Hello,

ok, when I use setitem the probe is displayed with "".

<trial t.neg.word.left>
/ontrialbegin = [if (list.posi.probe.neg.left.nextvalue == 1)      {text.probe.left.hposition = values.links; values.pos = values.links; text.probe.left.setitem("F", 1)}
                  else if (list.posi.probe.neg.left.nextvalue == 2) {text.probe.left.hposition = values.rechts; values.pos = values.rechts; text.probe.left.setitem("F", 1)}
                  else if (list.posi.probe.neg.left.nextvalue == 3) {text.probe.left.hposition = values.links; values.pos = values.links; text.probe.left.setitem("J", 1)}
                  else if (list.posi.probe.neg.left.nextvalue == 4) {text.probe.left.hposition = values.rechts; values.pos = values.rechts; text.probe.left.setitem("J", 1)}]
/stimulusframes = [ 1 = fixation; 30 = maske; 31 = neg.word.left.tar, neg.word.left.dis; 42 = maske; 43 = probe.left ]
/validresponse = ("F", "J")
/iscorrectresponse = [if (text.probe.left.currentitem == "F") {values.korrekt = 33} else {values.korrekt = 36}]
/timeout = 3000
</trial>

In your <trial> elements, you are constantly *inserting* items into the probe <text> elements:

<trial t.neg.word.left>
/ ontrialbegin = [if (list.posi.probe.neg.left.nextvalue == 1)      {text.probe.left.hposition = values.links; values.pos = values.links; text.probe.left.insertitem("F", 1)}
                  else if (list.posi.probe.neg.left.nextvalue == 2) {text.probe.left.hposition = values.rechts; values.pos = values.rechts; text.probe.left.insertitem("F", 1)}
                  else if (list.posi.probe.neg.left.nextvalue == 3) {text.probe.left.hposition = values.links; values.pos = values.links; text.probe.left.insertitem("J", 1)}
                  else if (list.posi.probe.neg.left.nextvalue == 4) {text.probe.left.hposition = values.rechts; values.pos = values.rechts; text.probe.left.insertitem("J", 1)}]

Inserting an item does *not* remove any items that are already there. Since the <text> elements sample randomly without replacement, the already existing items ("A", "B") may eventually be sampled.

You don't want to use insertitem(). What you want to use is the setitem() function.
