They can use spatial cues such as a landmark's local position, global position and orientation, or they can use a landmark's non-spatial featural information. The objectives of this thesis were: 1) to determine the conditions under which rats process information separately or simultaneously; 2) to determine how rats process stimuli when previously fixed information becomes more variable; 3) to determine whether animals can use spatial information when a previously encoded non-spatial cue is occasionally eliminated. The results obtained from this research suggest that rats use two different types of processing as a function of variability of redundant information. Moreover, changes within trials were only disruptive for animals that encountered information that had not varied between trials. However, with continued exposure to within-trial changes, these animals' accuracy increased to levels comparable to animals presented with information that varied between trials.","abstract_html":"Animals use various spatial and non-spatial cues when navigating the environment.
