How to run a loop for a set of Videos and Audios in a trial?

[Mananshi]

I am currently trying to design an experiment wherein I have to present a video/audio which would be followed by a question and record participant's response via the screen or the keyboard. The participant is not required to interact with any of the media files and has to just listen to the audio or view the video and answer a simple question for which, choices would be pre-defined.

Note: Numerous Videos and Audio are to be presented randomly hence creating individual stimuli won't be feasible.

Can someone please help me out with this? I am a beginner and I am not quite aware of how to work with Video and Audio files in a trial.

Hi @Mananshi,

If you want to present a video file without interaction, then you can use the video-keyboard-response plugin and set the choices parameter to jsPsych.NO_KEYS. This will prevent the user from interacting with the trial. You can combine this with either trial_ends_after_video or trial_duration to control the timing of the end of the trial.

For audio files the process is the same, but with the audio-keyboard-response plugin.
