皮质下电刺激的抑制作用

在猴和黑猩猩的大脑皮质上有某些区域,用电刺激时可以抑制运动和降低脑电图(EEG)的幅度。这些区域被称为抑制区。但是刺激这些区域所产生的抑制效果不是经常有的,在一定程度上取决于麻醉的深度。有时在刺激过后几分钟才出现。持续时间可长达30分钟。 本文报告的是在清醒的、自由活动着的动物中,通过埋植的电极,刺激脑的深部结构所观察到的抑制脑的自发电活动的现象。     

灵长动物初级抽象概括能力的比较实验研究(Ⅰ)金丝猴对实物、照片和画片的概括

本实验的目的是研究金丝猴对于从三维客体到其二维的照片及图片的概括能力。实验在三只未成年金丝猴身上进行。在基础训练中,训练动物辨别墨水瓶模型和小房子模型。然后用它们的照片和图画进行测验。实验表明三只金丝猴都不能把对客体的辨别迁移到照片和图画上去。     

Are effect sizes in self-efficacy field changing over time? A meta–meta analysis

Theories relating to self-efficacy have developed rapidly since Bandura first proposed the concept in 1977. In the past two decades, psychologists have carried out numerous studies to research the cultural and psychological changes in social development. The research topic of this study is whether self-efficacy changes over time. This study uses a meta–meta analysis and includes 13 meta-analyses, including 536 effect sizes, with a total sample size of 421,880. We find that individual self-efficacy increases over time, which may be related to social development trends. However, the effects of interventions on self-efficacy remain similar (Q_model = 1.807, df = 1, p > .05), and a possible explanation is that time effects of self-efficacy confuse the effects of intervention, because both in the intervention group and control group, the average of self-efficacy increases over time. And we find that a general decline in the predictive effects of self-efficacy (Q_model = 5.117, df = 1, p = .024), especially the ability to predict relatively objective variables (e.g. job performance, teaching effectiveness, and transfer of training). A possible explanation is that as social development people tend to overestimate their self-efficacy. Another possible explanation is that the effect sizes in the original studies being overrated, may due to intentional selective reporting or unintentional statistical errors.     

Action Generalization Across Group Members: Action Efficiency Matters

Actions are usually generalized among social group members. Importantly, the efficiency of an action with respect to achieving an external target determines action understanding, and it may have different degrees of social relevance to social groups. Thus, this study explored the role of action efficiency in action generalization. We used computer animations to simulate actions in social groups initiated by visual action cues or category labels, and we measured differences in response times between identifying actions that were and were not consistent with group members, without explicit requirements regarding generalization. It was found that in both visually introduced and explicitly labeled social groups, when the group members acted inefficiently toward the external object, perceivers identified group-consistent actions faster than group-inconsistent actions, indicating that the exemplars' common inefficient actions are generalized to the unknown ingroup member, accordingly facilitating the identification of expected consistent inefficient action (Experiment 1). As this effect was not present when removing social group cues, it was determined to be specific to social groups (Experiment 2). Importantly, such generalization was not observed when the identical action was deemed efficient toward the external object (Experiment 3) and was specific to the demonstration of the action being completed by multiple group members rather than being repeated twice by one group member, supporting the group-based inference and ruling out the possibility of the increased memorability of inefficient actions leading to more generalization relative to efficient actions (Experiment 4). Therefore, the efficiency of an action bounds the generalization of the action across social group members through a process that is spontaneous and implicit. This constrained action generalization may be due to inefficient actions being represented as culture-specific conventional forms.

Effect of Acute Psychological Stress on Motion-in-Depth Perception: An Event-Related Potential Study

The present study explored the intrinsic event-related potential (ERP) features of the effects of acute psychological stress on the processing of motion-in-depth perception using a dual-task paradigm. After a mental arithmetic task was used to induce acute psychological stress, a collision task was used to evaluate motion-in-depth perception. The error value and average amplitude of late slow waves (SW) were significantly larger for the earlier colliding spheres’ than for the later colliding spheres. The P1 peak latency in the left occipital region was significantly shorter than that of the right occipital region in the motion-in-depth perception task. Compared to the control condition, the estimated value of residual time-to-collision and error value were significantly reduced, and the N1 peak amplitude and the SW averaged amplitude were significantly increased in the stress condition. Longer motion-in-depth time improved discrimination accuracy and decreased the investment of cognitive resources. Acute psychological stress increased behavioral performance and enhanced attention resources on the motion-in-depth perception task together with greater investment of cognitive resources.     

卢梭论文明与道德——重温《论科学与艺术》

《论科学与艺术》包含了卢梭许多后来思想著述的萌芽,它讨论的是科学艺术的"近代复兴"与道德的"社会风俗"的关系。卢梭仅将科学艺术视作文明,并把它们与道德对立起来,认为近代文明失去了本原的道德精神实质。但所有的成熟文明都包含有物质文明、政治文明和精神文明三个方面,道德也是文明的产物,同时也是文明的价值和规范的基础。卢梭没有意识到,否定文明也就等于否定了道德。但卢梭文中对科学艺术的批判反思,对道德乃至宗教救赎精神的推崇,赋予其思想一种特殊的吸引力与启示意义。时代发展到今天,科学的进展和艺术的普及已经发展到了卢梭难以想象的程度,科技的兴盛固然带来了普遍的福利,却也走近了这样一个门槛:高新技术给人类带来无数方便与好处,人类的控物能力不断大幅提高;与此相比较,人类的道德自控能力若没有相应的提高,科技的发展可能带来难以预测但却可能改变人类文明命运的后果。这种不平衡无疑会是人类文明一个持久的基本矛盾。     

Assertive Ads for Want or Should? It Depends on Consumers’ Power

Advertisements using assertive language are commonly seen in marketing communications, yet assertive language has often been shown to be ineffective in communication and even decrease compliance. Recent research began to examine factors that influence the effectiveness of assertive advertising messages, but little research has studied the potential moderating role of consumer‐related factors. The current research fills this gap by investigating the moderating role of consumers’ power. Across five studies, the authors find that for high‐power consumers, assertive ads are effective in promoting want products but ineffective in promoting should products. For low‐power consumers, however, assertive ads are effective in promoting should products but ineffective in promoting want products. Moreover, the authors show that this pattern of results is driven (mediated) by consumers’ perception of the fit between the advertising message and the advertised product. Theoretical and practical implications of the findings are discussed.
