What gaze direction can tell us about cognitive processes in invertebrates.

What gaze direction can tell us about cognitive processes in invertebrates. Biochem Biophys Res Commun. 2021 Jan 04;: Authors: Winsor AM, Pagoti GF, Daye DJ, Cheries EW, Cave KR, Jakob EM Abstract Most visually guided animals shift their gaze using body movements, eye movements, or both to gather information selectively from their environments. Psychological studies of eye movements have advanced our understanding of perceptual and cognitive processes that mediate visual attention in humans and other vertebrates. However, much less is known about how these processes operate in other organisms, particularly invertebrates. We here make the case that studies of invertebrate cognition can benefit by adding precise measures of gaze direction. To accomplish this, we briefly review the human visual attention literature and outline four research themes and several experimental paradigms that could be extended to invertebrates. We briefly review selected studies where the measurement of gaze direction in invertebrates has provided new insights, and we suggest future areas of exploration.
