In this paper we explore the linkages among various types of person-organization (PO) fit and their effects on employee attitudinal outcomes. We propose and test a conceptual model which links various types of fits—objective fit, perceived fit and subjective fit—in a hierarchical order of cognitive information processing and relate them to employee organizational commitment and job satisfaction. By unveiling how the different types of fit relate to each other in influencing individual outcomes, we address some of the theoretical and methodological concerns in the use of different methods in measuring PO fit. 相似文献

Extensive research suggests that long-term potentiation (LTP) may serve as a cellular mechanism for memory and that alterations in synaptic plasticity may underlie the gross memory impairments observed in patients with Alzheimer's disease. Cholinergic facilitation of hippocampal LTP in the behaving rat is a useful model for the study of the effects of anticholinesterase or other drugs on synaptic plasticity. Field excitatory postsynaptic potentials were recorded from the hippocampal CA1 region following excitation of the basal dendrites in behaving male Long-Evans rats. LTP was induced by a high-frequency train (200 Hz for 0.5s duration) following injection of the acetylcholinesterase inhibitor eserine sulfate (0.5 mg/kg, i.p.), specific muscarinic M1 receptor antagonist pirenzepine (21.2 microg/microl, i.c.v.), or saline (i.p. or i.c.v.). Pirenzepine was found to block basal-dendritic LTP when LTP was induced during walking, but not when LTP was induced during immobility. Eserine facilitated LTP when induction occurred during either immobility or walking. The present study demonstrates that an anticholinesterase enhances LTP in CA1 of the behaving rat, and that facilitation of basal-dendritic LTP during walking is mediated by muscarinic M1 receptors. 相似文献

This study compared the cross-cultural formation and reactions toward overall fairness perception of employees from the US, China, Korea, and Japan. Distributive justice was related to overall fairness less strongly for Americans and Japanese than for Chinese and Koreans. In contrast, interactional justice was related to overall fairness more strongly for Americans and Japanese than for Chinese and Koreans. As expected, materialism seems to provide a coherent account of these cultural differences. In addition, overall fairness showed a stronger effect on turnover intention for Americans than for Chinese and Koreans. For job satisfaction, the effect of overall fairness was stronger for Americans than for Chinese, Koreans, and Japanese. Power distance seems to provide an adequate account of these cultural differences. 相似文献

Cultural assumptions about one's relation to others and one's place in the world can be literally embodied in the way one cognitively maps out one's position and motion in time and space. In three experiments, we examined the psychological perspective that Asian American and Euro-American participants embodied as they both comprehended and produced narratives and mapped out metaphors of time and space. In social situations, Euro-American participants were more likely to embody their own perspective and a sense of their own motion (rather than those of a friend), whereas Asian American participants were more likely to embody a friend's perspective and sense of motion (rather than their own). We discuss how these psychological perspectives represent the soft embodiment of culture by implicitly instantiating cultural injunctions (a) to think about how you look to others and to harmonize with them or (b) to know yourself, trust yourself, and act with confidence. 相似文献

Neuroimaging studies have shown the involvement of prefrontal and posterior parietal cortexes in regulating information processing.
We conducted behavioral and fMRI experiments to investigate the relationship between memory selection and proactive interference
(PI), using a delayed recognition task with a selection cue presented during the delay indicating which two of the four studied
digits were relevant to the present test. PI was indexed by the response time differences between rejecting probes matching
and not matching the no longer relevant digits. By varying the delay intervals, we found that the effect of PI did not diminish,
even for cases in which the postcue interval was extended to 9 sec, but was stronger when the precue interval was lengthened
to 5 sec. By examining the correlation between PI index and neural correlates of memory selection, we found that stronger
PI is predicted by lower selection-related activity in the left inferior parietal lobe, the precuneus, and the dorsal middle
frontal gyrus. Our results suggest that activity in the prefrontal-parietal network may contribute to one’s ability to focus
on the task-relevant information and may proactively reduce PI in working memory. 相似文献

A series of experiments studied reacquisition of fear reactions to a completely extinguished context. Reacquisition was rapid when reconditioning occurred as soon as the fear reactions were completely extinguished, showing that the original conditioning was intact. However, when reconditioning occurred after massive extinction training, fear reactions were depressed but then recovered across a long retention interval. This recovery was due to reconditioning and was similar to that produced by conditioning a massively preexposed context. These results show that massive extinction converts a potentially dangerous context into one that is merely familiar. 相似文献

In this study, the romantic beliefs, styles of relating, sex-role traits, and social self-efficacy of 433 young people from three cultural groups were assessed and their links with relationship status and loneliness explored. A majority cultural group (Anglo-Australians) was compared with two minority groups (Chinese- and Southern European-background young people) within the same society. Chinese-background youth were less likely to be in a romantic relationship and more likely to be lonely than Anglo-Australian or Southern European-Australians. Greater loneliness was associated with non-secure relationship styles, lower social self-efficacy, and lower scores on psychosocial femininity and masculinity. Predictors of relationship status included romantic attitudes and relationship styles. Some evidence pointed to stronger social efficacy and more secure relationship styles being associated with greater acculturation but it was rather weak and inconsistent. 相似文献

This study was designed to examine the links between the personality of group members and their styles of communication in task groups meeting over a three-month period. Comprehensive measures of personality and of communication styles were taken from the perspectives both of the actor (the self) at the beginning of the group's life and his or her fellow group members (the others) at the end of the group's life. Even after extensive group interaction, these two sets of ratings converged only when observable characteristics were being measured (e.g., extraversion in personality or precision in communication). Self-rated personality across eight dimensions predicted two of the three self-rated dimensions of communication style (Verbal Engagement and Attentiveness to the Other) at only moderate levels; the actor's personality rated on the same eight dimensions by others predicted the actor's communication style as rated by these same others on all three dimensions (Verbal Engagement, Attentiveness to the Other, and Feelings versus Silence), and at much stronger levels than did self-ratings of personality. Both personality and communication styles as rated by others were able to predict the key social outcomes of the actor's likability and task contribution, whereas self-ratings were not. Ratings derived from the self and those derived from others about the self thus appear to develop from different sources of information and relate to different outcomes. The links between personality and communication style are largely confined to the perspective (self versus other) from which they were measured. 相似文献

The Catholic Church could not compromise with Communist states due to ideological incompatibility between atheist Marxism-Leninism and religious beliefs. Christianity, in the perception of the Chinese Communist Party (CCP), had been closely linked with "foreign cultural imperialism". This study examines the clash of authority between the CCP and Catholic Church over seminary training, elucidating the CCP's desire to retain institutional and ideological control over this particular sector of Chinese society. The findings highlight the ideological conflict between the dialectic materialism of the CCP, combined with the economic materialism (i.e., to get rich is glorious) mentality of the Deng Xiaoping-Jiang Zemin era, and religious idealism. 相似文献

This study aimed to examine the psychological adaptation of overseas and migrant students, and Anglo‐Australian students, in the light of various individual variables including social self‐efficacy, locus of control, loneliness, age, sex, and acculturating group membership. Participants were 382 students attending various universities in Melbourne, Australia. There were 189 Anglo‐Australian students, 72 Southern‐European second‐generation migrant students, 33 Asian migrant students, 33 Chinese migrant students, and 55 Chinese overseas students. The results suggested that there were ethnic differences in loneliness, social self‐efficacy, locus of control, and academic satisfaction. For nonmigrant students, a sense of control was important to their psychological and academic adaptation whereas for migrant/overseas students, supportive social relationships were important for their psychological and academic adaptation. The implications of these results for service provisions to students were also discussed. 相似文献
