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)。     

Impulse processing: a dynamical systems model of incremental eye movements in the visual world paradigm

The Visual World Paradigm (VWP) presents listeners with a challenging problem: They must integrate two disparate signals, the spoken language and the visual context, in support of action (e.g., complex movements of the eyes across a scene). We present Impulse Processing, a dynamical systems approach to incremental eye movements in the visual world that suggests a framework for integrating language, vision, and action generally. Our approach assumes that impulses driven by the language and the visual context impinge minutely on a dynamical landscape of attractors corresponding to the potential eye-movement behaviors of the system. We test three unique predictions of our approach in an empirical study in the VWP, and describe an implementation in an artificial neural network. We discuss the Impulse Processing framework in relation to other models of the VWP.     

Flicker-light induced visual phenomena: frequency dependence and specificity of whole percepts and percept features

Flickering light induces visual hallucinations in human observers. Despite a long history of the phenomenon, little is known about the dependence of flicker-induced subjective impressions on the flicker frequency. We investigate this question using Ganzfeld stimulation and an experimental paradigm combining a continuous frequency scan (1–50 Hz) with a focus on re-occurring, whole percepts. On the single-subject level, we find a high degree of frequency stability of percepts. To generalize across subjects, we apply two rating systems, (1) a set of complex percept classes derived from subjects’ reports and (2) an enumeration of elementary percept features, and determine distributions of occurrences over flicker frequency. We observe a stronger frequency specificity for complex percept classes than elementary percept features. Comparing the similarity relations among percept categories to those among frequency profiles, we observe that though percepts are preferentially induced by particular frequencies, the frequency does not unambiguously determine the experienced percept.     

Cognitions associated with recovery from alcohol dependence1

The present study examined the cognitive factors uniquely associated with the status of alcohol dependence recovery, assessing Korean patients who were recovered (n = 57), having been alcohol‐abstinent for 4 months or more after treatment, and who were nonrecovered (n = 213), being still in treatment. Compared with the nonrecovered group, the recovered group reported lower levels of denial of drinking problems and rationalization of drinking (two dimensions of specific beliefs that facilitate alcohol use), dysfunctional attitudes, depressed mood, and emotion‐focused coping. The recovered group also showed higher levels of alcohol abstinence self‐efficacy and problem‐focused coping. Both denial and alcohol abstinence self‐efficacy were uniquely associated with alcohol dependence recovery, when we controlled for the other relevant predictors, whereas neither dysfunctional attitudes nor rationalization were so associated. These findings could be useful in refining psychological interventions facilitating the recovery of alcohol‐dependent patients.     

社会公正与政治信任：民众对政府的合作行为机制

胡锦涛在中共十八大上提出：必须坚持维护社会公平正义。对社会公正的认知直接决定着民众的政治信任, 进而影响民众对政府的合作。近年来频发的群体性事件即是非合作行为的典型表征。然而, 国内外研究中至今没有直接探讨社会公正与政治信任影响合作行为的实证支持, 更无法进一步揭示其作用于合作行为的过程和条件。鉴于此, 本研究将社会公正分为分配公正和程序公正, 将政治信任分为工具信任和情感信任, 采用实验室研究、现场研究和问卷调查研究相结合的方法, 探讨社会公正对合作行为的过程机制, 建立其通过工具信任和情感信任作用于合作行为的双路径模型; 并进一步分析结果依赖性对这一路径模型的调节作用。本研究有望提出社会公正与政治信任影响合作行为的双路径模型及其调节变量, 一方面在理论上深化和拓展本领域的研究, 另一方面实践中通过提升公正感、强化过程变量(政治信任)、干预调节变量(结果依赖性)等策略促进合作行为。     

心理学视角下的极端膜拜伤害问题

对极端膜拜团体造成身心伤害现象的科学研究, 集中在对极端膜拜伤害的界定、测量和机制三个方面。本文的目的, 是梳理这三个主题上的研究脉络, 明晰其中的争议之处和取得的成绩。文本分析表明, 对极端膜拜伤害的界定从“洗脑”转向了“心理虐待”, 对这类伤害的经验观察由个体症状转向了群体行为和经历的描述, 测量方法由传统心理测试工具变成了新型团体心理虐待量表, 膜拜伤害的心理机制研究在综合环境和个人精神特质两种因素的基础上建立了二者交互的病理模型, 表观遗传学和人际神经生物学用于极端膜拜伤害的生理机制研究已见端倪。但是, 迄今对于极端膜拜伤害的学术研究尚未形成范式。     

酒依赖与酒文化

作为一种精神障碍,越来越多的与饮酒有关的问题在我国引起了专业人员的重视。酒依赖不仅对个体的心理和躯体健康有害,还会引起一系列的社会问题。对酒这种精神活性物质作了多维度的评价,描述了形形色色的酒文化现象,探讨了我国酒文化在饮酒及饮酒相关问题发生中的作用。     

Right hemispatial neglect: frequency and characterization following acute left hemisphere stroke

The frequency of various types of unilateral spatial neglect and associated areas of neural dysfunction after left hemisphere stroke are not well characterized. Unilateral spatial neglect (USN) in distinct spatial reference frames have been identified after acute right, but not left hemisphere stroke. We studied 47 consecutive right handed patients within 48h of left hemisphere stroke to determine the frequency and distribution of types of right USN using cognitive testing and MRI imaging. The distribution of USN types was different from the previously reported distribution following acute right hemisphere stroke. In this left hemisphere stroke population, allocentric neglect was more frequent than egocentric neglect.     

司法论证充分性辨析

司法论证充分性问题是一个和法学理论与司法实践都密切相关的问题,各种关于法律论证的争议是和规则治理与纠纷解决两种司法职能的互相冲撞息息相关的。什么样的法律论证才是最合适的,在法律资源有限的情况下,如何运用有限的资源达到司法实践的目的,是各国法制建设的一个永恒话题。文章试图以我国的司法情景为例,从理性思考与现实实践两个层面,展示法官在裁决中所运用的具有地方性知识性质的辅助资源具有实践合理性,说明司法论证应该也必须追求其充分性。
