Temporal context & association

Recalling one thing pulls its neighbors with it — everything you learned in the same hour.

In the brain

Memories formed close together in time get linked. Recalling one tends to drag its neighbors along — the contiguity effectHoward 2002. A slowly drifting internal “context” is bound to each memory as it forms; reinstating that context reactivates everything you encoded in the same stretch. It’s why a smell can return an entire afternoon.

The model

The Temporal Context Model: a drifting context vector is associated with each item, and retrieval reinstates that context, which in turn cues temporally-nearby itemsHoward 2002. Association falls off smoothly with temporal distance.

In AI

engram returned “temporal siblings” — memories formed in the same session — alongside direct recall matches, and boosted the current project’s memories at session start (context-dependent retrieval by working directory); Counterparts generalizes this: memories that come to mind together get a typed edge, and recall spreads activation across those edges. Zep/Graphiti build an explicit temporal knowledge graph; PAM retrieves through temporal co-occurrence.

The map

Temporal association — §103 obvious (Temporal Context Model; PAM).

How an AI memory can do this

Every AI memory makes a choice about this mechanism, whether or not its makers name it.

Counterparts is an AI memory modeled on human memory; its home page shows each of its mechanisms, this one included. See it on the Counterparts home

The directory rates 12 AI memory systems on the same eleven mechanisms, in plain language and with sources.
