本研究采用开放式问卷法,通过调查810名6-14岁儿童头脑中想象物的文字与图画描述,考察了儿童想象发展的特点。结果发现:(1)儿童对想象物的文字与图画描述可以分划分为3种水平:表象的记忆水平、表象的再造水平和表象创造水平。其中,对想象物的文字描述水平,年龄发展趋势明显,从小学一至二年级之间和四到五年级之间的发展变化最大;而对想象物的图画描述水平,年龄发展趋势不明显。(2)根据儿童对想象物的文字描述和图画描述的发展的匹配程度,可以把儿童的想象发展分为3种类型:文字与图形符号均衡发展型、文字符号型和图形符号型。 相似文献

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。 相似文献

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. 相似文献

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。 相似文献

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. 相似文献

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 总被引:1,自引:0,他引:1
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。 相似文献
