Reward history modulates visual attention in an avian model

Animal Cognition - Attention can be biased towards previously reward-associated stimuli even when they are task-irrelevant and physically non-salient, although studies of reward-modulated attention...     

Modelling multiple problem-solving strategies and strategy shift in cognitive diagnosis for growth

Problem-solving strategies, defined as actions people select intentionally to achieve desired objectives, are distinguished from skills that are implemented unintentionally. In education, strategy-oriented instructions that guide students to form problem-solving strategies are found to be more effective for low-achieving students than the skill-oriented instructions designed for enhancing their skill implementation ability. Although the existing longitudinal cognitive diagnosis models (CDMs) can model the change in students' dynamic skill mastery status over time, they are not designed to model the shift in students' problem-solving strategies. This study proposes a longitudinal CDM that considers both between-person multiple strategies and within-person strategy shift. The model, separating the strategy choice process from the skill implementation process, is intended to provide diagnostic information on strategy choice as well as skill mastery status. A simulation study is conducted to evaluate the parameter recovery of the proposed model and investigate the consequences of ignoring the presence of multiple strategies or strategy shift. Further, an empirical data analysis is conducted to illustrate the use of the proposed model to measure strategy shift, growth in skill implementation ability and skill mastery status.     

青少年的移情与亲社会行为的关系

本实验研究选用的被试是144名12-16岁的中学生。研究采用自然实验与量表问卷相结合的方法。 实验结果表明,青少年的移情能力与亲社会行为呈显著的正相关。对实验班施予我们自己设计的“移情训练系列法”能明显提高他们的移情能力,增强亲社会行为。这一技术在青少年思想品德教育中具有实用性价值。 本实验研究只是一种初步的尝试,需要逐步展开,不断深化。     

Post-extinction conditional stimulus valence predicts reinstatement fear: Relevance for long-term outcomes of exposure therapy

Exposure therapy for anxiety disorders is translated from fear conditioning and extinction. While exposure therapy is effective in treating anxiety, fear sometimes returns after exposure. One pathway for return of fear is reinstatement: unsignaled unconditional stimuli following completion of extinction. The present study investigated the extent to which valence of the conditional stimulus (CS+) after extinction predicts return of CS+ fear after reinstatement. Participants (N = 84) engaged in a differential fear conditioning paradigm and were randomised to reinstatement or non-reinstatement. We hypothesised that more negative post-extinction CS+ valence would predict higher CS+ fear after reinstatement relative to non-reinstatement and relative to extinction retest. Results supported the hypotheses and suggest that strategies designed to decrease negative valence of the CS+ may reduce the return of fear via reinstatement following exposure therapy.     

Perceived similarity, proactive adjustment, and organizational socialization

The present study explores how perceived demographic and attitudinal similarity can influence proactive behavior among organizational newcomers. We propose that newcomers who perceive themselves as similar to their co-workers will be more willing to seek new information or build relationships, which in turn will lead to better long-term adjustment. Results from a three-wave field investigation of newcomer proactive behavior show that newcomer perceptions of surface-level similarity to the rest of the work group in education and gender increased proactive adjustment behavior. Contrary to our expectations, perceived similarity in terms of age decreased proactive adjustment behavior—in other words, newcomers who were significantly different from their co-workers in age engaged in more proactive adjustment behaviors. Deep-level similarity in terms of work style was associated with higher levels of role clarity, but this relationship was not mediated by proactive adjustment behavior.     

具身认知的“七宗罪”

近二十年来,具身认知已逐渐成为认知科学研究的主流趋势,其理论主张已经辐射到心理学、哲学、语言学、计算机科学等许多领域,研究成果运用范围逐渐扩大。诚然,具身认知在某种程度上弥补了“离身”认知的不足,但其在方法论和认识论方面的问题也日益突显,如循环论证,解释不充分,完全的二元对立,文化、社会、语言因素的忽视等。因此,当务之急是改进研究方法,摒弃先入之见,使其真正成为多角度、全方位、综合性研究。     

《鬼谷子》的“阴阳”思想与“说谋”论证

"阴阳"是纵横家论证理论的重要依据。以往的研究虽有关注"阴阳"的重要性,但未能解答纵横家如何运用"阴阳"思想生成相应论证理论这一问题,也没有深入探索纵横家将"阴阳"作为其理论依据的原因。基于此,在广义论证的研究视域下,以《鬼谷子》为研究对象,分析其中"阴阳"的哲学内涵以及"阴""阳"之间的关系;揭示"阴阳"对其论证理论的影响:"说"(说服)"谋"(谋略)作为纵横家论证理论的核心范畴,"说"有"捭阖""反应"等论证规则,"谋"作为论证主张,有"阴谋""阳谋"之分;解释纵横家以"阴阳"为据的原因,认为这与当时国君崇尚"用间(间谍)"的社会文化背景密切相关;探索"说谋"论证理论与春秋论证实践之渊源。     

对伦理学历史演变轨迹的一种概述(上)

最早产生的伦理学理论主要是目的论的.超验目的论、幸福论、快乐主义是它的重要形式.效用主义是快乐主义的一种较晚近的形式.德性伦理学也是最早产生的一种目的论伦理学.中国儒家学说在其核心处是一种德性的伦理学.在斯多亚学派的学说中,德性与至善概念疏离后成为目的本身.在西方,德性伦理学又由于它具有的不同特点被称为完善论或自我实现论.从德性伦理学中逐步分离出独立的正当概念.康德在许多方面来说是从德性伦理学到义务论伦理学的联系环节.在义务论伦理学中正当(应当)成为核心的概念.在义务论伦理学中,基于对正当的不同解说,形成责任论与权利论两脉.康德学说是责任论的杰出典范.在权利论中,首先形成作为其古代先声的回应的近现代契约论伦理学.从这种传统中新近发展出程序论的伦理学.     

从《太平经》看早期道教的孝道思想

孝道思想是道教的重要内容,其产生时间较早,并受到道教产生前背景观念的影响。道教早期文献《太平经》具有大量道教孝道思想的表达,并且具有代表性。本文通过对早期道教孝道思想产生的背景和对《太平经》文本的分析,得出道教早期孝道思想两重意蕴,即世俗层面和神圣层面,并指出道教孝道思想的最终落脚点在效法天地、顺其自然。     

Lay theory of race affects and moderates Asian Americans' responses toward American culture

People may hold different understandings of race that might affect how they respond to the culture of groups deemed to be racially distinct. The present research tests how this process is moderated by the minority individual's lay theory of race. An essentialist lay theory of race (i.e., that race reflects deep-seated, inalterable essence and is indicative of traits and ability) would orient racial minorities to rigidly adhere to their ethnic culture, whereas a social constructionist lay theory of race (i.e., that race is socially constructed, malleable, and arbitrary) would orient racial minorities to identify and cognitively assimilate toward the majority culture. To test these predictions, the authors conducted 4 studies with Asian American participants. The first 2 studies examine the effect of one's lay theory of race on perceived racial differences and identification with American culture. The last 2 studies tested the moderating effect of lay theory of race on identification and assimilation toward the majority American culture after this culture had been primed. The results generally supported the prediction that the social constructionist theory was associated with more perceived similarity between Asians and Americans and more consistent identification and assimilation toward American culture, compared with the essentialist theory.
