多特征刺激在视觉工作记忆中的存储模式

使用事件相关电位技术, 采用变化觉察范式, 以双色块和单色块为刺激材料, 通过两个实验探讨了多特征刺激在视觉工作记忆中的存储模式。实验1通过对双色块和单色块的比较来考察特征数量对视觉工作记忆资源分配的影响, 通过操控双色方块的变化幅度来考察精度需求对资源分配的影响。结果发现, 特征数量的增加诱发了更强的对侧延迟活动(CDA), 而精度需求的提高并没有引起对侧延迟活动上的差异, 却诱发了指示自上而下的控制的晚期正成分(LPC)的增强。实验2通过在测验阶段加入指示可能变化的部分的提示符, 发现提示符并未能促进变化觉察的行为反应。整个研究表明, 特征数量影响视觉工作记忆资源的分配, 而精度需求并不起作用, 同时多特征刺激在视觉工作记忆中的存储单位并不是单个的独立特征, 而是整合的客体。     

儿童同伴群体活动中的性别排斥

实验一以图片为材料研究了儿童同伴群体活动中的性别刻板印象。实验二以情景故事法研究了儿童在不同排斥情景中发生性别排斥的原因即其与性别刻板印象的关系。被试为幼儿园大班、2年级和5年级儿童。结果发现,（1）在同伴群体活动中三个年龄段的儿童都存在着明显的性别刻板印象。（2）同伴群体活动中的性别排斥行为并不是由性别刻板印象引起的。（3）儿童会以道德和亲社会行为为理由接纳异性儿童,会因为群体认同、群体功效和刻板印象而排斥异性儿童。     

齐国部分疑异人物考辨

自齐国作为封国建立后,其历史人物,有籍可考的不少于463人。大部分的人物清晰可辨,但仍有些人物存在疑异。有些是人物本身事迹不明了,有些则是人物之间存在疑异。本文试就宾胥无与弦章、东郭牙与鲍叔牙和东郭邮、章子与匡章这三组有争议的历史人物进行考辨,以期还其本来历史面目。     

儒家文化在心理健康教育中的价值

“健康是人类的肉体、精神和社会康乐的完美状态,而不是仅仅指无疾病或无体弱的状态。”随着医疗卫生事业的发展,身体疾病对人类健康的威胁已相对减少,而因生活中的各种矛盾使人遭受挫折所引起的心理疾病却日益增多。作为人类智慧结晶的儒家文化,对于提高现代人的心理素质和增进心理健康会起到潜移默化的积极作用。     

Set points of positivity ratio for different levels of well‐being: A latent profile analysis

Previous studies have explored the set points of the positivity ratio by grouping according to predetermined cut‐off scores, resulting in inconsistent criteria and unstable results. This study intends to further explore the set points of the positivity ratio using latent profile analysis. Two samples of 716 college students and 381 adults in China completed the Questionnaire for Eudaimonic Well‐Being, the Personal Growth Subscale from Ryff's Psychological Well‐being Scale, the Need Satisfaction Questionnaire, and the Emotional Experience of Well‐Being Questionnaire. College students were classified into four classes (2.0, 2.8, 3.7 and 5.0) with the set points of the positivity ratio, whereas adults were classified into three classes (1.9, 2.9 and 4.2) with the set points of the positivity ratio. The difference of the set points between college students and adults was nonsignificant for medium and high well‐being classes, and significant with a small effect size for the higher well‐being class. Future research should examine more diverse samples and combine the real experience method to further explore the set points of the positivity ratio.     

A simplified version of the maximum information per time unit method in computerized adaptive testing

In this article, we propose a simplified version of the maximum information per time unit method (MIT; Fan, Wang, Chang, & Douglas, Journal of Educational and Behavioral Statistics 37: 655–670, 2012), or MIT-S, for computerized adaptive testing. Unlike the original MIT method, the proposed MIT-S method does not require fitting a response time model to the individual-level response time data. It is also computationally efficient. The performance of the MIT-S method was compared against that of the maximum information (MI) method in terms of measurement precision, testing time saving, and item pool usage under various item response theory (IRT) models. The results indicated that when the underlying IRT model is the two- or three-parameter logistic model, the MIT-S method maintains measurement precision and saves testing time. It performs similarly to the MI method in exposure control; both result in highly skewed item exposure distributions, due to heavy reliance on the highly discriminating items. If the underlying model is the one-parameter logistic (1PL) model, the MIT-S method maintains the measurement precision and saves a considerable amount of testing time. However, its heavy reliance on time-saving items leads to a highly skewed item exposure distribution. This weakness can be ameliorated by using randomesque exposure control, which successfully balances the item pool usage. Overall, the MIT-S method with randomesque exposure control is recommended for achieving better testing efficiency while maintaining measurement precision and balanced item pool usage when the underlying IRT model is 1PL.     

主动性人格:机制与未来走向

主动性人格(proactive personality)作为一种独特的人格特质,指采取积极行动去影响所处环境的一种个体倾向。主动性高的个体善于发现机会,抓住机会,并且不断地坚持目标。研究者梳理了主动性人格的起源和概念、测量方法,阐述了主动性人格的实施效果、中介机制和调节机制,强化了中国本土文化的权变作用。未来研究应继续完善主动性人格的概念、开发符合时代特征的测量工具、拓展其研究层次与实施效果。     

多阶段混合增长模型的方法及研究现状

多阶段混合增长模型(PGMM)可对发展过程中的阶段性及群体异质性特征进行分析,在能力发展、行为发展及干预、临床心理等研究领域应用广泛。PGMM可在结构方程模型和随机系数模型框架下定义,通常使用基于EM算法的极大似然估计和基于马尔科夫链蒙特卡洛模拟的贝叶斯推断两种方法进行参数估计。样本量、测量时间点数、潜在类别距离等因素对模型及参数估计有显著影响。未来应加强PGMM与其它增长模型的比较研究;在相同或不同的模型框架下研究数据特征、类别属性等对参数估计方法的影响。     

贫困问题:基于心理学的视角

贫困心理学,是在心理学视角下研究贫困问题的一种新研究取向,是心理学在贫困领域的最新运用。现阶段贫困心理学研究主要集中在主观幸福感、心理健康、行为决策等三个方面。贫困文化理论、稀缺理论、自我损耗论分别从贫困文化、稀缺心态以及意志力资源视角解释了贫困产生的心理机制。在摆脱贫困过程中需要打破贫困循环,未来贫困心理学研究需要进一步探讨贫困的产生机制、神经生理机制,贫困心理学的本土化研究以及心理学在扶贫工作中的应用等。     

A Developmental Study of Chinese Children’s Word and Character Reading

To investigate the relationship between Chinese children’s character and word reading, 62 third and 50 fifth grade children in Hong Kong were asked to read single characters and words that were comprised of these characters. Results showed that words helped children to recognize characters for both grades of children. Compared to older children, younger children’s character reading was more likely to rely on the word that the character appeared in as a component; younger children made more errors in confusing the correct character with words related to it. Younger children’s greater rate of meaning-related errors also underscored the role of the word in their character learning. This study confirmed the important role of words in children’s character learning, and provided evidence for a developmental pattern of character and word reading in Chinese.
