A multidimensional item response theory model that accounts for response style factors is presented. The model, a multidimensional extension of Bock's nominal response model, is shown to allow for the study and control of response style effects in ordered rating scale data so as to reduce bias in measurement of the intended trait. In the current…

In 3 experiments, the authors examined factors that, according to the source-monitoring framework, might influence false memory formation and true/false memory discernment. In Experiment 1, combined effects of warning and visualization on false childhood memory formation were examined, as were individual differences in true and false childhood…

In this article, the author offers suggestions for effectively addressing disability in and outside the classroom. She believes that a new vision for disability education that moves away from a limitations model and toward humanizing disabilities is crucial for campus communities. Through an introduction to universal design of instruction,…

The time-based resource-sharing model (P. Barrouillet, S. Bernardin, & V. Camos, 2004) assumes that during complex working memory span tasks, attention is frequently and surreptitiously switched from processing to reactivate decaying memory traces before their complete loss. Three experiments involving children from 5 to 14 years of age…

Newbrough's Third Position is discussed in terms of its utility as a framework within which to understand and resolve interpersonal differences, seemingly irresolvable diametric differences, and conflictual situations. The framework's essential elements and its application is illustrated through the presentation of a series of fictitious scenarios…

The increasing use of diary methods calls for the development of appropriate statistical methods. For the resulting panel data, latent Markov models can be used to model both individual differences and temporal dynamics. The computational burden associated with these models can be overcome by exploiting the conditional independence relations…

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…

Objective and subjective career success were hypothesized to mediate the relationships between sociodemographic variables, human capital indices, individual difference variables, and organizational sponsorship as inputs and a retirement decision and intentions to leave either the specialty of emergency medicine (EM) or medicine as output…

This article reviews current methods for evaluating models in the cognitive sciences, including theoretically based approaches, such as Bayes factors and minimum description length measures; simulation approaches, including model mimicry evaluations; and practical approaches, such as validation and generalization measures. This article argues…

Initiation of drug use and other risky behavior in preadolescence is associated with poor developmental outcomes. In this research, we examine models that ascribe the trajectory to (a) weak executive cognitive function (ECF), (b) early manifestation of externalizing problems, or (c) heightened levels of trait impulsivity. We test the explanatory…

Comments on the article by D. Nettle, who has clearly shown that evolutionary psychologists need to focus more attention on individual differences, not just species-typical universals. Such differences are not mere "noise," and evolutionary theory will gain by understanding how they are produced and maintained. However, by focusing on personality…

During social interactions, people's eyes convey a wealth of information about their direction of attention and their emotional and mental states. This review aims to provide a comprehensive overview of past and current research into the perception of gaze behavior and its effect on the observer. This encompasses the perception of gaze direction…

Explores the traditional model of fixed individual differences in intelligence and suggests that a more flexible and optimistic view of human capabilities is one that sees abilities as a form of developing expertise. Outlines five key elements of a model of developing expertise. (SLD)
