Declarative

Declarative memory is the aspect of human memory that stores facts and experiences. It is so called because it refers to memories that can be consciously discussed, or declared. It applies to standard textbook learning and knowledge, as well memories that can be 'travelled back to' in one's 'mind's eye'. It is contrasted with procedural memory, which applies to skills. Declarative memory is subject to forgetting, but frequently-accessed memories can last indefinitely. Declarative memories are best established by using active recall combined with mnemonic techniques and spaced repetition.

Declarative Knowledge is knowledge of objects and facts. Also called declarative memory, this includes sensory knowledge. Declarative knowledge is essential in both interpreting the external world and in introspectively placing one's self in context.
