Hello!

I have modified the AAT-script according to my needs: 20 practice trials (grey rectangles) followed by 160 „real“ trials. The real trials were as followed: 2 groups of stimuli (40 food and 40-non-food stimuli) x 2 formats (once in portrait and once in landscape format) = 160. Now I would like to pretest the script with the test monkey, but I get the following error:

trial.selectnumber: expression ' - ' is invalid. Expression contains an unknown element or property name. I think this error must be in the sequencegenerator-script as it contains this element. I have attached both scripts. What did I do wrong?

Thank you for your help!

#1:
<include>

in your AAT_neu2.iqx file

needs to read

In your aat_sequencegenerator_neu2.iqx file, your mistake is here:

<trial selectnumber>

It ought to read

<trial selectnumber>
/ ontrialbegin = [values.newnumber = list.stimcats.nextvalue]
/ ontrialbegin = [values.index += 1]
/ ontrialbegin = [
            if (values.newnumber == 1)
                        {values.runcount_1 += 1;
                        values.runcount_A += 1;
                        values.count_comparecat = values.runcount_1;
                        values.count_compareformat = values.runcount_A;
                        values.count1 -=1}
            else if (values.newnumber ==2)
                        {values.runcount_1 += 1;
                        values.runcount_B += 1;
                        values.count_comparecat = values.runcount_1;
                        values.count_compareformat = values.runcount_B;
                        values.count2 -=1}
            else if (values.newnumber ==3)
                        {values.runcount_2 += 1;
                        values.runcount_A += 1;
                        values.count_comparecat = values.runcount_2;
                        values.count_compareformat = values.runcount_A;

Thank you very much!
Now the script is working but there is another problem which occurs in some trials (not in all trials). When a picture is presented and the participant has to move the joystick, all of a sudden a second picture is presented in the same trial. This is weird because it never happened before. I have attached the raw data.
Thank you for your help!

If you look at your data file, there is clearly something wrong with your AAT_4 trial. That's where you should look for any errors / mistakes:

Yes, that's true, thank you. Also, it seems that only the low-caloric pictures in the portrait format are causing issues.
I have done the AAT again. As soon as a low-caloric_P picture is presented and I move the joystick, a new picture (all formats / categories) appears.
I have carefully checked the syntax but I haven't found any irregularities in trial / category 4. Could you please help me out? I have attached the syntax.
Thank you very much!
