The HED Task Catalog is under development. IDs are not stable until formal release. Comments are welcome at github.com/hed-standard/hed-task/issues.

Long-Term Memory

Scope: Encoding, consolidation, retrieval; recall and recognition; recollection and familiarity; source memory; episodic, semantic, autobiographical, verbal memory; pattern completion and separation; proactive and retroactive interference; forgetting; directed forgetting; reconsolidation; prospective memory.

Out of scope: “Memory” as an umbrella; semantic representation itself (that lives closer to Language as semantic knowledge); short-term storage (Short-Term and Working Memory).

Note

Open issues: The recollection / familiarity / source-memory sub-distinctions are preserved as separate rows. Further sub-splitting (e.g., recollection by domain) is deferred.

This category contains 21 processes.
