Purpose: Sentence comprehension deficits are common following a left hemisphere stroke and have primarily been investigated under optimal listening conditions. However, ample work in neurotypical controls indicates that background noise affects sentence comprehension and the cognitive resources it engages. The purpose of this study was to examine…

Perspective-taking plays an important role in daily life, allowing consideration of other people's perspectives and viewpoints. This study used a large sample of 265 community-based participants (aged 20-86 years) to examine changes in perspective-taking abilities--a component of "Theory of Mind"--across adulthood, and how these changes…

Response inhibition, selective attention, and working memory were the primary cognitive processes of interest. Method: Twelve healthy older and 12 healthy younger…

Adolescent cannabis use is associated with working memory impairment. The present randomized controlled trial assigned adolescents ages 14 to 21 enrolled in cannabis use treatment to receive either working memory training (experimental group) or a control training (control group) as an adjunctive treatment. Cognitive function, drug use, and other…

The SCWT (Stroop Color-Word Test) is a quick and frequently used measure for assessing selective attention and cognitive flexibility. This study determines age, sex and education level influence on attention and cognitive flexibility by CSCWT (Computerized Stroop Color-Word Test) among healthy Iranian children and adults. There were 78 healthy…

This study examined the independent and mediated associations between maternal depression symptoms (MDS), mother-child interaction, and child executive function (EF) in a prospective longitudinal sample of 1,037 children (50% boys) from predominantly low-income and rural communities. When children were 6, 15 and 24 months of age, mothers reported…

In a sample of 92 children aged 6-13 years this study investigates the normal developmental change in the relation between executive functioning (EF) and the core behavioural symptoms associated with attention deficit hyperactivity disorder (ADHD) (hyperactivity/impulsivity and inattention) as well as symptoms often co-occurring with childhood…

Objective: The main aim of this study was to examine the age-dependent remission from ADHD in girls transitioning through childhood into adolescence and early adulthood. Method: We conducted a 5-year prospective follow-up study of 123 girls with ADHD and 106 non-ADHD control girls aged between 6 and 17 years at ascertainment. ADHD was considered…

Ninety-six participants, who were younger (20 years) or older (68 years) adults and either monolingual or bilingual, completed tasks assessing working memory, lexical retrieval, and executive control. Younger participants performed most of the tasks better than older participants, confirming the effect of aging on these processes. The effect of…

Background: It has been proposed that ADHD is an executive control disorder. Little is known however about the maturation of executive control in ADHD. Method: A cross-sectional study of ADHD patients compared to normal controls tested on a computerized neurocognitive test battery. Participants: 175 patients with ADHD, age 10 to 29, compared to…
