Stroop Task, Random Color

DannyPilgrim — Fri, 30 Apr 2021 14:43:25 GMT

Hello everyone,

right now I am programming a Stroop-Task with different words and I would like to know whether it is possible to assign the colors (red, green, blue, yellow) in a randomized order for each participant.

Normally it would look like that:
<text rot>
/ items = ("rot")
/ color = red
</text rot>

<trial rot>
/ stimulustimes = [1=rot, redreminder, greenreminder, bluereminder, yellowreminder]
/ correctresponse = ("d")
/ validresponse = ("d" "f" "j" "k")
/ontrialend = [
    if (trial.rot.responsetext == "D"){
        values.responseCategory = "red";
    } else if (trial.rot.responsetext == "F"){
        values.responseCategory = "green";
    } else if (trial.rot.responsetext == "J"){
        values.responseCategory = "blue";
    } else if (trial.rot.responsetext == "K"){
        values.responseCategory = "yellow";
    };
    list.responses.appenditem(trial.rot.correct);
    list.responses_congruent.appenditem(trial.rot.correct);
    if (trial.rot.correct) {
        list.latencies.appenditem(trial.rot.latency);
        list.latencies_congruent.appenditem(trial.rot.latency);
    }
]
</trial>

I would like to do it this way:
<text rot>
/ items = ("rot")
/ color = red, green, blue, yellow
</text rot>

<trial rot>
/ stimulustimes = [1=rot, redreminder, greenreminder, bluereminder, yellowreminder]
/ correctresponse = ("d") (Now I have the problem that I cannot specifiy the correct answer for this trial because of the randomization. What do I have to define for the result files to see which answer would have been the correct one if the participant pushed a button?)
/ validresponse = ("d" "f" "j" "k")
/ontrialend = [
if (trial.rot.responsetext == "D"){
   values.responseCategory = "red";
} else if (trial.rot.responsetext == "F"){
   values.responseCategory = "green";
} else if (trial.rot.responsetext == "J"){
   values.responseCategory = "blue";
} else if (trial.rot.responsetext == "K"){
   values.responseCategory = "yellow";
};
list.responses.appenditem(trial.rot.correct);
list.responses_congruent.appenditem(trial.rot.correct);
if (trial.rot.correct) {
   list.latencies.appenditem(trial.rot.latency);
   list.latencies_congruent.appenditem(trial.rot.latency);
}
]
</trial>

I hope you understand this issue. If additional information is required feel free to ask!

Thank you very much!

Best Regards,
Danny

You can set both the color as well as the correct response key from paired <list> elements.

Short example:

[code]<text stimulus>
/ items = ("The Stimulus Text")
</text>

<list displaycolor>
/ items = (red, green, blue, yellow)
</list>

<list correctkey>
/ items = ("D", "F", "J", "K")
/ selectionmode = list.displaycolor.currentindex
</list>

<values>
/ correctkey = " "
</values>

<block exampleblock>
/ trials = [1-4 = example]
</block>

<trial example>
/ ontrialbegin = [
    text.stimulus.textcolor = list.displaycolor.nextvalue;
    values.correctkey = list.correctkey.nextvalue;
]
/ stimulusframes = [1=stimulus]
/ validresponse = ("D", "F", "J", "K")
/ correctresponse = (values.correctkey)
/ errormessage = true(errortext, 500)
/ correctmessage = true(correcttext, 500)
</trial>

<text errortext>
/ items = ("X")
/ txcolor = red
/ position = (50%, 75%)
</text>

<text correcttext>
/ items = ("O")
/ txcolor = green
/ position = (50%, 75%)
</text>
[/code]

That helped alot again!
Thank you very much, Dave
