Drawing on theories of generalized exchange and the norm of indirect reciprocity, we conceptualize subordinates’ organizational citizenship behavior directed toward the organization (OCBO) and directed toward peers (OCBI) as antecedents of managerial trustworthy behavior and examine how managers’ affective trust in subordinates mediates this relationship. We also investigate the extent to which this mediation is moderated by the level of collectivism in a society. Data were collected from 741 managers and 2,111 subordinates in 18 countries representing all major cultural regions of the world. We find support for our hypothesized moderated mediation in that managers’ affective trust in subordinates mediates the relationships between both subordinates’ OCBO and managerial trustworthy behavior, and subordinates’ OCBI and managerial trustworthy behavior across the different countries studied. Further, managers’ affective trust in subordinates only mediates the relationships between both types of citizenship behavior and managerial trustworthy behavior when collectivism is low to medium but not when it is high. Implications for research on cross‐cultural psychology, trust, and organizational citizenship behavior are discussed.  相似文献

Theoretically, disgust sensitivity and disgust proneness could play an important role in hypochondriasis, since disgust is a defensive emotion widely believed to protect the organism from illness. However, empirical evidence to support this hypothesis has so far been based only on nonclinical samples, so that the importance and specificity of disgust for hypochondriasis remains unclear. In the current study, 36 patients with hypochondriasis, 27 with an anxiety disorder, and 29 healthy controls completed several measures which included the assessment of disgust sensitivity (Scale for the Assessment of Disgust Sensitivity) and disgust proneness (Questionnaire for the Assessment of Disgust Proneness). We found that patients with hypochondriasis and those with an anxiety disorder had higher scores than those of the healthy controls for several measures of disgust proneness. Moreover, measures of hypochondriacal characteristics were associated with those of disgust proneness and disgust sensitivity. However, no differences were found between patients with hypochondriasis and those with anxiety disorders, with respect to disgust proneness and disgust sensitivity. Therefore, it can be assumed that disgust proneness and disgust sensitivity seem to be less specific than previously suggested for the development and maintenance of hypochondriasis.  相似文献

Recent research suggests that the different components of eye movements (fixations, saccades) are not strictly separate but are interdependent processes. This argument rests on observations that gaze-step sizes yield unimodal distributions and exhibit power-law scaling, indicative of interdependent processes coordinated across timescales. The studies that produced these findings, however, employed complex tasks (visual search, scene perception). Thus, the question is whether the observed interdependence is a fundamental property of eye movements or emerges in the interplay between cognitive processes and complex visual stimuli. In this study, we used a simple eye movement task where participants moved their eyes in a prescribed sequence at several different paces. We outlined diverging predictions for this task for independence versus interdependence of fixational and saccadic fluctuations and tested these predictions by assessing the spectral properties of eye movements. We found no clear peak in the power spectrum attributable exclusively to saccadic fluctuations. Furthermore, changing the pace of the eye movement sequence yielded a global shift in scaling relations evident in the power spectrum, not just a localized shift for saccadic fluctuations. These results support the conclusion that fixations and saccades are interdependent processes.  相似文献

Biological plausibility is an essential constraint for any viable model of semantic memory. Yet, we have only the most rudimentary understanding of how the human brain conducts abstract symbolic transformations that underlie word and object meaning. Neuroscience has evolved a sophisticated arsenal of techniques for elucidating the architecture of conceptual representation. Nevertheless, theoretical convergence remains elusive. Here we describe several contrastive approaches to the organization of semantic knowledge, and in turn we offer our own perspective on two recurring questions in semantic memory research: (1) to what extent are conceptual representations mediated by sensorimotor knowledge (i.e., to what degree is semantic memory embodied)? (2) How might an embodied semantic system represent abstract concepts such as modularity, symbol, or proposition? To address these questions, we review the merits of sensorimotor (i.e., embodied) and amodal (i.e., disembodied) semantic theories and address the neurobiological constraints underlying each. We conclude that the shortcomings of both perspectives in their extreme forms necessitate a hybrid middle ground. We accordingly propose the Dynamic Multilevel Reactivation Framework—an integrative model predicated upon flexible interplay between sensorimotor and amodal symbolic representations mediated by multiple cortical hubs. We discuss applications of the dynamic multilevel reactivation framework to abstract and concrete concept representation and describe how a multidimensional conceptual topography based on emotion, sensation, and magnitude can successfully frame a semantic space containing meanings for both abstract and concrete words. The consideration of ‘abstract conceptual features’ does not diminish the role of logical and/or executive processing in activating, manipulating and using information stored in conceptual representations. Rather, it proposes that the materials upon which these processes operate necessarily combine pure sensorimotor information and higher-order cognitive dimensions involved in symbolic representation.  相似文献

Households’ resources and constraints are key components of quality of life (QOL). QOL also depends on how these are evaluated. In times of crisis one expects subjective wellbeing and quality of life to decline. We argue that the quality of life depends on objective living conditions, their subjective evaluation and the ability to maintain or improve the situation of “embedded individuals”. This ability, in turn, depends on the opportunities provided by the state, labour markets, families and communities. We analyse qualitative interviews (2008–2010) with around 25 households in precarious prosperity in two cities (Pamplona, Spain and Lausanne, Switzerland) to elaborate their QOL. Few sampled Swiss households witnessed a decline in socio-economic status, contrary to the Spanish. Domains important to these households for QOL varied according to the opportunity structures: in the Spanish sample QOL was related to the opportunities for income, work, and security to plan ahead; in the Swiss sample to health, work-life balance and loneliness. In both samples, QOL varied according to scope of agency, people’s position within the life course, the households’ past experiences, current situation and future perspectives. Lack of future perspectives and opportunities lowered QOL; reframing, adaption and accepting the situation sometimes moderated QOL. We conclude that apart from living conditions and/or subjective wellbeing, households’ agency within opportunity structures is a promising direction for further research in QOL.  相似文献

This study investigated the effects of cognitive conflict on abstract thinking. According to action‐identification theory, an ambiguous and unfamiliar situation might propel an individual to a more abstract mindset. Based on this premise, cognitive conflict was hypothesized to put people in an abstract mindset. The induced compliance paradigm, in which participants are asked to write a counter‐attitudinal essay under either low choice (producing little dissonance) or high choice (producing more dissonance), was employed. Results showed that an abstract mindset was in fact activated in the induced compliance paradigm, and this effect was more pronounced for participants having a more concrete mindset to begin with. The results suggest that the experience of cognitive conflict is closely related to increased abstraction.  相似文献

The majority of Americans identify themselves as belonging to some religious group. There is a mixed body of literature on whether or not religious affiliation has an influence on engaging in risky behaviors among young adults attending college. This study examined associations between religious affiliation, risky sexual practices, substance use, and family structure among a sample of predominantly white college females attending a southeastern university. Given the high risk of acquiring genital human papillomavirus infection as a result of high risk sexual practices, gaining a better understanding of how religious affiliation can be used to promote healthy sexual behaviors is warranted.  相似文献

According to Botvinick’s (2007) integrative account, conflict monitoring is aversive because individuals anticipate cognitive demand, whereas the revised reinforcement sensitivity theory (rRST) predicts that conflict processing is aversive because individuals anticipate aversive reinforcement of erroneous responses. Because these accounts give different reasons for the aversive aspects of conflict, we manipulated cognitive demand and the aversive reinforcement as a consequence of wrong choices in a go/no-go task. Thereby, we also aimed to investigate whether individual differences in conflict sensitivity (i.e., in trait anxiety, linked to high sensitivity of the behavioral inhibition system [trait-BIS]) represent the effects of aversive reinforcement and cognitive demand in conflict tasks. We expected that these manipulations would have effects on the frontal N2 component representing activity of the anterior cingulate cortex. Moreover, higher-trait-BIS individuals should be more sensitive than lower-trait-BIS individuals to aversive effects in conflict situations, resulting in a more negative frontal N2 for higher-trait-BIS individuals. In Study 1, with N = 104 students, and Study 2, with N = 47 students, aversive reinforcement was manipulated in three levels (within-subjects factor) and cognitive demand in two levels (between-subjects factor). The behavioral findings from the go/no-go task with noncounterbalanced reinforcement levels (Study 1) could be widely replicated in a task with counterbalanced reinforcement levels (Study 2). The frontal mean no-go N2 amplitude and the frontal no-go N2 dipole captured predicted reinforcement-related variations of conflict monitoring, indicating that the anticipation of aversive reinforcement induces variations in conflict monitoring intensity in frontal brain areas. The aversive nature of conflict was underlined by the more pronounced conflict monitoring in higher- than in lower-trait-BIS individuals.  相似文献

ABSTRACT

Prospective memory involves remembering to perform intended actions in the future. Previous work with the multinomial model of event-based prospective memory indicated that adult age-related differences in prospective-memory performance were due to the prospective (not the retrospective) component of the task (Smith & Bayen, 2006 Smith, R. E. and Bayen, U. J. 2006. The source of age differences in event-based prospective memory: A multinomial modeling approach. Journal of Experimental Psychology: Learning, Memory, and Cognition, 32: 623635. [Crossref], [PubMed], [Web of Science ®] [Google Scholar], Journal of Experimental Psychology: Learning, Memory, and Cognition, 32, 623). However, ongoing-task performance was also lower in older adults in that study. In the current study with young and older adults, the difficulty of the ongoing task was manipulated by varying the number of colors per trial to create easier and harder versions of the ongoing task for each age group. The easier version included 2 colors per trial for older adults and 4 colors for young adults. The harder version included 4 colors for older adults and 6 colors for young adults. By adjusting the ongoing-task difficulty, older adults were able to perform the ongoing task as well or better than the young adults. Analyses with the multinomial model revealed that making the ongoing task easier for older adults (or more difficult for young adults) did not eliminate age-related differences in prospective-memory performance and the underlying prospective component.  相似文献
