DECLARATIVE MEMORY Meaning and
Definition
-
Declarative memory, also known as explicit memory, refers to a type of long-term memory that involves the conscious recollection of facts, events, and information that can be articulated or declared explicitly. It encompasses memories that can be consciously recalled and explained in words. Declarative memory is one of the two major categories of long-term memory, alongside procedural memory.
This type of memory includes both semantic memory and episodic memory. Semantic memory represents our general knowledge about the world, such as facts, concepts, and vocabulary. It allows us to recall information, definitions, or historical events without any specific context or personal experience. On the other hand, episodic memory refers to our capacity to recall specific events or episodes that have occurred in our lives. It is autobiographical in nature and involves the retrieval of personal experiences, including details about when and where the event happened.
Declarative memory is typically conscious and can be intentionally accessed by effortful retrieval. We often use strategies such as rehearsal, organization, and elaboration to encode information into declarative memory. This type of memory is primarily supported by the medial temporal lobe structures, including the hippocampus, as well as the prefrontal cortex and other neocortical regions.
In summary, declarative memory encompasses conscious memories of facts, events, and experiences that can be explicitly verbalized. It involves both semantic and episodic memory and is an essential component of our ability to learn, communicate, and navigate the world.
