Thank you!

The only thing you can do is force the monkey to always respond correctly per /monkeyresponse:

<trial practicetrial_A>
/ ontrialbegin = [
values.targetformat = "l";
values.selectpracticepicture = 1;
values.starttime = script.elapsedtime;
values.endtime = 0;
picture.practicetarget.height = values.startheight_A;
values.completeRT = 0;
values.changedirection = 0;
values.finalresponse="";
]
/ stimulusframes = [1 = practicetarget]
/ validresponse = (back, forward)
/ iscorrectresponse = [(values.expcondition == 1 && trial.practicetrial_A.response == "forward") ||
(values.expcondition == 2 && trial.practicetrial_A.response == "back")]
/ errormessage = true(error,0)
/ response = correct
/ monkeyresponse = [
if (values.expcondition == 1) "forward" else "back"
]
/ ontrialend = [
values.joystick_y = joystick.y;
values.joystick_change = abs(values.joystick_y);
values.trialcode = "practicetrial_A";
values.RT = trial.practicetrial_A.latency;
values.correct = trial.practicetrial_A.correct;
values.stimulus = picture.practicetarget.currentitem;
if (trial.practicetrial_A.response == "forward")
values.initialresponse = "PUSH"
else
values.initialresponse = "PULL";
]
/ branch = [
if (trial.practicetrial_A.response == "forward")
trial.practicedecrease
else
trial.practiceincrease;
]
/ recorddata = false
</trial>


NOTE:
trial.practicetrial_B displays the stimulus of format B (here: portrait) by setting
values.selectpracticepicture = 2
*if a forward movement (=push) is detected -> decrease picture
*if a back movement (=pull) is detected -> increase picture


<trial practicetrial_B>
/ ontrialbegin = [
values.targetformat = "p";
values.starttime = script.elapsedtime;
values.endtime = 0;
values.repeat = 0;
values.selectpracticepicture = 2;
picture.practicetarget.height = values.startheight_B;
values.completeRT = 0;
values.changedirection = 0;
values.finalresponse="";
]
/ stimulusframes = [1 = practicetarget]
/ validresponse = (back, forward)
/ iscorrectresponse = [(values.expcondition == 1 && trial.practicetrial_B.response == "back") ||
(values.expcondition == 2 && trial.practicetrial_B.response == "forward")]
/ errormessage = true(error,0)
/ response = correct
/ monkeyresponse = [
if (values.expcondition == 1) "back" else "forward"
]

values.joystick_y = joystick.y;
values.joystick_change = abs(values.joystick_y);
values.trialcode = "practicetrial_B";
values.RT = trial.practicetrial_B.latency;
values.correct = trial.practicetrial_B.correct;
values.stimulus = picture.practicetarget.currentitem;
if (trial.practicetrial_B.response == "forward")
values.initialresponse = "PUSH"
else
values.initialresponse = "PULL";
]
/ branch = [
if (trial.practicetrial_B.response == "forward")
trial.practicedecrease
else
trial.practiceincrease;
]
/ recorddata = false
</trial>

};
picture.practicetarget.height = picture.practicetarget.height - values.joystick_change/1000 * expressions.maxheightchange_px;

Thank you very much! This was helpful. I'll rephrase my second question - I would like participants to correct their errors by moving the joystick in the correct direction once told it is an error. I am able to do this no problem because I have added "/response = correct" which requires participants to correct their prior erroneous response. However, when I try to test out my script in monkeymode, it gets stuck on the screen saying "error" and does not correct the response, and will not finish running the script. I am not sure how to code a new response for monkeymode. Thank you!


/ errormessage = true(error,0)
/ response = correct

I've attached an AAT script with error messages in the test trials, so you can take a look at that. I don't understand your second question.

One other question I have is that during practice trials, I have added "response = correct" so that participants have to correctly pull or push the joystick to advance. However, I am now not able to run monkeymode when an error is encountered - the screen stays as is with "ERROR" on screen and does not advance. Thank you!
