Group Size Effects on Risk Perception: A Test of Several Hypotheses

Yamaguchi (1998) found that people perceived a lower level of risk in a group than when they were alone, despite the fact that being in a group did not reduce the objective level of risk. Three experiments were conducted to examine several potential explanations for this effect. Experiment 1 replicated the group size effect in self-perception as well as the perception of the risk level of others. Results did not support the interdependence hypothesis and the affiliation hypothesis. Experiments 2 and 3 tested a hypothesis based on the availability heuristic. The group size effect was reduced or nullified when the target of risk judgment was associated with risk-seeking behavior or when an accident, in which many people died, was made salient.     

拓扑性质知觉的大脑半球功能不对称性研究

本文以视觉的拓扑知觉理论为指导进行大脑半球功能不对称性的研究。全文共有三个实验,考察了辨别扭扑性质差异和其它几何性质差异时大脑半球的功能不对称性．拓扑性质差异包括洞（封闭性）的差异和内外关系的差异．实验结果显示：对于右利手被试,辨别拓扑性质差异时,左半球有优势。辨别距离和朝向等几何性质差异时,右半球有优势或没有统计显著的大脑半球功能不对称性。     

卡车驾驶员视觉选择性注意研究

采用注意力测验量表,对２８０名男性卡车驾驶员的视觉选择性注意进行了测量。研究发现：事故组与安全组卡车驾驶员的完成时间、漏划数和平均每秒正确删数有很显著差异,错划数有显著差异;事故多发组与安全组卡车驾驶员的完成时间和平均每秒删数有很显著差异,错划数有显著差异;年龄对卡车驾驶员的视觉选择性注意有显著影响,随着年龄的增加,卡车驾驶员完成视觉选择性注意作业的时间增长,漏划数和错划数增多,平均每秒正确删数减少,而４０－５０岁则是卡车驾驶员视觉选择性注意速度和准确性下降的转折点。     

土三七所致肝小静脉闭塞病142例治疗的临床分析

通过对土三七引起的肝小静脉闭塞病的治疗进行总结分析,提高临床上对肝小静脉闭塞病的认识.检索2000年1月至2011年9月国内有关土三七致肝小静脉闭塞病的文献68篇、总计病例140例,本院收治的2例.对142例治疗方法进行统计分析.急性及亚急性期的内科治疗与急性及亚急性期的分流术治疗对比,无显著差异P＞0.05,慢性期的内科治疗与慢性期的分流术治疗对比,有显著差异P＜0.05.肝穿刺病理活组织检查是确诊肝小静脉闭塞病的有效方法,且可进行病理分期；肝小静脉闭塞病的急性进展期内科综合治疗有一定疗效,慢性期病例应在积极内科综合治疗的同时及早创造条件行分流术治疗.     

免费师范生教师职业认同量表的编制

鉴于免费师范生的特殊性,有必要对其教师职业认同进行科学研究。本研究在前期调研与访谈的基础上,对北京某高校284名免费师范生进行问卷测试,编制了《免费师范生教师职业认同量表》,并重新选取168名免费师范生施测,采用验证性因素分析技术对量表进行结构检验。研究结果表明：（1）免费师范生的教师职业认同感包括内在价值认同、外在价值认同、意志行为认同三个维度;（2）免费师范生教师职业认同量表具有良好的信、效度。     

Adult Attachment Ratings (AAR): An Item Response Theory Analysis

The Adult Attachment Ratings (AAR) include 3 scales for anxious, ambivalent attachment (excessive dependency, interpersonal ambivalence, and compulsive care-giving), 3 for avoidant attachment (rigid self-control, defensive separation, and emotional detachment), and 1 for secure attachment. The scales include items (ranging from 6–16 in their original form) scored by raters using a 3-point format (0 = absent, 1 = present, and 2 = strongly present) and summed to produce a total score. Item response theory (IRT) analyses were conducted with data from 414 participants recruited from psychiatric outpatient, medical, and community settings to identify the most informative items from each scale. The IRT results allowed us to shorten the scales to 5-item versions that are more precise and easier to rate because of their brevity. In general, the effective range of measurement for the scales was 0 to +2 SDs for each of the attachment constructs; that is, from average to high levels of attachment problems. Evidence for convergent and discriminant validity of the scales was investigated by comparing them with the Experiences of Close Relationships–Revised (ECR–R) scale and the Kobak Attachment Q-sort. The best consensus among self-reports on the ECR–R, informant ratings on the ECR–R, and expert judgments on the Q-sort and the AAR emerged for anxious, ambivalent attachment. Given the good psychometric characteristics of the scale for secure attachment, however, this measure alone might provide a simple alternative to more elaborate procedures for some measurement purposes. Conversion tables are provided for the 7 scales to facilitate transformation from raw scores to IRT-calibrated (theta) scores.     

三岁之前幼儿对错误信念的理解

关于幼儿开始理解错误信念的年龄,一直存在激烈的争论。目前颇具影响力的观点认为,幼儿只有在4岁左右才能理解错误信念,3岁幼儿至多只能隐性理解错误信念。支持这种观点的证据主要来自于对幼儿的错误信念的言语实验。由于这些实验结果被认为与言语测试范式相关,越来越多的实验采用非言语测试方法,结果发现3岁,甚至3岁之前幼儿就能够理解错误信念。同时,这一观点也获得了一些理论证据的支持。

Revelation,delusion or disillusion: subjective interpretation of religious and spiritual experiences in bipolar disorder

The objective of this study is to explore the interpretation of religious and spiritual experiences during mania, depression and recovery, from the perspective of bipolar clients and to inquire into their expectations of treatment in relation to these experiences. For this purpose, a qualitative pilot study is designed, which includes interviews with 10 outpatients of Altrecht, a Dutch mental health institution. The meaning of religious and spiritual experiences and the question of their authenticity proved to be an important theme for the participants. The support of spirituality for illness management was brought to the fore, as well as the temporary lack of this support during depression by some participants. Participants considered it desirable that more attention be paid to the topic during treatment, and to establish better cooperation between spiritual counsellors of the institution and other professionals. Thus, a more existential or hermeneutical approach towards religious experiences in relation to bipolar disorder would be a desirable contribution to standard treatment. The exact outlines of such an approach demand more empirical research.     

Working memory and insight in the nine-dot problem

In the present article, we examine the contribution of working memory (WM) to solution of the nine-dot problem, a classic insight problem. Prior research has generally demonstrated a limited role for WM in the solution of insight problems, which are typically assumed to be solved without conscious planning. However, MacGregor, Ormerod, and Chronicle (2001) proposed an information-processing model that solves the nine-dot problem by relying on a visual WM mechanism, which they term lookahead. In the present research, we examine whether performance on the nine-dot problem is indeed predicted by WM capacity. The results indicated that spatial WM capacity predicted the tendency to draw lines outside the configuration of dots and predicted the solution on a hint-aided version of the problem. Furthermore, within those solving the problem, higher spatial WM capacity was also related to faster solutions. The results support the information-processing model and suggest a more essential role for WM and planning in insight problem solving than has previously been acknowledged.
