I will be checking the computer specifications once I get to the campus on Monday December 1st).
I looked at the PLATO Visual Occlusion Spectacles. They seem promising, but the price is very steep (we need to accommodate multiple participants at once, so we would need multiple goggles).
I figure I would use a 120 HZ monitor. They are more affordable and can expose people to stimuli at around 8 ms.
You have been extremely helpful.
Thank you again,
Patrick M.
