A new study would include a much larger participant base, with a wider range of demographics represented from the general public. This would help test the visual reception processes in different individuals, with varying ages and physical characteristics. By including a greater variety of age groups, this future research could help evaluate whether or not this integration of preconstancy and postconstancy processes changes over time, or whether it remains the same despite aging. Additionally, a new study would use of different shapes and colors as stimuli to complicate the grouping process even further. Participants would then be asked to group first by color, and then later by color and shape. With these differences in design...

For one, I believe that the addition of an additional characteristic to the stimuli (different shapes) may impact the time at which perceptual grouping occurs. I believe that perceptual grouping would take slightly longer, as the retina would have more characteristics to group, including both color and shape. This would show implications of the visual receiving process lagging when there are more external characteristics to group. Moreover, there might be slight or significant differences in the results of participants with different age groups. This would potentially impact that our processing systems tend to age as we age, and thus take more time in perceptual…
