It is the height of summer. I’m still struggling with learning Japanese, slow and steady, probably forever… But I’m also learning a lot about language learning itself, and it’s no secret that repetition is an important part of the process. And what better example to study than Haruhi Suzumiya’s Endless Eight (for people who don’t know, it’s a series of 8 episode displaying more or less the same events and it’s one of the greatest piece of art in anime history).
When I study Japanese, I write down how many new words I encounter, and how much of the dialog I understand for each episode (one per day). The structure of Endless Eight is a great source to showcase how much repetition helps with understanding.
As an extra datapoint, I’ve also revisited the same episode (6th, so that it’s in the “middle”) to see how much the learning sticks/how fast I forget after a week, month, 3 and 6 months (of continuous unrelated learning practice).
I don’t think this is solid enough to conclude anything, but it displays nicely how repetition yields diminishing return with stronger benefits at the start and how learning fades but a core does stick. I don’t think I was trying to get anything else out of this other than a pretty graph xD
