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.

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. It was always a very bright color.
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 how the amount of time the unexpected object is on screen affects your likelihood of noticing it, and whether your memory for the object's characteristics, like its shape, color, and location, is affected by how long the object is onscreen.
