社会认同对抑郁的影响及其理论解释

社会认同作为个体在群际和内群体层面的社会联结,总体上对抑郁产生了积极影响,表现为认同程度、认同重要性、认同群体数量以及认同变化的影响等4个方面。现有研究从需求、认知和行为层面探讨了社会认同影响抑郁的中介因素,并检验了身份认同动机和消极群体评价两个调节因素。社会认同视角下的4种理论分别从社会医治、心理资源、认同变化以及认同层次等不同角度解释了社会认同影响抑郁的心理机制。未来应厘清社会认同对抑郁的深层影响机制,重视社会认同影响抑郁的调节因素,及建构社会认同影响抑郁的能动-共生模型。     

Constraints on the visual accuracy of drawings produced by young children

Errors made by young children when they are asked to draw a model were investigated in two studies. In the first study, the experimenter asked 5- and 8-year-old children to draw a cup that had a flower decal (transfer) attached to its outside surface, attached to its inside surface or positioned beside it. The 8-year-old children in all conditions produced visually accurate drawings. The 5-year-old children produced visually accurate drawings when the flower decal was positioned beside the cup and when the flower decal was attached to the inside surface of the cup but not when the flower decal was attached to the cup's outside surface. In the second study, 5- and 8-year-old children were asked to draw a cup that had either an intact or a broken handle. The handle area of the cup was either in view or not in view. The 5- and 8-year-old children performed comparably in this experiment. The children had difficulty producing accurate copies of the model only when the cup had a handle and the handle was not in view. Taken together, these studies indicate that 5-year-old children are more likely to produce visually accurate drawings than has previously been supposed. Difficulty in producing accurate drawings occurred when drawing rules and drawing conventions interfered with the task.     

汉语颠倒词加工中重复知盲发生的水平

以汉语中的颠倒词为材料, 探讨汉语重复知盲的发生水平。采用RSVP方式呈现包含颠倒词对(C1和C2)的句子列表或词语列表, 让被试对列表中的词进行全部报告或报告是否存在重复词, 记录报告C2的正确率。三个实验采用3 (词语的重复性: 颠倒重复、完全重复、不重复) × 2 (颠倒词对的意义相似性: 意义不同、意义相似)两因素被试内设计, 结果在全部报告和报告是否存在重复词的实验中都出现重复性和意义相似性的交互效应, 但不同实验任务, 数据模式不同。该结果表明, 在RSVP任务中, 汉语颠倒词加工存在RB效应, 该效应产生的水平受制于不同的实验任务, 在部分报告任务中, 颠倒词的RB效应发生在知觉水平, 在全部报告任务中, 颠倒词的RB效应发生在语义水平。     

线索呈现的时空特性对表征动量的影响

为揭示注意对表征动量的影响机制,我们结合线索提示和表征动量范式,通过两个实验比较高、低相关线索分别在诱导期间与保持间隔呈现对表征动量的影响,结果发现：(1)高相关线索的时间特性主效应不显著,最终位置均发生边缘性的向前偏移。(2)低相关线索呈现在诱导期间时,表征动量显著;呈现在保持间隔时,发生向后偏移。这些表明,随着注意增大,表征动量减小;高相关线索更有利于定位,而低相关线索易受时间特性的影响。研究结果验证表征动量的双加工理论。     

不同特征维度下ADHD儿童的任务切换特点

本研究采用双向刺激设置,通过操纵两实验的特征维度,以考察任务维度对ADHD儿童任务切换的影响。结果发现,在两个实验中,相对于正常组儿童,ADHD儿童在任务切换上都表现出缺损。当注意维度相同时,ADHD儿童在固定顺序上的切换损耗大于随机顺序,但在跨维度任务中,ADHD儿童在固定顺序上的切换损耗则小于随机顺序,这与正常儿童的表现模式不一致。该结果表明,工作记忆会对ADHD儿童产生影响,但这取决于任务的特征维度是否一致。     

题库结构对原始题在线属性标定准确性之影响研究

目前已有研究证明可达阵在认知诊断测验编制中起重要作用,但迄今为止并没有引起普遍注意。本文主要讨论当题库缺少某些可达阵对应的项目类,对原始题的属性向量在线标定的准确性的影响。本文对含6个属性的独立型结构进行了模拟试验,结果显示：如果题库不充要,原始题的属性标定准确性受到影响,题库中非可达阵中项目对标定有一定的弥补作用。间接印证了可达阵在认知诊断题库起到非常重要的作用。     

Why it is difficult to see the anima as a helpful object: critique and clinical relevance of the theory of archetypes

This paper is divided into three parts. The first deals briefly with more general aspects of the theory of archetypes (as conceived by Jung); the second examines the anima archetype in rather more detail, because it is, apart from the self, the main archetype in Jung's thought; and the third discusses the clinical repercussions of the anima theory and of the theory of the archetypes in general. The various references to Jung himself and certain circumstances of his life are included here on the assumption that personal problems in his biography contributed decisively to the constitution of his theory, so that deeper insights accure if they are taken into account.     

On Categorical Equivalences of Commutative BCK-algebras

A commutative BCK-algebra with the relative cancellation property is a commutative BCK-algebra (X;*,0) which satisfies the condition: if a ≤ x, a ≤ y and x * a = y * a, then x = y. Such BCK-algebras form a variety, and the category of these BCK-algebras is categorically equivalent to the category of Abelian ℓ-groups whose objects are pairs (G, G ₀), where G is an Abelian ℓ-group, G ₀ is a subset of the positive cone generating G ⁺ such that if u, v ∈ G ₀, then 0 ∨ (u - v) ∈ G ₀, and morphisms are ℓ-group homomorphisms h: (G, G ₀) → (G′,G′₀) with f(G ₀) ⫅ G′₀. Our methods in particular cases give known categorical equivalences of Cornish for conical BCK-algebras and of Mundici for bounded commutative BCK-algebras (= MV-algebras).

门脉高压症治疗观点之辩

对立统一规律是辩证法的实质,在唯物辩证法的理论体系中占有核心地位。门脉高压症的外科治疗有分流术与断流术两种不同的手术方法,这两种方法从治疗机制上看是矛盾的,用对立统一观来认识这两种手术的联系并揭示门脉高压外科治疗发展的哲学依据。     

大学新生学科选择结果与人格特征关系的研究

该研究对17个系的1532名大学新生专业学科与其人格特点的关系用聚类分析和多元方差分析的方法进行了探索研究.聚类分析结果将男生根据人格特点分为理工科类、社会科学类中间科系"的特殊类.将女生也分为三大类,即与男生类似的社会科学类以及另外两类与学科分类隶属关系复杂的类别.男生对理工科和社会科学专业的选择结果与其人格特点有较明显的一致关系,而女生对社会科学专业的选择结果与其人格特点有较明显的一致关系.
