The purpose of the present study was to test whether or not a biodata instrument could be used to predict turnover, organizational commitment, and job performance in healthcare organizations. A criterion‐related, predictive validation strategy was used using a sample of 672 employees from two different hospitals in the southeastern United States. Supervisory ra0tings of organizational commitment and job performance were highly correlated with responses to the organizational commitment scale and the total score on the biodata instrument, respectively. Actual turnover was correlated with responses to the retention scale, although the effect size was small. Additionally, the study examined the fairness of biodata in this context as it relates to differences in performance among minority and non‐minority candidates. The findings in this study suggest that using such an instrument may provide organizations with the potential to improve organizational commitment and job performance, while reducing turnover with minimal group differences.  相似文献

Remembering to do something in the future (termed prospective memory) is distinguished from remembering information from the past (retrospective memory). Because prospective memory requires strong self-initiation, Craik (1986) predicted that age decrements should be larger in prospective than retrospective memory tasks. The aim of the present study was to assess Craik's prediction by examining the onset of age decline in two retrospective and three prospective memory tasks in the samples of young (18-30 years), young-old (61-70 years), and old-old (71-80 years) participants recruited from the local community. Results showed that although the magnitude of age effects varied across the laboratory prospective memory tasks, they were smaller than age effects in a simple three-item free recall task. Moreover, while reliable age decrements in both retrospective memory tasks of recognition and free recall were already present in the young-old group, in laboratory tasks of prospective memory they were mostly present in the old-old group only. In addition, older participants were more likely to report a retrospective than prospective memory failure as their most recent memory lapse, while the opposite pattern was present in young participants. Taken together, these findings highlight the theoretical importance of distinguishing effects of ageing on prospective and retrospective memory, and support and extend the results of a recent meta-analysis by Henry, MacLeod, Phillips, and Crawford (2004).  相似文献

Wentura and Frings (2005) reported evidence of subliminal categorical priming on a lexical decision task, using a new method of visual masking in which the prime string consisted of the prime word flanked by random consonants and random letter masks alternated with the prime string on successive refresh cycles. We investigated associative and repetition priming on lexical decision, using the same method of visual masking. Three experiments failed to show any evidence of associative priming, (1) when the prime string was fixed at 10 characters (three to six flanking letters) and (2) when the number of flanking letters were reduced or absent. In all cases, prime detection was at chance level. Strong associative priming was observed with visible unmasked primes, but the addition of flanking letters restricted priming even though prime detection was still high. With repetition priming, no priming effects were found with the repeated masked technique, and prime detection was poor but just above chance levels. We conclude that with repeated masked primes, there is effective visual masking but that associative priming and repetition priming do not occur with experiment-unique prime-target pairs. Explanations for this apparent discrepancy across priming paradigms are discussed. The priming stimuli and prime-target pairs used in this study may be downloaded as supplemental materials from mc.psychonomicjournals. org/content/supplemental.  相似文献

Using data from a longitudinal study of college students, this study assessed the relationships among the threat perceptions of realistic threat and intergroup anxiety, the ideological motives of system justification and social dominance orientation (SDO), and political conservatism. Those who had higher perceptions of realistic threat and intergroup anxiety at the end of their first year of college showed higher levels of system justification and SDO at the end of their second and third years of college, controlling for precollege expressions of each variable. Higher levels of these two ideological motives at the end of students' second and third years of college were associated with more politically conservative attitudes at the end of students' fourth year of college, again controlling for precollege expressions. These longitudinal results are discussed in terms of a model of political conservatism as motivated social cognition.  相似文献

For evenly spaced stimuli, a purely relative judgment account of unidimensional categorization performance is trivial: All that is required is knowledge of the size of stimulus difference corresponding to the width of a category. For unevenly spaced stimuli, long-term knowledge of the category structure is required. In the present article, we will argue that such knowledge does not necessitate a direct, absolute mapping between (representations of ) stimulus magnitudes and category labels. We will show that Stewart, Brown, and Chater’s (2005) relative judgment model can account for data from absolute identification experiments with uneven stimulus spacing.  相似文献

The WATCH (Wellness for African Americans Through Churches) Project was a randomized trial comparing the effectiveness of 2 strategies to promote colorectal cancer preventive behaviors among 587 African American members of 12 rural North Carolina churches. Using a 2 X 2 factorial research design, the authors compared a tailored print and video (TPV) intervention, consisting of 4 individually tailored newsletters and targeted videotapes, with a lay health advisor (LHA) intervention. Results showed that the TPV intervention significantly improved (p <.05) fruit and vegetable consumption (0.6 servings) and recreational physical activity (2.5 metabolic task equivalents per hour) and, among those 50 and older (n = 287), achieved a 15% increase in fecal occult blood testing screening (p =.08). The LHA intervention did not prove effective, possibly because of suboptimal reach and diffusion.  相似文献

Undergraduates' button presses occasionally produced points exchangeable for money. Left and right buttons were initially correlated with multiple random-ratio (RR) and random-interval (RI) components, respectively. During interruptions of the multiple schedule, students filled out sentence-completion guess sheets describing the schedules, and points were contingent upon the accuracy of guesses. To test for sensitivity to schedule contingencies, schedule components were repeatedly reversed between the two buttons. Pressing rates were consistently higher in ratio than in interval components even when feedback for guesses was discontinued, demonstrating sensitivity to the difference between ratio and interval contingencies. The question was whether this sensitivity was based directly on the contingencies or whether it was rule-governed. For two students, when multiple RR RI schedules were changed to multiple RI RI schedules, rates became low in both components of the multiple RI RI schedule; however, subsequent prevention of point deliveries for the first few responses in any component produced high rates in that component. For a third student, response rates became higher in the RI component that provided the lower rate of reinforcement. In each case, performance was inconsistent with typical effects of the respective schedules with nonhuman organisms; it was therefore plausible to conclude that the apparently contingency-governed performances were instead rule-governed.  相似文献

It is well known that women in the United States, as in most industrialized countries in the world, are protected from coronary heart disease (CHD), relative to men. It is thought that this protection is by and large due to the effects of female reproductive hormones (i.e., estrogens) on lipid and lipoprotein metabolism and blood pressure, although women's relatively low rates of cigarette smoking are also thought to play a role. However, epidemiological studies that statistically adjust for sex differences in lipids, blood pressure, and smoking status cannot explain sex differences in CHD morbidity and mortality. Also, inconsistent with a simple main-effect model of reproductive hormones are data showing elevated risk of myocardial infarction and stroke among women who use oral contraceptives. Men who are prescribed estrogens have elevated risk of CHD, and case-control studies show that male CHD patients have elevated estradiol, compared to controls. This article suggests that simple main-effect models of female protection from CHD are inadequate. It argues that reproductive hormones are important determinants of protection from CHD, in interaction with behavioral characteristics. It also demonstrates that reproductive hormones can influence behavioral characteristics and that behavioral characteristics can influence the effects of reproductive hormones on CHD risk factors.  相似文献

A hybrid training approach, composed of both computer-mediated communication on the Internet and face-to-face meetings, was implemented. The goals were to examine whether such an approach (1) could be used to extend traditional, short-term training, and (2) would be perceived as useful by the trainees. A central element of the approach was thelinchpin expert, a trainer who served as a communication bridge on the Internet between a team of trainers and a team of trainees. A coding system was developed to analyze the content of the Internet messages. Logistic regression analysis revealed that two types of content were related to the trainees’ perceptions that the messages enhanced their expertise in team problem solving: (1) outcome feedback given to a trainee about a specific activity, and (2) the sharing of conceptual information. The trainees perceived face-to-face and computer-mediated communications with the linchpin expert as being important to their development of expertise.  相似文献
