Document Summary
Trace decay theory: each rehearsal strengthens memory trace, trace decays over time, jenkins & dallenback (1924, they would show a list, wait an interval, and then ask for recall. There were different activities during this interval, too: one group went on with daily activities, the others went to sleep, performance dropped the longer the interval. The sleep condition did better than the awake condition, even though the same interval occurred: sleep consolidates memory. But the reason they looked at was interference. The group that was awake was doing/learning other things, and this information interfered with the consolidation of the items they were supposed to learn: shows that not just decay! X-axis is the number of trials on the second list they"ve already learned the first. Y-axis is the worst you"ve done on the first list. The more exposure, the worse you do on the first list.
