群体潜能对团队创新绩效的影响:转换型领导力的调节作用*

从团队创新内在动力视角出发,考察了群体潜能与团队绩效间的关系,并探索了转换型领导力对该作用过程的影响。研究发现:群体潜能与团队创新绩效有显著的正相关关系,该关系受到转换型领导力的调节,高水平的转换型领导力会增强两者的联系,低水平的转换型领导力会减弱两者的联系。     

双文化经验对整体加工方式的影响*

已有研究表明,与个体主义文化相比,集体主义文化易引发整体加工方式。但是,文化不仅可以按照东西方文化划分为个体主义和集体主义,还可以依据个体的文化经验划分为多元文化和单一文化。那么,与单一文化经验相比,多元文化经验,尤其是最常见的双文化经验是否也有利于整体加工方式呢?在两个实验中,我们将被试分为两组,让其中一组被试暴露在双文化情境下,另外一组被试暴露在单一文化情境下。然后让这两组被试要么寻找两段视频间的相似点或者差异点（实验1）,要么回忆与老年人刻板印象一致或不一致的信息（实验2）。结果发现,与暴露在单一文化情境下相比,暴露在双文化情境下的被试倾向于寻找事物间的相似点（实验1）,并且不易形成刻板印象（实验2）。这表明,双文化经验有利于整体加工方式。     

心理距离对基线比例忽略的影响

基线比例忽略是指在不确定情境中, 个体进行判断和决策时不能充分利用或者忽略基线比例的现象。本研究通过系列情境实验探索了三种不同维度的心理距离, 即时间距离、空间距离和社会距离对基线比例忽略的影响。结果发现, 三种心理距离均能够对基线比例忽略产生影响：当时间距离、空间距离和社会距离较近时, 个体更容易表现出基线比例忽略现象; 而当时间距离、空间距离和社会距离较远时, 个体的基线比例忽略倾向减弱。     

Eliciting Subjective Probabilities through Pair‐wise Comparisons

We propose and test a novel approach for eliciting subjective joint probabilities. In the proposed approach, judges compare pairs of possible outcomes and identify which of the two is more likely and by how much. These pair‐wise comparative judgments create a matrix of ratio judgments from which the target probabilities are extracted using the rows' (or columns') geometric means. In Study 1, subjects provided direct assessments of the likelihood of joint events (e.g., sunny days and stock market gains) and also made pair‐wise comparisons of the same joint events. Subjects in Study 2 learnt the distribution of hypothetical events pairs and provided direct and ratio estimates. In both studies, the ratio estimates were significantly more accurate than the direct estimates. The results suggest that it is possible to elicit probabilistic estimates without explictly asking for probabilities and that the pair‐wise approach is a candidate for complementing or replacing traditional elicitation approaches.

男性理想体型变化及其影响因素

现代男性对自身体型的关注程度日益升高,理想体型也发生变化,从单一的肌肉发达体型发展为低体脂高肌肉的双维度体型。影响男性理想体型的因素主要分为两类:生物因素和社会文化因素。生物因素方面,不同性别、年龄和性取向的群体拥有不同的男性理想体型;社会文化方面,社会文化通过家庭、同伴和媒体三个渠道向理想体型施加影响。未来的研究应该进一步通过实验确立体脂与肌肉双维度的男性理想体型,并结合纵向研究验证生物及社会文化因素的影响,完善男性理想体型的理论系统,为政府制定身体意象相关的干预措施和政策提供详实有力的理论依据。     

贫困问题:基于心理学的视角

贫困心理学,是在心理学视角下研究贫困问题的一种新研究取向,是心理学在贫困领域的最新运用。现阶段贫困心理学研究主要集中在主观幸福感、心理健康、行为决策等三个方面。贫困文化理论、稀缺理论、自我损耗论分别从贫困文化、稀缺心态以及意志力资源视角解释了贫困产生的心理机制。在摆脱贫困过程中需要打破贫困循环,未来贫困心理学研究需要进一步探讨贫困的产生机制、神经生理机制,贫困心理学的本土化研究以及心理学在扶贫工作中的应用等。     

Incorporating family therapy into asthma group intervention: a randomized waitlist-controlled trial

Asthma psychoeducational programs have been found to be effective in terms of symptom-related outcome. They are mostly illness-focused, and pay minimal attention to systemic/familial factors. This study evaluated a novel asthma psychoeducation program that adopted a parallel group design and incorporated family therapy. A randomized waitlist-controlled crossover clinical trial design was adopted. Children with stable asthma and their parents were recruited from a pediatric chest clinic. Outcome measures included, for the patients: exhaled nitric oxide (eNO), spirometry, and adjustment to asthma; and for the parents: perceived efficacy in asthma management, Hospital Anxiety and Depression Scale anxiety subscale, Body Mind Spirit Well-being Inventory emotion subscale, and Short Form 12 health-related quality of life scale. Forty-six patients participated in the study. Attrition rates were 13.0% and 26.0% for the active and control groups, respectively. Repeated-measures ANOVA revealed a significant decrease in airway inflammation, as indicated by eNO levels, and an increase in patient's adjustment to asthma and parents' perceived efficacy in asthma management. Serial trend analysis revealed that most psychosocial measures continued to progress steadily after intervention. Significant improvements in both symptom-related measures and mental health and relationship measures were observed. The findings supported the value of incorporating family therapy into asthma psychoeducation programs.     

Rejection Sensitivity and Executive Control: Joint predictors of Borderline Personality features

Two studies tested the hypothesis that rejection sensitivity (RS) and executive control (EC) jointly predict borderline personality (BP) features. We expected high RS to be related to increased vulnerability for BP features specifically in people who also had difficulties in executive control (EC). Study 1 tested this hypothesis using a sample of college students (N = 379) whereas Study 2 (N = 104) was conducted using a community sample of adults. Both studies operationalized EC by a self-report measure. For a subsample in Study 2 (N = 80), ability to delay gratification at age 4 was also used as an early behavioral precursor of EC in adulthood. In both studies, high RS was associated with increased BP features among people low in self-reported EC. Among those high in self-reported EC, the relationship between RS and BP features was attenuated. Study 2 found parallel findings using preschool delay ability as a behavioral index of EC. These findings suggest that EC may protect high RS people against BP features.     

Exercise training can improve spatial characteristics of time-critical obstacle avoidance in elderly people

Fall prevention programs have rarely been evaluated by quantitative movement analysis methods. Quantitative movement analyses could provide insight into the mechanisms underlying the effects of training. A treadmill obstacle avoidance task under time pressure has recently been used to evaluate a fall prevention exercise program for community-dwelling elderly people and it showed that participants improved their obstacle avoidance success rates. The mechanism, by which the increased success rates were achieved, however, remained to be determined. Participants were elderly who had fallen at least once in the year prior to participation. They were assigned to either the exercise or the control group. The control group did not receive any specific treatment. The exercise group was administered a five week exercise program, which consisted of exercises on a functionally oriented obstacle course, walking exercises, and practice of fall techniques. Pre- and post-intervention laboratory obstacle avoidance tests were conducted. Three possible determinants of success were investigated, namely avoidance reaction times, the distribution of avoidance strategies, and three spatial parameters (toe distance, foot clearance and heel distance). Analysis yielded significant TimexGroup interactions in heel distances. The exercise group increased heel distance, while the control group did not. Increased heel distance may result in reduced risk of heel contact with the obstacle and, consequently, larger success rates. The remaining parameters showed no effect of training. In conclusion, the training program was effective in improving time-critical obstacle avoidance skills. In every day life, these effects of training may contribute to less obstacle-related fall incidents in elderly. In addition, these findings could indicate that the execution of other time-critical events, like an actual fall, could also be improved by training.
