Nondeclarative memory, also called implicit, sensorimotor, or procedural memory, operates without conscious recall. It allows us to automatically retrieve what we’ve already learned without having to relearn the steps. When we ride a bicycle, for example, we don’t think about the sequence of events required to make it move forward. The memory of riding a bicycle is so ingrained in us that we just hop on and pedal without breaking the process down into steps. These kinds of memories are not always easy to describe in words.
