How many motion signals can be simultaneously perceived?

Edwards, Mark; Rideaux, Reuben


Previous research indicates that the maximum number of motion signals that can be simultaneously perceived is 2, if they are defined only by direction differences, or 3 if they also differ in speed or depth (Greenwood & Edwards, 2006b). Those previous studies used transparent, spatially-sparse stimuli. Here we investigate this motion-number perception limit using spatially-localised stimuli that drive either the standard or form-specific motion systems (Edwards, 2009). Each motion signal was...[Show more]
