ResumoTwo studies were conducted to investigate momentary lick rate in the albino rat as a function of age. In Experiment I, 24 albino rats were tested at 25, 35, 55 days of age in a longitudinal design. In Experiment II, two additional groups of 24 subjects each were tested, one only at 35 days and the other only at 55 days, to complete a cross-sectional design at the three ages. Lick rate was found to develop linearly as a function of age except that the cross-sectional males were somewhat slower at 55 days than at 35 days. These findings are consistent with our report that uninterrupted lick rates provide a sensitive measure for dipsogenic treatments and are in direct conflict with earlier reports that infant rats lick at adult rates.
