This article uses meta-analysis to summarize previous empirical studies which examine the relationship between actual income/pay satisfaction and organizational commitment (OC) across different structural settings. Twenty-one studies with correlational data on the relationship between OC and income, and 27 studies dealing with OC and pay satisfaction are examined; these studies include 23 and 31 independent samples, respectively. The findings reveal a moderator effect related to type of occupation in the OC-income relationship, and to sector in the OC-pay satisfaction relationship. The findings also show the moderating effect of measurement of OC on pay satisfaction. Theoretical and methodological considerations pertaining to the OC-rewards relationship are discussed. Directions for future research and practical implications are indicated.The authors would like to thank HelenJane Shawyer and Marion Lupu for their editorial assistance.  相似文献

IMPLICIT MEMORY IN AMNESIC PATIENTS:   总被引:1,自引:0,他引:1  
Abstract— Previous observations of spared priming in amnesic patients have been based almost entirely on data from visual implicit memory tests Our research examined perceptual priming.in amnesic patients and control subjects on an auditory identification task in which previously spoken words and new words were presented in white noise We manipulated type of encoding task (semantic vs nonsemantic) and speaker's voice at study and test (same vs different) Priming was little affected.by either manipulation, and amnesic patients exhibited normal priming in all experimental conditions On an explicit test of recognition memory, by contrast, amnesic patients exhibited.severely impaired performance following the semantic study task, all subjects showed poor explicit memory following the nonsemantic study task Results are consistent with the idea that auditory priming depends largely on a presemantic auditory perceptual representation system  相似文献

Decision attitude — an analog of risk attitude — is the propensity to make (or avoid making) a decision: in decision aversion, a person finds it more desirable to receive through fiat the better of two options than to have a choice between them; in decision seeking, the choice is more desirable, even though it can lead to nothing better than the best option. Both decision aversion and decision seeking were found in hypothetical scenarios. Experimental manipulations and subjects' justifications point to anticipated regret, fear of blame for poor outcomes, and desire for equitable distributions as sources of decision aversion. One source of decision seeking (for self) and decision aversion (when deciding for others) appears to be the desire for the self-determination of the affected parties. We consider the implications of our results for personal choice and public policy decisions.  相似文献

This paper considers some of the implications of reflexivity for the practice of psychological research. After a brief consideration of the theoretical background to a concern with reflexivity, the paper goes on to examine how various researchers have attempted to incorporate components of reflexivity in their research practice. While a group of sociologists of science have operationalized reflexivity by self-conscious concern for their own role in the construction of social—scientific knowledge, new paradigm co-operative inquirers interpret a need for reflexivity by including their participants as fully self-reflexive co-researchers. Mulkay's suggestion for a dialogic analytical exchange with one's participants is also considered. The second half of the paper illustrates an attempt at reflexive practice in the authors' own research. This was a project concerned with identity change during the transition to motherhood, and aimed to allow the women a strong hand in helping to shape the project's direction. Preliminary analysis of a woman's data was taken back to her for her comments, and her reflections on the data were incorporated in the final case study. A detailed example of the investigator and participant's discussion of a piece of data is provided.  相似文献

We describe a plan for integrating an experimental control language, PsyScope, into under-graduate laboratory exercises of perceptual and cognitive experiments on Macintosh computers. PsyScope is a powerful and versatile system with which students can modify standard research paradigms and execute experiments of their own design, thus facilitating student-initiated independent research. Data are summarized with a general-purpose program, PsySquash, for import into Statview or SuperAnova for further analysis. This system provides an effective means of implementing student projects.  相似文献

In this paper, it is proposed that a) psychosocial medicine is best taught in a setting that provides technical and emotional support, while seizing for teaching only those moments when the learner is most receptive; and b) that the setting should avoid the development of a separate psychosocial skills curriculum, but should take the student where he or she is and integrate the psychosocial skills into his or her everyday biomedical practice. The paper gives specific case examples in which family based psychosocial issues were preeminent in the clinical problem-solving medical residents faced.  相似文献

Ten subjects served as their own controls in two conditions of continuous, centrifugally produced hypergravity (+2 Gz) and a 1-G control condition. Before and after exposure, open-loop measures were obtained of (1) motor control, (2) visual localization, and (3) hand-eye coordination. During exposure in the visual feedback/hypergravity condition, subjects received terminal visual error-corrective feedback from their target pointing, and in the no-visual feedback/hypergravity condition they pointed open loop. As expected, the motor control measures for both experimental conditions revealed very short lived underreaching (the muscle-loading effect) at the outset of hypergravity and an equally transient negative aftereffect on returning to 1 G. The substantial (approximately 17°) initial elevator illusion experienced in both hypergravity conditions declined over the course of the exposure period, whether or not visual feedback was provided. This effect was tentatively attributed to habituation of the otoliths. Visual feedback produced a smaller additional decrement and a postexposure negative aftereffect, possible evidence for visual recalibration. Surprisingly, the target-pointing error made during hypergravity in the no-visual-feedback condition was substantially less than that predicted by subjects’ elevator illusion. This finding calls into question the neural outflow model as a complete explanation of this illusion.  相似文献
