Abstract
Albino rats under moderate (18 h/day) or high (23.5 h/day) water deprivation were required to learn either a central door cue or peripheral wall cue simultaneous discrimination in a two-choice discrimination apparatus. Following this acquisition phase, a series of redundant-relevant cue trials with both door and wall cues were introduced. Animals were tested on the utilization of wall and door cues separately and on the dominance for each cue. Drive level only affected original discrimination acquisition of the peripheral wall-cue task. Moderate-drive animals were better able to learn the wall-cue discrimination than high-drive animals. In general, door-cue learners were able to utilize both cues but showed dominance for door over wall cues. Wall-cue learners, however, were only able to utilize wall cues and showed dominance for wall over door cues.
