Instructions
Perceptual Decision Task
You will see a cloud of moving dots.
Some of the dots randomly jump around, but a portion of them are moving together either to the LEFT or to the RIGHT.
Your task is to determine the main direction of the moving wind or flow as quickly and accurately as possible.
- Sometimes it will be very obvious.
- Other times it will be very difficult to tell. Trust your gut.
