Summary:Spering and Chow comments on the paper of Knoll et al that introduces a highly original paradigm that allows to assess spatiotemporal integration of visual motion information using eye movements, a continuous natural response across primate species. The authors tested the three primate species which are the humans, macaques, and marmosets. They viewed a large display of continuously moving dots, forming an optic flow field that occupied most of the visual field of the observer. These dots moved toward or away from one point in the field [termed the focus of expansion (FOE). The combination with virtual reality technologies, in which observers could navigate toward the FOE, would allow studying the bidirectional relationship between the navigational behavior of an observer and motion signals in a virtual environment.
