In Visual Sweeps, two successive spatial frequency sweeps (movements of bars) are played. The task is to determine whether each one swept inward or outward.
Here's how the exercise works:
A colored square will be shown on screen.
Two sweeping patterns are presented with a brief break between them
The sweep patterns are created by a series of dark bars compressing or expanding
Watch the sweeps and remember if they went inward (compressing) or outward (expanding)
Remember the order in which they appeared
Once both the sweeps have finished, identify each sweep as inward or outward.
Tip!: Respond with the keyboard. Visual Sweeps is not a timed exercise, but some people like to answer with the left and right arrow keys instead of moving the mouse. The left arrow key is used for the “inward” answer, and the right arrow key is used for the “outward” answer.
Here is what an inward sweep looks like (in slow motion):
Here is what an outward sweep looks like (in slow motion):
