Final answer:
Jon's ability to ride a bicycle after five years without practice is an example of muscle memory, which is when movements are remembered by the muscles through repetition (1).
Step-by-step explanation:
Jon hasn’t ridden a bicycle for five years; yet, when he hops on, he finds he can still ride. This is an example of muscle memory. Muscle memory refers to the phenomenon where specific movements become so familiar to your muscles through repetition that they can be performed without much conscious thought.
Skills like riding a bicycle, playing a musical instrument, or typing on a keyboard are all retained through muscle memory even after not performing them for a long time. This is because the procedural memory, a part of the long-term memory responsible for knowing how to do things, also known as motor skills, stores this information.
