• Then retested participants and results indicated that students in the
sleep group forgot LESS material than students in the awake group
o Why does going to sleep enhance memory
▪ eliminates environmental stimuli that might interfere with consolidation
▪ this is also enhanced during sleep
o Evidence that some memories are more likely to be consolidated than others
▪ demonstrated by Wilhelm
▪ Subjects learned a task and were later tested on the same task or a different
oe later after a ight’s sleep
