Source reliability and the conjunction fallacy

Information generally comes from less than fully reliable sources. Rationality, it seems, requires that one take source reliability into account when reasoning on the basis of such information. Recently, Bovens and Hartmann (2003) proposed an account of the conjunction fallacy based on this idea. They show that, when statements in conjunction fallacy scenarios are perceived as coming from such sources, probability theory prescribes that the "fallacy" be committed in certain situations. Here, the empirical validity of their model was assessed. The model predicts that statements added to standard conjunction problems will change the incidence of the fallacy. It also predicts that statements from reliable sources should yield an increase in fallacy rates (relative to unreliable sources). Neither the former (Experiment 1) nor the latter prediction (Experiment 3) was confirmed, although Experiment 2 showed that people can derive source reliability estimates from the likelihood of statements in a manner consistent with the tested model. In line with the experimental results, model fits and sensitivity analyses also provided very little evidence in favor of the model. This suggests that Bovens and Hartmann's present model fails to explain fully people's judgements in standard conjunction fallacy tasks.     

初中生情感能力问卷的初步编制

目的:编制初中生情感能力问卷,检验其信效度。方法:在文献研究的基础上,构建初中生情感能力的理论维度,编写问卷题目。对316名初中生进行预测,形成初步问卷,再对864名初中生进行测量。使用SPSS17.0和Lisrel8.7软件对问卷进行探索性因素分析和验证性因素分析。结果:初中生情感能力结构分为情感识别能力、情感体验能力、情感评价能力、情感管理能力四个维度,由15道题目组成。验证性因素分析的GFI,NNFI,AGFI,CFI,IFI均在0.9以上,模型拟合较好。结论:初中生情感能力问卷具有较好的信度和效度,可以成为评定初中生的情感能力素质的测评工具。     

心理健康素质测评系统·中国成年人一般自我概念量表的编制

旨在编制适合中国成年人的一般自我概念测量工具。通过理论分析,建构了一般自我概念的四个维度,包括积极性、清晰性、悦纳性和调节性,并据此编制了中国成年人一般自我概念量表。分别选取北京地区450名和400名大学生进行预试和正式测试：验证性因素分析表明,建构的一般自我概念四维测量模型结构合理,拟合良好;项目及信效度分析表明,量表各项目区分度良好,信、效度符合心理测量学要求。因此,该量表可作为成年人一般自我概念和自我心理健康素质的测量工具。     

心理健康素质测评系统·中国成年人人际健康素质量表的编制

在文献分析和专家评定的基础之上,构建了人际健康素质的基本结构,并编制了初始的中国成年人人际健康素质问卷。然后通过项目区分度分析和验证性因素分析对初始问卷进行了修订,最终形成了包括合群性、亲仁性、利他性、共情性和友善性5个维度的正式量表。结果表明,人际健康素质量表具有较高的内部一致性信度、重测信度和分半信度以及较好的内容效度、结构效度、校标关联效度和会聚效度。结论：人际健康素质量表具有较好的心理测量学特征,可以作为中国成年人人际健康素质的心理测量工具。     

初中生友谊认知的类型特点

本研究在已有理论及开放式问卷基础上首先确定友谊认知的初步结构,采用探索性因素分析调整结构并筛选题目,最终确定友谊认知问卷的4个维度。验证性因素分析表明,自编的友谊认知问卷具有较好的结构效度,其他各项信效度指标也均达到心理测量学的要求。另外,聚类分析表明可以把初中生的友谊认知划分为重情感-重兴趣、重情感-轻兴趣和情感淡漠-轻兴趣3种类型。

Millon Clinical Multiaxial Inventory (MCMI) scores with a collegiate sample: Long-term stability and self-other agreement

This study examined (a) the stability of the personality and symptom scales of the Millon Clinical Multiaxial Inventory (MCMI) for a sample of university undergraduates and (b) the correspondence between MCMI scores from self-report versus scores obtained from knowledgeable others who responded by describing the subject rather than themselves. The MCMI was administered to subjects during their freshman year and then again during their senior year. As in clinical populations, stability estimates in this collegiate sample were greater for the basic personality scales than for the symptom scales. Comparison of the results with those from previous studies further showed that the stability coefficients for the collegiate sample were somewhat lower overall than those from treatment follow-up studies with clinical populations. The results also showed that reasonable agreement between self- and others' ratings was obtained on most MCMI scales. The greatest agreement was found for scales that reflect more observable behaviors and relate to an introversion-extroversion dimension, whereas the least agreement was found for scales related to a psychoticism dimension. Lower levels of agreement were also found for scales having a lower mean proportion of items endorsed.This study was sponsored in part by PHS Grant R01 MH31750-01-6, by PHS Grant 5R01 AA06754-01-03, and by funds from the University of Connecticut Research Foundation and Computer Center.     

Reliability and validity of a cost-efficient sociometric measure

Sociometric measures have been used frequently to measure social status; however, reliable sociograms for young children usually involve time-consuming administrations. A group-administered, peer-rating sociogram, the Sociometric Peer-Rating Scale (SPRS), was devised and given to 217 first and second graders. Concomitantly, teacher nominations of children most liked, aggressive, or withdrawn and behavioral observations of the high- and low-SPRS children were obtained. After 7 months, the SPRS was readministered. On a separate population of eight kindergarten children, this sociogram and a similar, individually administered sociogram were given. Normative data, test-retest reliability, and split-half reliability were reported. The test-retest reliability was comparable to the reported reliability of other peer-rating sociograms, and the SPRS correlated significantly with teacher ratings of aggressiveness and likability and with the individually administered sociogram. The number of positive interactions was significantly different for high-versus low-SPRS children. The usefulness of the SPRS as a measure of social competence was discussed.This research was submitted by the author in partial fulfillment of the requirements of a master's degree at the Florida State University.I would like to thank the Master's committee, Wallace Kennedy, William Pelham, and Joseph Torgesen, and the participating schools, Developmental Research School of Florida State University and Woodville Elementary School of the Leon County School District, for their assistance in this study.
