Musclememory, otherwise known as motor learning, refers to the act ofencoding, storing, and retrieval of information in mind procedurallyand repeating it from time to time until it starts to happen withoutapplying any conscious effort. The phenomenon is mostly evident intyping of personal information numbers or passwords, riding abicycle, and playing musical instruments, among other examples. Thedegree of mastering a process is directly dependent on the practicewhich influences coordination between the motor neurons and themuscles responsible for effecting such actions. In the case of SarahKeller`s, therefore, it becomes interesting to study and analyze thewhole scenario, and probably ask a few questions.
SarahKeller`s experience falls under the category of fine motor memory asit involves the use of a tool, just like the usage of a toothbrush ora pencil. A repeated action of moving the instruments back and forthresults in a series of programs which cause motor cortex to beactivated, giving rise to the motor movements (Heun et al., 2013).However, retention of some skills of the patterned movements of thefinger is vulnerable to disruption if we learn another pattern withinsix hours from the previous one. The susceptibility reduces when anindividual does the second outside the six hours bracket. Ten yearsis a long duration enough to cause muscle memory (Sharples et al.,2016). The questions, therefore, are: What fraction of a day does shespend handling these tools? Does she disrupt the activity as perabove explanations?
Inconclusion, muscle memory is a purely physiological process whichinvolves brain or the central nervous system`s coordination. Themethod is advantageous when it helps one to remember effectiveexercises like cycling after an extended period and when someone canmaster the keyboard and subsequently type without necessarily lookingat the keyboard (Walsh, 2013).
