This study will involve one 2-3 hr session during which we will record your brain waves (EEG) while you perform a computer task. You may also be asked to complete questionnaires designed to assess your beliefs, knowledge, or abilities using paper and pencil. You will be paid $10 an hour for your participation. To be eligible, you will need to be between 18-30 years of age and have no history of neurological disorders. In addition, you must have normal or corrected-to normal vision in order to participate. Finally, we cannot perform EEG on participants with open head wounds, dreadlocks, cornrows, or braids that cannot be removed due to recording restraints.
