自我概念对主观幸福感预测的内隐社会认知研究

从内隐社会认知的观点出发研究自我概念和主观幸福感的结构,并在此基础上探讨自我概念对主观幸福感的影响,得到以下结论:在中国大学生样本中(1)自我概念是双重的,存在外显自我和内隐自我两种成分;(2)主观幸福感结构是双重的,存在外显幸福感和内隐幸福感两种成分;(3)自我概念对主观幸福感的预测模型为:外显自我预测外显幸福感,内隐自我预测内隐幸福感。     

事件相关电位(ERPs)反映汉字与其心理模板的失匹配

以10名年龄为19—24岁的男性大学生为被试进行了ERP实验。当被试对特定汉字的心理模板与实际呈现的汉字不匹配时,记录到一峰潜伏期在400ms左右的负走向波——N400。在形、义因素得到控制的条件下,汉字刺激和其心理模板间音因素的匹配与否影响到N400的左右不对称程度。N400和P300部分重叠,受到非语言因素如刺激字比例和判断任务的调制。     

双眼立体视觉的信息加工 Ⅱ.空间滤波对双眼立体感的影响

本工作的目的是希望了解立体感形成时双眼图象空间频谱的融合规律。我们利用不同质地的两套随机点立体图对,经过不同空间频带(低通、高通、带通)的光学滤波处理,然后将滤波后的图象作各种左右眼搭配观察。得到: 1.同样滤波的立体图对均能形成立体感; 2.不同质地的立体图对,空间频带搭配相同,但观察结果并不完全相同。 3.目前我们尚不能用立体图对的两个图像的空间频带是否重叠来了解两眼融合的规律。     

激光用光导纤维导入大鼠皮层额叶和尾状核对纹状体的单胺类和氨基酸类神经介质含量的影响

迄今为止,激光在脑研究和临床应用上,主要是利用高功率激光做为手术刀、激光武器及其防护等方面。即使在这方面、由于激光辐照的穿透力很小,限制了它的应用。对于它们的基础研究多见为皮肤和血液肝脏细胞和神经细胞生理生化指标的改     

Sex stereotypes and implicit personality theory. I. A personality description approach to the assessment of sex stereotypes

It was proposed that sex stereotypes be phrased in terms of the person perception construct, “implicit personality theory,” as the structured sets of inferential relations that link personal attributes to the social categories female and male. The utility of this formulation was assessed by having 31 college students use a set of 66 personality traits to describe other people. A measure of trait co-occurrence was derived from these data and was used as input to Kruskal's multidimensional scaling program. A two-dimensional configuration was interpreted in terms of two orthogonal properties, Social Desirability and Potency. An Indirect Female-Male property (based on the proportion of times each trait was used to describe a male) was strongly related to the configuration and was closely aligned with the Potency vector. Thus, stereotypes of females and males were associated with the Potency dimension of person perception, with females seen as “soft” and males as “hard.” The directly rated sex property Male-Female was also located near the Potency vector, but was not strongly related to the configuration. This lack of fit may have been due to social desirability responding. The results support the utility of formulating sex stereotypes in terms of implicit personality theory and suggest the need to distinguish direct and indirect assessments of stereotypes.     

Individual differences in preschool object play: The influences of anxiety proneness and peer affiliation

Individual differences in anxiety and peer affiliation were investigated as factors influencing variability of object play among preschoolers. Eighteen three-year-olds were divided into high- and low-anxious groups on the bases of separation anxiety and general anxiety scales. Their mature and immature object play, their peer affiliation, and their peer-watching behaviors were observed in preschools. Low-anxious children played more, showed more mature play, and watched peers less when they were alone; high-anxious children showed no play increases but watched peers more when alone. Separation anxiety scores predicted preschool differences more sensitively than general anxiety scores. It was theorized that separation anxiety related mechanisms hinder children's ability to fully profit from preschool experiences.     

Clothing: Communication, Compliance, and Choice

This study looks at some effects of five different styles of women's clothing: Formal Skirt, Formal Pants, Casual Skirt, Casual Pants, and Jeans. There were no significant differences in compliance to a request to fill out a questionnaire made by experimenters dressed in the five clothing styles, although experimenter age and sex effects were found. Ratings of photographs of the five dress styles indicate that a model was viewed by both male and female subjects as most happy, successful, feminine, interesting, attractive, intelligent, and wanted as a friend when wearing a Formal Skirt outfit and as least so when wearing Jeans. She was also seen as more active when wearing pants as compared with a skirt. Subjects' reasons for choosing what clothing to wear did not indicate that how one will appear to others is the major factor in clothing selection. It appears that clothing does communicate something about the wearer but may influence behavior toward her primarily in the absence of other information about her status.     

Gender differences in coping and daily stress in conduct-disordered and non-conduct-disordered adolescents

Research shows that conduct disorder (CD) manifests differently in boys and girls, yet little is known about specific characteristics of girls with CD. This study examined gender differences in stress and coping in both CD (n = 69) and non-conduct-disordered (NCD) adolescents (n = 64). Results indicated similar patterns of gender differences in stress and coping, although CD adolescents reported a higher frequency of stress and maladaptive coping strategies than NCDs. Girls reported more daily stress and greater use of coping associated with both social relationships and emotional venting. A significant interaction effect distinguished girls with CD from other groups by their higher level of daily stress, more frequent use of self-injurious behavior and emotion-focused coping, and deficits in active coping.     

企业新产品开发决策的不确定性和决策策略模拟实验研究

本文以企业新产品开发为决策内容,根据决策策略的规定性理论框架和先前调查所得决策案例,设计四种决策情景来代表四种不确定状态,通过５６名来自５个工厂的管理人员的现场模拟实验,着重研究这类决策的不确定性和决策策略之间关系。结果发现,在新产品开发的决策中,决策策略随不确定状态而改变;决策情景的不确定程度和决策策略没有严格的—一对应关系;在四类不确定决策情景下,都有管理人员采用混合型策略。这一发现同混合扫瞄策略观点和垃圾罐模型的思想相一致。并且,随着决策情景的不确定程度加大,决策时间逐渐延长。最后我们提出了应继续研究的课题。     

THE USE OF GOAL SETTING AND CONTINGENCY CONTRACTING FOR IMPROVING CHILDREN'S HOMEWORK PERFORMANCE

We examined the effects of goal setting and contingency contracting on children's homework performance. Subjects were 4 parent—child dyads in which the child exhibited substantial homework problems. Using a combination of multiple baseline and reversal (ABAB) designs, goal setting and contingency contracting produced significant improvements in children's homework accuracy. Two of the 4 subjects showed substantial improvements in on-task behavior. Consumer satisfaction with the procedures was supported by parent ratings conducted posttreatment.
