Thank you very much Dave!

Just as in the incentive and nonincentive trials,

<trial baseline>
/ ontrialbegin = [
    values.delayduration = list.delay.nextvalue;
    trial.baseline.insertstimulustime(shape.target, values.delayduration);
]
/ validresponse = (values.responsekey)
/ beginresponsetime = values.delayduration
/ ontrialend = [
    trial.baseline.resetstimulusframes();
    list.baselineRT.insertitem(trial.baseline.latency, 1);
]
</trial>

is NOT valid Inquisit 4 syntax. This, then, analogously to the changes in <trial incentive> and <trial nonincentive> ought to read
mo
<trial baseline>
/ ontrialbegin = [
    values.delayduration = list.delay.nextvalue;
    trial.baseline.insertstimulustime(shape.target, values.delayduration);
]
/ isvalidresponse =  [trial.baseline.response == values.responsekey]
/ beginresponsetime = values.delayduration
/ ontrialend = [
    trial.baseline.resetstimulusframes();
    list.baselineRT.insertitem(trial.baseline.latency, 1);
]
</trial>

The iqx file is attached below.

Thank you so much Dave, it worked!! But, now the response key (when I press the spacebar after square) it doesn't move on, it doesn't accept the response. I don't know why..I think the problem is below, not sure. I tried but couldn't fix it. I actually want participants to click on mouse (both sides clicks) to respond while they are under EEG.. Is that possible to modify the response??

Thanks in advance

Özge.


<expressions>
/buttoninstruct1 = if (values.responsekey){"SPACE response button which will be located at the bottom of your screen";} else {"<SPACEBAR>";}
/buttoninstruct2 = if (values.responsekey){"response button";} else {"<SPACEBAR>";}
</expressions>

You have not defined any of the values your expressions element expects. You need to do that, i.e. add those to the script's existing <values> element or define an additional one.

<values>
/countcorrect_IncentiveReward = 0
/count_IncentiveReward = 0
/countcorrect_NonIncentiveReward = 0
/count_NonIncentiveReward = 0
/countcorrect_IncentivePunishmnet = 0
/count_IncentivePunishment = 0
/countcorrect_NonIncentivePunishment = 0
/count_NonIncentivePunishment = 0
/countcorrect_IncentiveControl = 0
/count_IncentiveControl = 0
/countcorrect_NonIncentiveControl = 0
/count_NonIncentiveControl = 0
</values>

And then, of course, you need to actually make sure those values get updated per your <trial>'s /ontrialend logic. Otherwise they won't do anything useful. I.e.

<trial incentive>
...
/ ontrialend = [
    trial.incentive.resetstimulusframes();
    values.iti = values.trialduration - values.cueduration - values.delayduration - trial.incentive.latency - values.feedbackduration;
    if (values.exp_condition == 0) {
        values.count_IncentiveControl += 1;
        values.countcorrect_IncentiveControl += trial.incentive.correct;
        list.successIncentive_Control.insertitem(trial.incentive.correct, 1);
    } else if (values.exp_condition == 1) {
        values.count_IncentiveReward += 1;
        values.countcorrect_IncentiveReward += trial.incentive.correct;
        list.successIncentive_Reward.insertitem(trial.incentive.correct, 1);
    } else if (values.exp_condition == 2) {
        values.count_IncentivePunishment += 1;
        values.countcorrect_IncentivePunishmnet += trial.incentive.correct;
        list.successIncentive_Punishment.insertitem(trial.incentive.correct, 1);
    } ;
]       
/ branch = [trial.feedback]
</trial>

Analogously for <trial nonincentive>, i.e. update the *nonincentive* count and correct count values there.

Then:

<trial incentive>
...
/ response = timeout(values.targetduration)
/ validresponse = (values.responsekey)
/ correctresponse = (values.responsekey)
...
</trial>

is not valid Inquisit 4 syntax and needs to read

<trial incentive>
...
/ timeout = values.cueduration + values.delayduration + values.targetduration
/ isvalidresponse = [trial.incentive.response == values.responsekey]
/ iscorrectresponse = [trial.incentive.response == values.responsekey]
...
</trial>

instead. Again, you need to change <trial nonincentive> analogously.
