We examine the differential signaling impact of two low pricing policies, Price Matching Guarantees and Everyday Low Prices, on consumers' trusting beliefs and purchase intentions. We demonstrate that both PMG and EDLP pricing policies signal stores' ability to offer lower prices. However, whether these sellers were perceived as benevolent, and—consequently—consumers' purchase intentions, varied critically depending upon price uncertainty. Perceived benevolence and purchase intentions were significantly higher [lower] for sellers offering PMG than EDLP when price dispersion was high [low]. Our findings offer insights into whether and under what conditions firms should adopt these low pricing policies.  相似文献

True tool use has been documented in some bird species, but to our knowledge, it has not been shown in woodpeckers. Here, we investigated the ability of Picoides major to open nuts of Juglans mandshurica by consistently inserting walnuts between tree branches in a specific position that facilitated nut opening. As seen in these birds, we showed that woodpeckers removed 96 % of the nuts of J. mandshurica from experimental seed trays and inserted each nut in a precise position that specifically allowed nut cracking. When we inserted nuts in an alternative position, woodpeckers manipulated and repositioned nuts to allow nut opening. In contrast, when we inserted the nuts in positions preferred for nut opening, woodpeckers did not alter their position and instead opened the nuts. We suggest that the origin of this behavior, as in other forms of tool use, likely requires a higher cognitive ability in these birds.  相似文献

研究采用运动橡胶手错觉范式,操纵了“控制”和“社会效价”两个变量,通过行为实验探讨了控制和社会效价对身体拥有感的影响。结果发现,与“被动控制”条件相比,“主动控制”条件产生了更强的拥有感; 与“不利”条件相比,“有利”条件产生了更强的拥有感。且“控制”和“社会效价”的交互作用显著:无论哪种控制条件,有利条件下的拥有感都显著高于不利条件下的拥有感; 无论哪种效价条件,主动控制条件下的拥有感均显著高于被动控制条件下的拥有感。该结果表明,控制和社会效价是产生身体拥有感的条件。研究结果为提高假肢佩戴者对假肢的心理接纳程度提供了有益的训练途径。  相似文献

The social network perspective provides a valuable lens to understand the effectiveness of team leaders. In understanding leadership impact in team networks, an important question concerns the structural influence of leader centrality in advice-giving networks on team performance. Taking the inconsistent evidence for the positive relationship of network centrality and leadership effectiveness as a starting point, we suggest that the positive impact of leader centrality in advice-giving networks is contingent on team needs for leadership to meet communication and coordination challenges, which we argue are larger in larger teams. Developing our analysis, we examine the mediating role of member collaboration in the relationship of leader network centrality and team performance as moderated by team size. Based on a multi-source dataset of 542 employees and 71 team leaders, we found that leader centrality in advice-giving networks related positively to team performance in larger teams but negatively in smaller teams. Results supported the mediated moderation model via member collaboration in smaller teams, but not in larger teams.

理性认知能力与社会偏好存在紧密的关联。文章简要回顾了经济决策理论从理性模型到有限理性模型和社会偏好模型的发展进程,论述了人们理性的局限性及其根源,并进一步探讨理性认知能力与社会偏好的关系。对人类以及灵长目动物的研究显示,有限理性可能是由根源于演化的适应性机制所导致。人类不公平厌恶的起源、个体公平能力的发展规律和表征公平的大脑结构上的证据表明,理性认知能力能让人更好地抑制自私性,实现更高层次的公平。  相似文献

采用荧光PCR法对199例晚期非小细胞肺癌(NSCLC )组织进行表皮生长因子受体(EGFR )基因突变检测,分析EGFR基因突变的分布特征及其与临床病理特征的相关性。结果显示56例(28.1%)存在EGFR基因突变,其中27例(13.6%)为外显子19突变,25例(12.6%)为外显子21突变,2例为外显子18突变,1例外显子20突变,1例外显子18和20的共突变。另外,除广东及安徽省铜陵市外,辽宁地区NSCLC患者EGFR基因突变率及主要突变类型与其他地区相符,常见于外显子19、21突变,其中腺癌、不吸烟患者突变率更高,更适宜EGFR-TKI靶向治疗。  相似文献

Limited research has been conducted on dispositional mindfulness, posttraumatic stress disorder (PTSD) symptoms and academic burnout in Chinese adolescents following a tornado. The present study investigated the ways in which dispositional mindfulness is related to PTSD symptoms and academic burnout in Chinese adolescents following a tornado by considering the role of regulatory emotional self-efficacy. A total of 431 Chinese adolescents (mean age: 14.75 years) who had experienced a severe tornado 9 months prior to this study were recruited for this study. The results indicated that our model fit the data well [χ2/df = 2.774, CFI = 0.952, TLI = 0.934, RMSEA (90% CI) = 0.064 (0.051–0.077)], and revealed that regulatory emotional self-efficacy partially mediates the relationships between dispositional mindfulness and PTSD symptoms and academic burnout, respectively. The clinical implications and limitations of our research, and recommendations for future research, are discussed in this paper.  相似文献

已有工作家庭界面研究主要立足于冲突视角,近年来部分研究开始从积极视角揭示工作家庭关系的本质。工作家庭增益强调角色资源的跨界渗溢有助提升个体另一角色表现和生活品质的程度。工作家庭资源会增强个体心理资源,进而影响体验工作家庭间的跨界增益,资源的累积循环与工作家庭增益互为持续保障,跨界增益的程度受到工作家庭边界特征的调节影响。论证和提出了"角色资源累积-个体心理因素改变-跨界增益-角色评价与投入"的逻辑主线,以此构建工作家庭间角色资源跨界增益模型。  相似文献

采用眼动记录技术和恋人概念威胁启动范式探讨自我和恋人面孔优势效应的产生和维持过程。结果发现:与概念非威胁启动条件下相比,概念威胁启动条件下,被试搜索恋人面孔时的兴趣区个数和搜索自我面孔时的平均眼跳次数与搜索陌生人面孔时比差异变得不显著;恋人面孔与陌生人面孔在兴趣区内总注视时间上的差异变得不显著。结果表明,自我与恋人面孔存在注意的优先捕获和维持优势,恋人概念的威胁启动会减少对恋人的关注,证明了建立恋人的积极概念是恋人面孔优势效应产生和维持的重要原因。  相似文献
