Psychostimulants also enhance the performance of executive functions in subjects with ADHD [ 9, 10] as well as in typically developed volunteers [ 11].
A correlation between the degree of activation in the above mentioned cluster and the behavioral performance of executive control revealed a Pearson coefficient = -.099 which was not significant (p =.19).
One study suggested that an age-related improvement in the performance of executive control tasks is paralleled by changing expression levels of DA and its receptor or gene [ 62].
For example, play may require simultaneous performance of executive tasks (decision making, dual tasking), visual attention tasks (multiple object tracking, distractor rejection), visuomotor tasks (e.g. navigating), and rapid object recognition.
It also has the responsibility to make decisions on issues of national importance such as socio-economic development plans (SEDPs) and budgets, and to provide oversight on the performance of executive bodies.
In conclusion, results from this study show that the DAT1 gene genotype can be a marker of performance of executive functioning (perhaps mostly working memory) in children with ADHD with those having the 9/10 genotype generally exhibiting a relatively poorer performance than those with the 10/10 genotype.
The sample for this analysis consisted of a subset of 155 women who consented and completed a 12-month randomized controlled trial of exercise (NCT00426881) that primarily aimed to examine the effect of once-weekly or twice-weekly resistance training compared with a twice-weekly balance and tone exercise intervention on cognitive performance of executive functions.
The total sample for this analysis consisted of 135 women who consented and completed a randomized controlled trial of exercise (NCT00426881; Brain Power study) that aimed to examine the effect of once-weekly and twice-weekly resistance training on cognitive performance of executive functions.

In order to get the best performance out of executives, these papers argued, it was necessary to align their interests with those of stockholders.
