The ecological context and fitness impact of categorical perception: a comment on Green et al.

Animals, including humans, must make sense of information, bombarding them from the enviroment, quickly and effectively. Categorical perception is one such process, and the evidence for it is increasing. We argue that the next step in the research of category-based decision making should be to study wild animals in the field and in behavioral contexts that have strong fitness-relevant impacts. We illustrate this point by the promise of categorical perception in the rejection of foreign egg colors by American robins (Turdus migratorius).
