Explanation:Ebbinghaus  as a researcher was often careful, and very cautious. He uses simple logical means or procedures. He always uses himself as the potential subject in his research (experiment) He gave himself some items to memorize on using some specific timeframe and waiting patiently, and therafter tried himself to see the amout of items he could remembered. Through the series of long, different research on himself, he was able to know that he could remember more of meaningful words than nonsense words and the words he acquired via learning, he could remember more than the ones he just spend a lot of time memorizing to himself.
