The symmetry-induced numerosity illusion depends on visual attention

For the ST, ST-WD: each file contains a matrix called “a”. Each row of the matrix “a” is a trial. The columns contain the following information: 1st: Numerosity of test stimulus 2nd: Log10 of numerosity of test stimulus divided by the standard numerosity 3rd: Participant response (0 = standard stimulus; 1 = test stimulus) 4th: 200 5th: Standard numerosity 6th: Dots size in pixels 7th: 10 8th: Condition (0= symmetry condition; 1= random condition) 9th: Standard-Test order (1 = standard first; 2 = standard second) 10th: Response time 11th: -99 12th: -99 13th: -99 14th: 0 For the DT: each file contains a matrix called “a”. Each row of the matrix “a” is a trial. The columns contain the following information: 1st: Numerosity of test stimulus 2nd: Log10 of numerosity of test stimulus divided by the standard numerosity 3rd: Participant response (0 = standard stimulus; 1 = test stimulus) 4th: 200 5th: Standard numerosity 6th: Dots size in pixels 7th: 10 8th: Condition (0= symmetry condition; 1= random condition) 9th: Standard-Test order (1 = standard first; 2 = standard second) 10th: Response time to the numerosity task 11th: Response to the color-conjunction task (1: target; 0: no-target) 12th: code of color-conjuction stimulus presented onscreen 13th: Accuracy to the color-conjuction task (1:correct; 0:wrong) 14th: 1
