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

You will watch a series of animations. Some of them are simple actions and others are dynamic, abstract patterns.

Each video will be played twice and you need to judge if the second play has a pause.

Click Next to continue.

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

When the video disappears, a "mask" image will appear to cover up the video.

Then the video will be played again, but this time, there may be a pause somewhere in the video.

Your job is to judge whether there is a pause in the second play.

You need to press F if the second play is exactly same as the first play (no pause).

You need to press J if you observe a pause in the second play.

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 pause could be very brief and in any place of the video.

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

(The study will take about 35 minutes. When the experiment is done, you will be redirected back to Prolific's webpage where you will be given a completion code.)
