Identifying Correlates of Cognitive Control: A Pilot Study


The University of Florida Neurocognitive Laboratory is recruiting healthy adults for a study on cognitive function. The purpose of this research study is to provide preliminary data about age differences in behavior and brain activity during cognitive tasks.


  • Be between ages 25-40 OR 55-80
  • Be in good physical health
  • Have at least 12 years of education


  • You will be asked to provide demographic information to ensure that you are eligible. This questionnaire asks you to provide your age, education, and general health status. You will also be asked about your recent alcohol use. 
  • To be sure that you can see the tasks, your vision will be checked using a reading chart
  • If you qualify for continued study, a cap (similar to a swimmer’s cap) will be placed on your head to allow measurement of your brain activity while you complete the tasks.
  • Inserted into the cap are a number of discs that are filled with a salty gel and attached by cables to a machine called and electroencephalograph (EEG), which measures electrical activity from your scalp.
  • During these tasks, your eye movements will be monitored.

Completion of the demographic and health information will take approximately 15 minutes. Completing the study tasks will take approximately 1.5 hours for a total of about 2 hours.
