Interactive effects of work group and organizational identification on job satisfaction and extra-role behavior 总被引:2,自引:0,他引:2

Past research has focused on the differential relationships of organizational and work group identification with attitudes and behavior. However, no systematic effort has been undertaken yet to explore interactive effects between these foci of identification. We predicted that in cases of positive overlap of identifications (i.e. high work group and organizational identification) identifications are more strongly associated with employee job satisfaction and extra-role behavior than when only one of the identifications is high—that is, the one identification augments the influence of the other. These hypotheses were tested and supported with data from two samples of bank employees (N = 358) and travel agency employees (N = 308). 相似文献

In 2 experimental studies, social indispensability and upward social comparison were contrasted as potential triggers of motivation gains of inferior group members. Using a cognitive task in a computer‐supported environment, individual work was compared with conditions that enabled upward comparison only (coaction), or both upward comparison and social indispensability (conjunctive task). Moreover, working conditions (face‐to‐face vs. anonymous) and partner‐related performance feedback (contemporaneously vs. post‐task) were manipulated as potential moderators. Results revealed motivation gains only when partner feedback was contemporaneously available. In this case, upward‐comparison effects could be demonstrated during coaction. However, when participants' contribution determined a group outcome, their motivation was additionally increased, demonstrating social indispensability effects. Finally, motivation gains were generally higher during face‐to‐face compared to anonymous work. 相似文献

Job satisfaction is predominantly measured as global attitudinal judgment which requires employees to summarize their experiences across different job situations. In contrast, experience‐based measures assess momentary thoughts and feelings of the employees in specific job situations. This paper introduces the event reconstruction method (ERM) as an efficient measure of experience‐based job satisfaction that is less invasive and less time consuming compared with traditional experience sampling methods. An initial validation study is reported with N=193 employees from a German wholesale company. As expected, job satisfaction measured with the ERM was different from attitudinal job satisfaction. Also, consistent with expectations, experience‐based job satisfaction was a better predictor of self‐reported helping behaviour, whereas attitudinal job satisfaction was a better predictor of turnover intentions. Finally, comparing the ERM results with the results of a similar study using a traditional experience sampling method ( Fisher, 2002 ) revealed very similar patterns. 相似文献

The present study examined the effects of thought suppression on sleep-onset mentation. It was hypothesized that the decrease of attentional control in the transition to sleep would lead to a rebound of a suppressed thought in hypnagogic mentation. Twenty-four young adults spent two consecutive nights in a sleep laboratory. Half of the participants were instructed to suppress a target thought, whereas the other half freely thought of anything at all. To assess target thought frequency, three different measures were used in the wake state and mentation reports were repeatedly prompted by a computer at sleep onset. In support of the hypothesis, results revealed a reversal of target thought frequency at sleep onset: Participants instructed to suppress reported fewer target thoughts than did controls before falling asleep, but more target thoughts afterwards. 相似文献

This paper analyzes the sum score based (SSB) formulation of the Rasch model, where items and sum scores of persons are considered
as factors in a logit model. After reviewing the evolution leading to the equality between their maximum likelihood estimates,
the SSB model is then discussed from the point of view of pseudo-likelihood and of misspecified models. This is then employed
to provide new insights into the origin of the known inconsistency of the difficulty parameter estimates in the Rasch model.
The main results consist of exact relationships between the estimated standard errors for both models; and, for the ability
parameters, an upper bound for the estimated standard errors of the Rasch model in terms of those for the SSB model, which
are more easily available.

Offshore orientation in marine mammals is still a mystery. For visual orientation during night-time foraging and travelling
in the open seas, seals cannot rely on distant terrestrial landmarks, and thus might use celestial cues as repeatedly shown
for nocturnally migrating birds. Although seals detect enough stars to probably allow for astronavigation, it was unclear
whether they can orient by the night sky. The widely accepted cognitive mechanism for bird night-time orientation by celestial
cues is a time-independent star compass with learned geometrical star configurations used to pinpoint north as the rotational
centre of the starry sky while there is no conclusive evidence for a time-compensated star compass or true star navigation.
Here, we present results for two harbour seals orienting in a custom made swimming planetarium. Both seals learned to highly
accurately identify a lodestar out of a pseudo-randomly oriented, realistic projection of the northern hemisphere night sky.
Providing the first evidence for star orientation capability in a marine mammal, our seals’ outstanding directional precision
would allow them to steer by following lodestars of learned star courses, a celestial orientation mechanism that has been
known to be used by Polynesian navigators but has not been considered for animals yet. 相似文献

People frequently advance political proposals in the name of a goal while remaining apparently indifferent to the fact that those proposals, if implemented, would frustrate that goal. Theorists of “deliberative democracy” purport to avoid this difficulty by arguing that deliberation is primarily about moral not empirical issues. We reject this view (the moral turn) and propose a method (The Display Test) to check whether a political utterance is best explained by the rational ignorance hypothesis or by the moral turn: the speaker must be prepared to openly acknowledge the bad consequences of his political position. If he is, the position is genuinely moral; if he is not, the position evinces either rational ignorance or posturing. We introduce deontological notions to explain when the moral turn works and when it does not. We discuss and reject possible replies, in particular the view that a moral‐political stance insensitive to consequences relies on a distribution of moral responsibility in evildoing. Finally, we show that even the most plausible candidates for the category of purely moral political proposals are best explained by the rational ignorance/posturing hypothesis, if only because enforcing morality gives rise to complex causal issues. 相似文献

In this paper we study the definability and decidability of binary predicates for time granularity in monadic languages interpreted over finitely and infinitely layered structures. We focus our attention on the equi-level (respectively equi-column) predicate constraining two time points to belong to the same layer (respectively column) and on the horizontal (respectively vertical) successor predicate relating a time point to its successor within a given layer (respectively column). We give a number of positive and negative results by reduction to/from a wide spectrum of decidable/undecidable problems. 相似文献

Two studies examined the influence of dysphoria on motivational intensity in a student sample. Participants worked on a memory
task (Study 1) or a mental concentration task (Study 2) without fixed performance standard (“do your best”). Based on their
scores on the Center for Epidemiologic Studies – Depression Scale (L. S. Radloff, 1977), dysphoric and nondysphoric students
were compared with regard to their effort-related cardiovascular reactivity during task performance. As predicted on the basis
of the mood-behavior-model (G. H. E. Gendolla, 2000) and motivational intensity theory (J. W. Brehm & E. A. Self, 1989), dysphoric
participants showed stronger cardiovascular reactivity while working on the cognitive tasks than nondysphoric participants.
In Study 1, nondysphoric participants performed better on the memory task than dysphoric participants. Theoretical implications
are discussed.
