Sleep & cognition research, explained
7 open-access sleep & cognition studies, each with a flashcard deck and a quiz.
- Does poor sleep make older adults forget faster over a week?
Healthy older adults forget newly learned word associations much faster over a seven-day period than younger adults, and this forgetting is linked to waking up frequently during the night.
- How Sleep Loss Affects Older Adults' Positive Focus and Memory
One night of total sleep deprivation does not impair older adults' working memory or their natural tendency to focus on positive rather than negative images.
- How Total and Partial Sleep Loss Affect Different Types of Memory
Losing sleep consistently reduces memory accuracy and leads to lapses in attention, even when the sleep restriction is only partial.
- How sleep affects item and context memory in children
Sleep helps children retain both word pairs and their context, but it does not specifically strengthen the bond linking a word pair to its original context.
- Do naps and caffeine help sleep-deprived athletes perform better?
Caffeine improves basic reaction speeds, while a short afternoon nap enhances decision-making accuracy, but combining the two offers no extra benefit.
- Can exercise help your brain recover from sleep loss?
Doing a brief session of moderate aerobic exercise can temporarily restore focus and self-control after a night of no sleep.
- Can ear nerve stimulation help sleep-deprived soldiers stay alert?
Vagus nerve stimulation via the ear can help sleep-deprived individuals maintain their attention and mood during early morning hours when sleep pressure is highest.
