In 1985 Tulving introduced the remember-know procedure, whereby subjects are asked to distinguish between memories that involve retrieval of contextual details (remembering) and memories that do not (knowing). Several studies have been reported showing age-related declines in remember hits, which has typically been interpreted as supporting…

Recent neuroimaging studies have consistently ascribed the orbito-frontal cortex (OFC) a pivotal role in the pathogenesis of obsessive-compulsive disorder (OCD). Cognitive tests presumed sensitive to this region, such as the Object Alternation Task (OAT), are considered important tools to verify this assumption and to investigate the impact of…

This manual provides guidance and documentation for users of the longitudinal kindergarten-second grade (K-2) data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011). It mainly provides information specific to the second-grade rounds of data collection. Users should refer to the "Early Childhood…

In this paper we analyze the role played by self-confidence, modeled as beliefs about one's ability, in shaping task choices. We propose a model in which fully rational agents exploit all the available information to update their beliefs using Bayes' rule, eventually learning their true type. We show that when the learning process does not…

The goal of the present study was to report an instrument designed to determine students' mathematical performances and preference for visual or analytic thinking for the calculus derivative and antiderivative tasks as well as examine the relationships among students' cognitive style, cognitive ability, and mathematical performance in calculus.…

Many individuals who attempt to enter teacher education programs are precluded from doing so because of an inability to pass basic skills tests. The authors examine whether these tests are simply a gate that needs to be passed through or whether they provide useful early information about how individuals are likely to perform on subsequent…

Objective: To study the effect of administration sequence on Conner's continuous performance test (CPT-II) scores in clients requesting psychological assessment. It was hypothesized that when administered at the end rather than beginning of a test battery, the test scores will show higher symptom severity. If present, order effects may cause the…

The main challenge for theories of multitasking is to predict when and how tasks interfere. Here, we focus on interference related to the problem state, a directly accessible intermediate representation of the current state of a task. On the basis of Salvucci and Taatgen's (2008) threaded cognition theory, we predict interference if 2 or more…

There is general agreement that nonverbal animals and humans endowed with language possess an evolutionary precursor system for representing and comparing numerical values. However, whether nonverbal numerical representations in human and nonhuman primates are quantitatively similar and whether linear or logarithmic coding underlies such magnitude…

Recent interest has been drawn to the separate components of recognition memory, as studied by event-related potentials (ERPs). In ERPs, recollection is usually accompanied by a late, parietal positive deflection. An earlier, frontal component has been suggested to be a counterpart, accompanying recognition by familiarity. However, this component,…

The aim of the present study was to investigate the potential of the Working Memory Rating Scale (WMRS), an observer-based rating scale that reflects behavioral difficulties of children with poor working memory. The findings indicate good internal reliability and adequate psychometric properties for use as a screening tool by teachers. Higher…

The assessment of cognitive abilities, whether it is for purposes of basic research or applied decision making, is potentially susceptible to both facilitating and debilitating influences. However, relatively little research has examined the degree to which these factors might moderate the criterion-related validity of cognitive ability tests. To…

The achievement gap between middle class white students and black or Hispanic students living in low income households continues to be a persistent problem in education even ten years since the authorization of No Child Left Behind in 2001. This study examined the International Baccalaureate Middle Years Programme and how students from low income…

Research, carried out mainly in the period between the 1960s and 1980s, reported significant differences in the thinking styles of science and arts students. At this time university and school teaching was highly specialised and concern was expressed in the ongoing "two cultures" debate (Snow, 1959).Considerable changes have taken place in the…

Conservative Christian schools consistently earn higher standardized test scores than public schools while being criticized for using inferior curricular materials. This research investigates the effectiveness of Christian-published science textbooks in preparing students for the science reasoning subtest of the American College Testing. Data…
