How identity related goals moderate the role of attributes in product evaluation

This research examines how identity related goals influence product evaluation. It is proposed that products are evaluated based on an attribute level to fulfill an identity related goal. Further, the positive relationship between an attribute level and product evaluation is strengthened by goal activation (the degree to which a goal occupies a consumer's thinking) and goal‐product fit (the extent to which consumers think a product is related to a particular goal). Results of three experimental studies support the above propositions. The research makes contributions in that it identifies two moderators, that is, goal activation and goal‐product fit, in the relationship between attributes ability and product evaluation. First, identity‐related goals are higher order and likely to have higher priority for consumers. However, results in this paper show that it still needs to be activated before it can exert an influence on attribute importance. Specifically, when an identity related goal (e.g., one supportive of the fair trade goal) is activated, it takes over a lower‐order goal (e.g., seek for a good taste or a good priced coffee in this case). As goal activation increases, relevant attributes become more important, and the positive relationship between an attribute level and product evaluation strengthens. Second, this paper introduces a new construct of goal‐product fit into identity‐related goals and product evaluation literature. The results of study three suggest that when goal‐product fit becomes stronger, the relevant attribute that can fulfill the goal becomes more important in the overall product evaluation.     

正念父母心:正念教养理论、机制及干预

父母教养及其对孩子的影响一直是发展心理学的一个重要主题,而正念教养(mindful parenting)则是关注如何帮助父母进行有效教养。正念教养是将一般的正念应用于亲子互动中,指父母对孩子和教养行为的有意的、此时此刻的和不评判的注意和觉知。正念教养对父母自身、孩子和亲子关系都具有积极的作用。研究者发展了两个正念教养的干预项目并通过实证研究检验这两个项目的干预效果。未来的研究可以采用更加严谨的设计并采用不同的评估方法来评估正念教养的干预效果。正念教养的作用机制也是未来研究有待进一步探讨的问题。     

Help yourself by helping others: The joint impact of group member organizational citizenship behaviors and group cohesiveness on group member objective task performance change

This paper examines how a group member's individual‐targeted citizenship behavior (OCBI) and organization‐targeted citizenship behavior (OCBO) interact with a salient group‐level contextual variable, group cohesiveness, to foster positive change for that group member, starting with job self‐efficacy change, and followed by objective task performance change. Over a span of 6 months, we engaged in multilevel, multisource, multistage data collection and surveyed 587 members in 83 work groups. Our results indicate that a group member's OCBI, in comparison with OCBO, is more positively related to his or her job self‐efficacy change. Group cohesiveness was found to attenuate the relationship between a group member's OCBI and job self‐efficacy change, and conversely, to accentuate the relationship between a group member's OCBO and job self‐efficacy change. Furthermore, a group member's job self‐efficacy change mediated the interactive effects of the group member's OCBI and group cohesiveness (as well as the group member's OCBO and group cohesiveness) on his or her objective task performance change.     

Why did adolescents have sleep problems after earthquakes? Understanding the role of traumatic exposure,fear, and PTSD

To examine the relationships between trauma exposure, fear, post‐traumatic stress disorder, and sleep problems in adolescents, 746 adolescent survivors of the 2008 Wenchuan earthquake in China were assessed at 1 year (T1) and 1.5 years (T2) after the earthquake using a trauma exposure questionnaire, a fear questionnaire, a child posttraumatic stress disorder symptom scale, and a subscale on child sleep problems. The results showed that T1 trauma exposure were not directly associated with sleep problems at T1 and T2, but played a positive role in sleep problems at both T1 and T2 indirectly through T1 posttraumatic stress disorder and T1 fear. T1 trauma exposure was also positively and indirectly associated with T2 sleep problems through T1 posttraumatic stress disorder via T1 sleep problems, or through T1 fear via the path from T1 posttraumatic stress disorder to T1 sleep problems. These findings indicated that fear and posttraumatic stress disorder 1 year after the earthquake played a mediating role in the relationship between trauma exposure at 1 year after the earthquake, and sleep problems at both 1 year and 1.5 years after the earthquake, respectively. In particular, posttraumatic stress disorder also had a multiple mediating effect in the path from trauma exposure to sleep problems via fear. Furthermore, the findings indicated that sleep problems were relatively stable between 1 and 1.5 years after an earthquake.     

工作记忆成分的年龄相关差异对算术策略运用的预测效应

采用选择/无选范式,借助工作记忆成套测验,在两位数乘法估算问题中探讨了工作记忆系统各成分对不同年龄段个体算术策略运用的预测效应。结果显示:(1)工作记忆的不同成分与年龄之间存在明显的相关。表现为,除视空模板成分外,其他各成分得分随着年龄增长而呈现上升趋势;(2)估算策略运用中,年龄与策略选择显著相关,表现为随着年龄增长,策略选择表现明显提高;(3)估算策略运用中,不同年龄个体的工作记忆不同成分和策略选择表现出不同的联系,中央执行均显示出显著的预测效应,语音环路和视空模板的预测效应均不显著。不同年龄个体的工作记忆不同成分对策略执行的预测效应均不显著。上述发现对于深刻理解工作记忆系统在算术认知策略运用中的作用机制具有重要理论含义。     

宽宏大量与睚眦必报:宽恕和报复对愤怒的降低作用

本研究通过3个实验比较宽恕和报复对愤怒的降低作用。采用假设情景的方法,实验1通过在冒犯行为之后直接启动宽恕或报复,结果显示宽恕比报复对愤怒的降低作用更好,并且对消极情绪也具有降低作用;实验2考察在不同冒犯行为意图下宽恕与报复对愤怒的降低作用,结果显示不管是有意而为还是无心之过的冒犯行为,宽恕对愤怒的降低作用均要优于报复。实验3要求被试在冒犯行为后进行宽恕或报复,结果显示宽恕和报复对愤怒均有降低作用,但是宽恕的降低效果要显著优于报复。研究显示,对于冒犯行为后的愤怒感,宽恕的降低作用优于报复。     

When Is More Better?

Abstract— We examine three determinants of the relationship between the magnitude of a stimulus and a person's subjective "value" of that stimulus: the process by which value is assessed (either by feeling or by calculation), the evaluability of the relevant magnitude variable (whether the desirability of a given level of that variable can be evaluated independently), and the mode of evaluation (whether stimuli are encountered and evaluated jointly or separately). Reliance on feeling, lack of evaluability, and separate evaluation lead to insensitivity to magnitude. An analysis invoking these factors provides a novel account for why people typically become less sensitive to changes in the magnitude of a stimulus as magnitude increases.     

骨折治疗方法与原则的最优化历程

多年来骨折治疗,新旧技术、新旧理论相互融合,相互碰撞,产生了新的理论和方法,使得临床疗效显著提高,现阶段理智的临床医生应该融汇各家之长,多方互补,对每一位骨折患者的治疗都应该按照最优化的原则进行.但是在医疗过程中总存在着如方法选择不当或者错误,过度治疗,医患信任危机,医疗伦理道德的丧失等情况,我们应该用矛盾分析的方法来思考这些问题.     

预期想象对拖延的影响:想象过程和想象结果的效应分离

摘要 为了考察预期想象对不同拖延水平个体拖延行为的影响,本研究采用一般拖延量表(General Procrastination Scale)选取高拖延被试和低拖延被试,要求被试在进行模拟现实的拖延任务之前分别对任务过程和任务结果进行预期想象,比较不同拖延水平的被试在预期想象作用下拖延行为的变化。结果表明：(1)在两组被试中,相比于无想象条件下的拖延行为,对任务过程的预期想象增强拖延行为,对任务结果的预期想象削弱拖延行为;(2)对任务不同成分的预期想象所引发的情绪与拖延行为的变化相关显著。这说明情绪和预期想象是影响拖延的重要因素,合理地操纵对任务不同成分的预期想象可以有效干预拖延行为。     

负性情绪材料的定向遗忘及心理机制

采用项目法定向遗忘的研究范式,在两个实验中分别采用文字和图片材料考察了情绪性记忆定向遗忘的效果及其心理机制。实验中采用了中性和负性两种实验材料,设置了两种记忆指令出现时间（2秒后提示和5秒后提示）,相对于中性材料,被试更不容易忘记负性材料。记忆指令出现的时间只影响图片材料的定向遗忘。研究表明负性情绪会干扰定向遗忘,选择性编码理论可以解释情绪性文字材料的定向遗忘,而抑制理论更能解释情绪性图片材料的定向遗忘效应。
