Final answer:
Ebbinghaus's forgetting curve suggests that after two months, the percentage forgotten would likely be greater than 75%, as 70% is already lost after 24 hours according to his research. Thus, none of the provided options (25%, 35%, 50%, or 75%) exactly match the expected memory loss after two months, per Ebbinghaus's findings.
Step-by-step explanation:
Based on the provided text, the percentage of an original message that you are most likely to forget after two months isn't explicitly stated. However, Hermann Ebbinghaus's research on the forgetting curve indicates that an average person will lose 50% of memorized information after 20 minutes and 70% after 24 hours. Although we don't have the exact figure for two months, it is reasonable to infer that the percentage forgotten would be equal to or greater than the loss after 24 hours.
Ebbinghaus's experiments into memory and the forgetting curve reveal profound insights into the decay of memory over time. These findings continue to be significant in the realms of psychology and educational theory. Therefore, the closest option to what we know from Ebbinghaus's forgetting curve is that after two months, the percentage forgotten would likely be greater than the options provided (it would be more than 75%).
