Reminder Mid-course feedback form Final Exam options

Lab 5 – Sleep Deprivation “Sleep is required for memory consolidation - the process by which experience or training is transformed into improvements in performance.”

Visual Discrimination Tasks

Stickgold, James, Hobson (2000) Investigated whether you can make up for a missed night’s sleep 60-90 minute training sessoin Group A: Sleep deprived one night, unrestricted sleep 2 nights Group B: Unrestricted sleep all 3 nights Retested after 72 hours

Statistical Significance Before we mixed up the blue and green cards and counted the number of successes randomly assigned to group A Now Assume everyone would get same score regardless of which treatment they received (null hypothesis) Put numerical score on each card Mix them up and deal them out (to represent the random chance in random assignment) See how often we observed a difference in means at least as large as the actual study
