Exploring memory and mastery
The director of the Rolf Institute concluded our commencement speech with a statement that has baffled me for years: “Dr. Rolf encourages you to work toward mastery but to know that you will not truly be Rolfing until you’ve been in full-time practice for five years.” Although no one interrupted to ask what we would be doing during those early years as Rolfers, an uneasy vibe engulfed the room. Today, thanks to recent insights from the neuroscience and pop psychology communities, I’m gaining a better understanding of that graduation-day statement. I now believe Rolf was drawing on 50 years of experience in determining the amount of time it typically takes to move a therapeutic skill such as Rolfing from explicit to implicit memory.
My first clue came in 2008, when I read Malcolm Gladwell’s bestselling book “Outliers,” which outlines his 10,000-hour rule.1 Gladwell’s theory is that a person can only attain mastery of a subject or skill through 10,000 hours of practice, or about 90 minutes per day for 20 years. I quickly realized both Gladwell and Rolf were proposing a similar “practice makes perfect” theme and had set a theoretical time limit for mastery.
It’s true you can’t teach experience, but there seemed to be a missing piece to this puzzle — namely, a clear distinction between the quantity of hours spent practicing and the quality of that practice. I looked to the latest neuroscience studies to find out how the brain and body work together to memorize new skills, and whether there’s a way to hit fast-forward on the process of mastery.
From explicit to implicit memory
Our brains are very much like sponges. They are malleable and constantly adapting to peripheral input by strengthening existing neural connections and networks, a process called long-term potentiation (LTP). The more we use a particular neural network, the stronger it becomes, as we are reinforcing those brain map connections. For instance, I conclude each myoskeletal session with a routine called closing stretches. In that series of nine techniques, there’s one particularly tricky maneuver that requires focused attention. For years, as I approached this “torso-twist” stretch, I had to specifically remind myself to reach over and grasp client’s right arm and lift the scapula, slide left hand under scapula to elevate, and then lift and twist torso as my left hand pinned the client’s right ASIS (Image 1). One day, I realized I’d completed that complex maneuver without coaching myself through it. The years of practice had finally reinforced those neural circuits, allowing me to perform the skill unconsciously. This is LTP at work and it demonstrates the underlying cellular mechanism of learning and memory.
For years, that tricky closing stretch was a great example of explicit memory, or information we have to consciously work to remember. Eventually, the maneuver moved to implicit memory — information that can be remembered unconsciously and effortlessly. Also called procedural memory, implicit memory is the unconscious memory of skills and how to do things, particularly the use of objects or movements of the body, such as throwing a ball, playing guitar, or massaging a client’s shoulders. This is a functional form of memory that cannot be consciously recalled. Such memories are typically acquired through repetition and practice and are composed of automatic sensorimotor behaviors that are so deeply embedded we are no longer aware of them. Once learned, these “body memories” allow us to carry out ordinary motor actions more or less automatically, i.e., “the hands know more than the head.” The question is how did I move from explicit to implicit memory during that complex closing stretch, and is there a faster way to get there?
Multi-media learning speeds mastery
Today’s neuroscientists have discovered that implicit memories are primarily encoded and stored in the cerebellum and motor cortex, both of which are involved in motor control (Image 2), whereas explicit memories are predominately encoded by the hippocampus. For years, scientists erroneously believed all information on a particular subject — whether learned via reading, watching TV, or listening to an audio device — was compiled in a single area of the brain. Media theorist Marshall McLuhan was one of the first to disagree with this theory. In his classic book “Understanding Media,” McLuhan introduced the world to the idea that “the medium is the message.”2 Put simply, the manner in which information is communicated has more of a profound effect on the person receiving the information than the information itself. So, what does that mean for manual and movement therapists?
The takeaway is that tapping a variety of methods to learn and practice one’s skill set may be the fastest road to mastery. In other words, the most efficient way to move information from explicit to implicit memory is through multi-media formats, which include visual, touch, audio, and other sensory inputs. For example, participating in various hands-on workshops and research conferences exposes the brain to diverse viewpoints on the same subject, making learning more fun and engaging, and, therefore, more effective.
To expand your skill set, practice does make perfect, but the process can be speeded along by exposure to a variety of learning mediums, such as books, DVDs, audio recordings, and technique demonstrations from an array of educators. The brain loves novel stimuli, such as playfully practicing techniques while viewing yourself in a mirror or teaching a new routine to a partner. Adding emotion to your sessions through playful practice further stimulates the brain’s amygdala function, causing memories to move more quickly from explicit to implicit. Rolf was right when she implied that you can’t teach experience — but we now know the process of mastery can be accelerated.
