Comparative cognition is a field of study within psychology that focuses on comparing the cognitive abilities and processes of different animal species, particularly non-human animals, with the goal of understanding the evolution of cognition. Researchers in this field use a variety of methods, such as behavioral experiments, observational studies, and neural imaging techniques, to investigate how animals perceive, learn, reason, and solve problems. Comparative cognition research has implications for understanding the cognitive capacities of animals and the ways in which they may differ or overlap with human cognition. This field has also contributed to our understanding of the evolution of cognitive processes across species.
