Providing a research-validated, evidence-based framework for designing effective distance learning experiences and environments is a current challenge to those interested in using this technology effectively with adolescents. This article offers the Learner-Centered Psychological Principles (LCPs) developed and disseminated by the American…

The authors present a reconciliation of 3 distinct ways in which the research literature has defined overconfidence: (a) overestimation of one's actual performance, (b) overplacement of one's performance relative to others, and (c) excessive precision in one's beliefs. Experimental evidence shows that reversals of the first 2 (apparent…

The success of a virtual learning environment (VLE) depends to a considerable extent on student acceptance and use of such an e-learning system. After critically assessing models of technology adoption, including the Technology Acceptance Model (TAM), TAM2, and the Unified Theory of Acceptance and Usage of Technology (UTAUT), we build a conceptual…

The problem investigated in this research study relates to the referral rate for special education evaluations between students of teachers who were exposed to the professional development and resources associated with the federally funded Reading First program and students of teachers who were not exposed to the program. The purpose of this study…

This study investigated the complex influences of individual differences and school contexts on the growth of mathematical reasoning skills in high school, with particular emphasis on differences in academic preparation, demographics (i.e., race/ethnicity, gender and socioeconomic status), and school characteristics. Students' growth of…

While public attention remains focused on the highest unemployment numbers in a generation, New York City is drifting toward a structural crisis with which policy makers could be grappling long after the recession fades to a bad memory. Even as the concerns about financial capital that spurred the downturn begin to subside, public officials must…

The present study examined consistency and inconsistency in adolescents' ethnic identification (i.e., self-reported ethnicity) across the 6 middle-school semesters. The sample (N = 1,589, of whom 46% were boys and 54% were girls) included African American, Asian/Pacific Islander, Caucasian/White, Latino/Latina, Mexican/Mexican American, and…

Age-normed tests of listening comprehension, oral expression, reading comprehension, and written expression were administered in Grades 1 (n = 128), 3, and 5, or 3 (n = 113), 5, and 7. Confirmatory factor analyses compared 1- and 4-factor models at each grade level and supported a 4-factor model of language by ear, mouth, eye, and hand. Multiple…

Studies 16 three-year-olds' and 17 adults' hedonic reactions to odorants by using a forced-choice procedure embedded in a simple game. Analyses revealed essentially the same pattern of preferences in both groups. In general, the odorant was a much better predictor of its hedonic quality than was the age of the subject. (RJC)

The problems of having two members of the same family working in a school are discussed. (CK)

Administered Raven's Advanced Progressive Matrices to 22 adults and measured cerebral glucose activity as subjects viewed videos on 2 occasions. Data provide evidence that individual differences in intelligence correlate with brain function even when the brain is engaged in non-reasoning tasks. (SLD)

The present study was designed to investigate extraversion-related individual differences in the speed of transmission of sensory input into motor output. In a sample of 16 introverted and 16 extraverted female volunteers, event-related potentials, lateralized readiness potentials (LRPs), and electromyogram (EMG) were recorded as participants…

This commentary focuses on the papers by Nurmi and Aunola and by Spinath and Spinath. I discuss the difficulty in testing the hypothesis that ability self concepts influence developmental changes in learning and task motivation. I point to the following concerns: (1) the difficulty in conceptualizing and then measuring these concepts well; (2) the…

In opposition to conceptualizing working memory (WM) in terms of a general capacity, we present four experiments that favor the view that individual differences in WM depend on attentional control. High- and low-WM participants, as assessed by the operation span task, learned unrelated sentences for which the subject and predicate of the sentences…

The present study examined gender schema encoding (activation of gender stereotypes) in the absence deliberate purposes relating to people (stereotype application). A release from proactive interference short-term-memory task was used. College (Experiment 1) and sixth-grade (Experiment 2) participants were asked to retain item identity and…
