The effects of locus of control on career self-management and career experiences of nonsupervisory workers were examined in different organizational environments. In organizational settings which encouraged personal initiative in career development through personnel policies and promotion practices. Internals played a more active role in their career progress than Externals by initiating their own job searches, and they had more favorable career experiences. In situations which hampered self-initiative, locus of control had little effect on career self-management and subsequent job experiences. 相似文献

Procedures were discovered for maintaining a small fixed-ratio performance under 24-hr delay in reinforcement, by appropriate manipulation of the length of delay, amount of food delivered, and size of the fixed ratio. Other experiments showed that (1) the parameters discovered in the first experiment could produce the same result without the complex history of the first procedures; (2) the same parameters of the delayed-reinforcement procedure could maintain an explicit chain of responses; (3) gradual increase in the delay in reinforcement from small to large values was not a necessary condition for achieving the major result, if large amounts of food were delivered as reinforcement and all of the behaviors were first under good control of the relevant stimuli with short delays. 相似文献

In an attempt to elucidate the nature of the subject’s strategy in a two-interval forcedchoice auditory detection task, event-related potentials were studied at two intensities which yielded mean accuracies of 82% and 98%. Subjects reported the observation interval in which they judged the signal to be present and the confidence of the judgment. Principal components varimax analyses yielded four components: a CZ maximal P300, a Slow Wave, a slow negative shift, and a late negative component. The P300 amplitude findings suggest that different strategies are utilized for high-confidence and low-confidence detections. At high confidence, P300 amplitude is large for the observation interval in which the signal is presented, indicating a strategy involving serial independent detection. However, the P300 latency findings at high confidence suggest that absence of the signal in the first observation interval is nonetheless noted: P300 latency in response to signal presence is shorter for the second observation interval than for the first observation interval. At low confidence, P300 is small or absent for both observation intervals, indicating a deferred decision, presumably arrived at through comparison of the two percepts. 相似文献

Increasingly, educators are using the World-Wide Web (the Web) and related technology to supplement their traditional teaching materials. In this paper, we present a free tool that has been placed on the Web to enable educators to create Web pages that present self-scoring quizzes. Such Web-based practice quizzes provide students with an opportunity for interactive assessment and review of course material. The tool, Quiz-o-Matic, uses active server pages to build the HTML and JavaScript code for each quiz, without requiring the user to edit any code. We present evidence that students judge the self-scoring quizzes to be useful and worthwhile additions to a course. 相似文献

A picture-word version of the Stroop task was used to test the automatic activation of psychological distance by words carrying various senses of psychological distance: temporal (tomorrow, in a year), social (friend, enemy), and hypotheticality (sure, maybe). The pictures implied depth, with the words appearing relatively close to or distant from the observer. The participants classified the spatial distance of words faster when the word's implicit psychological distance matched its spatial distance (e.g., a geographically close word was classified faster when it was "friend" than when it was "enemy"). The findings are consistent with the idea that psychological distance is accessed automatically, even when it is not directly related to people's current goals, and suggest that psychological distance is an important dimension of meaning, common to spatial distance, temporal distance, social distance, and hypotheticality. 相似文献

Maintaining a job while managing family responsibilities has become a major issue for much of today's workforce. Working couples who care both for dependent children and aging parents constitute a fast growing and understudied group called “the sandwiched generation.” Because of their multiple roles, these workers tend to be highly stressed and likely to have burnouts. The article presents the results of an exploratory study that compared 40 Israeli “sandwiched generation” couples living on a kibbutz, 80 Israeli couples living in small towns and 75 American men and women. The methodology involved a self-report questionnaire that included measures of social support, work–family conflict (WFC) and burnout. The findings revealed both cross-cultural and cross-gender differences: Americans reported higher WFC than Israelis whereas Israelis reported higher family–work conflict (FWC) than Americans. In addition, men received more support from their spouse than women with both work and family problems, Israelis received more help from their spouse with both home and work problems than Americans, and Israeli kibbutz members received more help from their spouse with both home and work problems than Israeli city dwellers. Support from the spouse for both work and home problems was found to be negatively correlated with burnout. These findings, as tentative as they are, demonstrate the theoretical and practical importance of studying “sandwiched generation” couples. 相似文献

Category learning from equivalence constraints 总被引:1,自引:1,他引:0
Information for category learning may be provided as positive or negative equivalence constraints (PEC/NEC)—indicating that
some exemplars belong to the same or different categories. To investigate categorization strategies, we studied category learning
from each type of constraint separately, using a simple rule-based task. We found that participants use PECs differently than
NECs, even when these provide the same amount of information. With informative PECs, categorization was rapid, reasonably
accurate and uniform across participants. With informative NECs, performance was rapid and highly accurate for only some participants.
When given directions, all participants reached high-performance levels with NECs, but the use of PECs remained unchanged.
These results suggest that people may use PECs intuitively, but not perfectly. In contrast, using informative NECs enables
a potentially more accurate categorization strategy, but a less natural, one which many participants initially fail to implement—even
in this simplified setting.

The association between cognitive function and mortality is of increasing interest. We followed 1870 men aged 55–69 years at cognitive assessment for 16 years to establish associations with all case and cause specific mortality. Cognitive assessment included AH4, 4 choice reaction time (used as estimates of mid-life cognition) and the National Adult Reading Test (used as an estimate of early-life cognition). Causal models were tested for the effects of a) early-life cognition, b) confounding through mid-life disease, and c) the effects of sociodemographic and lifestyle factors. A fully adjusted model was also tested. Age adjusted associations with mid-life cognitive function were found with mortality from circulatory, coronary, respiratory and digestive disease but not from cancer mortality. Age adjusted associations were attenuated and in some cases nullified by further adjustment for each of early-life cognition, mid-life disease risk and sociodemographic and lifestyle factors. These associations cannot be assumed to be unbiased estimates of effect due to the complex confounding structures that exist in these data. Future studies should explore natural experiments, use different populations where the confounding structures may be different and evaluate more complex methods that may be able to deal with the inherent complexities of a life course perspective. 相似文献

This paper builds on a recent meta-analytic review on the relationships between organizational justice and health. Specifically, we examine the moderating role of perceived organizational support (POS) on the relationships between organizational justice and three objective cardiovascular health measures, namely, heart rate, systolic blood pressure, and diastolic blood pressure, among a population of 290 public construction workers. The interaction between justice and POS was statistically significant using procedural justice, demonstrating that procedural justice is associated with improvements in the three health outcomes only when POS is relatively high. In other words, higher levels of both procedural justice and POS were needed for reduced heart rate and reduced systolic and diastolic blood pressure. However, the interaction between distributive justice and POS did not significantly relate to the health outcomes. This study makes a contribution to the field by focusing the effects of psychosocial workplace variables on measures of cardiovascular health, and demonstrating an important boundary condition of the relationships between procedural justice and cardiovascular risk factors. 相似文献
