视觉表象生成系统及其影响因素

视觉表象是在记忆基础上产生的类似知觉的信息表征, 也是人们在日常生活中不可或缺的心理活动之一。本综述介绍了该领域中比较有影响力的表象计算理论模型, 并进一步归纳了视觉表象生成系统的成分及其对应的神经基础。分析结果强调了初级视觉皮层作为“视觉缓冲器”是生成表象的主要机能结构, 以“视觉缓冲器”为基础的表象生成系统的机能受多重因素影响。本综述有助于对视觉表象生成系统形成全面的认识, 促进视觉表象实质的进一步研究。     

依恋差异对自传记忆加工的影响

自传记忆是个体对过去生活事件的记忆, 是自我系统形成、发展和变化的基础, 对维持自我同一性和连续性具有重要意义。自传记忆的形成是一个建构过程, 依恋可能通过概念性自我系统和工作自我目标系统两种途径影响自传记忆的加工。依恋与自传记忆加工的已有研究主要集中于个体依恋特征及亲代依恋特征分别与自传记忆客观性特征、现象学特征、叙事特征及重构特征之间的关系。未来研究应聚焦依恋影响自传记忆加工的心理和神经机制, 增加不同社会文化情境、不同发展阶段亲代依恋特征和子代自传记忆加工的相关研究, 并使用启动范式、静息态成像技术、感知相机等变量控制更加严格、更具生态效度的研究方法。     

系统合理化何以形成——三种不同的解释视角

系统合理化理论认为, 人们会自然地将其所在的社会系统感知为公平合理的, 这一倾向即系统合理化。而系统合理化形成之原因, 一直是该领域理论和研究关注的重点。为此, 研究者先后提出了三种解释思路。认知失调视角认为, 系统合理化之所以产生是因为个体想要缓解因系统无法满足他们的需求而产生的焦虑。补偿性控制视角认为, 系统合理化源于个体自身控制感的缺乏。社会认知视角则认为人们固有的认知倾向特别是对于社会经济差异的内归因倾向是造成系统合理化的根源。未来可以考虑在同一个研究中包含来自于不同理论视角的解释变量, 借鉴相近领域的发现探索其他可能存在的系统合理化的形成机制, 探究中国文化特有的系统合理化的来源, 同时对积极的合理化与消极的合理化作出区分, 并在此基础上针对社会现实问题加强应用研究的开展。     

A formal framework for modelling the developmental course of competence and performance in the distance,speed, and time domain

The developmental course in the distance–speed–time domain is still a matter of debate. Traditional stage models are contested by theories of continuous development and adaptive thinking. In the present work, we introduce a formal framework for modelling the developmental course in this domain, grounding on Competence-based Knowledge Space Theory. This framework, as a more general case, widely includes assumptions and facets of previous models and covers empirical findings collected based on different experimental paradigms. By a distinction of latent competences and observable performance, model validation is not bound to a certain experimental paradigm and no one-to-one correspondence between competences and tasks is required. Therefore, the framework has the potential to bridge the gap between stage models and models of continuous development. The approach also precisely defines misconceptions, for example overgeneralization, and empirically investigates their occurrence. In the present work, we established a prototypical model for the development of understanding the distance–speed–time system. We extended this model with definitions based on different perspectives of overgeneralization. The assumptions of the model and its extensions were examined on the basis of the results of two empirical investigations using six judgment task types. The results yielded a reasonably good fit of model and data. No evidence was found for the occurrence of overgeneralization in this domain. The theoretical model and empirical results are discussed with respect to their relationship to other developmental models and theories.     

Sympathetic arousal to a vestibular stressor in high and low hostile men

The aim of the present experiment was to extend the literature on hostility and a cerebral systems based model of sympathetic arousal to a vestibular-based stress. Several authors have concluded that autonomic stress reactivity in high hostile individuals must be interpersonally based, whereas healthy vestibular system functioning does not depend on interpersonal features. Utilizing a vestibular activation paradigm, skin conductance levels of 15 high hostile and 15 low hostile men were recorded after brief passive rotation about the vertical neuroaxis. It was expected that hostile individuals would exhibit higher skin conductance levels after rotation compared with low hostile individuals. The results confirmed expectations of heightened sympathetic tone among high hostiles subsequent to vestibular stress. Overall, the findings are interpreted to support a cerebral model of frontal region capacity limitation for regulation of vestibular stress that is independent of psychosocial mechanisms.     

Evaluating dialectical structures with Bayesian methods

This paper shows how complex argumentation, analyzed as dialectical structures, can be evaluated within a Bayesian framework by interpreting them as coherence constraints on subjective degrees of belief. A dialectical structure is a set of arguments (premiss-conclusion structure) among which support- and attack-relations hold. This approach addresses the observation that some theses in a debate can be better justified than others and thus fixes a shortcoming of a theory of defeasible reasoning which applies the bivalence principle to argument evaluations by assigning them the status of being either defeated or undefeated. Evaluation procedures which are based on the principle of bivalence can, however, be embedded as a special case within the Bayesian framework. The approach developed in this paper rests on the assumptions that arguments can be reconstructed as deductively valid and that complex argumentation can be reconstructed such that premisses of arguments with equivalent conclusions are pairwise independent.     

BTL—QZ—V1．1气质测试系统的修订

修订BTL-QZ-V1．1气质测试系统。对519名12—21岁男女学生进行了测量。结果发现：神经系统特性具有年龄差异,随年龄增长兴奋性、抑制性增强,灵活性、稳定性增高;12～14岁是其快速增长期,14～18岁为慢速增长期,18岁后为稳定期;神经系统的兴奋性、抑制性具有性别差异,男生强于女生;可将气质类型划分为10种,年龄和性别不影响气质类型的分布;除灵活性外,神经系统兴奋性、抑制性和稳定性的重测信度系数在0．6～0．8之间,且达到显著性水平;以80·8神经类型量表为效标,所得相关系数达中等程度。提示BTL-QZ-V1．1气质测试系统的评定需按年龄和性别分组进行,建立的分组标准较为准确科学,信度、效度较高,可以广泛应用。     

自闭症谱系障碍儿童心理测评的回溯与探索

自闭症谱系障碍(ASD)儿童是一群已引起高度关注的群体,因其兼具社会发展、人际交流障碍等于一身,更因其中大部分儿童还伴有认知,言语发展和情绪障碍,对其进行心理测评是一个极为艰巨和重要的课题.本文从诊断性、认知性和教育干预三个方面对ASD儿童的心理测评进行了述评.同时还阐述了在此基础上建构"会聚式"、"分层式"和"分类式"ASD儿童心理测评体系之构想.     

Communication and Cognition: The Social Beyond Language,Interaction and Culture

Cognition theories describe the social with terms like language, interaction or culture, whose theoretical status has also been discussed in modern sociology. These concepts are not well-positioned to understand the emergence and autonomy of social orders. Sociological theory of self-referential systems can be useful to reconstruct the bottom-up process which contributes to the emergence of the social as communication as well as to describe the way in which society exerts downward causation upon cognitive phenomena. The core of this theory is the systemic category of meaning as a shared horizon for psychic and social systems.
