Weakness of theory by hermann ebbinghaus?

Hermann Ebbinghaus's theory, particularly his forgetting curve, has been criticized for its reliance on self-reported data from a limited sample of nonsense syllables, which may not accurately represent real-world memory retention. His experimental methods lacked ecological validity, as they did not account for the complexities of meaningful information and emotional factors that influence memory. Additionally, Ebbinghaus's focus on rote memorization overlooks the role of context and individual differences in learning and memory processes.
