“Time is essential to speech”
“Time is essential to speech.” This study by de Cheveigne (2003) makes clear that in order to understand speech, the brain depends upon its internal clock (or what is known as temporal processing) to decipher at a minimum: 1) whether the left or right ear heard it first or which direction the voice came from, 2) pitch and intonation or WHO is speaking, 3) each individual sound within each word, 4) how the sounds blend together to make each word, including whether each sound is a vowel, consonant, voiced, voiceless, and 5) whether there are pauses between sounds and words that add emphasis or meaning. When timing in the brain or temporal processing is off by just milliseconds, a person may have difficulty processing and understanding speech. Interactive Metronome is a patented program that addresses the underlying problem in Auditory Processing Disorders, tuning the internal clock to the millisecond in order to more accurately perceive speech.

Children with ADHD are frequently impulsive. Fortunately, researchers are trying to get to the bottom of this to determine the reason(s) why and what can be done about it. Authors of an editorial in the American Journal of Psychiatry (2006) remarked that watching the brain in action under MRI is helping researchers and doctors better understand the underpinnings of ADHD, or in other words, what is going on in the brain? Interestingly, the areas of the brain implicated in ADHD that are frequently targeted for study are ALSO part of the brain’s internal timing network. Timing in the brain is known to be disrupted in individuals with ADHD & has also been implicated in the ability to control one’s impulses and behavior. Interactive Metronome can be an important part of the treatment program for a person with ADHD by improving timing in the brain and addressing some of the areas of brain function mentioned in this article (i.e., working memory, ability to tune out distractions and pay attention to what is most important).
