The importance of job autonomy, cognitive ability, and job-related skill for predicting role breadth and job performance 总被引:3,自引:0,他引:3
Role theory suggests and empirical research has found that there is considerable variation in how broadly individuals define their jobs. We investigated the theoretically meaningful yet infrequently studied relationships between incumbent job autonomy, cognitive ability, job-related skill, role breadth, and job performance. Using multiple data sources and multiple measurement occasions in a field setting, we found that job autonomy, cognitive ability, and job-related skill were positively related to role breadth, accounting for 23% of the variance in role breadth. In addition, role breadth was positively related to job performance and was found to mediate the relationship between job autonomy, cognitive ability, job-related skill, and job performance. These results add to our understanding of the factors that predict role breadth, as well as having implications for how job aspects and individual characteristics are translated into performance outcomes and the treatment of variability in incumbent reports of job tasks. 相似文献

Turnover intentions and voluntary turnover: the moderating roles of self-monitoring, locus of control, proactive personality, and risk aversion 总被引:7,自引:0,他引:7
This article explores moderators of the relationship between turnover intentions and turnover behavior to better explain why some employees translate intentions into behavior and other employees do not. Individual differences in self-monitoring, locus of control, proactive personality, and risk aversion were examined. Results indicate that self-monitoring and risk aversion moderate the intentions-turnover link. Specifically, the relationship between turnover intentions and turnover is stronger for low self-monitors and those lower in risk aversion. Locus of control moderated the relationship in 1 of 2 samples such that the relationship was stronger for those with an internal locus of control. Proactive personality, however, did not directly moderate the relationship between intentions and turnover behaviors. 相似文献

This study examined the views of 132 undergraduate students (35 men, 97 women) regarding what they considered to be contributing factors to a worthwhile or meaningful life. They rated, on a 5-point Likert scale, their agreement with each of 40 statements. Cluster analysis yielded three clusters which best described the data. One cluster comprised a religious group, and the other two clusters were nonreligious, with one having characteristics of both the religious and nonreligious cluster. 相似文献

Adult humans searched for a hidden goal in images depicting 3-dimensional rooms. Images contained either featural cues, geometric cues, or both, which could be used to determine the correct location of the goal. In Experiment 1, participants learned to use featural and geometric information equally well. However, men and women showed significant differences in their use of distant featural cues and the spontaneous encoding of geometric information when trained with features present. Transformation tests showed that participants could use either the color or the shape of the features independently to locate the goal. Experiment 2 showed that participants could use either configural or surface geometry when searching for the goal. However, their weighing of these geometric cues was dependent on initial training experience. 相似文献

Mixed amphetamine salts extended release (MAS XR; Adderall XR) and atomoxetine (Strattera) were compared in children 6 to 12 years old with attention deficit/hyperactivity disorder (ADHD) combined or hyperactive/impulsive type in a randomized, double-blind, multicenter, parallel-group, forced-dose-escalation laboratory school study. Primary efficacy measure was the SKAMP (Swanson, Kotkin, Agler, M-Flynn, and Pelham) behavioral rating scale. Changes in mean SKAMP deportment scores from baseline were significantly greater for MAS XR (n = 102) than for atomoxetine (n = 101) overall (-0.56 and -0.13, respectively; p < .0001) and at each week (p < .001). Adverse events were similar for both treatment groups. The extended time course of action and greater therapeutic efficacy of MAS XR suggests that it is more effective than atomoxetine in children with ADHD. 相似文献

The Parents Matter! Program (PMP) has developed three interventions for parents of 4th and 5th grade African-American children (9–12 years old). The overarching goal of all three interventions is to provide parents with knowledge, skills, and support for enhancing their efforts to raise healthy children. The interventions are: (1) Enhanced Communication and Parenting (five 2
-hour sessions), (2) Brief Communication and Parenting (single 2
-hour session), and (3) General Health (single 2
-hour session). This article discusses the development of these interventions, presents an overview of the content of each intervention, and discusses issues related to the facilitation/presentation of these interventions. 相似文献

This study examined the relation between elevation of the infrequency (F) scale on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and the classification of psychological disorders as chronic or acute in an outpatient mental health setting. MMPI-2 and clinician rating data at time of intake were considered for 158 adult patients from an outpatient clinic. The results indicate that elevation on the F scale is associated with more chronic disorders even after the influence of other variables, such as age and comorbidity of other disorders, is statistically accounted for These results are discussed in terms of the utility and incremental validity of including the F scale as part of diagnostic screening. 相似文献

Searching in the center: pigeons (Columba livid) encode relative distance from walls of an enclosure
Gray ER Spetch ML Kelly DM Nguyen A 《Journal of comparative psychology (Washington, D.C. : 1983)》2004,118(1):113-117
Pigeons (Columba livia) searched for food hidden in the center of a square enclosure. On occasional tests without food, the enclosure was (a) unchanged from training (control tests), (b) moved to different corners of the testing room (corner tests), or (c) doubled in size (expansion tests). The birds showed localized search in the center of the enclosure on control and corner tests. On expansion tests, some birds searched near the center of the enclosure, suggesting relative-distance encoding. Other birds searched at locations that maintained the training distance from walls, suggesting absolute-distance encoding. These results are consistent with previous studies on chicks (Gallus gallus) in similar enclosures and contrast with previous results on pigeons' responses to expansions of discrete landmark arrays. 相似文献

Adults searched for a goal in images of a rectangular environment. The goal's position was constant relative to featural and geometric cues, but the absolute position changed across trials. Participants easily learned to use the featural cues to find the target, but learning to use only geometric information was difficult. Transformation tests revealed that participants used the color and shape of distinct features to encode the goal's position. When the features at the correct and geometrically equivalent corners were removed, participants could use distant features to locate the goal. Accuracy remained above chance when a single distant feature was present, but the feature farthest from the goal yielded lower accuracy than one closer. Participants trained with features spontaneously encoded the geometric information. However, this representation did not withstand orientation transformations. 相似文献
