Sleep’s effect on study

Sleep's effect on study

Students everywhere, rejoice. Scientific research seems to support the nap you just got in trouble for taking during English class.

A new study from the University of Notre Dame tested sleep’s effect on 207 students’ success in remembering declarative information – facts and events – in semantically related or unrelated word pairs. Students learned at either 9 a.m. or 9 p.m., and underwent recall testing 30 minutes, 12 hours, or 24 hours later. While the time of day during which students learned showed no effect on memory initially, testing results after 12 hours were better in those who slept overnight versus those who spent the day awake. And in tests done 24 hours after learning, students who had slept immediately after learning demonstrated significantly greater recall of the unrelated word pairs.

A Notre Dame article quotes psychologist Jessica Payne, PhD, first author of the study, on its significance:

Since we found that sleeping soon after learning benefited both types of memory, this means that it would be a good thing to rehearse any information you need to remember just prior to going to bed. In some sense, you may be ‘telling’ the sleeping brain what to consolidate.

  1. Calin Coroban Says:

    Despite the therapeutic effectiveness and proven success of CBT, treatment availability is significantly limited by a lack of trained clinicians, poor geographical distribution of knowledgeable professionals, and expense. One way to potentially overcome these barriers is to use the Internet to deliver treatment, making this effective intervention more accessible and less costly. The Internet has already become a critical source of health-care and medical information.Although the vast majority of health websites provide general information,there is growing research literature on the development and evaluation of Internet interventions.These online programs are typically behaviorally-based treatments that have been operationalized and transformed for delivery via the Internet. They are usually highly structured; automated or human supported; based on effective face-to-face treatment; personalized to the user; interactive; enhanced by graphics, animations, audio, and possibly video; and tailored to provide follow-up and feedback.A number of Internet interventions for insomnia have been developed and a few of them have been evaluated as part of scientific research trials. A paper published in 2012 reviewed the related literature and found good evidence for the use of Internet interventions for insomnia. A U.S. based study, evaluating the efficacy of SHUTi (Sleep Healthy Using The Internet), is currently seeking participants to further examine the effectiveness of using the Internet to deliver cognitive behavioral therapy for insomnia (www.shuti.org). In addition to this NIH funded trial, several international trials will begin in late 2012 in Australia and Norway.
