Babyhood Non-memories

There’s this book, Does My Goldfish Know Who I Am?, on simple answers to great questions kids ask. Neuroscientist Tali Sharot had this answer to an 8-year-old's question about why we don't have memories from the time we were babies and toddlers:
“We use our brain for memory. In the first few years of our lives, our brain grows and changes a lot, just like the rest of our body. Scientists think that because the parts of our brain that are important for memory have not fully developed when we are babies, we are unable to store memories in the same way that we do when we are older.

Also, when we are very young we do not know how to speak. This makes it difficult to keep events in your mind and remember them later, because we use language to remember what happened in the past.”

I tend to both agree and disagree with the first part of the answer. On the one hand, babies learn very fast. How can they do that if they have no way to “store” data and associations? On the other hand, when my daughter was a baby, during her midnight feeds, I used to try to make the sound of a spoon mixing her Lactogen as a signal that milk was on the way, but she never got the message… she just cried louder!

The second part of the answer does make sense. If we didn’t have a “data format” (aka language) identified as babies and toddlers, what are the odds that something that was logged back then in baby gibberish format would still be interpretable later once we’d learnt a language? Was the old data wiped clean as being not read’able anymore?

Whether or not Sharot’s answer is right, it would be way more fun if the correct answer is what Calvin suspected:

Student of the Year

As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid
