Individual data for each group in Experiment 1. The data are the percentages of selection of the more-often-selected and less-often-selected stimulus elements in the distractor and no-distractor conditions in Experiment 1. Age group (in years) is denoted by number: 1  =  18–22; 2  =  47–55; 3  =  70–80.
