This study caught our eye. Unfortunately we can't post a link to the original article as it is too 'new'. Although the way attention deficit disorder is sometimes referred to as a general attention or executive function disorder, many clinicians and scientists have also commented briefly about "hyperfocus", often in the setting of computer activities.
This small study of 9-12 year old children found that selective visual attention was just fine. What children had difficulty with was inhibiting motor responses (button clicks) when visual distractors were flashed on screen.
We would like to see if some of this work could be replicated with larger groups of children diagnosed with ADHD. There have been some large scale studies comparing behavioral interventions with medical treatment, but surprisingly few studies examining the best learning strategies for children diagnosed with ADD or ADHD. Today most clinical treatment trials are funded primarily by pharmaceutical companies, and fewer financial resources are available for studying non-medical or educational approaches.
