A bit of research: Timing as an essential part of social communication

Timing in the brain is critical for communicating effectively or participating in group activities (i.e., sports, music, play). Some individuals wait until just the right moment to act, while others have a tendency to “jump the gun.” This may manifest in a penalty for a false start if playing football or social difficulty if a person constantly interrupts others when they are speaking. Miyake et al (2004) describe the neurological underpinnings of the tendency to make “anticipatory” timing errors like these in a paper published in Acta Neurobiologiae Experimentalis. Once we’ve learned a task or situation, we tend to respond as if on automatic pilot (without consciously thinking about it). But sometimes, something changes ever so slightly in the situation, and we must adapt and recalibrate our response. How well we do this depends upon our brain’s ability to perceive time…even in small increments like milliseconds. During the initial phases of Interactive Metronome (IM) training individuals with these timing-related problems often clap or move too fast (milliseconds ahead of the beat instead of on it), but soon become more in sync with the beat and with their peers.

A bit of research: Central Auditory Processing Disorder (CAPD)

Individuals with language-learning disabilities show slowed or delayed timing in the brain (in particular in the brainstem), so that they are not processing the timed or temporal elements of speech quickly enough to decipher sounds accurately and comprehend what is being said (also called temporal processing). Auditory Processing Disorder is at the heart of language-learning disabilities and is the leading cause of problems with learning to read and write. But there is hope!! Research shows that auditory processing (or the brain’s ability to understand speech & language) can be improved (Kraus & Banai, 2007). Interactive Metronome training targets the underlying problem with timing in the brain. Once mental timing is improved, the brain can process information in the speech stream more timely and accurately, leading to development of phonological skills that are so vital for auditory comprehension, reading and writing.

A bit of Research: The influence of timing in children with ADHD

A recent study by the Kennedy Krieger Institute (2011) showed that areas of the brain that control thinking and motor skills are different (smaller) in children with ADHD compared to other children. The specific regions of the brain that were mentioned are known to be involved in mental timing. Mental timing (AKA timing in the brain) is vital for many of our thinking skills and for good motor coordination. Studies have shown that timing in the brain is disrupted in children and adults with ADHD, leading to problems with focus, other cognitive abilities, and motor skills. Interactive Metronome, a patented non-medical treatment for ADHD, is the ONLY program that simultaneously works on thinking AND motor skills by specifically addressing and improving the areas of the brain responsible for mental timing.

A bit of Research: Autism Spectrum Disorder

There is still controversy over whether Autism Spectrum Disorders result from some interaction with environment after birth (i.e., toxic exposures, immune-modulation post-vaccination, etc) or whether they result from genetic defect(s). Some would argue both are contributing factors, that certain individuals are born with a genetic predisposition and that exposure(s) in the environment turn on or off certain genes that may contribute to the development of Autism Spectrum Disorders. In this study, researchers provide a strong argument for a genetic defect in the “clock genes,” genes that control our perception of time and with genes for a process called “methylation” that controls the turning on and off of our genes or how they are expressed (ultimately how they control our abilities). Individuals on the Autism Spectrum demonstrate numerous symptoms resulting from an impaired perception of time from circadian rhythm (sleep/wake/appetite) to millisecond timing required for speech-language, social/behavioral, cognitive, motor, and visual skills. The Interactive Metronome (IM) is a training program that is administered under the guidance of a certified professional. It is designed to improve the basic timing skills necessary for development of speech, language, cognitive, and motor skills. Many parents and professionals also report decrease in aggressive behavior, improved social skills, and better sensory processing following IM training.

A Bit of Research on TBI

The front portion of the brain, or frontal lobes, are particularly vulnerable to damage during accidents. Individuals with traumatic brain injury frequently have what is called a “frontal lobe injury.” This is significant because this area of the brain is responsible for so many important skills for successful community reintegration: our personality and mood, our ability to plan and organize events, to manage and monitor time, to focus our attention and problem-solve, to sequence and coordinate motor movements, and the list goes on and on…

Have you ever heard that ADHD is genetic?

Have you ever heard that ADHD is genetic? Ever notice that children with ADHD seem out of sync? Here is a research study by Nanda et al (2007) that supports this view and does so by showing that not only is timing in the brain disrupted in children with ADHD, but that it IS ALSO slightly disrupted in their siblings who do not have ADHD (when compared to children from families with no diagnosis of ADHD). From this and other studies, evidence shows that the more the brain’s timing skills are off, the more symptoms like impulsivity, hyperactivity, inattention, lack of organization, poor time-management, or difficulty with reading and other academic work are evident. The Interactive Metronome is a relatively easy, non-medical treatment program for ADHD that improves the brain’s critical timing skills and is tailored to each child’s specific needs.

A bit of Research: The role of Temporal Processing

Temporal processing (or the timing of neural oscillations/transmissions) plays a critical role in coordinated motor movement. In this paper published in Science, the authors distinguish between “continuous” motor tasks, which involves moving steadily and smoothly at a certain pace, versus “discontinuous” motor tasks, which involve a succession of stops and starts as a person accomplishes each step of an overall goal (i.e., picking up a plate, walking it over to the table, and setting it down). They discuss the role of the cerebellum in each of these types of motor tasks and how the timing control for each differs in terms of the brain structures used, arguing that the cerebellum is involved only early on in setting the timing goal for continuous, smooth movements, but that the cerebellum is involved throughout the movement when it is discontinuous or involves several starts and stops by setting several, successive timing goals. Timing in the brain may be disrupted due to developmental disorder, trauma, or illness resulting in uncoordinated movement and/or cognitive impairment. The Interactive Metronome is a treatment program that measures and improves temporal processing, or timing in the brain, that is critical for movement and thinking.

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.

Does IM really help with ADHD?

Dr. Stanley Greenspan, a noted expert in autism and child development/disorders, and his team of researchers conducted a study to see whether Interactive Metronome (IM) was a beneficial treatment for children with ADHD. They compared boys who received IM to boys who received either no treatment at all or boys who only played video games to try to improve their ability to focus. They found that those children with ADHD who received IM did far better than those that did not, with significant improvement in the areas of attention, motor skills, language processing, reading, and self-control (i.e., less aggressive behavior).
