Examples of stimuli for adaptation number 3. The first two adaptation stimuli together indicate the six fixed locations in this run. The next four stimuli are random variations of these same six locations. In these stimuli, individual item size in the adaptation stimuli was decorrelated from numerosity, and luminance of the display was equated across the deviant stimuli. In another run (stimuli not shown), the control of non-numerical parameters was reversed.
