文献

This study aimed to develop predictive models for real-life driving outcomes in older drivers. Demographics, driving history, on-road driving errors, and performance on visual, motor, and neuropsychological test scores at baseline were assessed in 100 older drivers (ages 65-89 years [72.7]). These variables were used to predict time to driving cessation, first moving violation, or crash. Using Cox proportional hazards regression models, significant individual predictors for driving cessation were greater age and poorer scores on Near Visual Acuity, Contrast Sensitivity, Useful Field of View, Judgment of Line Orientation, Trail Making Test-Part A, Benton Visual Retention Test, Grooved Pegboard, and a composite index of overall cognitive ability. Greater weekly mileage, higher education, and "serious" on-road errors predicted moving violations. Poorer scores from Trail Making Test-Part B or Trail Making Test (B-A) and serious on-road errors predicted crashes. Multivariate models using "off-road" predictors revealed (a) age and Contrast Sensitivity as best predictors for driving cessation; (b) education, weekly mileage, and Auditory Verbal Learning Task-Recall for moving violations; and (c) education, number of crashes over the past year, Auditory Verbal Learning Task-Recall, and Trail Making Test (B-A) for crashes. Diminished visual, motor, and cognitive abilities in older drivers can be easily and noninvasively monitored with standardized off-road tests, and performances on these measures predict involvement in motor vehicle crashes and driving cessation, even in the absence of a neurological disorder.

People are motivated to defend and rationalize the status quo, a phenomenon known as system justification. We propose the existence of a second, countervailing system-level motivation: system-change motivation, which is concerned with bettering the status quo over time. The opportunity to receive diagnostic information about the status quo pits the two system-level motives against each other. Whereas system justification promotes a preference for positive information about the status quo, system-change motivation promotes a preference for negative information about the status quo. In three experiments, we found that people preferred negative over positive feedback about the status quo when it was presented as being changeable. Our findings are the first to suggest the operation of a system-change motive. 相似文献
