消费决策中羊群行为的启发式加工及产生根源

消费决策中的羊群行为是消费市场上的一种典型现象.它是指在不确定情境中,消费者模仿他人进行消费决策的行为.本研究通过两个实验逐步揭示了消费决策中羊群行为的产生根源.实验1研究表明,消费决策中的羊群行为是消费者利用一致性启发式或能力启发式加工信息的结果.实验2通过内隐联想测验进一步研究表明,个体使用两种启发式的原因在于消费者对大众和专家的刻板印象:他们总是认为大众和专家的决策是正确的.     

表象测量方法述评

表象测量在训练领域广泛应用,也是训练成败的关键环节.表象测量方法可分为口头报告纸笔法、实验操作法,以及神经科学技术共三种方法.其中纸笔报告法以量表测量为主,包括Betts量表、视觉表象清晰度量表及其修订版和运动表象清晰度量表及其修订版;实验操作法以心理旋转为基本范式;神经科学技术主要以经颅磁刺激和功能磁共振成像为主,测量多种表象过程中不同脑区兴奋性.三者各有优劣,均有待提高和改进.     

社会网络分析在心理研究中的应用

个体不是孤立存在的, 其心理与行为的变化常依赖于与他人存在的关系。社会网络分析正是考虑到了这种依赖性, 发展出相应的处理关系变量的方法。在介绍社会网络理论的中心思想、社会网络分析的基本概念、数据表示方法和研究方法以及在个体水平和关系水平上的静态统计模型后, 使用UCINET软件展现了处理关系数据的基本步骤, 并简述社会网络分析在人格心理学、发展与教育心理学和管理心理学中的应用。     

Tigers are something else: A case for family play

This paper is an attempt to bridge the two worlds of family therapy and filial play therapy, introducing the complementary idea of play in therapy. Family play therapy challenges the idea that play is only useful in the treatment of children. Clinical examples are given and uses of play are discussed, including evaluation, play as a therapeutic tool, and the development of themes. The authors believe that therapists who are willing to be playful offer their clients a new world of therapeutic experiences.     

THE EFFECTS OF TARGETING IMPROVEMENTS IN URINE GLUCOSE ON METABOLIC CONTROL IN CHILDREN WITH INSULIN DEPENDENT DIABETES

A treatment program designed to increase the percentage of negative urine tests was implemented using a multiple-baseline across groups design in a sample of 19 families of children with insulin dependent diabetes. The treatment involved instructions in insulin adjustment, decrease in intake of simple sugars and saturated fats, and increase in exercise, along with teaching the parents to support improvements in children's self-regulatory behaviors using a point economy and praise. New proocedures designed to measure and reinforce adherence to the urine testing regimen were developed. Results showed significant increases in percentage of negative urines consistent with implementation of treatment across the three treatment groups, which were maintained over the follow-up period. Metabolic measures of control, including glycosylated hemoglobin and serum glucose did not show improvements even though the relationship between the percentage of negative urine tests and glycosylated hemoglobin was very high during treatment.     

Observing groups as seen from both sides of the looking glass

Conclusion This paper attempts to make a contribution to an area of the literature on group therapy about which very little has been published—the effects of the therapy group upon the observing group and the dynamics of the observing group as an entity in itself. Although work on which this paper is based took place in training institutions where education is the primary function, it is important to emphasize that education and personal change are interrelated. Psychotherapeutic activity takes place spontaneously with the observers and needs to be constructively utilized. This wealth of process and reaction is an untapped training opportunity for the observing group. The challenge of method, personal reactions, and group process responses are all opportunities for its members to both learn more as therapists and mature as individuals. At this juncture, we are trying to establish ways of     

A faithful embedding of parallel computations in star-finite models

The purpose of this paper is to show that there exist star-finite tree-structured sets in which the computations of parallel programs can be faithfully embedded, and that the theory of star-finite sets and relations therefore provides a new tool for the analysis of non-deterministic computations.This research was carried out while the author held a Postdoctoral Fellowship from the Natural Sciences and Engineering Research Council of Canada.

Observation procedure, observer gender, and behavior valence as determinants of sampling error in a behavior assessment analogue

Several factors thought to influence the representativeness of behavioral assessment data were examined in an analogue study using a multifactorial design. Systematic and unsystematic methods of observing group behavior were investigated using 18 male and 18 female observers. Additionally, valence properties of the observed behaviors were inspected. Observers' assessments of a videotape were compared to a criterion code that defined the population of behaviors. Results indicated that systematic observation procedures were more accurate than unsystematic procedures, though this factor interacted with gender of observer and valence of behavior. Additionally, males tended to sample more representatively than females. A third finding indicated that the negatively valenced behavior was overestimated, whereas the neutral and positively valenced behaviors were accurately assessed.     

中学生学习主观幸福感及其影响因素的初步研究

以910名从初一到高三的中学生为被试,采用自编的《中学生学习主观幸福感量表》进行研究。结果表明:(1)中学生学习主观幸福感普遍偏低,且存在学校类型、年级的差异,非重点学校学生学习主观幸福感更低;高二、初二学生学习主观幸福感最低。(2)影响中学生学习主观幸福感的直接因素是学习体验和现有学习成绩,其中,前者作用更大。(3)影响中学生学习主观幸福感的间接因素是社会压力和希望学习成绩,它们通过学习体验或现有学习成绩间接作用于学习主观幸福感。
