4.2 Cortisol and Threat Foregrounding
Human Behavior FCA
This page is structured as definition, control variables, causal chain, observable outputs, and boundary, and serves as a canonical definition node in Human Behavior FCA.
Cortisol increases the probability that threat-related input enters foreground processing.
This modulation raises threat-template weight in DMN and shifts foreground competition conditions.
Cortisol is a modulation axis, not DMN itself and not a standalone network.
Threat-input frequency.
Foreground-occupancy intensity.
DMN threat-template weight.
Compression level of FP available space.
ECN interruption probability.
Observable Output → Foreground Entry → Historical Template Matching and Explanation → New Structure Generation → Execution Maintenance → Feedback Update.
Cortisol primarily biases foreground entry and then reweights downstream interpretation and generation routing.
If feedback update does not recalibrate threat weighting, the chain stays biased under alert-like input.
Threat-related input is prioritized more often under comparable conditions.
Decision routing returns to defensive interpretation more frequently.
Execution interruption rate rises while update speed declines.
Do not write cortisol as DMN itself.
Do not replace chain analysis with emotion labels.
Do not use moral judgment to explain input bias.
