四卡问题的内容促进效应的实验研究

本研究设计了２种抽象材料和４种具体材料的四卡问题,对４３６名大学生进行测试,以考察被试解决四卡问题时所采用的思维方式并检验命题内容对推理的影响。结果表明,四卡问题十分困难,具体内容的四卡问题并不能产生促进效应,大学生的推理表现出“匹配偏向”的特点。     

3~5岁幼儿自我延迟满足的发展特点及其中澳跨文化比较

采用实验室实验和情境观察相结合的方法,考察了我国3~5岁幼儿自我延迟满足发展的特点及中澳幼儿自我延迟满足的跨文化差异。研究结果表明：(1) 3~5岁幼儿自我延迟满足平均延迟时间随年龄增长而延长;3岁幼儿使用延迟策略少,4岁幼儿主要使用寻求策略,5岁幼儿主要使用寻求策略和自我分心、问题解决策略,自我言语控制策略在整个幼儿期始终不具有显著优势性。(2) 澳大利亚幼儿自我延迟满足发展水平高于我国同龄幼儿;在延迟策略选择上中澳幼儿既具有差异性,又具有一定的相似性;文化价值观通过教育影响着幼儿自我延迟满足的发展。     

The Ability of Face Viewpoint Transformation Remains Immature at Age of 12: Evidence from Recognition of Faces with Different Familiarity in Children

Children are immature in face recognition, particularly in face configural decoding. This study examines the developmental difference of face recognition in another mechanism: viewpoint transformation processing. Adults and sixth‐grade children were instructed to match a series of one‐tone black face silhouettes to their corresponding front‐view faces. This task involves sophisticated calculation in pictorial information, precise viewpoint transformation, and most probably a 3‐D face representation. The results showed that although the performances were well above chance level in the recognition of familiar faces, for children, they were at chance level in the recognition of unfamiliar faces. The results indicate that children, at least to the age of about 12 years, are still immature in the processing of face viewpoint transformation compared to adults.     

教师的存在能否促进视频学习?

随着网络教学和视频学习的普及, 近期大量研究关注视频学习过程中教师角色的作用。真人教师对学习的作用存在不同的理论解释：准社会交往理论、社会存在理论和社会代理理论支持真人教师能够促进学习; 而多媒体学习认知理论、认知负荷理论等则认为教师的存在会阻碍视频学习。汇总以往实证研究发现：第一, 教师对视频学习效果有比较弱的促进效应, 这主要体现在保持测验(d = 0.23)和迁移测验(d = 0.1)中; 第二, 教师对视频学习主观体验的影响主要体现在学习感知(d = 0.49), 学习兴趣(d = 0.5)和学习满意度(d = 2.21)上, 显示中等及大的效应; 第三, 教师的存在会降低学习者对视频学习材料的注视时间(d = -2.02)。未来研究仍需要从真人教师呈现方式、学习者特征、学习材料特征以及测量方式等方面加以探讨。     

观察者公正敏感性对不公正信息加工的影响

为考查观察者公正敏感性对不公正信息加工（注意、解释）的影响,该研究开展了两个实验研究。在实验一中,让被试观看不公正影片剪辑或中性剪辑后,要求他们完成视觉探测任务,判断探测刺激是在不公正词汇还是中性词汇的左边或右边;在实验二中,让被试对一个模糊的暗含不公正意义的影片剪辑中的主角进行公正性评价。结果表明,当被试不公正概念被激活后,观察者公正敏感性高的被试比观察者公正敏感性低的被试对不公正信息的注意加工更集中和更自动,同时他们对模糊的信息解释为更不公正。     

Prefrontal cortex dysfunction and income: a study in neuroeconomics

In four samples of adults, individual income was negatively associated with a measure of prefrontal cortex dysfunction even after implementing controls for age, sex, and education. The small association was stronger for men than for women. These results provide support for a neuroeconomic approach to the study of micro-economic variables.

Infants’ recognition of objects using canonical color

We explored infants’ ability to recognize the canonical colors of daily objects, including two color-specific objects (human face and fruit) and a non-color-specific object (flower), by using a preferential looking technique. A total of 58 infants between 5 and 8 months of age were tested with a stimulus composed of two color pictures of an object placed side by side: a correctly colored picture (e.g., red strawberry) and an inappropriately colored picture (e.g., green-blue strawberry). The results showed that, overall, the 6- to 8-month-olds showed preference for the correctly colored pictures for color-specific objects, whereas they did not show preference for the correctly colored pictures for the non-color-specific object. The 5-month-olds showed no significant preference for the correctly colored pictures for all object conditions. These findings imply that the recognition of canonical color for objects emerges at 6 months of age.     

Using State-Space Model with Regime Switching to Represent the Dynamics of Facial Electromyography (EMG) Data

Facial electromyography (EMG) is a useful physiological measure for detecting subtle affective changes in real time. A time series of EMG data contains bursts of electrical activity that increase in magnitude when the pertinent facial muscles are activated. Whereas previous methods for detecting EMG activation are often based on deterministic or externally imposed thresholds, we used regime-switching models to probabilistically classify each individual’s time series into latent “regimes” characterized by similar error variance and dynamic patterns. We also allowed the association between EMG signals and self-reported affect ratings to vary between regimes and found that the relationship between these two markers did in fact vary over time. The potential utility of using regime-switching models to detect activation patterns in EMG data and to summarize the temporal characteristics of EMG activities is discussed.     

On Luo Congyan’s Ethics

Luo Congyan put forward the idea that benevolence is the substance while righteousness is its function, which placed the intrinsic value of human beings on a more fundamental position and affirmed the unity of benevolent principle and universal norms from the perspective of the relationship between substance and function. The unity of benevolence and righteousness involves the connection between value and norms, and the latter relate to the relationship between morality and law in the broader sense. On the basis of the idea of using both benevolence and righteousness, Luo Congyan examined the relationship between morality and law. Corresponding to the emphasis on the role of both law and political power, Luo Congyan concerned himself with how to establish rational interpersonal relationships in various ways. Furthermore, Luo Congyan emphasized the significance of behavior in everyday life, while he affirmed that the universal principle should be followed. In this way, he developed the earlier Confucian thought. Translated from Studies in Ethics by Xiao Mo
