如何削弱产品来源国效应*—— 产品信息呈现方式的影响研究

以元认知和双系统模式的心理学理论为背景, 研究了分析式系统对来源国效应的削弱, 检验了产品信息呈现方式对来源国效应的调节作用。三个研究说明, 分析式系统的启动可以有效削弱来源国效应; 特定的产品信息呈现方式所引起的消费者信息处理不流畅性感知会激发消费者的元认知困难, 从而使他们在产品评价过程中主要依赖分析式系统, 达到削弱来源国效应的目的; 并不是所有能引起信息处理不流畅性的产品信息呈现方式都能削弱来源国效应, 过于复杂的呈现方式由于给消费者带来过多认知负荷, 反而不能成功启动分析系统, 从而无法削弱产品来源国形象对消费者产品评价的影响。     

Event memory and suggestibility in abused and neglected children: trauma-related psychopathology and cognitive functioning

This study examined event memory and suggestibility in 3- to 16-year-olds involved in forensic investigations of child maltreatment. A total of 322 children were interviewed about a play activity with an unfamiliar adult. Comprehensive measures of individual differences in trauma-related psychopathology and cognitive functioning were administered. Sexually and/or physically abused children obtained higher dissociation scores than neglected children, and sexually abused children were more likely to obtain a diagnosis of posttraumatic stress disorder than physically abused children, neglected children, and children with no substantiated abuse histories. Overall, older children and children with better cognitive functioning produced more correct information and fewer memory errors. Abuse status per se did not significantly predict children’s memory or suggestibility whether considered alone or in interaction with age. However, among highly dissociative children, more trauma symptoms were associated with greater inaccuracy, whereas trauma symptoms were not associated with increased error for children who were lower in dissociative tendencies. Implications of the findings for understanding eyewitness memory in maltreated children are discussed.     

歧视知觉对初中生的合作倾向与行为的影响

本文通过两个研究揭示歧视知觉对初中生合作倾向与行为的影响, 研究1采用问卷法对752名初中生进行为期一年的追踪, 运用潜变量交叉滞后结构方程模型分析歧视知觉与合作倾向之间的纵向预测关系; 研究2采用动态公共物品困境实验考察歧视知觉对合作行为的影响, 以及群体类型的调节作用。结果发现：(1)初中生的歧视知觉与合作倾向存在显著负相关; T1合作倾向可负向预测T2歧视知觉, T2歧视知觉可负向预测T3合作倾向; (2)在公共物品困境前三轮投资比和贡献率上, 歧视知觉和群体类型的交互效应显著; 而在后三轮仅发现歧视知觉在投资比和贡献率上的主效应, 以及群体类型在贡献率上的主效应。以上结果表明, 歧视知觉与合作倾向之间存在纵向螺旋式影响; 歧视知觉对前期合作行为的影响受到群体类型的调节, 但随着互动时间延长, 该调节作用消失。     

萌萌哒还是古灵精怪?奢侈品品牌可爱风格对消费者偏好的影响

奢侈品品牌热衷于使用可爱风格与消费者进行互动。本文以理想自我理论为基础,通过4个实验探索奢侈品品牌可爱风格类型对消费者偏好的影响机制和边界条件。实验1表明奢侈品品牌的可爱风格(婴儿图式/古灵精怪)会显著地影响消费者的品牌偏好,验证了主效应的因果链模型。实验2进一步明确了主效应的边界,结果表明品牌可爱风格对消费者偏好的影响只在奢侈品品牌的情境下才存在。实验3探索了自我监控水平对主效应的调节作用,发现对于低自我监控的个体,奢侈品品牌的可爱风格难以有效地影响品牌偏好。实验4分析了个体发展阶段对主效应的调节作用,结果表明对于成年期个体,古灵精怪可爱风格比婴儿图式可爱风格更能提高个体的奢侈品品牌偏好,对于童年期个体,婴儿图式可爱风格比古灵精怪可爱风格更易获得青睐。     

先天视觉经验缺失对颜色认知的影响：一项ERP研究

感觉与认知是否是相互独立的？本研究通过对比先天盲被试与明眼被试在进行物体颜色判断时的行为反应和神经电生理信号变化,探讨视觉经验缺失对颜色认知的影响。结果发现,先天盲被试具有一定的颜色知识,但其水平低于明眼被试;两组被试都出现了由颜色不匹配所诱发的N400效应,且都表现出左半球优势;但是盲人组的N400效应大于明眼组,盲人组的N400反应潜伏期小于明眼组。该结果说明,直接的视觉经验是颜色认知的充分条件而非必要条件。     

父母差别对待与青少年问题行为的关系：一个有调节的中介模型

通过问卷调查的方式,采用同胞不同经历问卷、关系网络问卷和问题行为量表对开封市1179名初高中学生进行研究。研究结果显示：（1）父母差别对待与外/内化问题行为呈显著正相关;同胞关系与外/内化问题行为呈显著负相关;父母差别对待和同胞关系呈显著负相关。（2）同胞关系在父母差别对待与外/内化问题行为之间起部分中介作用。（3）“父母差别对待→同胞关系→外/内化问题行为”这一中介路径的前半段受出生顺序调节;与年幼个体相比,父母差别对待对年长个体的同胞关系影响更大。出生顺序会调节父母差别对待对同胞关系的影响,提示二胎家庭要更关注年长个体的变化。     

医院重点专科发展过程阶段论

讨论医院重点专科发展过程的阶段划分及特征,对于我们在重点专科建设中正确地把握方向、恰当地评估成效和有力地予以推进都有十分重大和现实的意义。本文把医院重点专科发展过程分为科室建设、学科建设、科学建设阶段,并从功能目标、效率效益、人才队伍、场地设施、技术设备、技术特色、教学培训、科学研究、文化氛围、能级水平十个方面对各阶段的特征进行归纳描述。三个阶段各具不同内涵特征,又存在相互内在关联,具有方向性、连续性、可加速性、交叉性和包涵性等规律。     

反馈类型和反馈时间对动作技能获得的影响

基于简单直线运动任务和复杂曲线追踪任务,在运动技能获得阶段考察不同反馈类型和反馈时间对操作绩效的影响。结果发现,在复杂曲线轨迹追踪任务中,接受运动轨迹反馈的被试组比接受偏差数值反馈组的成绩更好;即时反馈和延迟反馈组的操作绩效间没有显著差异。在简单直线运动任务中,提供落点偏差的图形反馈组成绩始终优于提供“近/远”信息的文本反馈组;在练习初期,即时反馈组成绩更好。说明,反馈信息的具体-抽象程度影响被试运动技能获得,提供具体直观的轨迹/图形反馈利于运动技能获得;反馈时间对运动技能的影响因任务难度而异。     

青少年大五人格对网络成瘾的影响:家庭功能的中介作用

Longitudinal Associations between Oppositional Defiant Symptoms and Interpersonal Relationships among Chinese Children

Children with oppositional defiant disorder (ODD) are at increased risk for developing poor relationships with people around them, but the longitudinal links between ODD symptoms and subsequent interpersonal functioning remain unclear. In the current study, we examined the bidirectional associations between ODD symptoms and children’s relationships with parents, peers, and teachers. We included separate analyses for parent vs. teacher reports of ODD symptoms, with regard to subsequent interpersonal relationships. Participants included 256 children with ODD, recruited in China, along with their parents and teachers, assessed at three time points roughly two years apart. Parents and teachers reported child ODD symptoms at each time point, and children reported their perceptions of father– and mother–child attachment, peer relationships, and teacher–student relationships across the three time points. ODD symptoms reported either by parents or teachers predicted impairments in interpersonal functioning. Meanwhile, child interpersonal impairments with peers and teachers predicted subsequent increase in teacher-reported ODD symptoms. These findings highlight the importance of transactional models of influence—and of considering early intervention for ODD in protecting children from developing further deficits and impairments. Additionally, we discuss the perspectives of multiple informants on ODD symptoms, including their different patterns of association with subsequent interpersonal relationships.
