This study tests your ability to perceive the continuity of videos.

You will watch a series of animations.

Some videos will be played smoothly, but other videos will contain a small glitch (which looks like the video freezing for a very brief moment).

Click Next to continue.

On each trial, you will first watch a video clip.

The video could either look fluent and normal, or have a very small glitch.

Your job is to judge whether there is a glitch in the video.

You need to press F if you observe a glitch in the video.

You need to press J if the video is going smoothly without any glitches.

The container's border will turn to green if your response is correct, red if incorrect.

To start off, you'll do a couple of practice trials.

Click "Start Practice" to begin.

You have done the practice! In the next trials, the glitch could be very brief and in any place of the video.

You need to pay close attention to the videos to detect those glitches! The task is not easy, but please try your best!

The study will take about 17 minutes. There will be periodic breaks interspersed throughout the study.

When the experiment is done, you will be redirected back to Prolific's webpage where you will be given a completion code.
