display error message once mouse movement stops for 200ms

peter.k.p — Mon, 26 Oct 2020 14:28:42 GMT

Hi there,
I want to display an error message when the mouse movement stops for 200ms in a trial (see for what I tried below which does not work yet). I also want to add a /timeout for 4000ms. Is there a way to specify both within one trial? Thanks for all suggestions, I appreciate it.

[code]<trial ydecrease>
/ ontrialbegin = [
       values.errortype = 2
        values.starttime = script.elapsedtime;
]
/ inputdevice = mouse
/ stimulusframes = [1 = clearscreen, left, right, stim_left, default_stim_right]
/ timeout = 200
/ validresponse = (mousemove,noresponse)
/ responsetrial = ("noresponse", trial.error) // if there is no mouse movement for 200ms show error message
/ ontrialend = [
    values.mouse_change = abs(values.mouse_y - trial.ydecrease.responsey);
]
/ branch = [
    if (expressions.ismouseinrectangle) {
        return trial.clickresponse;
        values.mouse_y = trial.ydecrease.responsey;
    } else if (trial.ydecrease.responsey <= values.mouse_y) {
        values.mouse_y = trial.ydecrease.responsey;
        return trial.ydecrease;
    } else if (trial.ydecrease.responsey > values.mouse_y) {
        values.changedirection += 1;
        values.errortype = 1;
        return trial.error;}
]
/recorddata = true
</trial>

        else if(values.errortype == 3)
        trial.error.insertstimulustime(text.error_no_click, 0)

You'll want to do something like this:

<values>
/ starttime = 0
/ mouse_y = 0
/ errortype = 0
/ mouse_change = 0
/ finalresponse = ""
/ changedirection = 0
/ timeremaining = 0
/ trialcount = 0
</values>

<expressions>
/ set_timeout = if (values.timeremaining >= 200) {
        200;
    } else {
        values.timeremaining;
    };
/ ismouseinrectangle = ((trial.ydecrease.responsey <= shape.left.bottom)
        && (trial.ydecrease.responsey >= shape.left.top)
        && (trial.ydecrease.responsex <= shape.left.right)
        && (trial.ydecrease.responsex >= shape.left.left)

        || (trial.ydecrease.responsey <= shape.right.bottom)
        && (trial.ydecrease.responsey >= shape.right.top)
