The Effects of Sleep on Cognitive Function




Examine how different amounts of sleep impact cognitive performance.


  • Cognitive function tests (e.g., memory or reaction time tests)
  • Participants
  • Notebook for recording data


  1. Group participants based on their typical sleep duration (e.g., less than 6 hours, 6-8 hours, more than 8 hours).
  2. Administer cognitive function tests to each group.
  3. Record the test results in your notebook.
  4. Compare cognitive function across the different sleep groups.
  5. Analyze the data to determine the impact of sleep duration on cognitive performance.
  6. Present your findings in a report, discussing the importance of adequate sleep for mental performance.
