How long do the experiments last?

The actual experiments last from 30 minutes to one hour, depending upon the experiment, but it takes about 30 minutes to set up the electrodes.

Is there any pain involved?

The process is painless. We will be placing a felt cap (like the one shown above) on your head. We then fill each electrode with a water-soluble gel that makes a connection with your scalp. We also place electrodes on the skin around your eyes and behind your ears to measure blink activity. The gel is easily rinsed from your hair at the end of the experiment.

Can anyone participate?

Anyone age 18-35 who is not currently taking psychoactive medications (e.g. antidepressants) is encouraged to participate.

How do I sign up to participate?

Experiment time-slots are posted at http://www.cbdr.cmu.edu/experiments

How much will I be paid for participating?

It depends on how long the experiment lasts, but we generally pay at least $10 per hour.

I signed up, but will not be able to attend. What should I do?

Email your experimenter as soon as possible. Participants who do not give notice will be unable to participate in future research.
