Each change in the gallery resulted

Each change in the gallery resulted in a redistribution of visitor attention to all objects in the gallery.
For example, when more labels were added, the percentages of stops
at labels increased, but the total reading time decreased.
In addition, when the percentage of label readers increased by label changes, average total
time in the gallery for label readers declined, suggesting that the new label readers produced by making the labels more attractive didn’t influence the overall time in the gallery of these new readers.
