不同时距加工机制的比较:来自ERP的证据(Ⅰ)

采用事件相关电位的方法分析了不同时距加工机制的差异。实验采用时间两分任务,要求被试形成短(400ms)和长(1600ms)的时间判断标准,然后对7个刺激系列进行短、长的判断。结果表明时间知觉过程可以诱发出一种类似于CNV的慢性负波。对于400ms的短时距加工存在显著的半球效应,右半球的波幅显著高于左半球。1600ms的时距加工没有表现出明显的半球效应。不同时距的加工存在显著的差异。1600ms比400ms加工诱发出更大的CNV波幅。     

初中生友谊认知的类型特点

本研究在已有理论及开放式问卷基础上首先确定友谊认知的初步结构,采用探索性因素分析调整结构并筛选题目,最终确定友谊认知问卷的4个维度。验证性因素分析表明,自编的友谊认知问卷具有较好的结构效度,其他各项信效度指标也均达到心理测量学的要求。另外,聚类分析表明可以把初中生的友谊认知划分为重情感-重兴趣、重情感-轻兴趣和情感淡漠-轻兴趣3种类型。     

男性不育症临床工作的问题与思考

在临床工作中,不育越来越受到大家的重视,但仍然有许多问题困扰着我们的医疗工作者,多数医生能对男性不育症做出诊断,并给予治疗。但是由于生殖问题的复杂性和我们认识的局限性,不育症的治疗效果并不满意。在不育症诊断和治疗的思路、方法和方式中仍有许多值得探讨和改进之处。     

英文阅读材料的颜色对阅读成绩的影响

该文通过档案调查、实验和问卷调查的方法就大学英语六级考试中不同颜色文字对阅读成绩的影响进行了探索。在对北京大学和北京师范大学的2007年12月的5537份六级考试成绩档案的调查过程中,发现不同颜色试卷的阅读部分和总分成绩差异显著(蓝色低于黑色),但是这种差异并不大;选取26名被试进行实验的结果发现,题目难度和颜色之间存在边缘显著的交互作用,简单题目上蓝色比黑色成绩更低,但是这种差异在复杂题目上没有那么明显。进一步地,通过131份问卷调查数据得出,被试的阅读习惯为黑色,主观偏好也为黑色:这也是影响阅读成绩的主要因素。     

Coherence between emotional experience and physiology: does body awareness training have an impact?

Two fundamental issues in emotion theory and research concern: (a) the role of emotion in promoting response coherence across different emotion systems; and (b) the role of awareness of bodily sensations in the experience of emotion. The present study poses a question bridging the two domains; namely, whether training in Vipassana meditation or dance, both of which promote attention to certain kinds of bodily sensations, is associated with greater coherence between the subjective and physiological aspects of emotion. We used lag correlations to examine second-by-second coherence between subjective emotional experience and heart period within individuals across four different films. Participants were either: (a) experienced Vipassana meditators (attention to visceral sensations), (b) experienced dancers (attention to somatic sensations), and (c) controls with no meditation or dance experience. Results indicated a linear relationship in coherence, with meditators having highest levels, dancers having intermediary levels, and controls having lowest levels. We conclude that the coherence between subjective and cardiac aspects of emotion is greater in those who have specialized training that promotes greater body awareness.     

CTPI和CTA在椎底动脉系统TIA诊断中的互补性

研究CT灌注成像(CTPI)和CT血管造影(CTA)对椎底动脉系统短暂性脑缺血发作(TIA)的诊断价值.采用64排螺旋CT对30例患者进行常规CT、CT灌注成像和CT血管造影检查.30例CT平扫无责任病灶.CT灌注成像正常14例,异常16例.CTA正常4例,异常26例,CT灌注成像和CT血管造影联合应用有利于椎底动脉系统短暂性脑缺血发作的诊断和治疗方案的选择.     

金钱崇拜对个体跨期决策偏好的影响

采用经典跨期选择任务范式,以个体的金钱喜好差异为切入点,通过问卷调查和行为实验考察金钱崇拜对个体跨期决策偏好的影响。结果发现:(1)个体的金钱崇拜水平与其跨期折扣倾向显著负相关;(2)无论跨期决策任务的难易和兑现时间的长短,高金钱崇拜者更倾向于选择较大的延迟奖赏,而低金钱崇拜者更倾向于选择较小的即时奖赏;(3)高、低金钱崇拜者的跨期决策反应时没有明显的差异,但二者的反应时都明显地受到任务难度的影响,即在容易条件下的反应速度显著快些。结果表明,个体的金钱崇拜水平在跨期决策过程中发挥着重要的作用,致使高金钱崇拜者更愿意等待延迟大奖赏的到来。     

Perceived Social Support Mediates the Relations Between Parental Attachment and Posttraumatic Growth and Resilience in Adolescents Following the Yancheng Tornado

Previous studies have shown that parental attachment is associated with higher levels of posttraumatic growth (PTG) and resilience in individuals who have experienced traumatic events. The present study investigated perceived social support as one pathway in which parental attachment is related to PTG and resilience among Chinese adolescents who have experienced trauma by considering the role of perceived social support. Participants were 443 Chinese adolescents who had experienced a severe tornado a year prior to this study. The results showed that our model fitted the data well [χ²/df = 2.847, comparative fit index (CFI) = 0.970, TLI = 0.963, root mean square error of approximation (RMSEA) (90% CI) = 0.065 (0.056–0.073)] and revealed that perceived social support partially mediated the relationship between parental attachment, and PTG and resilience. The clinical implications and limitations of our research, and recommendations for future research are discussed in this paper.     

青少年公正世界信念对抑郁的影响:感恩和自尊的序列中介作用

为探讨青少年公正世界信念与抑郁的关系,以及感恩和自尊在二者关系中的作用机制,采用公正世界信念问卷(BJW)、感恩问卷(GQ-6)、自尊量表(SES)和流调中心用抑郁量表(CES-D)对1049名高中学生进行调查。结果发现:(1)青少年公正世界信念、感恩和自尊两两之间呈显著正相关,且三者均与抑郁呈显著负相关。(2)青少年公正世界信念通过感恩和自尊的中介作用对抑郁产生影响,且该中介效应包含了三条中介路径——感恩的简单中介效应,自尊的简单中介效应,以及感恩→自尊的链式中介作用。研究结果揭示了青少年公正世界信念对抑郁产生影响的内部心理机制,为引导青少年更好地利用公正世界信念提升感恩和自尊的水平以及更好地促进心理健康发展提供了有益建议。     

Adolescent narcissism and interpersonal trust: A cross‐lagged study

In recent years, narcissism has been attracting considerable interest by researchers because of its enigmatic constructs. To enhance our understanding of narcissists’ psychosocial functioning, considering the relationship between narcissism and interpersonal trust is crucial. This study aimed to investigate how narcissistic admiration and rivalry are associated with interpersonal trust. To gain a more nuanced understanding, a cross‐lagged design was conducted at two time points that were six months apart. In total, 357 adolescents (M_age = 16.33 years) completed the Narcissistic Admiration and Rivalry Questionnaire (NARQ) and the Interpersonal Trust Scale. The results showed that narcissistic admiration positively predicted interpersonal trust while narcissistic rivalry negatively predicted interpersonal trust at the second time point. However, interpersonal trust did not predict subsequent levels of narcissistic admiration and rivalry. These findings enhanced our understanding by showing that narcissistic admiration and rivalry have different effects on interpersonal trust, and that they remain relatively stable during a six‐month period.
