Hello,
in a dot-probe experiment I want to present horizontally and vertically aligned dots. I have the problem that horizontal and vertical dots are not equally often presented.
So I first define the pictures
<picture dot.pic>
/items = ("DotHor.png", "DotVer.png")
</picture>
then I try to assign the pictures depending on some list-value (see attached files):
if (list.pos.tar.neg.right.nextvalue == 1) {picture.dot.pic.setitem("DotHor.png", 1); values.file.name = "DotHor.png";}
else if (list.pos.tar.neg.right.nextvalue == 2) {picture.dot.pic.setitem("DotHor.png", 1); values.file.name = "DotHor.png";}
else if (list.pos.tar.neg.right.nextvalue == 3) {picture.dot.pic.setitem("DotVer.png", 1); values.file.name = "DotVer.png";}
else if (list.pos.tar.neg.right.nextvalue == 4) {picture.dot.pic.setitem("DotVer.png", 1); values.file.name = "DotVer.png";}]
However, a frequency table shows that DotVer.png is presented more often than DotHor.png.
soa166 soa32 soa83 DotHor.png target.neg.left 0 0 0 target.neg.right 6 6 6 target.neu.left 6 6 6 target.neu.right 0 0 0 target.pos.left 0 0 0 target.pos.right 0 0 0DotVer.png target.neg.left 12 12 12 target.neg.right 6 6 6 target.neu.left 6 6 6 target.neu.right 12 12 12 target.pos.left 12 12 12 target.pos.right 12 12 12
Running the experiment several times gives always the same frequency table. I can not find the programming error. Suggestions are heartily welcome.
Best wishes Jens
