This study aimed to test whether male and female rats might show differences in cue competition effects in a conditioned taste aversion (CTA) model. If our caveman ancestors ate tainted or poisoned food, it could kill them; however, through the process of conditioning, our ancestors learned quickly to avoid potentially deadly foods.

Taste-potentiated odor aversion is of particular relevance to the analysis of learning and conditioning because it seems to be contrary to the cue-competition effects (e.g., overshadowing) that are typically found when two or more CSs are paired with a US (Kamin, 1969; Pavlov, 1927).
