Declarative memory, or declarative knowledge is a type of long term
memory. It is the memory of specific facts and events. It can be thought of as knowing
what or knowing
that.
Contrast declarative memory with
procedural memory
Studies of amnesic patients have provided evidence that decclarative and non-declarative learning concepts seem to have distinct mechanisms within the brain. Amnesic patients are not able to retain long-term declarative memories, such as new factual information for anything more than a short time, but are able to learn non-declarative tasks and retain them for very long periods.
