That long blog post title is the summary of a very interesting piece of research just written up in Cognitive Daily. This is worth going over and taking a peek at the original post, because it’s quite an interesting piece of research.
The research question was whether people’s memories follow a predictable pattern. After all, we seem to remember more stuff from our 20’s and 30’s than, say, our 60’s. The researchers found, basically, that more life-defining events happen in our 20’s and 30’s (like marriage, having kids) and those events create more long-lasting memories. I’m grossly paraphrasing here, so take a look at the original post for the clearer picture.
Cognitive Daily says:
This corresponds well to other researchers who have found that immigrants remember more details about the years surrounding their time of immigration than non-immigrants. So if you immigrate in your 30s, you’re more likely to have memories from your 30s than someone who immigrated in her 20s. Other studies have found a memory bump in people from Bangladesh corresponding to a period of political unrest in that country. So it seems that our memories are affected more by the events in our lives than just the physical development of our brains. We’re not all destined to remember more of our teens and 20s than other years; we’re just more likely to experience significant, life-changing events in those years than others.
