Individual Differences in the Drinking of Rats: The Role of Subject Characteristics in Schedule-Induced Drinking

  • Emöke Jozsvai


The relationship between subject characteristics and individual differences in schedule-induced drinking was examined in eight rats under ad libitum, massed, and intermittent feeding conditions. The results showed (a) marked individual differences in the magnitude of schedule-induced drinking (b) that correlated positively with tendency to drink during massed feeding in the experimental chamber, but (c) not with drinking in the home cages under ad libitum feeding, (d) Extent of schedule-induced drinking did not correlate with measures of activity.
