Repetition, Emotional Intensity, and TM–BM Resonance: How Strong Memory Nodes Form and Trigger Automatic Recall

This preprint explains why certain long-term memory nodes become extremely strong, easily matched to present situations, and repeatedly recalled. The core claim is that repetition (frequency/exposure) increases a memory node’s accessibility, while emotional intensity (fear, shock, joy, shame) creates deep imprints that resist decay. When repetition and intensity combine, these memory nodes gain dominant activation weight and can be triggered automatically by minimal cues (words, tone, facial expressions, locations).Key ConstructsTemporary Memory (TM): current impressions, sensory input, imagination, and context.Bold Memory (BM): long-term emotional signatures and conditioned patterns.Resonance (Match): present TM overlaps with stored BM signatures, producing fast recall and emotion.Resonance FormulationA bounded emotional output is modeled as: E₀ = tanh( TM · BM − D + Λ ) where TM · BM is the resonance score (overlap/match), D is decay (weakening without reinforcement), and Λ represents stabilizers/modulators (e.g., meaning, system stability, truth checks, and narrative effects).Included ContentExamples: childhood threat conditioning (unknown/undefined threats), trauma-like cue activation, repeated warnings, rumor persistence.Analogies: dirt-path-to-highway reinforcement, hot-stamp imprinting, alarm sensitization, and autocomplete bias.Diagrams: reinforcement flow (repetition + intensity), trigger-based recall, weak vs strong pathway selection, and impact vs truth.Practical ImplicationsParenting & education: repeated fear-based threats can create strong long-term threat signatures even without real events.Mental well-being: automatic fear may reflect learned resonance rather than present danger.Human-facing AI: systems should avoid amplifying repeated fear signals and should preserve stable, safe long-term memory behavior.
