Infant sustained attention but not joint attention to objects at 9 months predicts vocabulary at 12 and 15 months

Vocabulary differences early in development are highly predictive of later language learning as well as achievement in school. Early word learning emerges in the context of tightly coupled social interactions between the early learner and a mature partner. In the present study, we develop and apply a novel paradigm—dual head‐mounted eye tracking—to record momentary gaze data from both parents and infants during free‐flowing toy‐play contexts. With fine‐grained sequential patterns extracted from continuous gaze streams, we objectively measure both joint attention and sustained attention as parents and 9‐month‐old infants played with objects and as parents named objects during play. We show that both joint attention and infant sustained attention predicted vocabulary sizes at 12 and 15 months, but infant sustained attention in the context of joint attention, not joint attention itself, is the stronger unique predictor of later vocabulary size. Joint attention may predict word learning because joint attention supports infant attention to the named object.     

Sharing economy promotes morality,not impedes it

Sharing economy (SE) is a rapidly growing economic model which has brought people efficiency and convenience; however, it also provides users the opportunity to misbehave, which has raised public concerns about the moral crisis that it might cause. We examined the effect of SE on individuals’ unethical behaviors through four studies. We found consistently that making people believe that they were using shared goods (Study 1) or priming them with abstract SE mindsets (Studies 2–4) reduced, not facilitated, their subsequent cheating on task performances to gain monetary rewards. Moreover, the effect of SE on cheating was mediated by a sense of connecting to others (Study 4). Thinking of using SE enhanced individuals’ interpersonal closeness, which in turn led to less unethical behavior. However, correlational analyses in Studies 3 and 4 showed that people who cheated more in studies in the laboratory also reported using SE more frequently in real life. Implications of these findings are discussed.     

禅修对创造性思维的影响

禅修是一种能够对人类心理有广泛影响的训练工具。作为两种重要、相似但又不同的禅修方式, 冥想和正念对创造性思维中的发散思维和聚合思维产生了不同影响。在发散思维方面, 冥想主要通过对注意调控和无意识激活影响以及对解题动机和情绪的有效调控两方面显著增强了发散思维, 尤其是认知灵活性; 在聚合思维方面, 正念和冥想的影响相当复杂, 主要是通过聚合思维所需的执行功能和可能涉及表征重构来促进定势转移或功能固着的消除。就机制而言, 禅修对创造性思维的影响总体上不仅得益于走神时的无意识关联加工, 而且受禅修中诱发的情绪效应的调节。基于这些, 对未来研究的趋势进行了展望。     

青少年学习倦怠量表的多元概化分析

运用多元概化理论考察青少年学习倦怠量表（ASBI）的测量学属性。结果发现,ASBI各因子以及全量表的概化系数和可靠性指数均达到较好水平,既可用于常模参照测验,也可用于标准参照测验;各因子的分量比例还不尽完善,低成就感对全域总分的贡献略低于在全量表中的分值比重,对相对误差方差贡献最大的是低成就感,学业疏离对绝对误差方差的贡献最大;今后ASBI的修订工作,可考虑对学业疏离和低成就感因子条目质量的改进,同时适当增加身心耗竭因子的条目数以提高其测量信度。     

时间焦点对前后方向上内隐时空映射的影响——来自汉族和羌族的证据

采用不同的研究方法考察汉族和羌族被试内隐时空映射的联结方向及其影响因素。实验1利用时间图表任务发现, 汉族被试对“过去在前”和“未来在前”两种内隐时空映射没有表现出明显偏好, 而羌族被试更加倾向于使用“过去在前”的内隐时空映射。由于二者均使用汉语, 但其内隐时空映射却存在差异, 显示出时间语言和时间思维的分离性。实验2利用时间焦点量表考察汉族和羌族被试对过去和未来时间的关注程度。结果发现, 前者对过去和未来的注意力程度相当, 而后者表现出较强的“过去朝向思维”, 说明文化中的时间焦点偏好可以较好地预测二者的内隐时空映射。实验3利用时间概念分类任务发现, 内隐时空映射有利于促进汉族和羌族被试时间概念的表征和加工, 出现了“隐喻一致性效应”。整个研究表明, 汉族和羌族文化中个体对待时间的态度可以决定其内隐时空映射联结方向, 支持“时间焦点假设”。     

A clean self reduces bribery intent

The present research aimed at investigating the effect of physical cleanliness on bribery intent and the moderating role of personal need for structure (PNS) on this relationship. In Study 1, we used questionnaires to establish the correlation between bodily cleanliness and bribery intent. In Study 2, we examined the effect by priming sense of self‐cleanliness. Study 3 was conducted outside a public bath to test our finding that physical purity decreases bribery intent again; we further found that individuals with high PNS showed no reduction in bribery intent even after cleaning themselves. We thus connected physical cleanliness with the corruption field and improved our understanding of its underlying moderating mechanism.     

Do Both Intrinsic and Identified Motivations Have Long-Term Effects?

This research examined the possible long-term effects of autonomous motivation on educational outcomes in the large scale High School Longitudinal Study 2009 (HSLS:09) data. We used a three-wave cross-lagged model to examine the longitudinal effects of intrinsic and identified motivation on 18,132 students in the mathematics domain and 16,684 students in the science domain. The results showed that intrinsic motivation was a long-term and effective enhancement agent on the subsequent academic performance, self-efficacy, identity, and course effort. In contrast, identified motivation might be sensitive to the contexts and was thus vulnerable to change in the long-term effects. Though identified motivation has positive effects on some immediate educational outcomes and is often regarded as “helpful” motivation, its positive effect is probably short-lived and might not last long in real life educational settings.     

单字词识别中多义词识别优势效应的年龄特点

采用词汇判断任务,以小学三年级、五年级儿童以及大学生为被试,考察单字词识别中的多义词识别优势效应的年龄特点.结果发现:(1)三组被试都表现出单字词识别中的多义词识别优势效应,且效应发生在低频字上;(2)随年龄的增长和识字能力的提高,儿童汉字识别的错误率降低;而多义词识别优势效应呈现递减的趋势.小学三年级已经发展出多义词的识别优势,小学五年级的反应模式与大学生的基本接近.最后,从语义反馈量、加工方式差异等角度对结果进行了解释.     

哲学对劳动价值理论研究的关注--兼与张华夏教授的价值主客观二重性的讨论

本文在张华夏教授关于一般价值概念的基础上,提出了价值概念不仅要重视价值客体属性的状态特征,也要关注它的过程特征,从而发展了一般价值概念的结构。经济学中,四种经济价值理论分布在一般价值概念结构的不同位置上,劳动价值理论处于核心位置。是硬核。传统经济理论的危机和人力资本理论的兴起,说明理论界对劳动价值理论这个硬核的研究还是很不够的,同时从我国理论界当前的研究成果来看,马克思的劳动价值理论还有进一步发展的巨大潜力。     

怒族、傈僳族和景颇族儿童认知发展研究

采用《中小学生思维发展水平测验量表》,对怒族、傈僳族和景颇族三种少数民族390名儿童进行调查研究。结果发现：1．儿童认知发展的阶段性基本支持皮亚杰认知发展的阶段性理论,形式思维水平在13～16岁尚未形成稳定的认知结构;2．在发展的年龄上,儿童认知发展水平出现明显的“滞后”现象;3．儿童在初中一年级出现认知发展的加速期;4．三种少数民族儿童认知发展整体上不存在显著性的跨文化差异;5．认知发展在性别差异上主要体现在动作协调一空间定位能力上。
