International Organisations in Psychology: The International Council of Psychologists

Cet article décrit le développement de ľassociation "International Council of Psychologists". II donne des détails sur sa contribution à Finternationalisation de la psychologic
This paper looks at the International Council of Psychologists in an international perspective. Its history is briefly traced and its contributions to the "internationalisation of psychology" are discussed. The point is made that today our interest in international organisations -is guided by the extent to which this aim is reached.     

Using Response Times to Model Not-Reached Items due to Time Limits

Missing values at the end of a test typically are the result of test takers running out of time and can as such be understood by studying test takers’ working speed. As testing moves to computer-based assessment, response times become available allowing to simulatenously model speed and ability. Integrating research on response time modeling with research on modeling missing responses, we propose using response times to model missing values due to time limits. We identify similarities between approaches used to account for not-reached items (Rose et al. in ETS Res Rep Ser 2010:i–53, 2010) and the speed-accuracy (SA) model for joint modeling of effective speed and effective ability as proposed by van der Linden (Psychometrika 72(3):287–308, 2007). In a simulation, we show (a) that the SA model can recover parameters in the presence of missing values due to time limits and (b) that the response time model, using item-level timing information rather than a count of not-reached items, results in person parameter estimates that differ from missing data IRT models applied to not-reached items. We propose using the SA model to model the missing data process and to use both, ability and speed, to describe the performance of test takers. We illustrate the application of the model in an empirical analysis.

     

Research on Vocational Behavior: The Singapore Perspective

This article traces the development of vocational psychology in the Republic of Singapore from 1985 to 1997. It reviews both published and unpublished research studies on vocational psychology, including studies of career development, interests, sex-stereotyping in career choice, work values, and job satisfaction. Based on empirical data, the article examines the influences of home and school on the career development of adolescents and reviews experimental studies on various career guidance practices. The article concludes with suggestions for the future development of vocational psychology in Singapore.     

Child Compliance and Congruity between Verbal and Nonverbal Maternal Communication — A Methodological Note

This paper is a report of a study of congruity between verbal and nonverbal maternal communication with sons during two 30-minute sessions. The instructions to the mothers varied for the two sessions by increasing the time the mother was asked to spend on a brain teaser game and by decreasing the number of play materials available for the sons in the second session. The two sessions were videotaped through a one-way mirror and rated independently for maternal verbal and nonverbal communicaiton and child compliance. Mothers differed for the two sessions in their communication with their sons. The study demonstrated that maternal nonverbal communication, as well as verbal communication, can be reliably measured through use of videotape recording.     

Maximum likelihood solution to factor analysis when some factors are completely specified

In the factor-analytic model, let some of the factors be known (i.e., the factor loadings are given in advance; they maye.g. be obtained from some previous analyses). However, their covariance matrix may, or may not, be known. The remaining factors (if any) are assumed to be uncorrelated among themselves and to the first set. For this model, the maximum likelihood equations are obtained and an iterative method for the solution is proposed.The work was done while the author was at Deutsches Rechenzentrum, Darmstadt, Germany.
