肢体伤残者心理康复的试探性研究

三年来,根据接待配装假肢及康复治疗伤残病人的实际情况,我们选择了感觉、知觉和记忆三个项目,进行了测定,即:(1)伤残部位和对应部位的两点阈值测定;(2)装戴假手后提重差别阈限的测定;(3)再认能力测定。结果表明,这些测定对伤残病人的康复治疗和心理评定都有一定的参考价值。     

Approaching math increases math = me and math = pleasant

In two studies, we examined the effect of extensive practice in approaching math on implicit identification with math, implicit math attitudes, and behavior during a math test. The results from Study 1 demonstrated that women trained to approach math showed more identification with and positive implicit attitudes toward math than women trained to avoid math. Notably, this latter pattern of findings was only evident for women low in initial identification with this field. The results from Study 2 replicated these findings by showing that women who were initially low in math identification and trained to approach math showed more implicit identification with math and attempted more items on a math test than women trained to respond to math in a neutral way. The implications of these findings for current theorizing on the gender gap in women’s representation in math related careers are discussed.     

Dislocations and cracks at Vickers indentations in (0 0 0 1) GaN single crystals

Single-crystal (0 0 0 1) GaN samples have been deformed with a Vickers indenter at room temperature using loads in the range from 0.02 to 4.90 N. Dislocations and cracks at the indentations were examined by means of scanning electron microscopy, cathodoluminescence, light microscopy and transmission electron microscopy. Geometrical relations could be found between the dislocation arrangement, cracks and the orientation of the indenter. The orientation of the indenter has only a slight effect on the dislocation pattern, but the crack system is predominantly determined by the symmetry and the orientation of the indenter.

戴震论认识与情欲

本文主要探讨戴震关于认识和情欲的心理思想。在认识心理思想方面,主要从三个观点、关于感知、关于心知、关于感知与心知的关系等四个方面加以论述。在情欲心理思想方面,主要从两个观点、关于情、关于欲、关于对待情欲的主张等四个方面加以论述。     

Nameless + harmless = blameless: When seemingly irrelevant factors influence judgment of (un)ethical behavior

People often make judgments about the ethicality of others’ behaviors and then decide how harshly to punish such behaviors. When they make these judgments and decisions, sometimes the victims of the unethical behavior are identifiable, and sometimes they are not. In addition, in our uncertain world, sometimes an unethical action causes harm, and sometimes it does not. We argue that a rational assessment of ethicality should not depend on the identifiability of the victim of wrongdoing or the actual harm caused if the judge and the decision maker have the same information. Yet in five laboratory studies, we show that these factors have a systematic effect on how people judge the ethicality of the perpetrator of an unethical action. Our studies show that people judge behavior as more unethical when: (1) identifiable vs. unidentifiable victims are involved and (2) the behavior leads to a negative rather than a positive outcome. We also find that people’s willingness to punish wrongdoers is consistent with their judgments, and we offer preliminary evidence on how to reduce these biases.     

学习和记忆的神经生物学基础在无脊椎动物的研究进展

本文综述了Kandel及其同事们在海兔的研究,以示学习和记忆的神经生物学基础在无脊椎动物的研究进展。全文分四个部份:行为观察、细胞机制、分子水平研究和敏感化与经典条件化的比较。各部份又分若干段落综述。本文认为他们的工作在细胞机制方面可说是有所突破。

大鼠作业成绩与脑内亮氨酸脑啡肽含量变化的相关性研究

本工作采用穿梭式电击回避反应法和脑啡肽的放射免疫测定法,分析比较了大鼠作业成绩与脑内壳氨酸脑啡肽(Leu-enkephalin,LEK)含量的关系,在本实验条件下,观察到作业成绩不良组纹状体内LEK含量显著高于成绩优良组和对照组,并由实验证明,它们之间的差异不是由于在实验中接受电击的次数或电击总量不同造成的。这一结果提示,内源性亮氨酸脑啡肽可能参与记忆获得的调制。
