ABSTRACT
Current psychological theories distinguish among different forms of long-term memory. One distinction is between declarative and procedural knowledge. Declarative knowledge refers to memory for verbalizable knowledge or propositions. It includes semantic memory, such as word meanings and general facts, and episodic memory, our autobiographical memory of specific events. In distinction, procedural knowledge underlies skilled behavior and the ability to quickly perform various cognitive, perceptual, and motor operations. In contrast to declarative’s “knowing that,” procedural is referred to as “knowing how.” Whereas declarative knowledge is typically shown by verbal recall of information, procedural knowledge is usually demonstrated by facilitated performance of behavior.
