Prewatered, less thirsty rats were better able to utilize a redundant striped orientation cue, whose attributes had initially predicted water and 10% sucrose than post-watered, more thirsty animals. Deprivation during the original redundant-relevant discrimination rather than during the transfer task affected the acquisition of the transfer task. These findings indicated that drive affects the validity of a cue by determining the importance of incentives predicted by that cue.
