鸟类神经系统的长时程增强

揭示学习与记忆的神经机制已成为认知科学领域的一个重要研究方向。研究过程中需根据不同实验目的选用不同实验动物。LTP（long-term potentiation）是一种研究学习记忆突触基础的主要模型,其代表突触功能的可塑性。以往对LTP的研究主要集中于哺乳动物,但由于鸟类在生物进化上具有独特的地位及特有的学习记忆能力,因此通过某些鸟类行为模型将有利于对LTP特性及其与学习记忆相关性进行更深入的探索。     

Short‐term numerosity training promotes symbolic arithmetic in children with developmental dyscalculia: The mediating role of visual form perception

Studies have shown that numerosity‐based arithmetic training can promote arithmetic learning in typically developing children as well as children with developmental dyscalculia (DD), but the cognitive mechanism underlying this training effect remains unclear. The main aim of the current study was to examine the role of visual form perception in arithmetic improvement through an 8‐day numerosity training for DD children. Eighty DD children were selected from four Chinese primary schools. They were randomly divided into the intervention and control groups. The intervention group received training on an apple‐collecting game, whereas the control group received an English dictation task. Children's cognitive and arithmetic performances were assessed before and after training. The results showed that the intervention group showed a significant improvement in arithmetic performance, approximate number system (ANS) acuity, and visual form perception, but not in spatial processing and sentence comprehension. The control group showed no significant improvement in any cognitive ability. Mediation analysis further showed that training‐related improvement in arithmetic performance was fully mediated by the improvement in visual form perception. The results suggest that short‐term numerosity training enhances the arithmetic performance of DD children by improving their visual form perception.     

Goals or semantic constructs? Different choice setting and choice goal activation

The researcher of this paper contributes to the literature by identifying nuances among three types of choice settings that are likely to activate choice‐related goals and their implications for product evaluation. First, the research verifies that choice settings can activate choice‐related goals, for example, simplifying a choice. Second, it is proposed and shown that choice settings activate goals, not semantic constructs. Third, this research attempts to shed light on some nuances among different choice settings, which vary in the degree of cognitive effort used to compare alternatives. The results aid in understanding how three different choice settings can activate choice‐related goals. Fourth, the research proposes that goal activation has an implication for product evaluation, offering a new perspective to preference and choice reversal literature. Five experiments were conducted to test the hypotheses.     

Young Children Selectively Hide the Truth About Sensitive Topics

Starting in early childhood, children are socialized to be honest. However, they are also expected to avoid telling the truth in sensitive situations if doing so could be seen as inappropriate or impolite. Across two studies (total N = 358), the reasoning of 3- to 5-year-old children in such a scenario was investigated by manipulating whether the information in question would be helpful to the recipient. The studies used a reverse rouge paradigm, in which a confederate with a highly salient red mark on her nose asked children whether she looked okay prior to having her picture taken. In Study 1, children tended to tell the truth only if they were able to observe that the mark was temporary and the confederate did not know it was there. In Study 2, children tended to tell the truth only if they were able to observe that the mark could be concealed with makeup. These findings show that for children as young as age 3, decisions about whether to tell the truth are influenced by the likelihood that the information would be helpful to the recipient.     

分心抑制和关系整合对学前儿童类比推理的影响

为探究分心抑制和关系整合对学前儿童类比推理的影响,实验一先初步探究分心抑制和关系整合对25名3~4岁和26名5~6岁儿童完成含有知觉分心的类比情景任务的影响。其次,揭示知觉分心与关系整合在类比推理中的具体作用模式。实验二先初步探究分心抑制和关系整合对30名3~4岁和28名5~6岁儿童完成含有语义分心的类比情景任务的影响。其次,揭示语义分心与关系整合在类比推理中的具体作用模式。结果表明,抑制控制能显著预测儿童完成各种类型类比推理成绩,工作记忆能显著预测儿童完成含有语义分心的类比推理成绩而不能显著预测含有知觉分心的类比推理成绩。儿童完成类比情景中的分心抑制是在关系整合中完成的,当类比情景中的关系整合没有超过儿童的工作记忆容量时,知觉或语义分心才能造成对儿童类比推理的影响。     

字素-音素与词体-尾音对中国人英语语音加工的影响

研究采用命名任务,探讨了字素-音素对应规则与词体-尾音对应规则在英语假词和中高频真词读音中的作用.结果发现,中国被试同时采用字素-音素对应规则与词体-尾音对应规则命名假词和中高频真词,但是字素-音素对应规则对假词命名更重要.

荀子哲学中"善"之起源一解

一本文中的“善”泛指道德伦理领域中的正面的价值。它与“恶”相对而言,指在社会中人与人之间显示公平、友爱、正义等表现在概念上的概括。也可以说,善是跟在个人层次上损人利己,在社会层次上的弱肉强食等现象相反的价值取向。大部分人都不否认善和恶的存在。但是在二者的起源上,则存在着不同的看法。有关善和恶的起源的理论往往与哲学家们对于人性的看法有联系。一般说来,主张人性善的人需要解释恶的起源。主张人性恶的人则要解释善的起源。在中国,孟子以其性善论而闻名。他认为,人之变恶,是由于失去了本心。在西方,卢梭也主张人性善。他…     

正一道天师传承制度初探

稳定有效的宗教领袖产生制度对宗教组织的生存发展至关重要,本文通过对历代正一道天师传承关系的分析之后认为,该宗教传承制度具有四个显著特征:鲜明的差序格局;神圣与世俗的双重合法性基础;纳入国家职官管理范围;实行信物制度。天师传承制度保持了连续性和稳定性,是因为建立了良好的保障机制,即外在政权认可与扶植、民众心理与社会舆论支援以及内在宗教组织与制度支撑。
