青少年问题性社交网络使用是世界范围内受到普遍关注的问题。问题性社交网络使用常被称作“社交网络成瘾”、“病理性社交网络使用”或“社交网络过度使用”, 概念和界定标准还没有达成一致看法。青少年合理的社交网络使用对促进社交关系的建立、维持和发展有积极意义, 但问题性社交网络使用却对青少年的身心发展产生消极影响。对青少年问题性社交网络使用发生机制的探讨, 将为问题性社交网络的干预引导提供依据。未来的研究应对问题性社交网络使用的概念和界定标准进行澄清, 用多维视角的方法开展问题性社交网络使用发生机制的深入研究, 加强对问题性社交网络使用的理论建构和干预研究。  相似文献

亲社会名声是行动者获得的亲社会特质声誉, 它有益于行动者的社会适应。行动者首先通过亲社会行为建立亲社会名声, 亲社会名声又通过间接互惠和同伴选择过程对行动者产生外在激励作用, 通过自我概念对行动者产生内在激励作用, 进而促进其亲社会行为。行动者的贫富水平、亲社会行为的公开性、自我获益和宣传方式影响其亲社会名声的获得。未来研究应关注亲社会行为与亲社会名声之间的相互促进过程, 探索行动者亲社会行为的代价与获益如何交互影响其亲社会名声; 行动者的社会阶层如何通过对人们预期的影响而调节行动者的亲社会名声; 亲社会名声促进亲社会行为的内在机制与边界条件。  相似文献

In 2 studies, we tested what we considered to be the core of Procter and Gamble? (P&G?) latest branding strategy: making the association between its corporate brand and its product brands explicit. Participants were randomly assigned to one of the conditions: explicit association between P&G? and one of its product brands and a control condition. Results from Study 1 showed a positive influence of the corporate brand on judgements of brand quality for Crest?. Similarly, results from Study 2 showed a positive influence of the corporate brand on judgements of brand quality and trust for Oral‐B?. From a multidisciplinary perspective, we discussed the theoretical and applied implications of our results.  相似文献

Heath, Weiler, Marriott, Elliott, and Binstead (2011 Heath, M., Weiler, J., Marriott, K. A., Elliott, D., &; Binstead, G. (2011). Revisiting Fitts and Peterson (1964): Width and Amplitude manipulations to the reaching environment elicit dissociable movement times. Canadian Journal of Experimental Psychology, 65, 259268.1.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and Heath, Samani, Tremblay, and Elliott (2016 Heath, M., Samani, A., Tremblay, L., &; Elliott, D. (2016). Fitts' theorem in oculomotor control: Dissociable movement times for amplitude and width manipulations. Journal of Motor Behavior, 48, 489499.[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]) have claimed that there are dissociable movement times for amplitude and width manipulations in the Fitts' paradigm. This may to some extent be true, but the Heath et al. (2011 Heath, M., Weiler, J., Marriott, K. A., Elliott, D., &; Binstead, G. (2011). Revisiting Fitts and Peterson (1964): Width and Amplitude manipulations to the reaching environment elicit dissociable movement times. Canadian Journal of Experimental Psychology, 65, 259268.1.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and Heath et al. (2016 Heath, M., Samani, A., Tremblay, L., &; Elliott, D. (2016). Fitts' theorem in oculomotor control: Dissociable movement times for amplitude and width manipulations. Journal of Motor Behavior, 48, 489499.[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]) data do not support that contention, as shown in this comment. It is shown that data from the research of Heath et al. is not in the range of index of difficulty where ongoing visual control would be used and hence their fits of data to Fitts' law are spurious. The data of Heath et al. (2011 Heath, M., Weiler, J., Marriott, K. A., Elliott, D., &; Binstead, G. (2011). Revisiting Fitts and Peterson (1964): Width and Amplitude manipulations to the reaching environment elicit dissociable movement times. Canadian Journal of Experimental Psychology, 65, 259268.1.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) for arm movements and for the primary eye saccade submovements of Heath et al. (2016 Heath, M., Samani, A., Tremblay, L., &; Elliott, D. (2016). Fitts' theorem in oculomotor control: Dissociable movement times for amplitude and width manipulations. Journal of Motor Behavior, 48, 489499.[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]) are well correlated by the ballistic movement time equation of Hoffmann (1981 Hoffmann, E. R. (1981). An ergonomic approach to predetermined motion time systems. Proceedings of the 9th National Conference of the Institute of Industrial Engineers, Australia, 3047. [Google Scholar]) and Gan and Hoffmann (1988 Gan, K.-C. &; Hoffmann, E. R. (1988). Geometrical conditions for ballistic and visually controlled movements. Ergonomics, 31, 829839.[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]). When the ballistic equation is used to model data for constant amplitude and constant target width conditions, the effects of the amplitude and width manipulations disappear. Other research indicates that the independent effects of movement amplitude occur due to changes in the time for the distance-covering phase of the movement.  相似文献

By defining the essence of a policy problem, an issue frame shapes how individuals think about a political issue. In this research, we investigate framing effects among domain experts, an understudied yet increasingly important set of individuals in the policymaking process. Because domain experts have extensive and highly structured knowledge on a particular topic, they are likely to actively process issue frames to which they are exposed. Consequently, we hypothesize that frames consistent with experts' values will be particularly influential, whereas frames inconsistent with their values will lead to contrast effects. We test our hypotheses on a unique set of domain experts by examining professional farmers' attitudes toward no‐till agriculture. Using an experimental design, we find evidence that environmental values interact with frames to influence farmers' interest in no‐till, especially when farmers are exposed to a novel frame.  相似文献

A number of studies report that frequency is a poor predictor of acceptability, in particular at the lower end of the frequency spectrum. Because acceptability judgments provide a substantial part of the empirical foundation of dominant linguistic traditions, understanding how acceptability relates to frequency, one of the most robust predictors of human performance, is crucial. The relation between low frequency and acceptability is investigated using corpus‐ and behavioral data on the distribution of infinitival and finite that‐complements in Polish. Polish verbs exhibit substantial subordination variation and for the majority of verbs taking an infinitival complement, the that‐complement occurs with low frequency (<0.66 ipm). These low‐frequency that‐clauses, in turn, exhibit large differences in how acceptable they are to native speakers. It is argued that acceptability judgments are based on configurations of internally structured exemplars, the acceptability of which cannot reliably be assessed until sufficient evidence about the core component has accumulated.  相似文献

Across a wide variety of situations, exposure to anchors has been shown to bias people's estimates. What is not known, however, is whether externally provided anchors influence the confidence that people have in their estimates. Our studies had two goals. First, we tested whether exposure to anchors influenced people's subjective confidence levels (Studies 1 and 2). These studies revealed that people who made estimates after making comparisons with externally provided anchors tended to be more confident in their estimates than people who did not see anchors. The second goal was to test two explanations as to why anchors increase people's confidence. In Study 3, we tested the explanation that anchors increase confidence because participants thought the anchors provided useful information. In Study 4, we tested the explanation that exposure to anchors causes people to consider a narrower range of plausible values as compared to when not exposed to anchors. Support was found only for the explanation that comparisons with anchors increase confidence because people who are exposed to anchors consider a narrower range of plausible values. Taken together, these studies reveal the powerful influence anchors can have—they not only bias estimates, but also increase people's confidence in their biased estimates.

A correlational study investigated extended contact as a strategy to improve outgroup attitudes and stereotyping and to prepare children for future contact. Additional aims were to investigate when and why the effects of extended contact occur. In particular, intergroup empathy was tested as a mediator and direct contact (i.e. cross‐group friendship) as a moderator of extended contact. Participants were Italian and immigrant elementary school children. Results showed that extended contact was associated with improved intergroup empathy, which, in turn, was associated with more positive outgroup attitudes, stereotypes and behavioural intentions. These effects were significant only among participants with a low or moderate level of direct contact. The theoretical and practical implications of findings are discussed.

A growing body of research suggests that many voters rely on facial cues from political candidates to elect their leaders. Our study proposes that having a baby face could be an asset for a political candidate in a collectivist culture. Using election bulletin photographs from Taiwan's 2004, 2008 and 2012 legislative election, we look at the extent to which a candidate's baby face is related to election outcomes. Our multilevel modelling includes the number of candidates as Level 1 units, and the number of counties in which the candidates competed as Level 2 units. Vote share is the outcome variable. After considering the candidates' traits (perceived babyfacedness, competence, attractiveness and warmth) and background characteristics, babyfacedness was the strongest predictor of vote share. Results across three elections show consistent patterns: the more babyfaced the candidate, the greater the percentage of votes a candidate received, regardless of the candidate's gender, political affiliation or incumbency status. Babyfacedness is more influential than perceived competence, attractiveness and warmth.  相似文献
