This week’s roundup is going out a day later than usual, as yesterday was the Global Climate Strike and Thought Shrapnel was striking too!
Here’s what I’ve been paying attention to this week:
- How does a computer ‘see’ gender? (Pew Research Center) — “Machine learning tools can bring substantial efficiency gains to analyzing large quantities of data, which is why we used this type of system to examine thousands of image search results in our own studies. But unlike traditional computer programs – which follow a highly prescribed set of steps to reach their conclusions – these systems make their decisions in ways that are largely hidden from public view, and highly dependent on the data used to train them. As such, they can be prone to systematic biases and can fail in ways that are difficult to understand and hard to predict in advance.”
- The Communication We Share with Apes (Nautilus) — “Many primate species use gestures to communicate with others in their groups. Wild chimpanzees have been seen to use at least 66 different hand signals and movements to communicate with each other. Lifting a foot toward another chimp means “climb on me,” while stroking their mouth can mean “give me the object.” In the past, researchers have also successfully taught apes more than 100 words in sign language.”
- Why degrowth is the only responsible way forward (openDemocracy) — “If we free our imagination from the liberal idea that well-being is best measured by the amount of stuff that we consume, we may discover that a good life could also be materially light. This is the idea of voluntary sufficiency. If we manage to decide collectively and democratically what is necessary and enough for a good life, then we could have plenty.”
- 3 times when procrastination can be a good thing (Fast Company) — “It took Leonardo da Vinci years to finish painting the Mona Lisa. You could say the masterpiece was created by a master procrastinator. Sure, da Vinci wasn’t under a tight deadline, but his lengthy process demonstrates the idea that we need to work through a lot of bad ideas before we get down to the good ones.”
- Why can’t we agree on what’s true any more? (The Guardian) — “What if, instead, we accepted the claim that all reports about the world are simply framings of one kind or another, which cannot but involve political and moral ideas about what counts as important? After all, reality becomes incoherent and overwhelming unless it is simplified and narrated in some way or other.
- A good teacher voice strikes fear into grown men (TES) — “A good teacher voice can cut glass if used with care. It can silence a class of children; it can strike fear into the hearts of grown men. A quiet, carefully placed “Excuse me”, with just the slightest emphasis on the “-se”, is more effective at stopping an argument between adults or children than any amount of reason.”
- Freeing software (John Ohno) — “The only way to set software free is to unshackle it from the needs of capital. And, capital has become so dependent upon software that an independent ecosystem of anti-capitalist software, sufficiently popular, can starve it of access to the speed and violence it needs to consume ever-doubling quantities of to survive.”
- Young People Are Going to Save Us All From Office Life (The New York Times) — “Today’s young workers have been called lazy and entitled. Could they, instead, be among the first to understand the proper role of work in life — and end up remaking work for everyone else?”
- Global climate strikes: Don’t say you’re sorry. We need people who can take action to TAKE ACTUAL ACTION (The Guardian) — “Brenda the civil disobedience penguin gives some handy dos and don’ts for your civil disobedience”
My kids will often ask me about what I was like at their age. It might be about how fast I swam a couple of length freestyle, it could be what music I was into, or when I went on a particular holiday I mentioned in passing. Of course, as I didn’t keep a diary as a child, these questions are almost impossible to answer. I simply can’t remember how old I was when certain things happened.
Over and above that, though, there’s some things that I’ve just completely forgotten. I only realise this when I see, hear, or perhaps smell something that reminds me of a thing that my conscious mind had chosen to leave behind. It’s particularly true of experiences from when we are very young. This phenomenon is known as ‘childhood amnesia’, as an article in Nautilus explains:
On average, people’s memories stretch no farther than age three and a half. Everything before then is a dark abyss. “This is a phenomenon of longstanding focus,” says Patricia Bauer of Emory University, a leading expert on memory development. “It demands our attention because it’s a paradox: Very young children show evidence of memory for events in their lives, yet as adults we have relatively few of these memories.”
In the last few years, scientists have finally started to unravel precisely what is happening in the brain around the time that we forsake recollection of our earliest years. “What we are adding to the story now is the biological basis,” says Paul Frankland, a neuroscientist at the Hospital for Sick Children in Toronto. This new science suggests that as a necessary part of the passage into adulthood, the brain must let go of much of our childhood.
Interestingly, our seven year-old daughter is on the cusp of this forgetting. She’s slowly forgetting things that she had no problem recalling even last year, and has to be prompted by photographs of the event or experience.
One experiment after another revealed that the memories of children 3 and younger do in fact persist, albeit with limitations. At 6 months of age, infants’ memories last for at least a day; at 9 months, for a month; by age 2, for a year. And in a landmark 1991 study, researchers discovered that four-and-a-half-year-olds could recall detailed memories from a trip to Disney World 18 months prior. Around age 6, however, children begin to forget many of these earliest memories. In a 2005 experiment by Bauer and her colleagues, five-and-a-half-year-olds remembered more than 80 percent of experiences they had at age 3, whereas seven-and-a-half-year-olds remembered less than 40 percent.
It’s fascinating, and also true of later experiences, although to a lesser extent. Our brains conceal some of our memories by rewiring our brain. This is all part of growing up.
This restructuring of memory circuits means that, while some of our childhood memories are truly gone, others persist in a scrambled, refracted way. Studies have shown that people can retrieve at least some childhood memories by responding to specific prompts—dredging up the earliest recollection associated with the word “milk,” for example—or by imagining a house, school, or specific location tied to a certain age and allowing the relevant memories to bubble up on their own.
So we shouldn’t worry too much about remembering childhood experiences in high-fidelity. After all, it’s important to be able to tell new stories to both ourselves and other people, casting prior experiences in a new light.
