焦虑性神经症的认知和躯体感觉研究

从Ｓｃｈａｃｈｔｅｒ的二因素理论和Ｂｅｃｋ的认知模式观点出发,采用信念量表、广场恐怖认知问卷、躯体感觉问卷、Ｈａｍｉｌｔｏｎ焦虑及抑郁量表,以抑郁患者和正常人两组作对照,调查了焦虑患者的焦虑、认知及躯体感觉的相互关系。初步结论是,“躯体损害性”自动想法和对躯体感觉的过分担心是临床焦虑的特征;“社会、行为后果性”想法似乎是焦虑和抑郁患者共有的。焦虑的认知内容是以“危险”为主题的,躯体感觉和认知错解在焦虑发生发展中起重要作用。“危险”的负性自动想法和焦虑关系密切,而由非理性信念所反映的特定的认知图式可能促使患者过度夸大危险性。这一结果在一定程度上支持了两因素理论和Ｂｅｃｋ的认知模式     

内隐态度实验研究:加工水平与黄,白,黑情感态度

研究使用肯定词和否定词分别与黄、白、黑三字搭配的实验卡片。随机抽取医学院本科生34名,采用2种加工水平×3种测量目标的混合设计来考察态度情感特征的无意识性。结果发现：1）加工水平对被试的自我报告和线索提取有不同的影响,即自我报告受加工水平影响,线索提取不受加工水平影响,发生实验性分离;2）加工水平对被试态度的实验性分离也有不同影响,即概念加工下出现高度分离,数据加工下则低度分离,3）经过改造的语义线索法是测量内除态度的有效方法。     

“心理距离“在后悔加工中作用的初步研究

采用改编的虚构故事,通过240名大学生课堂实验的形式,对假设思维中涉及的最佳状态和理想状态之间的心理距离是影响后悔强度的主要因素的假设进行检验。结果部分支持了该假设。同时表明,心理距离外的其它因素,如“孤岛效应”也对后悔加工有较大的影响。另外,对后悔的后加工观进行了检验,为后悔的研究从实验室转向现实生活辅平了道路。     

Teachers' Ratings of Attention-Deficit Hyperactivity Disorder and Decisions for Referral for Services in Taiwan

We examined the relationship between elementary teachers' perceptions and ratings of Attention-Deficit Hyperactivity Disorder (ADHD) symptoms of students and their referral decisions in public schools in Taiwan. One hundred and twenty-one homeroom teachers were randomly selected from six public elementary schools in Taipei County, Taiwan, to participate in the study. The study contained two groups of children, a random sample (n — 478) and a nominated sample (n = 219). Results of the discriminant analyses showed that Chinese teachers' ratings of ADHD could predict group membership as to whether a student had been or might be referred. This study found that, despite the fact that Chinese teachers believed children with scores two standard deviations above the mean had behavior problems, teachers decided not to refer those students. Teachers were more likely to refer children whose scores were three standard deviations above the mean.     

An expanded etiological model for suicide behavior in adolescents: Evidence for its specificity relative to depression

This study tests both the stress/social support and the stress/problem-solving etiological models for suicidality while controlling for depression. To this end, a depressed, high-suicide-ideating sample (N=68) was compared to a depressed, low-suicide-ideating sample (N=64). Hierarchical multiple regression analyses were used to test the unique contributions of stress, problem-solving orientation, problem-solving skills, and perceived level of social support in predicting level of suicidality. Hierarchical regression analyses were also used to test the interactive contributions of problem-solving × stress and social support × stress in predicting level of suicidality. Regression models were generated separately for men, women, and the entire sample using all factors. The results clearly support the importance of social support as an independent predictor of suicidality for men, women, and the entire sample. Ability to generate alternatives to identified problems predicted suicidality, but only for women and the entire sample. Problem-solving orientation was not uniquely predictive of suicidality and may affect suicidal behavior via its relationship to depression.     

Menninger's motives for suicide in the notes of completed and attempted suicides.

Brevard, Lester, and Yang in 1990, studying Menninger's motives for suicide, reported more evidence for the wish to be killed (i.e., self-blame or self-punishment) in suicide notes for completed suicides than in parasuicide notes for attempted suicide; however, they did not control for age and sex. A comparison of notes written by completed and attempted suicides that controlled for age and sex showed no differences in the presence of content which reflected Menninger's three motives for suicide, including the wish to be killed.     

精神分裂症病人对成人面部表情的辨别

本文对比研究了精神分裂症病人和正常人对成人面部表情辨别的水平,发现精神分裂症病人存在着表情辨别障碍。病程长、以阴性症状为主的病人易出现这种障碍。表情辨别障碍是一种情绪障碍,属阴性症状。     

动觉后效的个体差异

本实验对143人用宽、窄两种插入刺激测定了动觉后效。实验结果表明,缩小型属外向,扩大型属内向,中间型内外向的趋势不大明显。作者简化了动觉后效的测定程序以后,并没发现对实验结果有什么影响,但发现了在各种条件下测定的动觉后效的类型是稳定不变的。这些都是把它作为诊断内外向的指标的有利条件。     

吗啡成瘾的大鼠行为改变及其与脑内单胺类神经介质含量变化的关系

本文以64只大鼠为材料,采用饮服和腹腔注射吗啡的方法,建立大鼠对吗啡成瘾性的实验模型,观察它们的行为改变和脑内单胺类神经介质含量的变化,结果发现:两种方法都可使大鼠成瘾,成瘾时间在给药后的第四周左右形成;成瘾后的大鼠对药物产生明显的依赖性,每天对吗啡的摄取量大致稳定在35mg/kg左右;如突然停药大鼠表现出不安静状态,活动增加,体重下降;食物运动性条件反应的反应时与戒断前相比明显缩短,错误次数减少;成瘾后的大鼠脑内单胺类神经介质的含量也发生改变,NE和DA有所下降,而5-HT和5-HIAA则显著升高,对于这种变化是原发性的还是继发性的还需进一步研究。     

Retroactive inhibition without intentional new learning: Some comment on the elicitation hypothesis

Two groups of subjects learned a list of paired-associates. Subsequently, an interpolated phase was introduced that did not require the acquisition of a new PA-list. The experimental group had to fulfill a number of little tasks with respect to the first terms of the previously learned list, whereas the control group did the task with words which were not on that list. In two experiments it was shown that when the retention of the learned associates was tested, the experimental group suffered more from forgetting than the control group. It is concluded that new learning is not a prerequisite in the induction of RI. The position of the elicitation hypothesis of Two Factor theory is critically discussed and the evocative disuse hypothesis is presented as an alternative conception with respect to the phenomenon of interference.
