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.

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>

Shouldn't happen if your Inquisit installation is up to date.

Hello,

I update to 4.0.7 from 4.0.2 and the quotes disappeared. Thanks a lot.

Jens

Please note that the current release is 4.0.8.0, available (as always) via

Hello Dave,

I will inform our IT about the new release.

Hello,

the evaluation no longer works.

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

/iscorrectresponse = [if (text.probe.right.currentitem == "F"){values.korrekt = 36} else {values.korrekt = 33}] always evaluates to 1 but it should evaluate to 0 in row 2 or row 4 of the data file (or the assignment of values.korrekt is incorrect).

Jens,

/iscorrectresponse = [if (text.probe.right.currentitem == "F"){values.korrekt = 36} else {values.korrekt = 33}]

cannot work because you never check values.korrekt against the trial's response property.
