How to play and repeat stimuli after manual click?

Coding
1

Hi,

in my current code there is a sequence of sound stimuli (2 in this example) which are randomized.
Each stimulus has to be rated from 1 to 5, and after each rating the next stimulus starts playing automatically and is played just for one time.

What I would like to implement now is:
- a PLAY button which allows to start playing the sound ony when the participant likes, so no more automatic starting;
- the play button can be pressed as many times as one likes, so many repetitions are allowed;

  • as now, after evaluation on the rating scale + confirmation by clicking inside the white box below the ratingscale, the experiment continues with the following stimulus;
  • as now, the order of presentation of the stimuli is randomized.

I attach the code.

Many thanks,
Erica

Hi @ericabisesi, yes this is possible and in this case I have used the right mouse button to replay the sound. You could add a code component in the Builder view. In the Start Routine tab, add:

 def playSound():
    beep = sound.Sound('A', secs=.3)  # You will probably need to add your sound variable e.g. 'Sound'
    beep.setVolume(1)
    beep.play()
    core.wait(.3)

In the Every Frame tab, add the following which checks whether or not the right mouse button was clicked:

if mouse.getPressed()[2] != 0:
    playSound()  # Call your playSound function defined at the beginning of the routine

Hallo David,

thanks for having considered my request.

  1. The error is:

if mouse.getPressed()[2] != 0:
NameError: name ā€˜mouseā€™ is not defined

How can I define the ā€œmouseā€?

  1. There is a sentence (by you) I donā€™t understand:
 You will probably need to add your sound variable e.g. 'Sound'

What should I do there?

  1. I attach 3 screenshots to check for compatibility with previous statements in the routines after adding the code.

Thanks, see you soon.

Erica

Apologies, I had interpretted ā€œpush a buttonā€ as a mouse button and has assumed you were using a mouse. You could swap that code with something that checks for a key press instead. See the Keyboard API here.

For ā€˜Soundā€™, you have a variable in your code called ā€˜Soundā€™, which I believe will be a column in your datafile, which should be a list of your sound files. So, rather than setting sound to an ā€˜Aā€™ note in the function called playSound, you will want to set your sound to the sound variable holding your sound file name that is to be played.

Yes your code looks fine, although you will want to replace the conditional that relies on a mouse click to something else, as above.

I donā€™t understandā€¦

I connected a mouse and this does not fix the problem, can you say me why? Just to understandā€¦

Then I looked at other options as you suggestedā€¦ Anyway I am wondering why it wouldnā€™t be easier to define the ā€˜mouseā€™.

Maybe I explained badly. With ā€œpush a buttonā€ I meant that an interactive option will appear on the screen with a PLAY indicator (like the little arrow on youtube).

This would be optiomal.

But also the spacebar can work, or any other key.

In this second case I kindly ask to tell me ho w to codeā€¦ I see also the picture of a keyboard in the Components Menu, maybe something from there? But I donā€™t understand how to link to the rest.

Ok, well if you add a mouse component to the relevant routine in Builder, and call it ā€˜mouseā€™ (which is the default name) - it should work. Although, you will need to make sure that the mouse is not set up to end the routine on any click, else your trial will end without the option of repeats.

If you want to use a shape on screen, you need to make sure that you are using a version of psychopy that supports the use of the isPressedIn function - see here. You would then use this function like this, in the ā€˜Each Frameā€™ tab of your code component:

if mouse.isPressedIn(<Name of your shape>, buttons=0):
    playSound()

Alternatively, use a keyboard and add the following to the coder in the ā€˜Each Frameā€™:

if event.getKeys(keyList=["space"]):
    playSound()

This will allow you to use the spacebar to repeat trials :slight_smile:

Hi @dvbridges,
Thanks for your suggestion. This was really helpful. While I was able to make it work in the local PsychoPy experiment, this does not work online. I think the problem is due to the function you created, playsound, is not defined in Javascript. I was wondering if you could help translating the python code below into Javascript.

def playSound():
    beep = sound.Sound('A', secs=.3)  # You will probably need to add your sound variable e.g. 'Sound'
    beep.setVolume(1)
    beep.play()
    core.wait(.3)

Thank you!

Hi @HungShao, you could try:

playSound = function() {
  beep = new Sound({
    win: psychoJS.window,
    value: "A",
    secs: .3,
  });
  beep.setVolume(1);
  beep.play()
}

Hi @dvbridges.

thank you! I put the code into the experiment and change ā€œAā€ to the variable, sounds. However, this error came up when I right click the mouse.

This is the code I have
Begin Routine

modify = false;
text.text = "";

playSound = function() {
  beep = new Sound({
    win: psychoJS.window,
    value: sounds,
    secs: .3,
  });
  beep.setVolume(1);
  beep.play()
}

Each frame

let theseKeys = psychoJS.eventManager.getKeys();
if (theseKeys.length > 0) {  // at least one key was pressed
  textAdd = theseKeys[theseKeys.length-1]; 
  }


if (textAdd === 'return') {
    textAdd = '';  // Add nothing
    continueRoutine = false;  // End routine (if that is what you want)
} else if (textAdd === 'space') {
    textAdd = ' ';  // Add a space
} else if (textAdd === 'backspace') {
    text.text = text.text.slice(0, -1);
    textAdd = undefined;
} else if (['lshift', 'rshift'].includes(textAdd)) {
    modify = true;
} else if (textAdd !== undefined) {
    if (modify) {
        text.text = text.text + textAdd.toUpperCase();
        modify = false;
    } else {
        text.text = text.text + textAdd
    }
    textAdd = undefined;
}

if ((mouse.getPressed()[2] !== 0)) {
    playSound();
}

I am guessing this error is due to the found file canā€™t be found? But i am not so sure, do you know what the errors might be here and any solutions?

Thanks again! Really appreciate your help.

Hi @dvbridges,

I tried to modify your code a little bit (not sure if it is the right move) and I was able to get the sound to play after right-clicking the mouse. However, the sound is very distorted and it also affect the quality of any subsequent sounds. Is Each Frame not the right place to add the code? Here is the modification as well as the URL of the experiment

Begin Routine

modify = false;
text.text = '';

beep = new sound.Sound({
    win: psychoJS.window,
    value: sounds,
    secs: 3,
  });

Each Frame

let theseKeys = psychoJS.eventManager.getKeys();
if (theseKeys.length > 0) {  // at least one key was pressed
  textAdd = theseKeys[theseKeys.length-1]; 
  }


if (textAdd === 'return') {
    textAdd = '';  // Add nothing
    continueRoutine = false;  // End routine (if that is what you want)
} else if (textAdd === 'space') {
    textAdd = ' ';  // Add a space
} else if (textAdd === 'backspace') {
    text.text = text.text.slice(0, -1);
    textAdd = undefined;
} else if (['lshift', 'rshift'].includes(textAdd)) {
    modify = true;
} else if (textAdd !== undefined) {
    if (modify) {
        text.text = text.text + textAdd.toUpperCase();
        modify = false;
    } else {
        text.text = text.text + textAdd
    }
    textAdd = undefined;
}


if ((mouse.getPressed()[2] !== 0)) {
    beep.play();
}

@HungShao, yes in this instance this is happening because mouse.getPressed() records when a mouse button is clicked, not the current state of the mouse. So, after clicking the right mouse button, the play condition is always true and then the sound is continually played. An easy fix is to reset the mouse button after each right mouse button click. This is not necessarily the recommended way, however I do not see any other working method for resetting mouse clicks online:

if ((mouse.getPressed()[2] !== 0)) {
    beep.play();
    psychoJS.eventManager.getMouseInfo().buttons.pressed = [0,0,0]
}

@dvbridges
Thank you so much!! This fixed the issue. One tiny follow-up, is it possible to switch from right-click to left-click?

Really appreciate your help!

Hi I figured this out. Thanks so much again!
