Temporal Contiguity Training Schedule¶
A timing schedule — instantiates Co-Activation Coupling Design
Arranges when cue and outcome are presented — the interval between them and the spacing of repetitions — so they fall inside the window where joint activation actually binds them.
Whether two units bind is not just a question of that they co-occur but when. Present a cue and its outcome too far apart and the association never forms; cram all the repetitions into one block and it forms weakly and fades. The Temporal Contiguity Training Schedule is the mechanism that owns the clock: it sets the interval between paired elements so they land inside the co-activation window, and distributes the repetitions across time so the link consolidates durably. Its defining move is treating timing — the inter-element interval and the spacing of trials — as the design variable, independent of which pair is being trained or what rule updates the weight.
Example¶
A trainer is teaching a service dog to associate a specific sound cue with a "settle" behavior using a marker (clicker) signal. The content is fixed — cue, marker, behavior — but the association lives or dies on timing. Mark too late, even by a second, and the dog binds the marker to whatever it happened to be doing then, not the intended behavior; the co-activation window for this kind of binding is short. The schedule pins the marker to within a fraction of a second of the behavior so cue and outcome fall inside that window, and then spaces the training: several short sessions across days rather than one long drill, because spaced repetition consolidates the association far more durably than massing it.[n1] Same pair, same reinforcement — but the schedule is what decides whether the link forms cleanly or binds the wrong moment. It says nothing about which behavior to target or how the weight changes; it governs only the timing envelope.
How it works¶
The schedule controls two temporal variables. The inter-element interval places the cue and the outcome close enough in time that they fall inside the co-activation window — the bracket within which joint activity actually strengthens the link — since a pairing outside that window either fails to bind or binds the wrong thing. The spacing plan then distributes repetitions across time: spaced trials (expanding intervals, interleaving with other material) consolidate more durably than massed ones, at the cost of a longer calendar. It arranges when valid pairings are delivered; it takes the content of the pairing and the arithmetic of the update as given.
Tuning parameters¶
- Inter-element interval — the gap between cue and outcome. Too long and no binding; too short can blur which elements are being paired. The right value depends on the substrate's window.
- Spacing schedule — massed vs. spaced vs. expanding intervals. Wider spacing consolidates more durably but stretches the timeline and feels slower early.
- Interleaving — whether pairings are trained in blocks or shuffled with others. Interleaving builds more flexible, less context-bound links but is harder at first.
- Window tolerance — how strictly a pairing must fall inside the co-activation window to count as a valid trial.
When it helps, and when it misleads¶
Its strength is that it fixes a whole class of failures that no amount of repetition can fix on its own: associations that won't form because the timing is wrong, or that form but don't last because the practice was massed. It is the mechanism to reach for when the content is right but the link still won't stick. Its failure modes are mistuned intervals — too long and nothing binds, too short and the wrong elements bind — and impatience, since the spaced schedule that consolidates best is also the one that looks slowest and tempts a team into massing. The classic misuse is compressing a spaced plan into a single crammed session to hit a deadline, buying fast apparent learning that decays almost immediately. The discipline is to match the interval to the substrate's actual window and to protect spacing against the pressure to cram.
How it implements the components¶
co_activation_window— it sets the inter-element interval so cue and outcome land inside the window where joint activation binds them, and defines the tolerance for a valid pairing.repetition_and_spacing_plan— it distributes repetitions over time (spacing, expanding intervals, interleaving) to consolidate the link durably.
It owns the clock but not the content or the arithmetic: naming the pair to train (target_association_objective) is the Paired Activation Rehearsal Protocol's; the per-event weight change (local_update_rule) is the Association Matrix Update Rule's; and gating the pairing to a context (context_gate) is the Context-Gated Pairing Exercise's.

Editorial Notes¶
Form Classification¶
Form family: Experiment, Test & Rehearsal
Rationale: Temporal Contiguity Training Schedule operates as an active test, trial, simulation, drill, or rehearsal that generates evidence through a deliberate attempt or perturbation because it arranges when cue and outcome are presented — the interval between them and the spacing of repetitions — so they fall inside the window where joint activation actually binds them.
Independent corroboration: The frozen evidence defines Temporal Contiguity Training Schedule as 'Arranges when cue and outcome are presented — the interval between them and the spacing of repetitions — so they fall inside the window where joint activation actually binds them', so its operative form is Experiment, Test & Rehearsal.
Nearest alternative: Protocol, Workflow & Routine — Temporal Contiguity Training Schedule includes features of a repeatable ordered procedure or handoff sequence that coordinates action, but its defining operation is an active test, trial, simulation, drill, or rehearsal that generates evidence through a deliberate attempt or perturbation.
Review outcome: Independent reviewer agreement; medium confidence.
Origin Attribution¶
Primary origin: Psychology
Origin pattern: Single lineage
Present-day reach: Universal
Rationale: The defining operation is: Arranges when cue and outcome are presented — the interval between them and the spacing of repetitions — so they fall inside the window where joint activation actually binds them. In the psychology lineage, that operation is specifically evidenced by authoritative or primary work that treats cue-outcome temporal contiguity and interval scheduling as central variables in associative conditioning. This makes psychology the best historical origin, while the retained alternates document contributing methods and later applications rather than being mistaken for coequal origins.

- Systems Thinking & Cybernetics — Systems science's feedback, stock-flow, boundary, and regulation tradition provides a formative adjacent lineage for the same temporal contiguity training schedule operation.
Review resolution: The blind reviewers disagree on primary lineage (organizational_management versus psychology), so I adjudicated the mechanism rather than inheriting either label. The defining operation is: Arranges when cue and outcome are presented — the interval between them and the spacing of repetitions — so they fall inside the window where joint activation actually binds them. In the psychology lineage, that operation is specifically evidenced by authoritative or primary work that treats cue-outcome temporal contiguity and interval scheduling as central variables in associative conditioning. This makes psychology the best historical origin, while the retained alternates document contributing methods and later applications rather than being mistaken for coequal origins. The cited Field, Learning pathways in fear conditioning directly supports the mechanism-specific operation and its disciplinary lineage. I retain all independently explained historical alternates without a numeric cap. origin_mode=single_lineage records how the mechanism arose; domain_reach=universal separately records how broadly it can now be applied.
Encyclopedia synthesis: The exact catalogued form synthesizes established practice rather than reproducing a single standard historical label.
Review outcome: Researched adjudication after independent review; high confidence.

Notes¶
[n1] Classical (Pavlovian) conditioning — the strength of a learned cue→outcome association depends sharply on the inter-stimulus interval (temporal contiguity), and spaced practice consolidates associations more durably than massed practice. Both are the real timing effects this schedule is built to exploit. ↩
