We‐commerce: Exploring factors influencing online group‐buying intention in Taiwan from a conformity perspective

Group buying is a relatively new online consumption practice. Consumers negotiate product or service prices with businesses to obtain low prices or an increased number of products. This study investigates factors influencing online group‐buying intention from a conformity perspective. An online survey is used to sample 650 online group buyers in Taiwan. Structural Equation Modelling (SEM) is applied to examine the hypotheses within the theoretical framework. Analytical results indicate that social factors (online recommendations, media recommendations, and personal recommendations) positively affect social influence and online group‐buying intention. Individual factors (compliance and attention‐to‐social‐comparison‐information) positively affect social influence and conformity. Psychological factors (financial risk, performance risk, and social risk) negatively affect online group‐buying intention, and are positively correlated with social influence and conformity. Furthermore, social influence (informational influence and normative influence) are positively correlated with conformity and online group‐buying intention. Social influence and conformity are positively correlated with online group‐buying intention. Finally, implications of analytical findings are discussed.     

我是谁?——人际间多感觉刺激下的识脸错觉

识脸错觉是在人际间同步多感觉刺激下将他人面孔感知为自我面孔的一种主观体验。继Tsakiris报告了识脸错觉现象之后,研究者通过选取不同的刺激呈现方式、不同的被试,重点对被试的主观体验、行为反应两个方面进行了考察,并得到了大量新的研究成果;发现年龄、性别及内部敏感性是影响识脸错觉强度的重要因素,右侧颞顶联合区、顶内沟和枕下回的神经活动与被试主观报告的错觉体验强度相关。未来识脸错觉研究应侧重于研究策略的多样化并为生物特征识别中新模态的选择提供理论支持。此外,同步多感觉刺激技术的开发与应用将会对自我新面孔认同训练具有重要意义。     

道德感动的情绪效价特征:生理研究的证据

深入讨论道德感动的情绪效价特征,采用MP150多导生理记录仪测量个体在感动、积极、消极三种状态下心电、呼吸、皮电的自主神经系统生理心理指标并探讨其差异.结果 发现:感动状态下的皮电水平显著高于消极状态下的皮电水平,而与积极状态下的皮电水平不存在显著差异;感动、消极、积极三种状态下的心电、呼吸指标均不存在显著差异.结论:...     

知觉模糊度影响学习的延迟效应

基于迁移适当加工理论,采用连续识别任务范式,通过操纵字词和图片的模糊度来考察知觉模糊非流畅的延迟效应。结果发现：（1）模糊不流畅的材料学习判断值更低;（2） 知觉模糊程度对即时的再认成绩没有影响,但在延迟再认测试中流畅性较低的模糊材料成绩更好。该结果表明实验操纵方式所引发的编码过程和记忆测试所需的检索过程性质上相匹配,而且延迟测试时,知觉非流畅可以促进学习,说明该效应存在边界。     

大学生信任倾向与心理健康的关系：个体差异的视角

通过对203名大学生进行人际信任量表（ITS）和新版明尼苏达多相人格问卷（MMPI-2）的施测,从个体差异的角度来考察大学生信任倾向与各心理健康症状之间的关系。结果表明,MMPI-2临庆量表中的抑郁、精神衰弱、精神分裂症和社会内向性,内容量表中的焦虑、恐惧、强迫性、抑郁、怪异思维、愤怒、愤世嫉俗、反社会行为、A型行为、低自尊、社会不适、家庭问题、工作障碍、治疗反感,均与信任倾向呈负相关。此外,四类不同心理健康特征的被试在信任倾向上存在差异,适应良好型被试的信任倾向得分显著高于其他三类,适应不良型的信任倾向显著低于其他三类,精神敏感型和外向冲动型的信任倾向居中．且这两娄之间没有显薯差异。     

Developmental Trajectories of Maladaptive Perfectionism in Middle Childhood

The developmental trajectories of maladaptive perfectionism, along with their consequences and origins, were examined in middle childhood. A sample of Singaporean children and their parents (N = 302) were recruited for a longitudinal study when the children were 7 years old. Subsequent follow‐up assessments were made at ages 8, 9, and 11. A multimethod approach was adopted where parent reports, child reports, and observational data on a dyadic interaction task were obtained. Using latent class growth modeling, four distinct classes were obtained for critical self‐oriented perfectionism (SOP‐C), whereas two classes emerged for socially prescribed perfectionism (SPP). Children with high and/or increasing SOP‐C and SPP trajectories constituted 60% and 78% of the sample, respectively. For both SOP‐C and SPP, trajectories with high initial status were associated with higher internalizing and externalizing symptoms. Parental intrusiveness and negative parenting predicted high and/or increasing SOP‐C trajectories, whereas the child temperament dimension of surgency predicted high SPP trajectory. Both SOP‐C and SPP trajectories tended to co‐occur, suggesting a mutually reinforcing process. This study yields important findings that help advance current understanding of the emergence and developmental pathways of maladaptive perfectionism in children.     

联想学习与工作记忆在流体智力发展中的作用

以115名7、10、13岁儿童为研究对象,采用配对联想学习、倒序背数、字母-数字排序、图画概念和矩阵推理等测验,考察联想学习与工作记忆在流体智力发展中的作用。结果发现:联想学习与工作记忆在流体智力发展中均起着重要的作用,然而,在不同年龄上,两者对流体智力的作用并不相同。具体来说,在7岁时,联想学习对流体智力的作用显著,而工作记忆的作用不显著;到10岁和13岁时,工作记忆对流体智力的作用显著,而联想学习的作用不再显著。从效应量来看,随着年龄的增长,联想学习对流体智力的作用逐渐减小,而工作记忆的作用则逐渐增加。     

初中生的社会比较对认知与情感信任的影响

本研究旨在探讨不同友谊状态下,初中生的社会比较对认知与情感信任的影响,及两种信任在社会比较与亲密度变化关系中的中介作用。有效被试为522名(M=12.87岁, SD=0.67),开学初让被试提名一位最亲密朋友,期中考试后让其比较与该好友的成绩排名并评价对好友的认知与情感信任水平,随后重新评价该好友的亲密度。结果表明:在亲密朋友(第二次依旧为最亲密的朋友)中,向下比较的情感信任高于向上比较,社会比较不影响认知信任;在普通朋友(第二次亲密度降低的朋友)中,向上比较的认知和情感信任均高于向下比较;社会比较只通过认知信任影响亲密度变化(完全中介),即相比于向下比较,向上比较时的认知信任水平较高,从而更有利于维持友谊的亲密性。
