Current research is revealing new relationships between sleep and memory formation. Discuss prior views and current research regarding the role of sleep. How might this apply to your own preparation for exams?
What will be an ideal response?
ANSWER:
Initially, many psychologists believed that the positive role of sleep in memory formation resulted from a lack of interference. If you learned something right before going to sleep, no further information would enter the system to cause interference. More sophisticated research, however, has demonstrated that sleep plays an active role in the consolidation of memories. Changes related to memory that occur in the brain during sleep might be different than the changes that occur when we learn something while awake. Wakeful learning might serve to strengthen new connections, but sleep-related processing might reorganize existing memories to accommodate new information.

Most types of memories appear stronger after a period of sleep. We can also say with confidence that students who pull all-nighters are not doing their memory systems a favor. In one experiment, staying up all night produced poor memory for a previous task, and two additional nights of adequate sleep did not compensate for the original deprivation.
