The harmful effects of sleep deprivation (SD) have been well documented. In terms of cognition, SD can result in slowed response and a worse performance in cognitive tasks (Kerkhof, G & Van Dongen, 2010). However, the effects of sleep deprivation are actually less straightforward than originally believed, not all cognitive functions are affected to the same degree (Kerkhof, G & Van Dongen, 2010). For example, more complex tasks are less affected by SD, possible because they’re more engaging for participants who will put more effort into the task but despite this, decision making can still be affected (Harrison & Horne, 2000). Sleep-deprived individuals also report higher rates of physical complaints, anxiety, depression, and paranoia (Kathe-Greene, Killgore, Kamimori, Balkin, & Killgore, 2007).
