Riding a bicycle can produce examples of many of the types of long-term storage described above. Talking about biking with someone else involves semantic memory (‘‘The frame I have is made of space-age materials!’’) or episodic memory (‘‘That day I was pushing hard to get to the top of a very steep hill, when I crashed.’’). Declarative memory is illustrated by knowing facts about bicycles (‘‘Many bikes today have at least 18 gears.’’), while procedural knowledge is shown when one actually rides a bicycle (the skill or motor performance). Recognizing landmarks that identify when to make turns and unconsciously doing so while talking about another topic with a riding partner illustrates implicit memory. Actually naming the roads that made up the route that was ridden that day, a conscious effort to recall each one, is evidence of explicit memory.
