This study examined contextual and personal factors related to the use of cognitive strategies by undergraduates. Specifically, students' goal orientations (intrinsic or extrinsic) and perceptions of the classroom environment (i.e., task or performance structured) were evaluated as predictors of student use of deep or surface level cognitive…

The impetus for our study was the contention of both Lynn [Lynn, R. (1991) "Race differences in intelligence: A global perspective." "Mankind Quarterly," 31, 255-296] and Rushton [Rushton, J. P. (1995). "Race, evolution and behavior: A life history perspective." New Brunswick, NJ: "Transaction"; Rushton, J.…

To determine whether the visuospatial n-back working memory task is a reliable and valid measure of cognitive processes believed to underlie intelligence, this study compared the reaction times and accuracy of performance of 70 participants, with performance on the Multidimensional Aptitude Battery (MAB). Testing was conducted over two sessions…

Confirmatory factor analysis of Australian adaptations of combined Wechsler Adult Intelligence Scale-Revised (WAIS-R) and Wechsler Memory Scale-Revised (WMS-R) scores was conducted in a sample of 277 participants undergoing investigation for neurological disorders. The best-fitting model was a six-factor model representing the latent abilities of…

The present paper reports secular trends in the mean scores of a language, mathematics, and a Raven-like test together with a combined general ability (GA) score among Norwegian (male) conscripts tested from the mid 1950s to 2002 (birth cohorts approximately equal to 1935-1984). Secular gains in standing height (indicating improved nutrition and…

Twenty-five pediatricians responded to a confidential survey about their opinions on the relationship between otitis media and children's speech-language-hearing status. Results found that pediatricians did not necessarily agree that otitis media has an impact on speech-language-hearing development. Pediatricians reported that an early otitis…

We examined leisure behaviours and the relationships between leisure and a variety of problem behaviours in a sample of 1422 Hungarian adolescents (age range: 14-19). Findings from multivariate analyses suggest that some aspects of adolescent leisure, such as family or conventional activities, act as protective factors against problem behaviours,…

The study tested several propositions about an important construct in Bowen's (Family Therapy in Clinical Practice, Aronson, New York, 1978; Family Evaluation, Norton, New York, 1988) theory of differentiation, using an Israeli sample of adolescents to examine relationships between differentiation of self, family differentiation, test anxiety,…

Functional magnetic resonance imaging (fMRI) and event-related potential (ERP) experiments were conducted in the same group of subjects and with an identical task paradigm to investigate a possible relationship between hemodynamic and electrophysiological responses within the brain. The subjects were instructed to judge whether visually presented…

Time is a constraint but also a condition of operating within a didactic system. Don't we need to distinguish several kinds of times? Our study will focus on teachers' time management strategies. We will identify these strategies by taking into account two temporal dimensions--didactic time and time capital--and the rate at which the former…

Learning sciences (LS) and instructional systems design (ISD) are two related fields that have shared interests in the application of technology for advancing human learning. While the two fields may have different values, boundaries, and in some cases methods, they also share significant overlap of content and purpose. We examine the relationship…

This article presents replies to published comments on the authors' original article (R. L. Sternberg, E. L. Grigorenko, and K. K. Kidd. G. Carey cited in his response to their article a study by Tang et al. (2005) showing that "of 3,636 subjects of varying race/ethnicity, only 5 (0.14%) showed genetic cluster membership different from their…

Transcripts of 784 psychology alumni from 4 universities revealed that students' timing of first enrollments in a statistics or methodology course was the result of an interaction between personal preferences and differences in program requirements. Where only a single methodological course was mandatory, first enrollments were especially late in…

In the present study, the authors tested the cross-ethnic validity of several variables and paths from a model of disordered eating proposed by T. L. Tylka and L. M. Subich (2004) with 200 Asian American college women. Path analysis indicated that this model provided an excellent fit to the data after a path from internalization of the thin ideal…

In 4 experiments, the authors addressed the mechanisms by which grammatical gender (in Italian and German) may come to affect meaning. In Experiments 1 (similarity judgments) and 2 (semantic substitution errors), the authors found Italian gender effects for animals but not for artifacts; Experiment 3 revealed no comparable effects in German. These…
