Hi,

I'd like to let participants know to slow down if they're responding to trials too quickly. With your help, I've been able to do this at the trial level, but I would like to actually do it at the block level instead, so that this message only appears for certain blocks. I've modified my script (see below) but for some reason nothing is happening - no error message shows up at all. Is there a better way to do this, or a way I can make this work? Thanks!

I've added this (bolded) to my block elements:

<block compatiblepractice_AFArts_WMMath>
/ bgstim = (targetBleftmixed, attributeBleft, targetArightmixed, attributeAright)
/ trials = [
    1,3,5,7,9,11,13,15,17,19= random(targetBleft, targetAright);
    2,4,6,8,10,12,14,16,18,20 = random(attributeBL, attributeAR)]
/ errormessage = true(error,200)
/ responsemode = correct
/ ontrialend = [
    if(block.compatiblepractice_AFArts_WMMath.latency <= 10000 && block.compatiblepractice_AFArts_WMMath.currenttrialnumber != 1 && script.currenttrial != "toofast") {
        values.sum1a += block.compatiblepractice_AFArts_WMMath.latency;
        values.n1a += 1;
        values.ss1a += (block.compatiblepractice_AFArts_WMMath.latency * block.compatiblepractice_AFArts_WMMath.latency);
        values.n_correct += block.compatiblepractice_AFArts_WMMath.correct;
    };
    
    if (block.compatiblepractice_AFArts_WMMath.latency < parameters.toofastlatency) {
        return trial.toofast;
    };

    if(block.compatiblepractice_AFArts_WMMath.latency < 300 && script.currenttrial != "toofast") {
        list.RT300.appenditem(1);
    } else {
        list.RT300.appenditem(0);
    };
]
</block>

and for reference, these are the other attributes called in that line:

<parameters>
/ toofastlatency = 300
/showsummaryfeedback = false
/ISI = 250
</parameters>

<trial toofast>
/ stimulusframes = [1=toofasttxt]
/ validresponse = (0)
/ trialduration = 5000
/ recorddata = false
/ posttrialpause = parameters.ISI
</trial>

<text toofasttxt>

/ontrialend attributes are not /branch attributes, so this cannot and is not supposed to work.

You must /branch at the <trial> level, but you are of course free to make that conditonal on the block that is currently running.

Extending the previous example ( https://www.millisecond.com/forums/Topic29176.aspx ) for illustration, suppose you only want the "too fast" message for the two shorter test blocks (compatibletest1 and incompatibletest1), then you would simply state

<trial attributeA>

/ stimulusframes = [1 = attributeA, errorReminder]

    }

</trial>

<trial attributeB>
/ validresponse = ("E", "I")
/ correctresponse = ("I")
/ stimulusframes = [1 = attributeB, errorReminder]
/ posttrialpause = parameters.ISI
/ branch = [
    if ((script.currentblock == "compatibletest1" || script.currentblock == "incompatibletest1") && trial.attributeB.latency < parameters.toofastlatency) {
        return trial.toofast;
    }
]
</trial>

<trial targetBleft>

        return trial.toofast;
    }
]
</trial>

<trial targetBright>
/ validresponse = ("E", "I")

/ posttrialpause = parameters.ISI
/ branch = [
    if ((script.currentblock == "compatibletest1" || script.currentblock == "incompatibletest1") && trial.targetBright.latency < parameters.toofastlatency) {

</trial>

Or, if you want to make things slightly more flexible and elegant, create a parameter determining whether the "too fast" trial should be run

<parameters>
/ showtoofast = false
....
</parameters>

and set that variable to true in the blocks where you want to show the reminder and to false in the blocks where you don't

<block attributepractice>
/ onblockbegin = [
  parameters.showtoofast = false;
]
/ bgstim = (attributeAleft, attributeBright)
/ trials = [
  1=instructions;
  2-21 = random(attributeA, attributeB);
]
/ errormessage = true(error,200)
/ responsemode = correct
</block>

...

<block compatibletest1>
/ onblockbegin = [
    parameters.showtoofast = true;
]
/ bgstim = (targetAleftmixed, orleft, attributeAleft, targetBrightmixed, orright, attributeBright)
/ trials = [
    1=instructions;
    3,5,7,9,11,13,15,17,19,21= random(targetAleft, targetBright);
    2,4,6,8,10,12,14,16,18,20 = random(attributeA, attributeB)]
/ errormessage = true(error,200)
/ responsemode = correct
/ ontrialend = [
    if (block.compatibletest1.latency <= 10000 && block.compatibletest1.currenttrialnumber != 1 && script.currenttrial != "toofast") {
        values.sum1a += block.compatibletest1.latency;
        values.n1a += 1;
        values.ss1a += (block.compatibletest1.latency * block.compatibletest1.latency);
        values.n_correct += block.compatibletest1.correct;
    };
    if (block.compatibletest1.latency < 300 && script.currenttrial != "toofast") {
        list.RT300.appenditem(1);
    } else {
        list.RT300.appenditem(0);
    };
]
</block>

...

and do

<trial attributeA>
/ validresponse = ("E", "I")
/ correctresponse = ("E")
/ stimulusframes = [1 = attributeA, errorReminder]
/ posttrialpause = parameters.ISI
/ branch = [
    if (parameters.showtoofast && trial.attributeA.latency < parameters.toofastlatency) {
        return trial.toofast;
    }
]
</trial>

at the trial-level.
