Fleur picked up something off the floor, popped it in her mouth, stood up, and met my gaze. She spun around and took off. She knew I was coming for it without me having to say it.
She is about a year from having developed the Theory of Mind. With it, she is able to know what I am thinking about the situation. In the classic situation, a researcher shows putting something in a box. Another moves it while the first is not present. Then the child asked where the first thinks it is located.
The taking off means she knows something of what I am thinking. She just would think I know what she knows.
Babies point at objects because they really want to touch them:
The first test revealed that we don’t necessarily angle a pointing finger in a way that will direct another observer’s attention towards the object we are pointing at. Rather, a virtual line runs from our eye through our fingertip and towards the object, as if we were reaching to touch the object.
The second test looked at the way we rotate our wrists when pointing at objects – for instance, how we point at a magnet attached to the right-facing side of a box that is placed directly in front of us. Even infants, if using their right hand to point at the magnet, will often rotate their wrist almost 180 degrees so that the pad of their pointing finger is directed towards the magnet, as if reaching to touch it.
The third tested how people interpret a pointing gesture being performed by someone else. It showed that 18-month-olds and 3-year-olds – but not nine-year-olds and adults – understand a pointing gesture to be an attempt by someone to touch an object, not an attempt to use their finger as an ‘arrow’ to direct attention in a certain direction.
When Fleur is done with dinner, she often exerts her displeasure at not having food in front of her. Such bad parents that we did not ensure she has just the right amount of food. Basically, if she has more than she wants to eat of something, then she throws it on the floor.
My wife often just gives something else. I prefer to provide options between two different kinds of food. So, this finding that children have a preference for the Recency Effect caught my eye.
Suspecting she might be picking left or right, the first several times I did switch them to see if she picked the same one. (She did.) My goal was to better understand her preferences.
Now, I know I need to design my choices for whether she is picking the second choice being a victim of this bias. Of course, she is not having to overburden her working memory capacity in these decisions. So, it probably does not apply.
Highlights from an Inc article on the benefits of music on the brain caught my attention:
- Musical training reorganizes neuron structures in the brain, specifically the corpus callosum which integrates the two sides plus areas involving verbal memory, spatial reasoning, and literacy.
- It improves long-term memory, in part because it teaches the hippocampus how to store memories and recall them on demand.
- It improves executive function, things like processing and retaining information, controlling behavior, making decisions, and problem solving
- Musicians tend to be more mentally alert with faster reaction times.
- They tend to have better statistical use of multisensory information, so they are better able to integrate inputs from the various senses.
- The earlier a musician starts, the more drastic the changes.
- Music reduces stress and improves happiness.*
- Increases blood flow in the brain.
* Wonder if all this singing we do with Fleur plus Galahad’s piano practice is part of why she is a happy child? After all, we’ve been leveraging singing as a way to distract Miss Wriggly.
Fleur has gleeful look when adults make weird sounds before doing something funny. Nose boops, tickles, and the like. She loves the stuff from people she likes. And doing it well, is a good way into her favorite people list.
Dopamine is thought of as the reward neurotransmitter. But, it is more complicated. It is what we get anticipating a reward. Say, you are playing a video game, dopamine surges to ensure you focus and persevere to achieve the level or match.
The noise right before tells her it is coming. Classical conditioning pairs a neutral stimulus with a desired one. The prior one is neutral the first time, but after she has paired it with the desired stimulus and anticipates the desired one. It seems like she enjoys the anticipation almost as much.
In getting mobile and manipulating objects, she is learning to use operant conditioning as well. She exerts her will on the world around her. This takes the form of doing the same thing over and over both using the same technique to confirm it works and adjusting to see what might work better. The other day she was trying to get into my tablet and tapping different spots to see how it reacted. You could see the Scientific Method in action: hypothesis, design test, execute test, evaluate result, new hypothesis.
Something I never thought about in university psychology classes was the impressive nature of linking things into causal chains. If this, then that. Over and over. Both forms of conditioning require understanding causation. The sponge that is Fleur’s brain seems to seek out understanding causation. And happiness to me is creating an environment for her try things and figure out how they work.
I love reading about the incongruity of the kids of friends. Part of why I started this is in hopes of reporting on the best of Fleur’s. The Atlantic has a good article “Knock Knock. Who’s There? Kids. Kids Who? Kids Tell Terrible Jokes.“:
“Even when their parents are feeding them ‘dad jokes’ to try to teach them about humor, half of the jokes that kids hear, they don’t quite get.” So it’s only natural, Dubinsky says, for some children to believe that a couple of absurd or mismatched concepts assembled into a familiar “knock-knock” or “What do you call …” structure adds up to a joke.
“Kids say, ‘Oh, jokes are about incongruity. I’ll show you some incongruity,’” Dubinsky says. “But they haven’t got the sophistication to construct an incongruity that’s going to be resolvable.”
Which, coincidentally, sometimes results in jokes that resemble a more advanced form of humor: an “anti-joke.” Anti-jokes deliberately deny the audience a clever or satisfying punch line, and they often serve as edgy or sophisticated commentary on jokes themselves.
Poor Fleur will suffer from “dad jokes.” She already hears them. She just has no idea she is inundated with them. And I love me some incongruity. So much of my attention is analyzing rules from social behavior to code to business process rules. I am always interested in the how and why to tease out mismatches to learn from them. Maybe that is why I love “dad jokes” so much?
