It is intended as a descriptive rather than normative measure, applicable across sensory modalities and experimental contexts.
The coinage combines perceiver and bar (as in barometer), signaling a threshold or index of observer influence.
Operationally, a perceiverbar would be estimated by modeling responses with predictors tied to the stimulus (intensity,
