Another study linking distorted time-processing and ADHD. Click here and here for posts about other related studies. What I find interesting is that the various experimental timing measures used in these studies could easily be made into psychometric tests (with readily available technology) for inclusion on intelligence tests or other special purpose cognitive batteries. Also, I have hypothesized in a MindHub Pub that some emerging neurotechnologies may improve ADHD (and related symptoms like attentional control and working memory) due to the fine-tuning of the human brain clock.
Other ADHD related research (brain connectivity, etc) can be found here.
