Design an experiment to test whether lack of sleep has an impact on someone's ability to detect a faint signal (e.g., a faint light, a faint sound, etc.). Be sure to specify your 1) experimental hypothesis and identify your 2) independent and dependent variables, as well as your 3) experimental and control groups. 4) Identify any experimental procedures that would help to ensure the reliability of your research (e.g., operational definitions, variables to be controlled).
