Timing influences Auditory Processing and Speech

Timing skills play a pivotal role in the development of speech production and perception, or the ability to speak and understand the speech and/or intent of others (Kello, 2003). Not only must a child rapidly decipher the timing characteristics of each individual sound, syllable, word, and phrase in the speech stream, but for successful communication to occur there must be precisely timed coordination between centers of the brain for language and cognitive processing or thinking skills and the muscles and structures of the mouth and throat (or voice box). On top of that, a child must process and understand other information associated with what is said, such as demeanor of the person (Is he happy? Angry? Sad? ) or humor (Was he serious? Or was he joking?) Many children on the Autism Spectrum either don’t understand what you said, or don’t understand the unspoken social aspects of speech. All of this depends upon timing in the brain!!! That’s a bit like patting your head and rubbing your tummy at the same time! However, in normal development the brain’s “internal clock” functions very precisely so that children learn to speak intelligibly and understand you when you speak to them, including your mood and intent. Interactive Metronome (IM) training impacts the very critical timing centers of the brain necessary for effective communication & social skills.

A bit of Research: Music and Rhythm in CAPD

Infants, before than can speak, are exposed to rhythmic sounds in the form of music and song. This research by Bergeson and Trehub (2006) shows that their little tiny ears and developing brains are already tuned just like an adult’s to hear the slightest changes in tempo, tone, and rhythm. They discuss the importance of the brain’s “internal clock” as it relates to how infants respond and move their bodies to music and other rhythms. IM providers who specialize in infant care and early intervention are reporting very good results when using the Interactive Metronome in the treatment of infants and young children who have developmental delays or disorders with improvements in the areas of: sensory processing, pre-speech/cognitive development, and motor skills. Case studies can be found at www.interactivemetronome.com

A bit of Research: Children with ADHD have an impaired sense of time?

Humans perceive time. We use this ability to predict what is coming, to think about how we will react, and then to respond in a timely fashion. It is well-documented that children with ADHD have an impaired sense of time. Areas of the brain that control our perception of time are affected in children with ADHD (i.e., working memory). In an article published in the Journal of Child Psychology and Psychiatry, researchers found that children with ADHD who also have a Reading Disorder have even more difficulty with timing skills. Research has shown that Interactive Metronome, a training program that addresses the underlying problem with timing in the brain, improves symptoms of ADHD and reading.

A bit of research: Have you ever heard the saying “timing is everything?”

Have you ever heard the saying “timing is everything?” Our brain keeps time – in microseconds, milliseconds, seconds, minutes, hours. This time-keeping function is critical for all of our human abilities and thinking skills. According to research, persons with musical training tend to consistently demonstrate better timing and rhythm than those who are not musically oriented. Children who play an instrument or are otherwise musically trained tend to also perform better in school, are focused, and complete projects on time. Here, Eck & Scott (2005) discuss the critical timing skills involved in the perception and creation of music. It is not surprising that musicians have better timing skills, and thus are more equipped to handle academic hurdles. Do you see the connection? If a child is struggling with school work, to focus or stay on task, has behavioral outbursts, is impulsive, or has trouble staying organized or managing time … the brain’s clock may be out of sync and areas of the brain may not be communicating efficiently or effectively, therefore the child may also be out of sync with other people and events in his/her environment. Interactive Metronome is the only treatment program that provides training and feedback in order to improve timing skills that are so critical to academic and social success.

A bit of Research: Are timing genes in the brain in some way flawed in children with Autism?

Researchers (Nicholas et al, 2007) are asking whether genes responsible for timing in the brain are in some way flawed in children with Autism (including High Functioning Autism and Asperger’s). Individuals on the Autism Spectrum display a significant number of symptoms that show timing in the brain is severely disrupted, from difficulty with sleep to the brain’s ability to process information, to attention or the ability to switch from focusing on one thing to another (they often become fixated), to communicating & reciprocating in conversation, to sensory processing and integration, to motor coordination (including the muscles for vision and visual perception). The authors found that there is indeed a case to be made that “clock genes” are involved, however they urge further research. More and more professionals are including Interactive Metronome in their comprehensive treatment programs for children on the Autism Spectrum in order to improve the timing skills that are critical for development of speech & language, cognitive, social, and motor skills.

“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.

Alertness versus focus: Same or different?

Alertness versus focus: Same or different?

Often upon completing a brief description of the benefits of IM to an individual, which centers on the benefits of increased controlled attention or “on demand focus”, people often ask me why not just drink one of those highly advertised energy drinks. These drinks claim to increase alertness, attention, energy and focus. Drinking an energy drink is much easier when compared to committing to IM training for three weekly hour sessions over a period of 4-5 weeks

In general, the primary claim of these energy drinks is increased alertness. Thus, it is important to understand that alertness is not the same as controlled attention or focus. Given all the claims circulating in the “cognitive enhancement” market place (energy drinks, brain fitness technologies), it is important that the discourse be scientifically-based and grounded in a professional consensus of terms. So let me attempt to add some order to the increasing confusion of terms.

I first turn to the highly respected Annual Review of Psychologyfor an article published by Posner and Rosthbart (2007).Their comprehensive research review makes a distinction between three different attention networks—alerting, orienting, and executive attention. These three different attention networks are orchestrated by different areas of the brain (see figure below). They also differ in the primary neurotransmitters utilized by each system—alerting (acetylcholine), orienting (norepinephrine), and executive (dopamine). Although related and often working collaboratively, they are different forms of attention.

A good tip from research on ADHD

In order for a child to have good self-control (i.e., behavior), the timing system in the brain must be operating normally. Faulty timing is at the heart of ADHD. Researchers in Australia recently developed a set of questions for parents of children with ADHD that will help doctors and therapists better pinpoint whether there is a problem with timing skills and whether or not they are getting better with treatment. This is a valuable tool for professionals who use Interactive Metronome in the treatment of ADHD to measure and document the effect of the treatment, which improves timing in the brain.

You are a time machine

p>You are a time machine

Time and space are the two fundamental dimensions of our lives. All forms of human behavior require us to process and understand information we receive from our environment in either spatial or temporal patterns. Even though mental timing (temporal processing) research is in a stage of infancy (when compared to spatial processing) important insights regarding the human brain clock have emerged.
Below is a list (albeit incomplete) of some of the major conclusions regarding the human brain clock. The sources for these statements come from my review of the temporal processing and brain clock literature during the past five years. Most of this information has been disseminated at the Brain Clock blog or the Brain Clock Evolving Web of Knowledge (EWOK). The goal of this post is to provide a Readers Digest summary of the major conclusions. This material can serve as a set of “talking points” at your next social event where you can impress your friends and family as you explain why you use the high-tech IM “clapper” (with a cowbell tone no less) either as a provider or as client.
Our brains measure time constantly. It’s hard to find any complex human behavior where mental timing is not involved. Timing is required to walk, talk, perform complex movements and coordinate information flow across the brain for complex human thought. Think about moving your arm and hand to grasp a coffee cup.   The messages to perform this task originate in your brain, which is not directly connected to your arm, hands and fingers. The ability to perform the necessary motor movements is possible only because the mind and extremities are connected via timing. Precisely timed neural messages connect your brain and extremities.   You are a time machine.
