Vigilance Rhythm [0.18, 0.84]
A paced verification practice in which a user checks AI output at deliberate intervals rather than monitoring continuously, on the premise that spaced focused review sustains attention quality better than unbroken vigilance across long interactions.
Operational Definition
Graded condition characterizing how a user's verification activity is distributed over a session: the regularity and spacing of explicit verification acts. It is operationalized as the cadence or dispersion of verification events rather than as a single occurrence.
Measurement Schema
Proposed measurement protocol (not yet empirically validated): Behavioral-log analysis of verification-act timestamps within a session: the inter-check interval distribution (mean and coefficient of variation) could be reported as a cadence index, optionally paired with sustained-attention performance over time.
