The visual foveal radius increases as a function of ρ, which implies that, at larger distances, participants can foveate and discriminate multiple objects simultaneously. a Since ρ2 > ρ1, the FVR (also see inset) for ρ2 is larger. If the participant places the center of the foveal circle strategically during visual search, multiple objects (red circles) could be foveated simultaneously. b Schematic diagram of how the FVR is computed from the eye tracking data
