EF Science

Latent variable analysis was used to determine that activity level associated with the central executive was significantly greater in the ADHD group.

This study is the first to demonstrate a functional relationship between ADHD-related activity and working memory demands, particularly on the central executive, in adults. Results are consistent with findings in children and refute the notion that excessive activity is a ubiquitous feature of ADHD unrelated to task demands.

with visuospatial tasks is the most valid measure of working memory between groups. The current study offers explanation for why previous studies did not find working memory deficits in children with ADHD and lends further support for working memory as a core deficit of the disorder.

The first theme, Peers, illustrates the importance preadolescents place on friends and underlines the influences of peers during this formative age.

The second theme, identity, focuses on the choices students make while searching to find a balance between giftedness and acceptance in the lifeworld of middle school.

The last theme, Outlook, reflects the importance placed on education by these students and their desire for relevant, authentic and challenging curriculum.

When environmental constraint upon participant activity was present, results indicated that BMI-derived weight category was positively related to sedentary fidgeting volume. When the environment did not constrain participant activity, relationships between BMI-derived weight categories and sedentary time (seconds), number of steps taken, stepping time (seconds), and stepping cadence (steps/min) were in the predicted direction, though none reached statistical significance.

The topographical similarity of excessive motor activity seen in both ADHD and anxiety disorders, as well as similar WM deficits, may indicate a common relationship between WM deficits and increased motor activity across psychopathology. However, to date, no studies have examined the possible relationship between WM deficits and objectively measured motor activity associated with anxiety. Consequently, the current study examined objectively measured motor activity associated with the WM system in adults with ADHD, adults with GAD, and healthy control (HC) adults.

These results suggest that clinical measures of EF may differ among children with ADHD and controls at average IQ levels, but there is poorer discriminatory power for these measures among children with above average IQ.

Posner, a neuroscientist at the University of Oregon who studies memory. Posner has conducted studies showing that even a few days of really good mindfulness meditation can alter the ability of the brain to focus. Physical exercise is also one common intervention that can help, too, especially with elderly people, he says. Meditation is helpful because, unlike “brain games” that train you to pay attention to one thing, its effects can generalize. If you engage in mindfulness meditation, there is evidence that it’ll help you focus better in general, not just be better at playing 2048, according to Giesbrecht.

I define executive function as “the ability to get things done - and not punch someone in the nose while doing it.” Executive function is a set of mental skills that help you get things done. It’s located in the frontal lobe of the brain, and can help you manage time, pay attention, multitask, and more. It’s also involved in a teen’s mental health, which we know is critically important to understand,
