trial_ends_after_audio in psychophysics

[kittymimo]

Hi,

I am running an experiment offline and I am using the psychophysics plugin. I have audio stimuli that are playing fine, but I am unable to use the trial_ends_after_audio parameter. I came across this issue in the past with prior versions of jspsych and the psychophysics plugin, and @becky-gilbert helped me update the plugin back then (see discussion #1158). Now both jspsych and the psychophysics plugin have been updated, and I am unable to use the trial_ends_after_audio parameter again. I am using v4.1.0 of the plugin and v8.2.2 of jspsych.

Do you have any suggestions for making this work (offline)?

Thanks a lot!

Hi, @kittymimo

Thank you very much for using my plugin.

I am writing to apologize as I found a bug in the current version. I have attached the latest plugin file to this post—could you please replace your current version with this one?
jspsych-psychophysics.zip

If it works correctly on your end, I will proceed to update my repository (please note that the repository has not been updated yet).

I have included a usage example below for your reference.

    const sounds = [ 
        './sound/tone100ms.wav',
        './sound/880Hz_100ms.wav'
    ];

    // Preloading files are needed to present the stimuli accurately.
    const preload = {
        type: jsPsychPreload,
        audio: sounds,
    }

    const sound1 = {
        obj_type: 'sound',
        file: sounds[0],
        trial_ends_after_audio: true
    }

    const trial = {
        type: jsPsychPsychophysics,
        stimuli: [sound1],
        choices: ['y', 'n'], // The participant can respond to the stimuli using the 'y' or 'n' key.
        prompt: 'Press the Y or N key to respond.',
        canvas_height: 500
    }

Best regards,
Daiichiro
