If you can recall the procedure for riding a bicycle, but do not remember the learning event itself, what have you lost? a. Procedural memory b. Episodic memory c. Semantic memory d. Declarative memory

The answer is **b. Episodic memory**.<br /><br />Here's why:<br /><br />* **Episodic memory** refers to the memory of specific events and experiences from your personal past. Remembering the actual event of learning to ride a bicycle (where you were, who you were with, how you felt) is an episodic memory.<br /><br />* **Procedural memory** is the memory of *how* to do things. You've retained this because you can still recall the procedure for riding a bicycle.<br /><br />* **Semantic memory** is general knowledge about the world. Knowing *what* a bicycle is falls under semantic memory.<br /><br />* **Declarative memory** encompasses both episodic and semantic memory – it's any memory you can consciously recall and describe. Since you can describe the procedure for riding a bike, your declarative memory regarding the *procedure* is intact, but the episodic component related to the learning event is missing.<br />
