基于多层验证性因素分析的各种信度系数方法

近年来,心理学研究的复现性受到广泛关注,许多实证研究难以重复验证,信度较低。大量研究使用多层技术,但只报告整体信度,导致研究可重复危机。基于各种信度系数和验证性因素分析的理论,以二层模型为例,总结多层信度计算方法,通过文献综述检索应用情况,并用MPLUS进行实例演示,最后讨论单层信度估计存在的偏差及分层估计的好处。总之,对多层数据进行分层信度估计是很有必要的,可消除因测量工具缺乏信度而导致的研究不可重复。     

基于因果报应观念的认知调查与厚黑行为抑制效果分析

因果报应是中国传统文化的一个重要观念,至今仍然影响着当下社会大众。研究通过问卷调查来了解社会大众对因果报应的认知与理解,并进一步通过启动实验考察因果报应启动对厚黑行为的抑制效果,研究结果表明:(1)社会大众对因果报应的认知与接纳是一种客观存在,55.83%的被试知晓因果报应,33.81%的被试表示相信因果报应的存在,10.09%的被试表示因果报应很灵验,23.67%的被试表示因果报应影响自己的行为处世,22.96%的被试表示会用因果报应提示教育身边的亲友。(2)因果报应材料的启动能显著地抑制厚黑行为,中性材料的启动不能抑制厚黑行为,因果报应启动的内容与厚黑人格对厚黑行为具有交互效应,因果报应启动能更显著地抑制高厚黑人格被试的厚黑行为。基于社会治理的视角,社会公众对因果报应的接纳成就了其参与社会治理的可能性,因果报应内蕴的道德自律、匡扶正义、累德向善等价值内核成就了其参与社会治理的效用性,因果报应观念应建设性发掘和创造性地转化为当下的社会治理所用。     

睾酮与人类决策行为

睾酮是一种类固醇激素, 主要的雄性激素之一。在神经科学与神经内分泌学领域中, 早期研究发现睾酮会对人类的攻击性、社会交往、冲动性等方面产生一定的影响; 后来心理学研究者开始关注睾酮与决策之间的关系, 包括社会性决策的信任、合作、利他与竞争方面以及经济性决策的风险决策。多项研究显示, 睾酮的水平与经济性决策中的风险寻求行为呈正相关关系; 在社会性决策领域中, 高睾酮水平的个体会表现出更高的攻击性、支配性和公平性行为, 同时表现出更低的人际信任。然而这些研究结果也存在难以重复验证的现象, 需要更多的研究探寻可能影响睾酮与决策的其他因素。未来对睾酮与决策的研究可以关注睾酮与消费决策领域、探寻青少年睾酮水平与社会行为的关系以及临床应用等。     

The correlations of socioeconomic status,disease activity,quality of life,and depression/anxiety in Chinese patients with rheumatoid arthritis

This study aimed (i) to investigate the relationships among socioeconomic status, disease activity, quality of life, and the psychological status in Chinese rheumatoid arthritis (RA) patients; (ii) to explore the possible risk factors of anxiety and depression. A total of 160 RA patients underwent standardized laboratory examinations and completed several questionnaires. Independent samples t-tests, χ² analyses, and logistic regression modeling were used to analyze the data. We found 30.6% RA patients were anxiety, and 27.5% had depression, which were significantly higher than the control group (7.8 and 11.7%, respectively). And there were significant correlations among education, pain, disease activity, medication adherence, functional capacity, quality of life, and anxiety/depression. Meanwhile, logistic regression analysis revealed that poor quality of life and low education level were significantly associated with anxiety/depression in RA patients. In conclusion, there were significant relationships among education, quality of life, and anxiety/depression in Chinese RA patients.     

Evaluating the Impact of Careless Responding on Aggregated-Scores: To Filter Unmotivated Examinees or Not?

When examinees' test-taking motivation is questionable, practitioners must determine whether careless responding is of practical concern and if so, decide on the best approach to filter such responses. As there has been insufficient research on these topics, the objectives of this study were to: a) evaluate the degree of underestimation in the true mean when careless responses are present, and b) compare the effectiveness of two filtering procedures in purifying biased aggregated-scores. Results demonstrated that: a) the true mean was underestimated by around 0.20 SDs if the total amount of careless responses exceeded 6.25%, 12.5%, and 12.5% for easy, moderately difficult, and difficult tests, respectively, and b) listwise deleting data from unmotivated examinees artificially inflated the true mean by as much as .42 SDs when ability was related to careless responding. Findings from this study have implications for when and how practitioners should handle careless responses for group-based low-stakes assessments.     

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。     

走神对中文阅读绩效的影响

选取36名大学生被试,采用探针检测的方法和逐句阅读范式,考察被试阅读中文材料时走神对阅读正确率和阅读时间的影响。结果发现:(1)中文阅读中出现走神的时间占34.80%;(2)走神会影响阅读理解,降低阅读理解正确率;(3)走神会导致阅读时间变慢。这些发现均证实走神对中文阅读绩效有影响,降低阅读理解正确率和减缓阅读时间。     

Seeing the big picture: Broadening attention relieves sadness and depressed mood

We examined whether the broadened attentional scope would affect people's sad or depressed mood with two experiments, enlightened by the meaning of “seeing the big picture” and the broaden‐and‐build model. Experiment 1 (n = 164) is a laboratory‐based experiment, in which we manipulated the attentional scope by showing participants zoomed‐out or zoomed‐in scenes. In Experiment 2 (n = 44), we studied how depressed mood and positive and negative emotions were affected when participants watched distant versus proximal scenes for eight weeks in real life. Healthy participants in Experiment 1, who were induced to feel sad, could return to the baseline mood after having the broadened attention task but not after having the narrowed attention task, which indicated that immediate attention broadening manipulation could function as antidotes for the lingering effects of induced negative emotions. Participants with depressed mood in Experiment 2 showed reduced depressed mood, increased positive affect, and decreased negative affect after receiving attention broadening training compared to those receiving attention narrowing training. Our findings suggest a robust role of broadened attentional scope in relieving negative emotions and even mildly depressed mood in the long run.     

运动技能水平与躯体感觉输入对运动表象的影响

运动表象质量与运动技能水平有关,运动表象质量随着运动技能水平的提高而上升。器械使用可使人脑产生可塑性改变,使用者会将器械纳入身体图式。然而,两者影响运动表象的神经心理机制还不清楚。本研究采用功能性磁共振成像探析篮球运动员与新手在不同持球条件下表象投篮时脑功能活动的差异。结果表明运动员表象质量较好,镜像神经系统激活高于新手;持球条件下运动员表象质量显著高于不持球条件下,镜像神经系统激活程度显著低于不持球条件下。研究说明持器械可以显著提高运动员的表象质量,器械使用带来镜像神经系统的可塑性变化。     

Does Parent-Child Interaction Therapy Reduce Maternal Stress,Anxiety, and Depression Among Mothers of Children with Autism Spectrum Disorder?

Maternal stress, anxiety, and depression are associated with ineffective parenting strategies for families of children with Autism Spectrum Disorders (ASD). We present the use of Parent-Child Interaction Therapy (PCIT) with three mother-child dyads to reduce maternal stress, anxiety, and depression and child disruptive behavior in children with ASD. Results included increases in positive parenting skills, and decreases in maternal anxiety, depression, and stress, as well as child behavior problems. PCIT is a promising alternative to more intensive and costly interventions, both at reducing disruptive behaviors and improving maternal health. Implications of PCIT for dyads affected by ASD are discussed.
