The practice of mindfulness is increasingly being integrated into contemporary clinical psychology. Based in Buddhist philosophy and subsequently integrated into Western health care in the contexts of psychotherapy and stress management, mindfulness meditation is evolving as a systematic clinical intervention. This article describes…

Event-based prospective memory involves remembering to perform an action in response to a particular future event. Normal younger and older adults performed event-based prospective memory tasks in 2 experiments. The authors applied a formal multinomial processing tree model of prospective memory (Smith & Bayen, 2004) to disentangle age differences…

H. Bosch, F. Steinkamp, and E. Boller's (see record 2006-08436-001) review of the evidence for psychokinesis confirms many of the authors' earlier findings. The authors agree with Bosch et al. that existing studies provide statistical evidence for psychokinesis, that the evidence is generally of high methodological quality, and that effect sizes…

Our research on learning enhancement has been focusing on the consequences for learning and forgetting of some of the more obvious and concrete choices that arise in instruction, including: How does spacing of practice affect retention of information over significant retention intervals (up to two years)? Do spacing effects generalize beyond…

Differing theoretical approaches to the study of emotions are presented: emotions as private (psychodynamic approaches); emotions as sociocultural phenomena (social constructionist approaches); and a third perspective (interactionist approaches) transcending these two. These approaches have important methodological implications in studying…

This report focuses on prospective secondary mathematics teachers' understanding of irrational numbers. Various dimensions of participants' knowledge regarding the relation between the two sets, rational and irrational, are examined. Three issues are addressed: richness and density of numbers, the fitting of rational and irrational numbers on the…

Objective: To examine factors associated with eligibility and randomization and consider the efficiency of recruitment methods. Method: Adolescents, ages 12 to 17 years, were telephone screened (N = 2,804) followed by in-person evaluation (N = 1,088) for the Treatment for Adolescents With Depression Study. Separate logistic regression models,…

In their article, "Disconfirmation of the Predictive Validity of the Self-Appraisal Questionnaire in a Sample of High-Risk Drug Offenders," criminologists Mitchell and MacKenzie (2006) purported to evaluate psychometric properties of the Self-Appraisal Questionnaire (SAQ), the first self-report risk/need measure estimating violent and nonviolent…

The word length effect has been a central feature of theorising about immediate memory. The notion that short-term memory traces rapidly decay unless refreshed by rehearsal is based primarily upon the finding that serial recall for short words is better than that for long words. The decay account of the word length effect has come under pressure…

Although research has clearly established that low family income has negative impacts on children's cognitive skills and social-emotional competence, less often is a family's experience of material hardship considered. Using the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (N=21,255), this study examined dual components of…

The present paper explores the conceptual limitations of the bully discourses that ground UK anti-bullying policy frameworks and psychological research literatures on school bullying, suggesting they largely ignore gender, (hetero)sexuality and the social, cultural and subjective dynamics of conflict and aggression among teen-aged girls. To…

When using item response theory (IRT) models in educational and psychological measurement, it is standard practice to estimate the operating characteristics of test items from examinees' item responses alone. This is the final report of a project that employed Bayesian and empirical Bayesian methods to exploit additional information that is often…

Researchers interested in social power in organizational contexts have focused on investigating whether situational factors affect people's preferences for types of influence tactics. The persuade package is defined as a small standard set of methods (influence tactics) that leads to a particular goal (persuade the target to do something). The…

Four experiments investigated college students' judgments of inter-event contingency. Subjects were asked to judge the effect of a discrete response (tapping a wire) on the occurrence of a brief outcome (a radio's buzzing). Pairings of the possible event-state combinations were presented in a summary table, an unbroken time line, or a broken time…
