False Memory in Adults With ADHD: A Comparison Between Subtypes and Normal Controls.

Objectives: To examine the performance on the Deese-Roediger-McDermott task of adults divided into ADHD subtypes and compares their performance to that of healthy controls to examine whether adults with ADHD are more susceptible to the production of false memories under experimental conditions.

Method: A total of 128 adults with ADHD (50% females), classified into three Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV-TR) subtypes, were compared with 48 controls.

Working memory subsystems are impaired in chronic drug dependents.

Background: A large body of research that has investigated substance dependence and working memory (WM) resources, yet no prior study has used a comprehensive test battery to examine the impact of chronic drug dependence on WM as a multi-component system.

Objectives: This study examined the efficiency of several WM components in participants who were chronic drug dependents. In addition, the functioning of the four WM components was compared among dependents of various types of drugs.

Measurement invariance of working memory measures across two Arab cultures.

A confirmatory factor analysis was performed to examine the factorial structure of a battery of working memory measures across two Arab cultures (Kuwait and Egypt). The battery of tests was administered to a sample of 384 children: 192 primary-school Kuwaiti children (96 boys, 96 girls; M age = 10.0 yr.

Exploring the central executive in situation awareness.

Despite its significance, the central executive is the least explored component of working memory, particularly in complicated contexts. Exp. 1 investigated the role of executive control of working memory in situation awareness in a real-life driving simulation.
