The expert performance approach championed by Ericsson et al. provides a scientific way forward for research on giftedness, and offers exciting new ways to further one's understanding of the determinants of high ability within a particular domain of expertise. While the methods the authors use are commendable and are likely to further one's…

This paper looks at the paradox of how recognition of diversity through research into individual differences, in such areas as learning style, cognitive style and personality, has had the reductionist effect of promoting commonality. This has been the outcome of the competition between inventories; the reduction of diversity to characteristics…

Discomfort intolerance, defined as an individual difference in the capacity to tolerate unpleasant bodily sensations, is a construct recently posited as a risk factor for panic and anxiety psychopathology. The present report used a biological challenge procedure to evaluate whether discomfort intolerance predicts fearful responding beyond the…

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…

Replies to comments by R. J. Griffore and D. A. Newman et al. on the author's original article on test validity and cultural bias in racial-group assessment. Helms notes that, given that within-group variance exceeds between-groups variance, racial groups are probably simulating a psychological construct that is more strongly related to…

In this paper we describe a taxonomy of task demands which distinguishes between Task Complexity, Task Condition and Task Difficulty. We then describe three theoretical claims and predictions of the Cognition Hypothesis (Robinson 2001, 2003b, 2005a) concerning the effects of task complexity on: (a) language production; (b) interaction and uptake…

In analytic moral philosophy it is standard to use unrealistic puzzles to set up moral dilemmas of a sort that I will call Lockean Puzzles. This paper will try to pinpoint just what is and what is not problematic about their use as a teaching tool or component part of philosophical arguments. I will try to flesh out the claim that what may be lost…

Psychologists are applying growth mixture models at an increasing rate. This article argues that most of these applications are unlikely to reproduce the underlying taxonic structure of the population. At a more fundamental level, in many cases there is probably no taxonic structure to be found. Latent growth classes then categorically approximate…

Evidence suggests that a moderate amount of variance in patient outcomes is attributable to therapist differences. However, explained variance estimates vary widely, perhaps because some therapists achieve greater success with certain kinds of patients. This study assessed the amount of variance in across-session change in symptom intensity scores…

Reading in another language (L2) is a complex, multidimensional process dependent upon both reader-based and text-based factors. The purpose of this study was to investigate the roles of reader-based individual difference variables and of the text-based variable of genre in reading comprehension in French. The sample included 153 adult learners…

Introduction: In the present study we examined the differences in volitional strategy use (i.e., self-efficacy enhancement, negative-based incentives, and stress-reducing actions) and their relation to cognitive self-regulated learning strategy use (i.e., rehearsal, elaboration, organization, and critical thinking) in a sample of university…

This review of research on the learning, teaching, and assessment of L2 German published or completed between 2002 and 2008 may be particularly timely due to developments from within the profession as well as recent political changes which continue to have a strong bearing on the way L2 German is promoted, learned, taught and assessed. Far from…

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…

This study examined how individual, relational and environmental factors related to adolescent demand for HIV voluntary counseling and testing (VCT). A cross-sectional survey among randomly selected 16-19-year-olds in Ndola, Zambia, covered individual (e.g., HIV knowledge), environmental (e.g., distance), and relational factors (e.g., discussed…

As traditional pull-out programs for students who are identified as gifted and talented (GT) decrease in number, classroom differentiation is becoming more essential for general education teachers at the elementary level. Despite the importance of differentiation, teachers are still not implementing it on a regular basis. One strategy that may…
