Editing Interference theory (section)

====Forgetting====
Since German psychologist H. Ebbinghaus (1885, 1913) made the first scientific studies on forgetting in the late nineteenth century, further research on the rate of forgetting presented information was found to be steep.<ref name="Edwards"/> While a variety of factors play a role in affecting the rate of forgetting, the general conclusion made is that 70% of originally recalled information is initially forgotten in 24 hours after a session of practice, followed by 80% of information forgotten within 48 hours.<ref name="Edwards"/> Afterwards, forgetting diminishes at a gradual rate, which leaves about 5% to 10% of retained information available for learners to access from practice until the next session.<ref name="Edwards"/> Despite the numbers, retroactive interference can be reduced significantly by implementing over-learning practice schedules, periodic refresh sessions when practicing skills, and skill rehearsal time for the inactive periods of practicing.<ref name="Edwards"/> Continuous skills are more resistant to the rate of forgetting compared to discrete skills, which indicates that the types of skills being practiced and retroactive interference significantly interact with one another.<ref name="Edwards"/>
