Instructions
Signal Detection Task
You will see a square patch of visual static or noise, like an untuned television.
On some trials, a very faint Target Circle will be hidden in the center of the noise. On other trials, it is just pure noise.
Your task is to detect whether the target signal was PRESENT or ABSENT.
Example: the target at high visibility.
