Social dilemmas as strong versus weak situations: Social value orientations and tacit coordination under resource size uncertainty

This study investigates how environmental uncertainty in resource dilemmas influences the decisions of participants differing in social value orientations. We argue that under resource size certainty people anchor their decisions on tacit coordination rules such as the equal division rule, whereas under resource size uncertainty people rely more on their own social value orientations to determine their choice behavior. The results corroborate our line of reasoning. When the size of the resource was certain, proselfs as well as prosocials anchored their decisions on the equal division rule. Under resource size uncertainty, the equal division rule appeared to lose its coordinating potential, inducing proselfs to harvest more than prosocials.     

Children of Lesbian and Gay Parents

ABSTRACT— Does parental sexual orientation affect child development, and if so, how? Studies using convenience samples, studies using samples drawn from known populations, and studies based on samples that are representative of larger populations all converge on similar conclusions. More than two decades of research has failed to reveal important differences in the adjustment or development of children or adolescents reared by same-sex couples compared to those reared by other-sex couples. Results of the research suggest that qualities of family relationships are more tightly linked with child outcomes than is parental sexual orientation.     

创业导向与企业绩效：胜任力和资源的影响

企业家和高管人员的胜任力是管理心理学重点研究的领域之一。以往研究表明,创业导向和企业家胜任力是中小企业获得持续竞争优势的关键所在,而企业资源则是构成企业竞争优势的来源。为了进一步推动创业导向、企业家胜任力、资源与绩效之间关系的研究,我们对137家中小餐饮企业进行问卷测量。研究结果显示:创业导向通过企业家胜任力对企业绩效产生促进作用;企业资源在创业导向和企业绩效间起到正向调节作用。     

大学生的文化取向、自我概念对主观幸福感的影响

对成、渝两地228名大学生进行了测试,探讨大学生不同的文化取向和自我概念对其主观幸福感的影响。结果表明:大学生的文化取向以水平集体主义取向为主;年级、性别和家庭经济收入状况对幸福感均不产生影响;自我概念的各因子除与情感平衡呈显著负相关外,其他均为显著正相关;垂直个人主义文化与负性情感呈显著负相关,与情感平衡呈显著正相关;心理自我、生理自我和水平集体主义对生活满意度指数A和B有显著的预测效应;社会自我、自我批评和水平个人主义对正性情感有显著的预测效应,心理自我、自我批评和垂直个人主义对负性情感有显著的预测效应,心理自我、垂直和水平的个人主义对情感平衡有显著的预测效应。

Orientation and lever responding in auditory discriminations in squirrel monkeys.

Head orientation during auditory discriminations was studies in squirrel monkeys using a two-lever trial-by-trial procedure. Animals were studied using auditory discriminations based on the position of the sound and on the spectral content differences between a pure tone and a noise. After the percentage of correct responses reached asymptote, head orientation was measured using videotape recordings. Orientation occurred on virtually every trial and was under the control of the position of the sound under all conditions. Lever responding was controlled by the same parameters of the sound under some conditions, and by different parameters in others. Orientation and lever responding were correlated (a level response could be predicted from the direction of orientation) when both responses were under the control of the same parameters of the sound. The two responses were uncorrelated when they were controlled by different parameters of the sound. Orientation and lever responding were not functionally related.     

An evaluation of reality orientation therapy

An evaluation was made of reality orientation therapy utilizing 14 male patients with dementias of various types. The therapy is designed to improve memory and reduce confusion in elderly and demented individuals. Utilizing a group comparison with crossover design, it was found that the patients improved significantly over sessions on orientation items actually taught during those sessions. However, no significant improvement was found on a series of generalization items consisting of orientation-related questions that were not asked during sessions. Furthermore, there was no generalization to ward activities. It was noted that individual responses to the treatment were quite varied, and so three cases reflecting highly different responses are presented.Indebtedness is expressed to the Veterans Administration for support of this research.     

EFFECTS OF COOPERATIVE LEARNING GROUPS DURING SOCIAL STUDIES FOR STUDENTS WITH AUTISM AND FOURTH-GRADE PEERS

We investigated the use of cooperative learning groups as an instructional strategy for integrating 2 students with autism into a fourth-grade social studies class. Baseline consisted of 40 min of teacher-led sessions including lecture, questions and discussion with students, and the use of maps. The intervention condition consisted of 10 min of teacher introduction of new material, followed by cooperative learning groups that included tutoring on key words and facts, a team activity, and a whole class wrap-up and review. An ABAB design showed increases for target students and peers for the number of items gained on weekly pretests and posttests, the percentage of academic engagement during sessions, and durations of student interaction during the intervention.     

The Reaction of the Youth in Israel to the Assassination of Prime Minister Yitzhak Rabin

The assassination of Israeli Prime Minister Yitzhak Rabin by a political assassin caused shock, disbelief, and deep grief to the Israeli people. Particularly prominent was the reaction of the youth, who gathered in large crowds, at the site of the murder and in other places, and engaged in various mourning behaviors of a ritual nature. This drew the attention of the media in Israel and around the world. A study of approximately 700 teenagers conducted after the assassination examined their emotional reactions, participation in ritualistic mourning activities, and assessments of the reasons for feeling shocked. In all areas, differences were found as a function of gender, and attitudes toward Rabin's peace policy. An attempt was made to explain the youth's behavior in terms of the formation of groups and group identity.     

线方向判断测验在神经内,外科临床的应用与评价

对200名正常人及168例脑损害病人分别进行了线方向判断测验的测查。发现在对照组中,年龄、性别、文化水平对测验成绩均有一定的影响,尤以文化水平的影响最为显著。各病种组与对照组比较,发现脑梗塞组与脑肿瘤组成绩比外伤组和血管畸形组为差。同时还发现所有病种组右脑损害患者分数均低于左脑损害患者。
