Using mouse track with dashed sentence

[Igor Costa]

Hi, Jeremy

I’m having some issues in coding an experiment in PCIbex. In short, I need an experiment in which the presentation sequence for each trial is as below:

1. two images are printed in the screen and stay there;
2. two seconds later, a self-paced reading sentence appears;
3. simultaneously with the start of the sentence, the possibility to click on one of the images starts;
4. when the participant clicks on a image, the trial ends, even if the participant did not finish the dashed sentence.

What I want is, for instance, if there are two images of warning board, one of which is blank and another contais a message, that the participant could, when he/she sees “not empty” in the sentence, be able to click at the correct image.

I could code the first three steps, but I could not figure out how to implement the forth one. My code is below.

newTrial("frase_1",
    newImage("a1", "aviso1.png")
        .size(200,200)
    ,

    newImage("a2", "aviso3.png")
        .size(200,200)
    ,

      newMouseTracker("mouse")
        .log()
        .start()
    ,

    newCanvas("canvas_esq", "40vw", "40vh")
        .add(250, 10, getImage("a1"))
        .print("center at 25vw", "middle at 50vh")
    ,

    newCanvas("canvas_dir","40vw", "40vh")
        .add(50, 10, getImage("a2"))
        .print("center at 75vw", "middle at 50vh")
    ,

    newTimer("pausa", 2000)
    .start()
    .wait()
    ,

    newSelector("escolha")
        .add(getCanvas("canvas_esq"), getCanvas("canvas_dir"))
        .log()
    ,

    newController("DashedSentence", {s: "This is not an empty warning."})
        .center()
        .print()
        .log()
        .wait()
        .remove()
    ,

    getMouseTracker("mouse")
        .stop()
    )

I think I might have misunderstood the .wait() element for the newController.

Thanks in advance for any help.

Hi,

Have you tried doing something like this:

PennController.ResetPrefix(null);

newTrial("frase_1",
    newImage("a1", "aviso1.png")
        .size(200,200)
    ,

    newImage("a2", "aviso3.png")
        .size(200,200)
    ,

      newMouseTracker("mouse")
        .log()
        .start()
    ,

    newCanvas("canvas_esq", "40vw", "40vh")
        .add(250, 10, getImage("a1"))
        .print("center at 25vw", "middle at 50vh")
    ,

    newCanvas("canvas_dir","40vw", "40vh")
        .add(50, 10, getImage("a2"))
        .print("center at 75vw", "middle at 50vh")
    ,

    newTimer("pausa", 2000)
    .start()
    .wait()
    ,

    newController("DashedSentence", {s: "This is not an empty warning."})
        .center()
        .print()
        .log()
    ,
    newSelector("escolha")
        .add(getCanvas("canvas_esq"), getCanvas("canvas_dir"))
        .wait()
        .log()
    ,
    getMouseTracker("mouse")
        .stop()
    )

Hope it helps!

Thank you, Amilam!!!

It was exactly what I was looking for and I could not thinking about putting the .wait() element just after the .newSelector().

Thank you for your help!
