Can I force a response?

Experimenter1 — Fri, 14 Sep 2018 06:47:07 GMT

Hello, I am trying to create multiple choice items and force a response in each item. Please note that I am not using the default radiobuttons element because I am trying to capture detailed interaction data (time-logged clicks) which I believe is not available with the default radiobuttons element.

Please see below for my code. The item allows moving on to the next without selecting any of the options. If anyone has any suggestions on how to force a response, I would greatly appreciate.
Just to be clear, all I want is to let the screen stay when a participant clicks Submit button without making a selection. I don't have to show any error message.

Thank you so much!

Yes, you can force a response by making the "submit" response invalid for the 1st instance of the trial per /isvalidresponse:

<block myblock>
/ trials = [1=MC1, clearscreen]
</block>

<values>
/ mc1count = 0
</values>

<trial MC1>
/ ontrialbegin = [
    values.mc1count += 1;
]
/ stimulusframes = [1=prompt1,option01_1,option02_1,option03_1,option04_1,option05_1,option06_1,submit]
/ inputdevice = mouse
/ validresponse = (option01_1,option02_1,option03_1,option04_1,option05_1,option06_1, submit)
/ isvalidresponse = [
    (trial.MC1.response == "submit" && values.mc1count > 1) ||
    trial.MC1.response == "option01_1" ||
    trial.MC1.response == "option02_1" ||
    trial.MC1.response == "option03_1" ||
    trial.MC1.response == "option04_1" ||
    trial.MC1.response == "option05_1" ||
