The Effect of Sleep on Face Recognition Memory - 561 Words

The Effect Of Sleep On Face Recognition Memory Sleep serves multiple purposes, ranging from restoring energy to maintaining homeostasis. Recent research has also shown that sleep plays a crucial role in memory consolidation (Scullin, 2013). There are two main types of long-term memory: explicit (declarative) memory and implicit (procedural) memory. Declarative memory is responsible for learning facts, events, and memories that can be consciously recalled, whereas procedural memory is the unconscious memory of motor skills and how to perform tasks. Several studies primarily in adults demonstrated that sleep improves procedural memory as well as declarative memory (Ellenbogen, et al., 2006). Declarative memory is important in school, work, and social settings. Early sleep and memory studies showed evidence that NonREM sleep improves performance on declarative memory tasks, such as recall and recognition. Decline in declarative memory consolidation is correlated with a decline in slow-w ave sleep. However, the effect of sleep on face recognition memory, a type of declarative memory, is relatively unstudied. Little do people know about how sleep affects memory for faces. The ability to recognize face is critically dependent on the medial temporal lobe of the brain (Squire, 2004). Learning and remembering new faces is a common, efficient, and socially important ability. Face recognition is almost indispensable in nearly all social interactions.
