直接经验对自主学习意愿的影响：基于计划行为理论的应用

基于计划行为理论,自编直接经验、自主学习意愿等量表,以武汉地区402名中学生为被试,系统分析直接经验对自主学习意愿的影响。结果发现：直接经验的积累可增强学习主体参与自主学习活动的意愿;直接经验对自主学习意愿的积极影响可通过行为态度等核心变量发挥间接效应实现,也可通过直接路径实现;直接经验与自主学习意愿的关系不受行为态度等核心变量调节。这些结果表明,直接经验是自主学习意愿的重要影响因子,对培养和提高学生自主学习意识具有重要价值。     

Prosociality and morality through the lens of personality psychology

Prosociality and morality are critical to the functioning and flourishing of society. There is, however, great variation in the degree to which individuals help or hinder one another, or adhere to ethical standards of “rightness.” One way to understand this variation is by drawing on theories and models within personality psychology, which may illuminate the basic individual characteristics that drive a wide range of other-regarding tendencies. In this review, we provide a snapshot of three research strands addressing these themes. The first concerns how personality traits map onto prosocial preferences for fairness and cooperation, as studied using classic social decision-making tasks called economic games. The second concerns the robust associations between personality traits and indicators of inter-group prejudice (e.g., authoritarian ideology). The third concerns the emerging concept of moral exceptionality, and the personality traits that may characterise individuals at the forefront of moral progress. These examples demonstrate the core role that personality psychology is playing in the study of prosocial and moral behaviour, as well as the critical mass emerging in the Australian context around these themes.     

有意遗忘的脑机制

有意遗忘是指个体主动忘记无用和过时的信息,本质是记忆的主动抑制,包括定向遗忘和压抑遗忘。在定向遗忘中,记忆抑制既发生在编码阶段也发生在提取阶段,脑机制研究支持编码抑制理论和提取抑制理论;在压抑遗忘中,think和No-think所激活的脑区不同,No-think引起前额区域的激活增强和海马的激活减弱。未来应开展定向遗忘和压抑遗忘的脑机制差异研究,注重记忆抑制和其他心理活动抑制之间的差异研究,关注创伤个体的有意遗忘研究,拓展记忆控制神经网络的可塑性研究。     

2007～2009年心理学核心期刊载文的文献计量分析*

采用文献计量学的方法,以2007至2009年《心理学报》、《心理科学》、《心理发展与教育》、《心理与行为研究》、《应用心理学》、《中国临床心理学杂志》刊载的2907篇学术论文为研究对象,统计在合作情况、研究机构、研究领域、研究内容、研究方法、统计方法等方面的情况。试图通过对各项统计结果的定量分析,描述我国心理学研究的发展现状,并分析未来发展的趋势。     

正念注意觉知量表IRT分析研究*

正念注意觉知量表(MAAS)是测量正念注意水平最常用的量表之一,以中小学教师为被试,以项目反应理论用方法与技术对量表各项目的区分度、域值和信息函数峰值4个参数做了分析探讨。结果显示MMAS支持单维性假设,具有良好的心理测量学指标,对正念注意水平的测量具有较高的精准性。量表存在6个信息量很高的项目,其信息量之和接近量表总信息量的70%,提示这几个项目可以构成一个简式量表。对新量表做验证性因素分析,各项指标达到要求。     

延时间隔和线索类型对遗忘学习判断的影响*

主要探讨不同延时间隔和线索类型对遗忘元认知判断的影响。采用传统的学习判断任务,让被试学习40对无意义配对词,并告知随后进行测试,当呈现第一个词时,被试能够回忆与之配对的后一个词。让被试预测当延迟不同时间（5分钟、1天和1周）进行测试时,他们能够记住（学习判断）或者遗忘（遗忘判断）后一词的可能性。最后,要求被试回忆所有词对。结果发现延时间隔对学习判断和遗忘判断有相似的影响;学习判断的等级和相对准确性均高于遗忘判断,说明人们对记住和遗忘的线索很敏感;相比于学习判断,人们监测自己遗忘能力的信心不足。研究结果表明人们能够利用延时间隔和线索类型来预测未来的测验成绩,对遗忘的监测能力低于对记住的监测。     

大学生网络成瘾量表（修订版）的多元概化分析*

用多元概化理论考察大学生网络成瘾量表在大学生群体中应用的测量学性能。以随机测量模式的概化设计,针对1200名在校大学生进行问卷调查。结果显示双因子结构的相关程度在0.92以上,五因子结构的相关程度均在0.76~0.97间;整体量表的概化系数和可靠性指数均达到了0.94以上,而双因子结构各因子在0.90左右,五因子结构各因子均在0.74~0.85间。所以,整体量表及各因子在大学生群体中应用的信效度较高,可用作常模和标准参照测验;无论双因子还是五因子结构,CIAS-R各因子在分值比和项目数上,设计非常合理和完善。

认知诊断作为21世纪一种新的测量范式,在国内外越来越受到重视。该文运用MCMC算法实现了R-RUM的参数估计,并采用Monte Carlo模拟方法探讨其性能。研究结果表明:(1)R-RUM参数估计方法可行,估计精度较高;(2)Q矩阵复杂性和模型参数水平对模型参数估计精度有较大影响,随着r_(jk)*值的增大和Q矩阵复杂性的增加,项目参数和被试参数估计精度逐渐下降;(3)在特定情形下,R-RUM具有一定的稳健性。     

Separate Pathways for the Processing of Affordance of Neutral and Dangerous Object

Previous studies have shown that observation of object automatically elicits the activation of a reach-to-grasp response specifically directed to interact with the object, which is termed affordance. Recent findings provide evidences that even dangerous objects can evoke aversive affordances. However, these studies only focused on avoidance effect emerged with dangerous objects. It remains unclear whether the neutral object and dangerous object share a common mechanism for the processing of affordance information. The affordance effect is considered to be a type of conflict between the afforded response and the response required by the task. In a symbol judgment task, we simultaneously presented the neutral object and dangerous object to investigate whether the congruency sequence effects (congruency effects following incongruent trials are smaller than those following congruent trials) occurred across the two types of affordance conflict, which is typically assumed that such flexible adjustments can only be observed between the same conflict types. It was found that congruency sequence effects were only generated between the same types of affordance conflict (e.g., neutral object or dangerous object), but not between two different affordance conflict types (e.g., neutral object and dangerous object). These results indicate there may be two different pathways for the processing of affordance of the neutral and dangerous object.
