Says Robert Stickgold, a cognitive neuroscientist at Harvard Medical School: "We were basically naive about memory...
...that changed once scientists knew which kind of memory to study. Over the past couple of years, Stickgold has teamed up with Matthew Walker at Boston's Beth Israel Deaconess Medical Center to investigate sleep's effects on procedural memory for motor skills. They asked right-handed test subjects to type a sequence of numbers (for example, 4-1-3-2-4) with their left hand over and over again as fast as they could. No matter what time of day they learned the task, their accuracy improved 60% to 70% after six minutes of practice. When subjects who learned...

Both Ducey and Stickgold empathize to a certain degree with the sweat-drenched sheets of academic nightmares, but they say at a place like Harvard it’s pretty much par for the course. “Anyone who takes exams as seriously as those who care about grades and evaluations do will be plagued by such academic anxiety dreams,” Ducey says...
