根据社会认知理论,探讨组织情景中领导者创新性工作表现对下属创造力的影响,将领导成员交换关系和威权型领导作为情景因素,来探索它们的交互效应对下属创造力的影响。本研究采用问卷法,选取领导-下属配对数据,通过两个子研究来验证假设。研究结果显示:(1)领导创新性工作表现与下属创造力存在积极的正相关关系,创新的内在动机在其中起着中介作用;(2)威权型领导能够有效地调节这种关系;(3)领导创新性工作表现、领导成员交换关系和威权型领导对下属创造力存在三重的交互作用。最后,文章讨论了研究的局限与启示,并指出未来可能的研究方向。 相似文献

The present study examined if habit strength moderated the influence of intention on fruit consumption in a Dutch adult sample (N?=?521, 46.3% males, mean age?=?34.50, SD?=?10.87), using the theoretical relations of the Theory of Planned Behaviour (TPB). TPB variables and habit strength were assessed at baseline. Fruit consumption was assessed with a validated questionnaire five weeks later. Three groups were created: low habit strength (n?=?180), medium habit strength (n?=?185) and high habit strength (n?=?156). Confirmatory factor analyses and multi-group path analyses were performed using AMOS 4.0. A good fit was obtained for the overall measurement model and the structural models. Multi-group path analyses showed that intention was a significant predictor of fruit consumption in the low habit (β?=?0.36, p?<?0.001) and medium habit group (β?=?0.30, p?<?0.001), but a non-significant predictor in the high habit group (β?=?0.05, p?=?0.596). Implications for information-based and motivation-based interventions are discussed. 相似文献

Abstract A prospective study of 94 Dutch adults who have casual sexual partners examined whether two important aspects of safe sex, namely bringing up condom use (BCU) and actual condom use (ACU) are intentional or habitual. For each of these aspects, a model based on the Theory of Planned Behaviour (TPB: Ajzen, 1991) was pitted against a similar model that was extended with a path from past to later BCU and ACU, respectively. The results suggest that bringing up the issue of condom use was equally predicted by intentions and past BCU. However, among people with casual partners, using condoms - and more importantly not using condoms - was especially predicted by past ACU, suggesting a strong habitual component. These results are discussed in terms of their implications for safe sex education and the use of theories in safe sex promotion campaigns. 相似文献

The aim of this study was to test whether maternal smoking-specific communication and parental smoking related to smoking cognitions (i.e. attitude, self-efficacy and social norm) derived from the Theory of Planned Behaviour in association with smoking onset during preadolescence. A total of 1478 pairs of mothers and children participated (mean age: 10.11; standard deviation?=?0.78). Structural equation models in Mplus were used to examine whether smoking-specific communication influences children's smoking cognitions, which in turn, affect smoking onset. A positive association was found between pro-smoking attitudes and smoking onset. Smoking-specific communication and parental smoking were related to smoking cognitions. Specifically, frequency of communication was negatively associated with pro-smoking attitudes, social norms of mother and best friend. Quality of communication related negatively to pro-smoking attitudes and positively to self-efficacy and norms of friends. Parental smoking was positively associated with pro-smoking attitudes and norms of mother and (best) friends. Additionally, more frequent communication and higher levels of parental smoking were associated with higher smoking onset. In conclusion, smoking-specific communication and parental smoking were associated with smoking cognitions and smoking onset. Already during preadolescence, parents contribute to shaping the smoking cognitions of their children, which may be predictive of smoking later in life. 相似文献

Adolescent career development has predominantly been studied in the context of middle class Eurocentric cultures and there have been calls for greater attention to the career development of non-dominant and disadvantaged groups. Further, there have been calls to explore career development in terms of its context and process. In this regard, the need for research measures and approaches sensitive to adolescents and particular cultures has been recognised. This is particularly the case in South African career psychology. The present study used a qualitative career assessment instrument, My System of Career Influences, to explore influences on the career development of disadvantaged South African adolescents living in a children's home. Consistent with previous international and national studies, parents were shown to be an important influence. Unlike previous studies, the influence of working overseas was also identified as an important influence. The MSCI was shown to be effective in providing insight into both the context and process of career development and as a research instrument that may be used with adolescents. Recommendations for future research are made. 相似文献

ABSTRACTWhen participants search for a shape (e.g., a circle) among a set of homogenous shapes (e.g., triangles) they are subject to distraction by colour singletons that are more salient than the target. However, when participants search for a shape among heterogeneous shapes, the presence of a non-target colour singleton does not slow responses to the target. Attempts have been made to explain these results from both bottom-up and top-down perspectives. What both accounts have in common is that they do not predict the occurrence of attentional capture on typical feature search displays. Here, we present a case where manipulating selection history, rather than the displays themselves, leads to attentional capture on feature search trials. The ability to map specific colours to the target and distractor appears to be what enables resistance to capture during feature search. 相似文献

Three experiments are reported in which the relationships between task format, item type, and strategy usage were investigated for a two-dimensional relational inference task. Contrary to past findings with linear syllogisms, it was found that parallel presentation (presenting problem statements simultaneously) did not result in any increased use of deduction rule processes compared with serial presentation (presenting problem statements individually). Instead, the results suggested that mental models were used by the majority of subjects, and that multiple models were more likely to be constructed with parallel presentation. It is proposed that, in general, multiple model construction will be more frequent for deduction tasks where the cognitive load is relatively low. Hence, contrary to suggestions by Polk and Newell (1995), reasoning in this way appears to be prevalent and highly robust—where supported by task format—even where the use of this strategy is disadvantageous. 相似文献
