引入眼动注视点的联合-交叉负载多模态认知诊断建模

多模态数据为实现对认知结构的精准诊断及其他认知特征(如, 认知风格)的全面反馈提供了可能性。为实现对题目作答精度、作答时间(RT)和视觉注视点数(FC)的联合分析, 本文基于联合-交叉负载建模法提出3个多模态认知诊断模型。实证研究及模拟研究结果表明: (1)联合分析比分离分析更适用于多模态数据; (2)新模型可直接利用RT和FC中信息提高潜在能力或潜在属性的估计准确性; (3)新模型的参数估计返真性较好; (4)忽略交叉负载所导致的负面结果比冗余考虑交叉负载所导致的更严重。     

Recherche sur données : aspects juridiques et éthiques à travers l’expérience de l’hôpital Foch

Health data is the object of covetousness by many actors, of course by the healthcare industry, in particular the drug and medical device industry, by hospitals and research institutes, but also by all types of merchant companies which would like to derive substantial benefits from it. Faced with this phenomenon, the European Commission, within the framework of the replacement of the European Directive on health data of 1995, by the General Data Protection Regulation of 2016 (GDPR) has strengthened the protection of health data which is particularly sensitive data for everyone and, consequently, carrying out studies on health data. Researches that does not involve human beings, improperly called “Data studies”, are closely regulated by the GDPR and, for France, by the Data Protection Act, which has been amended accordingly. This article describes the steps to be taken for the implementation of data studies and what are the rights of participants/patients in the context of these researchs. Ethical vigilance would require that such research be reviewed by an ad hoc committee.     

基于过程数据的问题解决能力测量及数据分析方法

问题解决能力是指在没有明显解决方法的情况下个体从事认知加工以理解和解决问题情境的能力。对问题解决能力的测量需要借助相对更复杂、更真实、具有可交互性的问题情境来诱导问题解决行为的呈现。使用虚拟测评抓取问题解决的过程数据并分析其中所蕴含的潜在信息是当前心理计量学中测量问题解决能力的新趋势。首先, 回顾问题解决能力测量方式的发展：从纸笔测验到虚拟测评。然后, 总结对比两类过程数据的分析方法：统计建模法和数据挖掘法。最后, 从非认知因素的影响、多模态数据的利用、问题解决能力发展的测量、其他高阶思维能力的测量和问题解决能力概念及结构的界定五个方面展望未来可能的研究方向。     

Mediation analysis and categorical variables: Some further frontiers

Iacobucci (2012) provides a conceptually appealing, readily implemented measure to assess mediation for a far wider range of data type combinations than traditional OLS-based analyses permit. Here, we consider potential applications and extensions along several lines, particularly in terms of random utility models, simulation-based estimation, and potential nonlinearities, as well as some methodological and cultural impediments.     

Effects of (un)employment on young couples’ health and life satisfaction

This study investigated effects of employed and unemployed job status on health outcomes with questionnaires in 50 young couples. Analysis of variance revealed higher pessimism, higher stress levels, and lower life satisfaction in couples in which one partner was unemployed. These couples also exhibited more health risk behaviours compared to couples in which both partners were working. The dyadic analysis of data, using an actor–partner interdependence model, demonstrated strong actor and partner effects for male partner's job status. Being unemployed was significantly associated not only with male partner's life satisfaction but also with the life satisfaction of his female partner. In addition, male partner's pessimism was identified as a significant variable which mediates between male partner's job status and female partner's life satisfaction. The study highlights the relevance of the accomplishment of tasks in the domains of work and partnership during young adulthood and it emphasises the gender specific importance.     

Competence and control orientations as predictors of test anxiety in students: Longitudinal results

Abstract

The hypothesis that domain-specific self-related cognitions (self-concept of own competence and control orientations) are predictors of text anxiety in students is tested by longitudinal data. At the beginning and at the end of a school year the following variables were measured twice in a sample of 346 secondary school students (grades six to ten): (1) self-concept of own competence in mathematics, (2) three aspects of locus of control for problem-solving behavior (internality, powerful others control, and chance control), (3) generalized locus of control of reinforcement, (4) test anxiety as well as manifest anxiety. The cross-sequential developmental gradients point toward symmetries in the development of self-related cognitions and test anxiety. The results of cross-lagged correlation analyses show that the null hypothesis (no causal relations exist between the self-related cognitions and test anxiety) can be rejected for the domain-specific aspects of (a low) self-concept of own competence and locus of control (low internality and high chance control), which are confirmed as preceding test anxiety. However, longitudinal results also show that findings of cross-sectional studies tend to overestimate the relations between self-related cognitions and test anxiety in a developmental perspective.     

“I have undergone some metamorphosis!” The Impact of REds on South African Educators Affected by the Hiv/Aids Pandemic. A Pilot Study

The study investigated the efficacy of Resilient Educators (REds), a group intervention program, designed to empower educators affected by the HIV/Aids pandemic and in research in progress. Fifteen participants (three male; twelve female) from various primary schools in two different South African communities were involved. Participant ages ranged from early thirties to mid-fifties. A pre-test, post-test design was conducted. Visual data were collected in the form of symbolic drawings: participants drew symbols of their perception of the pandemic and explained the meaning of their chosen symbols either in writing or verbally. A qualitative comparison of these visual data suggested transformed perception and concomitant teacher empowerment. Prior to participation in REds, participants projected vulnerability. Following their participation, participant projections suggested self-empowerment and community mindedness. Participants perceived themselves capable of coping with the challenges of the pandemic.     

ROY SCHAFER'S CONTRIBUTIONS TO PSYCHOLOGICAL TESTING: FROM CLINICAL SENSIBILITY TO THE ANALYTIC ATTITUDE

The author reviews Schafer's contributions to psychological testing, emphasizing his development of the test battery, his significant contributions to psychoanalytically oriented Rorschach interpretation, and his understanding of the complex interpersonal dynamics involved in psychological test interpretation. The author also discusses his use of Schafer's writing in his own teaching and academic work, noting that Schafer's contributions have not only provided innovative methods for examining test data, but have also promoted a respectful, humanistic, and individualized approach to the patient in testing and treatment. The author asserts that Schafer's later seminal contributions to psychoanalysis had their origins in his early career as a psychologist applying psychoanalytic ideas to testing.
