Frequently Asked Questions

How long do the experiments last?

The cap set-up with the gel requires about 30 minutes and then the actual experiments last an additional 30 minutes to one hour. The total time commitment is at least one hour.

Are there any risks involved?

Our EEG experiments are minimal risk and are approved by Carnegie Mellon University's Institutional Review Board.

Can anyone participate?

Anyone age 18-35 with normal to corrected vision 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 In addition, if you are a CMU student taking Psychology courses, you may also sign-up from the Psychology Department's Subject Pool.

How much will I be paid for participating?

It depends on how long the experiment lasts, but we pay at least $10 per hour. If you signed up from the Subject Pool, you will be given a credit for the first hour and paid for your time after that.

What should I do to prepare for my experiment?

Please make sure that your hair is clean and dry.

Hardware and Software

We use a Neuroscan Synamps2 system with 64 electrode Neuroscan QuikCaps. Data is collected via Neuroscan Scan software and experiments are run using E-prime.

The Faraday Cage

A faraday cage (shown above) is a cage made of a conductive material, copper in our case. It is used to keep external electrical noise from affecting the EEG brainwave readings. For more information, see:
