Many studies have investigated factors that affect susceptibility to false memories (i.e., memory of events that never happened at all). However, few have investigated the role of sleep deprivation in the formation of false memories, despite overwhelming evidence that sleep deprivation impairs cognitive function. We examined the relationship the effect of 24 hr of total sleep deprivation on susceptibility to false memories. We found that under certain conditions, sleep deprivation can increase the risk of developing false memories. In this experiment, we deprived our participants of sleep and then either had them encode (i.e., To input or take into memory, to convert to a usable mental form, to store into memory) an event when they were actively sleep deprived or before they were sleep deprived, then tested their memory of the event. We found that sleep deprivation increased false memories in a task when participants were sleep deprived during the encoding of an event, but sleep deprivation did not have a significant effect when the deprivation occurred after event encoding. These experiments are the first to investigate the effect of sleep deprivation on susceptibility to false memories, which can have dire consequences. 6. What is the research question? 7.
