Please click and drag the cross to the place on the display where you first noticed a new object appear.
If you didn't see the new object, drag the shape to where you think it might have appeared.
Please close as many browser tabs as possible to ensure the task runs smoothly.
In this task, you will see four white shapes and four black shapes. These shapes will move and bounce around inside a blue rectangle. These shapes will randomly speed up and slow down while they move.
Try to keep your eyes fixed on the dark blue square while you complete this task. You will complete three brief trials.

Purpose of the Study
In this study, you performed a demanding multiple object tracking task. In the third trial, a new, unexpected object passed through the display.
Depending on which experimental condition you were in, the unexpected object was visible for a long time or only briefly.
When people are engaged in a difficult task like the one you performed, they often don't notice the new object when it passes through the display.
We're trying to learn more about why this happens, and part of that is exploring how often the new object is noticed depending on how long it is
visible in the display.
