A comparative psychologist investigates behavior and cognition by studying different species or populations. Comparisons can test whether a capacity depends on a particular sensory system, ecological problem or evolutionary history. For example, Nicky Clayton studied what, where and when information in scrub jay cache recovery. Similar task performance does not automatically establish an identical mechanism or subjective experience across species. [ref]
Episodic-like memory during cache recovery by scrub jays by Nicky Clayton and others. 1998, cache identity, location and elapsed-time experiment
A comparative psychologist who, with Anthony Dickinson, tested episodic-like memory in scrub jays. Birds recovered different cached foods according to where they had hidden them and how long ago, including whether a perishable food would have spoiled. The design tests integrated what–where–when information without assuming that birds report autonoetic consciousness.[ref]
