The Sleep and Cognition Laboratory (SCL), formerly called the Cognitive Neuroscience Laboratory is a multidisciplinary research team that is dedicated to improving human cognitive performance, health and wellbeing through is research on the benefits of sleep on cognition and conversely the neurobehavioral effects of sleep loss or fragmentation. Alongside, we seek to better understand how sleep can be optimized to improve cognitive aging.

We compared habitual and non-habitual nappers and their performance on a range of memory tasks following either a nap or wake period. It was found that naps were especially beneficial for habitual nappers performing a short-term topographical memory task, however napping was overall beneficial for long-term memory tasks even if one did not habitually nap.
