Dr. Kushner is especially curious about selective sleep deprivation, where people are kept from entering REM (rapid eye movement) sleep. Using an electroencephalograph (EEG) to monitor brain waves, he plans to let participants sleep until they enter REM sleep and then wake them.

He plans to do this through the entire eight-hour sleep session. The following morning, participants will be asked to take a sample SAT test.
