Quizplus · Accepted Answer

Ebbinghaus used only himself as his experimental subject, which allowed him to have complete control over the conditions of his experiments and eliminate any potential confounding factors that could arise from different individuals having different prior experiences, abilities, or motivations. His use of a single subject also enabled him to collect rich, detailed data on the learning and forgetting curves of memory, which helped him to create the first scientific model of human memory.
