Hi!
I've developed a response-time task in which people must choose one of two options before proceeding to the next question. Upon selecting a choice by pressing one of two buttons on their keyboard, they automatically proceed to the next question.
In addition, if they do not answer the question within 2.5 seconds, they automatically proceed to the next question.
In the latter case, I'd like to display a warning message such as, "Respond faster" People should see that message for a second or two before viewing the next item.
Can this (displaying a temporary warning message) be done?

If helpful, here is my current Javascript:
Qualtrics.SurveyEngine.addOnload(function()
{
this.hideNextButton();
this.hidePreviousButton();
var that = this;
Event.observe(document, 'keydown', function keydownCallback(e) {
var choiceID = null;
switch (e.keyCode) {
case 65: // "a"  was pressed  for chart of cases go to...  https://www.w3schools.com/charsets/ref_utf_basic_latin.asp
choiceID = 1;
break;
case 76: // "l" was pressed.
choiceID = 2;
break;
}
if (choiceID) {
Event.stopObserving(document, 'keydown', keydownCallback);
that.setChoiceValue(choiceID, true);
that.clickNextButton();
}
});
});
