Surprise: the neurochemical signal generated by prediction
Surprise: the neurochemical signal generated by prediction error when reality differs from expectation, serving as the primary learning trigger in biological systems and indicating a gap between one's internal model and external reality
Why This Is a Definition
This definition establishes surprise's genus (neurochemical signal) and differentia (prediction error indicating model-reality gap). It precisely distinguishes surprise from mere pleasantness or unpleasantness, grounding it in prediction error theory and the brain's learning mechanisms. It's a precise semantic boundary that answers what exactly surprise means in this curriculum context.
