Spinning-Dancer Visual Perception

Write-down (or type) answers to the following questions, here, in class:

• Initially, does the dancer appear to be spinning clockwise, or counterclockwise?

• On average, about how many rotations occur before the spin changes directions?

• Does it more-often appear to spin clockwise, or counterclockwise?

• Does the direction change when you blink your eyes?

• Does the direction change when you move closer or farther away from the image?

• Do particular thoughts cause the direction to change? (If so, which thoughts?)

• Can you make the direction change (or stay the same) just by willing it to change (or stay the same)?

• Is there anything else you're able to do to make the direction change?

• Are you left-handed?

• Discuss and compare all of your answers with those of at least two of your classmates. Take notes on your discussion.
