Attending to the distractor and old/new discriminations in negative priming

When participants ignore an irrelevant distractor they typically show impaired responding to that item if it becomes the relevant stimulus on a subsequent trial. In Experiment 1 (N = 64), a masked white colour name was presented briefly before a Stroop display. Negative priming in colour naming occurred when the colour of the lettering for the Stroop stimulus matched the colour name displayed in the first display, consistent with the proposal of temporal discrimination theory that negative priming arises because a recurrence of an unattended stimulus cannot readily be classified as old or new. Experiment 2 (N = 32) replicated negative priming in the interleaved-word display where participants had to name the red word from a pair of red and green words. In Experiment 3 (N = 32) and Experiment 4 (N = 28) the participants were required to attend to but not respond to the words in the prime display and name one of two interleaved words in the probe display. Negative priming was observed in this arrangement, consistent with the episodic retrieval theory of negative priming. The temporal discrimination model may need to be extended to situations in which the attended stimuli have different responses attached to them.     

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.     

Can chimpanzees learn a phonemic language?

Two groups of investigators have recently reported some success in teaching language to chimpanzees. This finding has been generally attributed to the choice of a favorable communication modality. However, the fact that the languages employed were not phonemic also seems critical. It is doubtful whether chimpanzees could learn a phonemic language.This research was supported in part by PHS Grants No. GM01789 and GM16735 to The Rockefeller University.
