A bit of Research: The ability of Adults with ADHD to maintain a rhythm with a faster or slower tempo
Here is an interesting study by Gilden and Marusich (2009) published in Neuropsychology that looked at the ability of adults with ADHD to maintain a rhythm with either a faster tempo (less demand on focus, self-control, and working memory) or a slower tempo (more demand on focus, self-control, and working memory). Persons with ADHD had MUCH more difficulty when the tempo was slower, requiring them to estimate a longer time interval between beats, maintain the time interval in their memory, and restrain themselves from hitting too soon. This study, like many others, points to the direct relationship between timing in the brain and its command center “working memory.” Researchers theorize that Interactive Metronome is affecting this critical “control center” for timing in the brain and thereby improving many of the time-related symptoms of ADHD.
