Constructing the exact significance level for a person fit statistic

This paper uses an extension of the network algorithm originally introduced by Mehta and Patel to construct exact tail probabilities for testing the general hypothesis that item responses are distributed according to the Rasch model. By assuming that item difficulties are known, the algorithm is applicable to the statistical tests either given the maximum likelihood ability estimate or conditioned on the total score. A simulation study indicates that the network algorithm is an efficient tool for computing the significance level of a person fit statistic based on test lengths of 30 items or less.     

An automated test development of parallel tests from a seed test

Binary programming models are presented to generate parallel tests from an itembank. The parallel tests are created to match item for item an existing seed test and match user supplied taxonomic specifications. The taxonomic specifications may be either obtained from the seed test or from some other user requirement. An algorithm is presented along with computational results to indicate the overall efficiency of the process. Empirical findings based on an itembank for the Arithmetic Reasoning section of the Armed Services Vocational Aptitude Battery are given.The Office of Naval Research, Program in Cognitive Science, N00014-87-C-0696 partially supported the work of Douglas H.

个人化设计在临床研究中的应用——从个体角度研究个体差异

本文从有关研究证据的基础上,介绍了个人化设计的理论基础和实验设计,并在此基础上讨论了个人化设计在临床研究领域中的应用价值,总结出一种适合临床病人使用的研究程序。个人化设计允许对个体的个人价值进行分析,并能同时研究不同刺激信息的作用,在个体水平上分析个体差异。通过简化了的实验程序,个人化设计为解决临床研究中的问题提供了一种新的思维方式。文中还对相关研究法的局限进行了讨论。     

内侧前额皮层-伏隔核环路在决策冲动中的作用：基于动物模型的研究

注意缺陷多动障碍(attentiondeficit/hyperactivitydisorder,ADHD)行为控制不足与决策冲动密切相关,后者受内侧前额皮层(medial prefrontal cortex, mPFC)与伏隔核(nucleus accumbens, NAc)调节。为调查ADHD决策冲动与m PFC-NAc间功能耦合的关系,研究采用ADHD模型SHR (spontaneously hypertensive rat, SHR)大鼠,结合延迟折扣任务和在体电生理,研究发现,与对照Wistar (WIS)大鼠相比, SHR大鼠对延迟大奖赏的选择百分比降低; WIS大鼠m PFC-NAc的Theta频段相干值表现为延迟选择时显著大于立即选择时、首次选择时大于连续选择时、转换试次时大于连续试次时,而SHR大鼠在上述条件均低于WIS大鼠。回归分析发现m PFC-NAc的相干差值与延迟大奖赏选择率显著正相关。结果表明m PFC-NAc间功能联系减弱是ADHD决策冲动缺陷的重要环路基础,该缺陷与其深度信息加工以及策略转换能力受损有关,扩展了ADHD决策冲动的认知和神经机制的认识。     

“What matters to us”: The portrait values questionnaire to measure couple values

No previous studies have analyzed values as qualities of relational microsystems, such as the romantic couple. Based on Schwartz's Theory of Human Values, this study examines the psychometric properties of the Portrait Couple Values Questionnaire (PCVQ). It measures four couple value dimensions: conservation, openness to change, self-enhancement, and self-transcendence. Five hundred and forty-six Italian respondents (54.1% women), aged 41.52 years (SD = 7.19; range 23–63) and having a couple relationship, have filled in an anonymous online questionnaire. The results show the good psychometric properties of the PCVQ. The Confirmatory Factor Analysis Magnifying Glass Strategy shows good indexes of fit for each value dimension, except for the Root Mean Square Error of Approximation (RMSEA) for openness to change, thus confirming that the PCVQ measures the four values with satisfactory internal consistency. The Multidimensional Scaling results, by showing a Stress-1 index of 0.07, confirm the circular structure of values because the four value dimensions are in the position predicted by Schwartz's model. Participants' personal and couple values are highly but not perfectly correlated, suggesting that couple values are a related but distinct construct compared to personal values. This study's contribution lies in introducing an innovative construct into the literature on values and couples, proposing a scale to assess it.     

SCIENCE AND GOD THE CREATOR

Abstract. Variable judgments, both negative and positive, have been made by scientists (mainly physicists and astronomers) on the theological implications of their Findings. It is urged that science and theology are most appropriately related through a critical realist approach. On this basis some implications for our conceptions of God and our scientific perspectives on the created world are explored with respect to both divine Being and divine Becoming. A positive assessment of nature as created concludes the article.     

Positive and negative self-related goals and subjective well-being: A prospective study

To examine whether having self-related personal goals, or rather whether positive or negative appraisal of them, is associated with subjective well-being, 311 students were asked to complete the Personal Project Analysis (PPA) and revised Beck Depression Inventory, first at the beginning of their studies, and then 2 years later. After 3 years they were asked about the use of mental health services. Two groups of students were identified: (1) those with positive self-projects and (2) those with negative self-projects. The results showed that both positive and negative self-related projects showed stability across a 2-year period, but only negative ones were prospectively predicted by earlier depressive symptomatology. Although neither positive nor negative projects predicted depressive symptomatology, both predicted the use of mental health services.     

An Ecologically Differentiated, Multifactor Model of Adolescent Network Orientation

The paper presents a test of an ecologically differentiated model of social network orientation for adolescents that distinguished between different social network reference groups (family, peers, and nonfamily adults). The model was tested in two consecutive studies. Study 1 describes initial model development (N = 120). Study 2 presents a confirmatory factor analysis with a second sample (N = 430) to replicate the factor structure developed in Study 1. Results supported a three-factor model of network orientation that differentiated between network reference groups. Analyses of concurrent and predictive validity indicated that orientation to network reference groups was differentially related to the perceived quality and frequency of support from members of respective social network groups. Group differences (gender, race) regarding network orientation to different network reference groups were consistent with studies of other social network processes. Implications for the study of the network orientation and the study of social networks more generally are discussed.     

Personal and community sustainability

Many community members reduce their community involvements as they more through midlife. This may be true for community psychologists as well. Yet research evidence suggests that-intellectually, at least-we can function at or near peak levels through our 80s and 90s. How then might we best sustain ourselves and our work through our entire lives? Answers may lie in full exercise of all capacities, in strong support networks, and in actions that meet one's deeper needs, “the needs of the soul”. These same principles may sustain community life as well, for some key principles of personal and community sustainability may be similar. Applications of these ideas to communities and to community psychology are discussed.
