You can set this parameter to `false` to force the participant to listen to the stimulus for a fixed amount of time, even if they respond before the time is complete. |

If false, then the audio must finish playing before the slider is enabled and the trial can end via the next button click.

This prevents a blank screen (white flash) between consecutive image trials in some browsers, like Firefox and Edge. If false, the image will be shown via an img element, as in previous versions of jsPsych. If the stimulus is an **animated gif**, you must set this parameter to false, because the canvas rendering method will only present static images.
