Scaling the duration of short pauses in licking behavior of rats and mice: A first approximation to a basic pause-scaling unit

Two studies are reported in which short pauses from the drinking behavior of four hooded rats (rat study) and four mice (mouse study) were analyzed. Both of these studies supported the hypothesis that the interlick interval (II) can be used as a unit (PU) for scaling short pauses in licking behavior during water drinking. The outcomes of these studies are seen as suggesting that the factor responsible for the constancy of the II is also functioning during short pauses and is responsible for the tendency herein reported for pauses to be scaled by the PU.
