青少年同伴依恋：基于发展的视角

同伴依恋是青少年时期的一项重要的发展任务, 目前测量青少年同伴依恋的工具主要包含IPPA、PIML以及近年来才出现的AFAS量表等。在同伴依恋的影响因素中, 青少年与父母之间的依恋关系以及青少年自身的性别都可以在一定程度上预测其同伴依恋的发展状况, 性向和同伴的性别也会影响青少年对同伴依恋对象的选择, 而年龄与同伴依恋之间的关系尚不明确。此外, 安全的依恋风格预示着青少年较高的同伴关系质量, 而良好的同伴依恋关系还可以促进青少年的社会性发展。未来的研究应该着力于研究方法的改进、研究切入点的变化以及研究方向的多样化。     

注意偏向训练对社交焦虑的干预：方法、效果与机制

社交焦虑障碍是最普遍且难于治疗的精神障碍之一。大量研究发现, 注意偏向训练可以有效缓解社交焦虑。研究者从自我报告、结构化评估、生理记录等方面考察发现, 接受了注意偏向训练的社交焦虑个体其注意偏向、生理唤醒和脑神经活动发生变化并且社交焦虑症状有所缓解。注意偏向训练对社交焦虑的干预机制可能是因为训练提升了个体对威胁性刺激的注意解除能力。今后的研究可以进一步明确注意偏向训练干预社交焦虑的效果与机制, 拓宽评估注意偏向训练效果的手段, 并探索其对社交焦虑干预的长期效果和对其它心理疾病的作用。     

大学生客观社会经济地位与自尊:主观社会地位的中介作用

本研究探讨了大学生主观社会地位在客观社会经济地位与自尊间所起的作用。采用客观社会经济地位问卷、Rosenberg总体自尊量表、大学生主观社会地位问卷, 对1066名大学本科生进行调查。结果发现:大学生主观社会地位和客观社会经济地位均与自尊呈显著正相关;大学生主观社会地位在客观社会经济地位和自尊之间起显著中介作用(中介效应值为0.34)。     

早期视听整合加工——来自MMN的证据

视听整合是指当呈现的视觉和听觉信号在时间、空间上大致接近时,视觉和听觉系统倾向于整合的加工过程。失匹配负波(Mismatch Negativity,MMN)作为反映大脑早期加工的成分,表征偏差的信息输入与感觉记忆痕迹之间的神经失匹配。以MMN作为探测指标的视听整合加工研究,主要包括MMN在阅读理解中字母和语音、韵律信息、麦格克效应等方面的视听整合加工,以及分析跨通道视听整合相互竞争、相互补充的关系。未来研究需聚焦于其他通道的跨通道整合加工,同时应拓展MMN的诱发范式。     

视觉选择性注意对注意缺损多动障碍儿童数字距离效应的影响

采用Posner的内源性和外源性线索实验范式,材料为1~9的阿拉伯数字(不包括5),以判断目标数字是否大于5为任务,考察视觉选择性注意中的内源性注意和外源性注意对注意缺陷型多动障碍儿童(ADHD)数字加工距离效应的影响。结果发现:(1)内源性和外源性注意条件下,正常儿童在数字判断加工任务中的反应时短于ADHD儿童;(2)内源性有效线索提示条件下,ADHD儿童和正常儿童均表现出显著的数字距离效应;而无效线索提示条件下,ADHD儿童的大小数字距离效应均不明显,正常儿童仍然表现出显著的数字距离效应;(3)外源性有效线索提示条件下,ADHD儿童的小数字距离效应显著,但大数字距离效应不明显,正常儿童则表现出显著的大小数字距离效应;而无效线索提示条件下,只有正常儿童表现出显著的数字距离效应,ADHD儿童的数字距离效应不显著。     

价值驱动注意捕获:独立机制还是伴随作用?

近年来,在注意捕获研究领域,价值驱动注意捕获越来越受到学者的关注。对于价值影响注意捕获作用机制,一些学者认为是一种伴随机制,而另一些学者认为是一种独立机制。文章在对近年相关文献回顾的基础上,对这两种观点的研究范式、相同点及争议进行了总结。未来研究方向可以聚焦在价值驱动注意捕获的实验方法、作用特点等方面以及特殊群体、跨文化比较等领域。     

群际接触对外群体信任的影响:内群体认同的中介效应

目的:探讨内群体认同在群际接触对外群体信任的中介效应。方法:采用内群体认同量表、群际接触量表和外群体信任量表,对570名大学生进行测量,运用SPSS13.0、Amos22.0对数据进行统计分析。结果:内群体认同作为中介变量,群体接触通过内群体认同对外群体信任的具有稳定的间接作用。     

Agreement between informant and self-reported personality in depressed older adults: what are the roles of medical illness and cognitive function?

In a sample of 77 dyads, involving depressed patients at least 50 years of age and their family or friends (informants), patient illness burden and cognitive decline were associated with self-informant rating discrepancies for facets of Revised NEO Personality Inventory (NEO-PI-R) Openness and Extraversion. Informant judgments about Neuroticism and Conscientiousness were not associated with illness burden or cognitive function, underscoring the potential utility of risk-detection strategies that rely on informant-report in these two domains. Findings suggest the need for research on how patient illness severity and cognitive function affect how friends and family use or misuse information when making judgments about older depressed patients.     

Outlying Observation Diagnostics in Growth Curve Modeling

Growth curve models are widely used for investigating growth and change phenomena. Many studies in social and behavioral sciences have demonstrated that data without any outlying observation are rather an exception, especially for data collected longitudinally. Ignoring the existence of outlying observations may lead to inaccurate or even incorrect statistical inferences. Therefore, it is crucial to identify outlying observations in growth curve modeling. This study comparatively evaluates six methods in outlying observation diagnostics through a Monte Carlo simulation study on a linear growth curve model, by varying factors of sample size, number of measurement occasions, as well as proportion, geometry, and type of outlying observations. It is suggested that the greatest chance of success in detecting outlying observations comes from use of multiple methods, comparing their results and making a decision based on research purposes. A real data analysis example is also provided to illustrate the application of the six outlying observation diagnostic methods.     

Prevalence and Correlates of Direct Self-Injurious Behavior among Chinese Adolescents: Findings from a Multicenter and Multistage Survey

Direct self-injurious behavior (DSIB) has become an important focus due to its perniciousness and perplexity. Little is known about its prevalence and correlative factors in Chinese adolescents, including how data may differ according to gender. A multicenter, multistage stratified cluster random sampling was used to examine the previous 12-month prevalence of DSIB, as well as the possible correlates of demographics, risky behaviors, suicidality, and psychosocial factors associated with DSIB in a school-based sample of 11,880 students (49.5 % boys and 50.5 % girls). Approximately 30 % of the adolescents in the sample reported at least one incident of DSIB in the past 12-month period. After controlling for demographic variables, analyses of the independent relationships of DSIB with risky behaviors, suicidality, and psychosocial factors were conducted for each gender. Smoking, binge drinking, running away from home, suicide ideation, suicide plans, positive affect, and physical symptoms were identified as common factors associated with DSIB for both genders in the final model. In addition, truancy, fighting, physical inactivity, motor impulsiveness, and depressed affect were found to be related to DSIB in boys, whereas suicide attempts and somatic complaints were found to be related to DSIB in girls. Separation anxiety and social anxiety associated negatively with DSIB in boys and girls, respectively. DSIB was not found to independently relate to attention impulsiveness, non-planned impulsiveness, self-esteem, or harm avoidance in either genders. DSIB was prevalent in Chinese adolescents. Programs intended to promote physical and mental health in adolescents should take into account gender differences in DSIB-associated factors, including risky behaviors, suicidality, and psychosocial factors.
