基本心理能力老化的认知机制

基本心理能力老化机制是认知老化领域研究热点之一。横断研究与追踪研究表明, 感觉功能、加工速度、工作记忆等信息加工资源的衰退导致了基本心理能力的衰退。但由于相关研究不能进行因果推论, 基本心理能力老化的认知机制尚存在争论。因此本项目拟采用实验室研究和干预实验设计, 通过操纵感觉功能(知觉压力水平)、干预加工速度与工作记忆, 考察基本心理能力的年龄差异的变化, 以期为认知老化理论的深化和拓展提供实验依据。     

视知觉压力在基本心理能力老化中的作用

信息降格说认为, 感觉功能老化使认知系统难以获得良好的信息输入, 并必须牺牲有限的认知资源获得更好的刺激信息, 使能用于认知加工的资源不足, 造成认知老化。为探讨感觉功能对基本心理能力老化的作用, 该研究采用2(年龄组：年轻、老年组)×4(视知觉压力水平：高、中、低、无噪音)的混合设计, 考察年轻、老年组在相同视知觉压力下基本心理能力的年龄差异。结果发现和无噪音条件相比, 相同视知觉压力下基本心理能力(数字能力、归纳推理能力)的年龄差异减小, 甚至消失, 一定程度上支持信息降格说。视觉功能衰退可能是影响基本心理能力老化的重要因素, 但这种作用受认知资源的调节。     

心理资本对大学生就业能力的影响

通过对251名大学生的问卷调查,探讨了心理资本对大学生就业能力的影响.研究表明,年级、家庭所在地以及家庭所在地与是否为独生子女的交互作用对心理资本有显著影响;年级与是否为独生子女的交互作用影响大学生就业能力.另外,心理资本中的自我效能感、韧性和乐观三个维度对就业能力有积极影响.研究认为,大学生本人和高校可采取多种措施,通过培养和提升心理资本来提高大学生就业能力.     

买卖交易中谈判者角色影响谈判结果的机制

现实生活中的谈判通常发生在特定的社会情境中, 谈判者也总在扮演着某种角色。本研究探索了买卖交易谈判中谈判者角色影响谈判结果的作用机制。研究提出了一个关于谈判者角色诱发框架效应的理论模型, 然后通过两个模拟谈判实验对这一模型进行验证。实验1表明, 买家知觉到的馅饼大于卖家知觉到的馅饼, 且谈判者知觉到的馅饼在谈判者角色与谈判者绩效间起部分中介作用。实验2发现, 即使保留买家与卖家的角色标签, 如果剥离了金钱作为交易介质这一重要特征, 两个谈判角色知觉到的馅饼也没有差异。研究揭示了谈判者角色影响谈判结果的作用机制, 对谈判者如何利用情境因素取得更好的谈判结果具有实践意义。     

心理旋转训练对5~6岁儿童空间能力和数学能力的影响

采用2（时间：前测/后测）×2（分组：实验组/控制组）的两因素混合实验设计,考察心理旋转游戏训练对5~6岁儿童空间及数学能力的影响。基于心理旋转的可塑性以及空间能力与数学能力之间的密切关系设计心理旋转干预方案,将36名被试分为实验组和控制组进行为期8周共24次的干预研究。研究结果表明：（1）空间能力与数学能力之间显著正相关;（2）心理旋转游戏有效地提高了5~6岁儿童的空间能力和数学能力,该训练方案具有良好的即时效果。

为了探讨大学生抗挫折心理能力对自杀意念的影响,采用《抗挫折心理能力问卷》和《自杀意念自评量表》对882名大学生进行调查研究.结果发现:(1)大学生抗挫折心理能力在性别、年级、生源、学校类型等因素上存在显著差异;(2)大学生抗挫折心理能力与自杀意念之间呈显著的负相关,抗挫折心理能力的多个因素与自杀意念各因素之间的负相关显著;(3)大学生的挫折容忍力、意志品质、挫折复原力、信心、挫折认知水平、挫折经验是自杀意念的有效预测变量.     

心理理论和语言能力的关系

心理理论和语言能力的关系已日益引起研究者们的关注.文章综述了以非人灵长类动物、正常儿童和特殊人群为对象进行的有关心理理论和语言关系的研究,从比较和发展的角度进行了理论分析.提出一定的语言能力水平也许是通过心理理论测试的前提条件,但二者有着不同的发展规律,并表现为复杂的共存关系.     

西北民族地区中学生心理地位与人际交往能力的关系研究

以西北民族地区甘南藏族自治州的1所多民族混合学校、1所单一少数民族学校以及兰州市1所普通中学的521名中学生为被试,采用心理地位量表和中学生人际交往能力问卷,探讨不同学校类型中学生心理地位和人际交往能力的关系。结果表明:(1)西北民族地区藏汉混合学校学生的心理地位显著高于单一民族中学的学生,但与普通中学的学生之间不存在显著差异;(2)西北民族地区藏汉混合学校学生人际交往能力得分显著高于单一民族中学的学生,但与普通中学学生之间差异不显著;(3)西北民族地区中学生的心理地位与人际交往能力之间存在显著相关;(4)西北民族地区中学生的心理地位特征能够较好地预测其人际交往能力的发展水平。     

心理韧性儿童的社会能力自我觉知

旨在考察心理韧性儿童与缺乏心理韧性儿童相比社会能力自我觉知特点, 以探究社会能力自我觉知的心理韧性发展意蕴。利用量表法和内隐联结测验(IAT), 对经由汇聚操作法筛选出的99名心理韧性儿童和176名缺乏心理韧性儿童, 分别测量社会能力外显自我觉知与内隐自我觉知, 并从2个信息源多角度测量其实际社会能力。结果发现：心理韧性儿童比缺乏心理韧性儿童有更高水平的社会能力外显自我觉知, 社会能力自我觉知与心理社会发展功能总体上存在极其显著的正向关联; 心理韧性组儿童自我觉知的社会能力低于其实际社会能力但两者显著正相关, 缺乏心理韧性组儿童自我觉知的社会能力接近于其实际社会能力但两者不存在显著相关, 两组儿童自我觉知的社会能力与实际社会能力之差的差异极其显著; 心理韧性儿童在内隐社会能力自我觉知测验不相容任务与相容任务上反应时之差显著大于缺乏心理韧性儿童。这提示, 外显上谨慎一致的高水平社会能力自我觉知和内隐上更倾向于认为自己有能力或为心理韧性发展的主体性机制原因之一。

On the language specificity of basic number processing: transcoding in a language with inversion and its relation to working memory capacity

Transcoding Arabic numbers from and into verbal number words is one of the most basic number processing tasks commonly used to index the verbal representation of numbers. The inversion property, which is an important feature of some number word systems (e.g., German einundzwanzig [one and twenty]), might represent a major difficulty in transcoding and a challenge to current transcoding models. The mastery of inversion, and of transcoding in general, might be related to nonnumerical factors such as working memory resources given that different elements and their sequence need to be memorized and manipulated. In this study, transcoding skills and different working memory components in Austrian (German-speaking) 7-year-olds were assessed. We observed that inversion poses a major problem in transcoding for German-speaking children. In addition, different components of working memory skills were differentially correlated with particular transcoding error types. We discuss how current transcoding models could account for these results and how they might need to be adapted to accommodate inversion properties and their relation to different working memory components.     

Need for closure and dealing with uncertainty in decision making context: The role of the behavioral inhibition system and working memory capacity

The aim of the present study was to investigate the moderated mediation model of the relationship between the behavioral inhibition system (BIS), need for closure (NFC) and working memory capacity (WMC) in the decision making process. It was assumed that NFC works as a motivational mechanism that enables individuals high in BIS to deal with uncertainty; therefore, NFC mediates the effect of BIS on behavior in a decision-making situation. Moreover, as uncertainty management requires cognitive resources, we expected WMC to moderate this relationship. In line with our hypothesis, we found that NFC mediated the relationship between BIS and the information search about the job candidates, and this effect occurred only for individuals high in WMC. We discuss these results in the context of effective self-regulation, as well as motivational and cognitive determinants of effort.

The Use of Acceptance and Commitment Therapy to Promote Mental Health and School Engagement in University Students: A Multisite Randomized Controlled Trial

The aim of this multisite randomized controlled trial was to determine whether an intervention based on Acceptance and Commitment Therapy (ACT) was efficacious in improving university students’ psychological flexibility, mental health, and school engagement. Students were recruited in four Canadian universities and randomly assigned to an intervention (n = 72) or a wait-list control group (n = 72). Students in the intervention group took part in four 2.5-hour workshops during a 4-week period and were asked to do exercises at home (e.g., meditation, observation grids). Wait-list students received the intervention soon after the post measurements. MANCOVAs and ANCOVAs revealed that students in the intervention group showed greater psychological flexibility at postintervention than those in the control group. They also reported greater well-being and school engagement, and lower stress, anxiety, and depression symptoms. Taken together, results of this study suggest that an ACT-based intervention offers a valuable way to promote mental health and school engagement in postsecondary settings.

The relative contributions of subjective and objective measures of body shape and size to body image and disordered eating in women

This research explored the relative contributions of subjective perceptions of body weight and body shape/proportion, as well as objective measures of body mass index (BMI) and waist-to-hip ratio (WHR) to disordered eating, exercise involvement, and body image. One hundred and fifty-eight female university students completed questionnaires and provided body measurements for this study. Although an interaction between BMI and WHR was found for some measures (i.e., Eating Disorder Examination Questionnaire total and subscale scores), results indicated that BMI was consistently the better objective predictor of disordered eating and body image. Subjective perceptions of body weight and, to a lesser extent, body shape, were found to account for the greatest proportion of variance in the dependent measures (disordered eating, body esteem, and body dissatisfaction). Overall, these results offer more support for sociocultural theories emphasizing the importance of thinness for women, than evolutionary theories emphasizing the role of WHR.     

不同5-HT3受体拮抗剂预防腹腔镜术后恶心呕吐的临床观察

观察使用不同5-HT3受体拮抗剂预防全麻下腹腔镜手术术后恶心呕吐的临床效果。选择160例气管内插管全身麻醉下腹腔镜手术,随机分四组,每组40例,手术结束前30min分别静脉注射昂丹司琼4mg（A组）;托烷司琼2mg（B组）;格拉司琼3mg（C组）;D组为对照组。记录术后2h、6h、12h、24h患者恶心、呕吐出现的例数。结果四组患者术后恶心呕吐的发生率是一个逐渐下降的趋势,A、B、C三组与D组相比较有显著性差异（P〈0．05）;术后2h、6h、12hB组与A组、C组相比较有显著性差异（P〈0．05）;而术后24hA、B、C三组差异无统计学意义,A、B、C三组抑制恶心呕吐的有效率分别为67．5％、87．5％和70．0％,与对照组比较差异有统计学意义（P〈0．05）,随访患者24h内无与药物相关的不良反应。结论：三种药物都能有效地预防术后恶心呕吐,但12h内托烷司琼的有效性更为明显。     

The Links Among Perceived Adherence to the System of Care Philosophy,Consumer Satisfaction,and Improvements in Child Functioning

The present study investigated the associations among perceived adherence to the system of care philosophy, changes in internalizing and externalizing behaviors, and consumer satisfaction with services. Participants included 98 families, interviewed at two time points across a one-year period. Hierarchical multiple regressions indicated that the more a child and family perceived services to be consistent with the system of care philosophy, the greater their level of satisfaction with services and the fewer internalizing and externalizing behaviors they reported one year after receiving services (controlling for initial levels of problem behaviors). Implications for children’s mental health service delivery are offered.
