State-dependent memory

State-dependent memory or state-dependent learning is the phenomenon where people remember more information if their physical or mental state is the same at time of encoding and time of recall. State-dependent memory is heavily researched in regards to its employment both in regards to synthetic states of consciousness (such as under the effects of psychoactive drugs) as well as organic states of consciousness such as mood. While state-dependent memory may seem rather similar to context-dependent memory, context-dependent memory involves an individual's external environment and conditions (such as the room used for study and to take the test) while state-dependent memory applies to the individual's internal conditions (such as use of substances or mood).
