Serotonin-like signal
The stability channel of the affect state vector. High values bias the system toward consistency, caution, and established patterns. Low values increase receptivity to novel or disruptive signals. Counterbalances the dopamine-like channel's reward-seeking tendency.
The serotonin-like channel of affect state represents a kind of cognitive stability or contentment with the current state. When elevated - typically after sustained periods of positive outcomes and low contradiction - it biases the attention engine and policy engine toward established, well-validated patterns rather than novel exploration. It counterbalances the dopamine-like channel: where high dopamine-like signal increases appetite for novel and high-reward stimuli, high serotonin-like signal increases the weight of stable, consistent, proven approaches. The interaction between these channels shapes the system's moment-to-moment disposition. A system experiencing repeated success (high dopamine, rising serotonin) converges on consistent behavior. A system experiencing disruption or novel challenges (depressed serotonin, elevated norepinephrine) opens up to exploration and faster adaptation. The balance is not fixed; it responds dynamically to the operational environment.
