Transitional object use,attachment, and help‐seeking behaviour in Taiwanese adolescents

Transitional object use is psychologically beneficial for young children, but research has suggested that maintaining transitional object use into middle childhood may be associated with negative behaviour. Little is known about the continuation of transitional object use into adolescence, and few studies have been conducted with non‐Western populations. To examine differences in attachment and attitudes to help seeking in adolescents who did and did not use a transitional object, 723 adolescents from Taiwan (M age = 14 years) were asked about their current and past use of transitional objects. Measures of attachment were obtained using the Revised Adult Attachment Scale, and attitude toward help was measured using the Attitudes Toward Seeking Professional Psychological Help Scale. In total, 37% of the sample continued transitional object use in adolescence. Current use of a transitional object differentiated the sample on the measures of attachment and help seeking. Transitional object users were less likely to have secure attachments and less likely to express positive attitudes toward seeking help. Transitional object use is prevalent in Taiwanese adolescents, and we suggest that continued use of a transitional object acts as an indicator of potential withdrawal from support offered in schools.     

非文字内隐学习的优势效应

本研究以大学生为被试,运用计算机将人工语法范式程序化,分别以色块串和色词串为材料,研究颜色内隐和外显学习的特点;并增设时间变量（单元）以了解学习的详细进程。结果发现：1.学习材料上存在主效应,非言语材料（包块）较言语材料（色词）更适合于内隐加工。2.时间变量上也存在主效应,整体呈递增趋势;3.指导语上不存在主效应,即内隐学习在不同材料上的优势效应依然存在。实验结果极好地支持了非文字内隐学习优势效应的假设。     

初一学生英语单词记忆策略的训练研究

在初一学生英语单词学习中引入关键词和概念归类策略训练,探讨了记忆策略的训练效果和自我效能对英语单词记忆的影响。结果发现：两种策略训练都能显著提高初一学生英语单词扇一效果相近;关键词策略训练可显著提高低自我效能被试的自我效能感;记忆自我效能对英语单词记忆行为有显著影响,高自我效能被试在训练后英语单词记忆成绩更好。     

糖尿病患者白内障术后并发症的分析及处理

白内障超声乳化手术使得广大糖尿病患者术后获得了良好视力,但作为一个特殊高危群体,手术后并发症不容忽视.本文结合以往我科临床经验,按照发生率的高低,就糖尿病患者白内障术后并发症的发生情况作一剖析,并参照相关文献,讨论分析其发生的危险因素,及在临床工作中如何预防或减低糖尿病患者白内障术后并发症的发生几率,以期警示临床进一步加强围手术期管理制度,针对患者具体情况,依据临床专业理论和经验,作出最优化临床决策.     

条件反射性免疫抑制激活过程中下丘脑核团c-fos的表达

利用经典条件反射性免疫抑制的动物模型,以糖精水为条件刺激（CS）,免疫抑制剂-环磷酰胺为非条件刺激 （UCS）,观测两次CS-UCS结合训练后,再次条件刺激诱发条件反射性免疫抑制作用的动态改变,获得条件反射性免疫抑制和味觉厌恶性条件反射各自保持的情况,并在此基础上,采用c-fos免疫组化技术, 进一步观察再次条件刺激诱发条件反射性免疫抑制反应时大鼠下丘脑各核团内FOS蛋白的表达情况。结果表明,条件反射性免疫抑制作用在训练后第5天较强,第30天基本消失,而味觉厌恶性条件反射始终稳定保持到第30天。进一步研究显示出,下丘脑室旁核FOS蛋白表达在第5天非常密集,而第30天几乎没有表达,与细胞免疫功能改变在时程和趋势上具有一致性。通过FOS蛋白表达时程差异比较,提示下丘脑室旁核可能是CNS内介导CS诱导的免疫抑制效应的重要核团。     

Conditional Direction Dependence Analysis: Evaluating the Causal Direction of Effects in Linear Models with Interaction Terms

Abstract

Direction dependence analysis (DDA) makes use of higher than second moment information of variables (x and y) to detect potential confounding and to probe the causal direction of linear variable relations (i.e., whether x?→?y or y?→?x better approximates the underlying causal mechanism). The “true” predictor is assumed to be a continuous nonnormal exogenous variable. Existing methods compatible with DDA, however, are of limited use when the relation of a focal predictor and an outcome is affected by a moderator. This study presents a conditional direction dependence analysis (CDDA) framework which enables researchers to evaluate the causal direction of conditional regression effects. Monte–Carlo simulations were used to evaluate two different moderation scenarios: Study 1 evaluates the performance of CDDA tests when a moderator affects the strength of the causal effect x?→?y. Study 2 evaluates cases in which the causal direction itself (x?→?y vs y?→?x) depends on moderator values. Study 3 evaluates the robustness of DDA tests in the presence of functional model misspecifications. Results suggest that significance tests compatible with CDDA are suitable in both moderation scenarios, i.e., CDDA allows one to discern regions of a moderator in which the causal direction is uniquely identifiable. An empirical example is provided to illustrate the approach.     

乌特勒支恋家症量表在大学生中的信效度检验

为检验中文版乌特勒支恋家症量表在大学生群体中的信效度,使用样本1(n=1071),进行信效度检验与测量等值性,使用样本2(n=177,连续5期)检验跨时点的纵向测量等值性。结果表明中文版乌特勒支恋家症量表为五因子结构,包含想家、孤独、想念朋友、适应困难和关于家庭的沉思5个维度,具有良好的信效度、效标效度与测量等值性。意味该量表适合在我国大学生群体中使用,并能够用于跨性别、年级以及时点的相关研究。     

多个非线索化位置易代的一项实验研究

现在采用返回抑制范式所进行的空间非信息线索作用的研究,大多以非线索化位置反应时为参照,发现线索化位置的反应先易化后抑制。后者即返回抑制。本研究采用在返回抑制范式上增设中性线索化条件的方法,发现当靶子可以出现的位置为四个时,相对于中性线索化条件,非线索化位置反应快。这种非线索化位置的易化作用是独立存在的,它能使生物体尽快地对出现在多个非线索化位置的靶子作出反应。     

哀伤研究：新的视角与理论整合

哀伤（bereavement）研究长期以来都依循“悲伤过程假设（griefworkhypothesis）”,但20世纪80年代后其强调“与逝者分离”的基本假设受到挑战,界定的模糊也使得实证研究工作难以进行。当代研究者从依恋理论、创伤研究、认知应对研究、情感的社会功能等视角多方面对哀伤领域进行深入探索并出现了一些整合性的理论模型,文中对有代表性的“依恋与哀伤双程模型”作了介绍,并对“悲伤过程假设”进行了重新检视     

SSCI中自我表露研究的计量分析

采用文献计量学方法,利用SSCI对1975~2005年有关自我表露的文献进行统计分析,以揭示30年来自我表露研究主要涉及的学科领域、源期刊、研究者及其特点,特别将我国香港、台湾、大陆研究者的38篇本土研究进行了整理分析。从分析中可以看到我国本土研究虽然数量少,但研究热点、对象、方法等与国外研究基本一致,与此同时一些研究还关注到中国文化对表露的影响。从研究脉络来看,我国本土研究理论性有待加强
