Dogmatism and information gathering in personality impression formation

Subjects were assigned the task of forming an impression of another person with information being gathered from two conflicting sources. One half were given a positive first impression, and one half were given a negative first impression before allowing them to select additional information. Final ratings were made when Ss indicated that they had taken sufficient information. Dogmatic Ss took in less information before passing “final judgment,” gave more extreme stability ratings, expressed greater liking for their agreed-with source, and showed a trend toward a preference for explaining away impression-discrepant information rather than to withhold judgment.     

Positive contrast obtained in reacquisition following interpolation of nonreinforced or partially reinforced trials

Two experiments investigated the effects of shifting from either nonreinforcement or partial reinforcement (PRF) to continuous reinforcement conditions (CRF). In the first experiment, three groups of rats were given food reinforcement under CRF conditions in a runway followed by regular extinction trials (RE), extinction trials where Ss were delayed for 30 sec before entering the empty goal box (DE), or CRF trials where Ss were delayed for 30 sec before entering the baited goal box (DF). Then all Ss were run on the delayed reinforcement condition (DF). In the final delayed reinforcement condition, group DE ran significantly faster than group DF, reflecting positive contrast. In the second experiment, four groups of rats were trained in a runway to receive either 4% or 18% sucrose reinforcers under either PRF or CRF conditions. Then all Ss were transferred to a Skinner box and bar presses were continuously reinforced, with each S continuing to receive the same sucrose concentration as before. The former PRF Ss, regardless of the reinforcer, bar pressed at a significantly higher rate in the Skinner box than the former CRF Ss. The evidence seemed to favor the view that the effectiveness of a reinforcer is not an absolute, unchanging quantity but rather depends on the historical context in which the reinforcer occurs.     

Blockchain Technology as an Institution of Property

This paper argues that the practical implementation of blockchain technology can be considered an institution of property similar to legal institutions. Invoking Penner's theory of property and Hegel's system of property rights, and using the example of bitcoin, it is possible to demonstrate that blockchain effectively implements all necessary and sufficient criteria for property without reliance on legal means. Blockchains eliminate the need for a third‐party authority to enforce exclusion rights, and provide a system of universal access to knowledge and discoverability about the property rights of all participants and how the system functions. The implications of these findings are that traditional property relations in society could be replaced by or supplemented with blockchain models, and implemented in new domains.     

词语型类别属性归纳中分类与属性推理过程的时间特征

先前的研究中没有清晰分离类别属性归纳任务中分类过程与属性推理过程的ERP特征。本研究采用了事件相关电位技术(ERPs), 通过在词语型类别属性归纳任务的结论呈现阶段分开呈现结论类别和结论属性, 探讨了类别属性归纳中分类过程和属性推理过程的ERP特征。实验结果显示：在结论类别呈现阶段, 结论无关类别比结论关联类别诱发了更大的N400, 表明N400与类别属性归纳中的语义分类过程密切相关。在结论属性呈现阶段, 无论是在类别关联还是在类别无关条件下, 不一致属性比一致属性均诱发了更大的前部N2成分, 反映了属性知觉上的失匹配或规则的违背。随后, 在300~400 ms的时间窗口发现, 一致属性比不一致属性在前部脑区诱发了更大的类似于P3a的正偏转, 反映了对一致属性的更多关注。同时, 实验还发现, 当结论类别与前提类别关联时, 在300~400 ms的时间窗口, 一致属性比不一致属性在后部脑区也诱发了更大的类似于P3b的正偏转, 反映了推理预期的满意程度; 随后, 在400~600 ms的时间窗口, 不一致属性比一致属性在后部脑区诱发了更大的正偏转, 这与推理规则的违反相关。

关于人工语法学习迁移效应的一项实验研究

本研究探讨了人工语法迁移效应产生的机制,着重考查了组块信息迁移理论对人工语法迁移效应机制解释的适宜性。结果发现：当学习和测验序列的表层结构不同时,被试能够学习和迁移非重复成分间的序列依存性(实验一);当被试将非重复成分间的序列依存性迁移到表层结构不同的测验序列中时,需要在学习和测验序列的分布特征上形成一种匹配(实验二)。     

Inquiry into the Transcendence of Tang Dynasty Confucians to Han Dynasty Confucians and the Transformation of Traditional Confucianism in Terms of Lunyu Bijie

Neo-Confucianism of the Han and Tang dynasties is an indispensable part of the history of Chinese philosophy. From Han dynasty Confucians to Tang dynasty Confucians, the study of Confucian classics evolved progressively from textual research to conceptual explanation. A significant sign of this transformation is the book Lunyu Bijie 论语笔解 (A Written Explanation of the Analects), co-authored by Han Yu and Li Ao. Making use of the tremendous room for interpretation within the Analects, the book studied and reorganized the relationship between “the study of literature” and “the Dao and principles.” It clearly shows an inevitable development of Confucianism, shifting its focus from phenomena to the nature of the heart-mind in order to comprehend nature and heavenly Dao, both of which “cannot be heard (from Confucius).”     

Bochenski on Property Identity and the Refutation of Universals

An argument against multiply instantiable universals is considered in neglected essays by Stanislaw Lesniewski and I.M. Bochenski. Bochenski further applies Lesniewski’s refutation of universals by maintaining that identity principles for individuals must be different than property identity principles. Lesniewski’s argument is formalized for purposes of exact criticism, and shown to involve both a hidden vicious circularity in the form of impredicative definitions and explicit self-defeating consequences. Syntactical restrictions on Leibnizian indiscernibility of identicals are recommended to forestall Lesniewski’s paradox.
