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。     

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.     

关于闪光盲的研究——Ⅰ.闪光亮度、曝光时间和适应状态对闪光盲恢复时间的影响

在暗适应和在明适应(1×10~(-2)熙提)条件下,对11名正常视觉的男性受试者测定了闪光亮度、闪光时间对闪光盲恢复时间的影响。观察目标为6’视角的蓝道环缺口。结果表明:①在0.45—1.5熙提(暗适应条件)和2—36熙提(明适应条件)范围内,恢复时间与闪光亮度成线性关系。②关系曲线的斜率随闪光时间的加长而增大。③引起同样恢复时间的闪光盲,明适应时所需闪光亮度为暗适应时的3—5倍,实验结果可为防闪光盲护目镜减光倍率的确定提供参数。     

运动强度和持续时间对运动后过量氧耗的影响

本研究采用双因素实验设计探讨了运动负荷强度和持续时间对 E-POC的影响。实验结果发现 ,运动过程中机体净耗氧量主要取决于运动持续时间 ,而运动后的 EPOC既受运动强度 ,也受持续时间的影响 ,但以前者的作用更加明显 ;运动后 VO2 的恢复速度快于血乳酸的消除 ,不同运动条件下的氧亏量变化主要取决于运动负荷的强度。     

青少年学生自我价值感特点的初步研究

采用《青少年学生自我价值感量表》对初中一年级到大学四年级共２１８７名青少年学生进行问卷调查,结果发现：（１）不同年级的学生在总体自我价值感、社会取向和个人取得的自我价值感方面差异极显著。（２）男生个人取向的自我价值感显著高于女生,女生社会取向的自我价值感则显著高于男生;男生个人取向的道德价值感高于女生,女生的社会取向的道德价值感则高于男生。（３）重点中学的学生在总体自我价值感、社会取向和个人取向的自我价值感、个人取向的家庭价值感以及社会取向的心理价值感、家庭价值感方面均显著高于非重点中学的学生。     

Individualism and Authoritarianism Shape Attitudes Toward Physician-Assisted Suicide1

We investigated the relation between value orientations and attitudes toward physician-assisted suicide (PAS) in 267 United States college students. We predicted that individualistic values, especially those having to do with control and self-determination, would lead to favorable attitudes toward PAS, and authoritarianism would lead to a rejection of PAS. A positive association between individualism and approval of PAS emerged which was moderated by attitude importance: People who did not endorse individualistic values did not have favorable opinions of PAS, regardless of how important the issue was to them. However, for individualists, PAS attitudes and attitude importance were positively related. Independent of individualism, authoritarianism was negatively related to PAS attitudes. Primarily for low authoritarianism, we found a correlation between attitude and attitude importance. The discussion focuses on the value-expressive function of death-related attitudes.     

分类过程中汉字的语义提取(Ⅱ)

本研究是对汉字分类过程中语义提取的进一步探索,主要研究汉字双字词的语义提取。本研究的结果表明:(1)义符的作用在双字词的语义提取中依然存在,其趋势与在单字词中的情形是一致的。(2)被试在加工双字词时所采用的是平行加工的方式。(3)在汉字的语义提取中,被试头脑中的高级信息也有重要的作用。     

海马CA_3区在长时记忆的保持中的作用

本工作将M-胆碱能受体阻断剂东莨菪碱,r-氨基丁酸及其受体阻断剂印防己毒素,经埋植的慢性导管注入家兔双侧海马CA_3区,观察上述药物对已巩固的操作式食物性条件反应的影响。发现东莨菪碱(每侧45微克/5微升)、r-氨基丁酸(每侧3毫克/5微升)均使条件反应抑制;若注r-氨基丁酸之前先加注印防己毒素,则抑制时间缩短,且剂量愈大时间更为缩短。抑制期间动物的摄食和运动功能正常,抑制后条件反应皆恢复;注生理盐水作自身对照则均无抑制效应。这表明海马CA_3区在长时记忆的保持上起着重要作用,且此种作用有胆碱能突触和GABA能突触参与。
