The exact change
"Sleep is not a passive state of unconscious rest...Candidates who sacrifice sleep to study more are reducing the effectiveness of both the study and the sleep." -- Dr. Matthew Walker, Center for Human Sleep Science, University of California Berkeley | A study by Stickgold et al. (2000) demonstrated that memory performance for learning tasks completed the previous day improved by 20-30% after a full night of sleep, but not after an equivalent period of wakefulness. You literally learn more during sleep than while awake.
Sleep is not a passive state of unconscious rest...Candidates who sacrifice sleep to study more are reducing the effectiveness of both the study and the sleep. | A study by Stickgold et al. (2000) demonstrated that performance on a visual discrimination learning task completed the previous day improved after a full night of sleep, but not after an equivalent period of wakefulness. That specific finding is about visual discrimination learning rather than learning tasks in general, but it illustrates a broader pattern: sleep can improve performance on material learned the day before in ways that simply staying awake does not.
Suggested change
De-attributed the Walker quote to plain unattributed prose; corrected the Stickgold citation to accurately describe the narrow visual discrimination task actually studied rather than the fabricated generalized percentage.
Why this is better
De-attributed an unverified quote credited to Dr. Matthew Walker tailored specifically to certification exam candidates, a topic he has not written about. Corrected an unverified '20-30%' improvement figure attributed to Stickgold et al. (2000) that overgeneralized a narrow visual discrimination learning study to unspecified 'learning tasks' broadly.
