Research indicates our brains edit the past to accommodate present views.
When we build a new memory, we gather little bits of information and store them together, say researchers at Northwestern University’s Feinberg School of Medicine. Then, when we bring up an old memory, those bits of information are melded with new bits relevant to present life. The resulting “memory” may be far from the event that actually happened.
The research, shared in an article in USAToday this past weekend, makes me re-think the accuracy of memoirs.
When I wrote the stories of a happy childhood in my memoir GROWING UP COUNTRY, many of the memories were as clear in my mind as if the events had happened last week instead of fifty years ago.
Though I have no doubt my childhood was happy and I’m comfortable with that picture, another memoir I wrote but didn’t publish covers the years of my first marriage. My first marriage included plenty of happy times, but the memoir dealt with those times that were not.
When I began to write those stories, I couldn’t remember much at all. The process of pulling those memories out of the deep recesses of my mind was difficult and often painful.
I felt devastating conflict between what I remembered and the way I viewed myself. In the course of the writing and with the caring support of my writing partners, the memories – and perhaps more important – my interpretation of those memories, adapted.
According to the Northwestern researchers, the brain’s ability to edit to current circumstances may explain why we can be convinced something happened when it didn’t.
In writing about my first marriage, I came to realize that certain things that I was convinced had happened could not have. They were a logistical impossibility. Yet, I was as convinced that those stories were true as I am that my childhood was happy.
Our memories are “a record of our current view of the past,” says Donna Rose Addis of the University of Auckland in New Zealand. Addis suggests the Northwestern University research has implications for understanding imagination.
I would say so! As a writer, I recognize there are many “truths.” I realize that each of us gets to tell our own story, yet I feel an obligation to be as close to factual accuracy as I can when I write memoir.
With research like this shining a light on how the brain works, I am left to wonder: are the memories I’ve had stored in the dusty corners of my mind accurate? Are the adapted memories that emerged as I wrote accurate? Or have I simply created a memory I can live with today.
What do you think my friends? How accurate can our memories be? How accurate do you believe writers need to be?
