2 pounds need to be added for Julia to notice any additional weight. The Weber fraction notes that there is a linear relationship between the proportion of the amount added and the just-noticeable difference to any sort of stimulus. In this way, it is easier to notice a change in a small stimulus than it is for a larger one.
