The polysialylated neural cell adhesion molecule (PSA-NCAM) has been implicated in activity-dependent synaptic remodeling and memory formation. Here, we questioned whether training-induced modulation of PSA-NCAM expression might be related to individual differences in spatial learning abilities. At 12 h posttraining, immunohistochemical analyses…

This paper, based on naturalistic data, describes the acquisitional course and use of the articles "a" and "the" in young English-speaking children (18-61 months), with special emphasis on the role of individual variation. A growth modeling approach to the data reveals that children's individual acquisition schedules are similar in trend, but vary…

Objective: To compare personality traits of psychiatry residents with various characteristics. Method: The authors administered Cloninger's personality inventory to residents at two schools. Results: There were no trait differences between international medical graduates (IMGs) and U.S. medical graduates (USMGs) or those for whom psychiatry was a…

Structural, mean- and individual-level, differential, and positive personality continuity were examined in 599 patients treated for major depression assigned to 1 of 6 forms of a 6-month pharmacy-psychotherapy program. Covariation among traits from the Five Factor model remained invariant across treatment, and patients described themselves as…

A sense of direction (SOD) computes the body's facing direction relative to a reference frame grounded in the environment. The authors report on three experiments in which they used a heading-recall task to tap the functioning of a SOD system and then correlated task performance with self-reported SOD as a convergent test of the task's construct…

Purpose: The purpose of this study was to investigate chorus reading's (CR's) effect on speech effort during oral reading by adult stuttering speakers and control participants. The effect of a speech effort measurement highlighting strategy was also investigated. Method: Twelve persistent stuttering (PS) adults and 12 normally fluent control…

The purpose of this study was to explore individual differences in children's tense onset growth trajectories and to determine whether any within- or between-child predictors could account for these differences. Twenty-two children with expressive vocabulary abilities in the low-average to below-average range participated. Sixteen children were at…

From the cognitive model of multimedia learning proposed by [Schnotz, W., & Barnett, M. (2003). Construction and interference in learning from multiple representation. "Learning and Instruction, 13", 141-156], two hypotheses regarding the learning of spatial arrangements of objects were derived: the integration hypothesis and the multiple source…

Analyzed 104 language samples obtained from 42 different normal language learning children at 15, 19, and 35 months of age for the proportional use of 11 grammatical morphemes. Wide variability was found among the samples in the proportional use of each morpheme. (49 references) (JL)

The influence of cognitive growth in working memory (WM) on mathematical problem solution accuracy was examined in elementary school children (N = 353) at risk and not at risk for serious math problem solving difficulties. A battery of tests was administered that assessed problem solving, achievement, and cognitive processing (WM, inhibition,…

Mentoring has long been recognized as an effective strategy for retaining and supporting doctoral students in their programs of study. In this qualitative investigation, we conducted three focus groups of proteges, peer mentors, and faculty mentors to explore definitions, experiences, and expectations of mentoring. Results indicated that the three…

Diversity in environmental institutions is of increasing concern to scholars and practitioners. The author examined student perceptions of the importance of 20 diversity and equity factors in their decisions to accept a job. A national sample of 1,239 students in 9 environmental disciplines (biological sciences, geosciences, natural resources,…

The recent No Child Left Behind legislation has defined a vital role for large-scale assessment in determining whether students are learning. Given this increased role of standardized testing as a means of accountability, the purpose of this article is to consider how individual differences in motivational and psychological processes may…

This article describes a qualitative study into student teachers' learning processes through changes in their interactive cognitions. First, theoretical propositions about the relation between learning to teach, professional development, and practical knowledge are defined. Next, the procedure to grasp interactive cognitions as part of practical…
