Shortcuts: Rules (repost)

These are reposts of a series I did years ago on mental shortcuts.

After some debating with the toddler about whales vs sharks, I started down a thought experiment that Dunbar’s Number might not be about seeking justice and instead be about winning arguments.

Rules exist to help reduce the friction of society so that we can more easily work with strangers. Without rules, we need to have potentially damaging interactions with individuals, establish a series of data points about them to decide what kind of person they are to know how to handle them in the future. Instead, we create laws, policies, and traditions to define how we interact with each other. This frees our brains from Dunbar’s Number such that we can have larger social groups over that about 150 person limit.

We also have an instinctive bias to when others break the rules. People who severely or habitually do so need to be punished. We will claim it to be that others see that society will not tolerate the behavior, but really it is so we feel better that a rule breaker did not get away with it this time.

I started thinking about this because I had a conversation with a coworker about an odd claim about a rule. One problem with rules is there are too many for any individual to understand them all. We have specializations, so experts in an area are expected to know the rules for that knowledge domain.

People are human and may inform us about things that are less true and more desires of the way things ought to be. Traditions can sometimes fall into the latter. Sometimes when properly challenged, traditions find their way into being codified as laws or policies so that people properly behave.

Hammurabi almost 4,000 years ago solved this misunderstanding about what the rules are by writing them down. It really is a good way to handle it. One can read the rules oneself to check to see if how it was explained is correct or missing an important distinction.

And then, there is intentional rule breaking. Do you drive faster than the speed limit? Read all the terms for using a website? Criminals are deemed people who break the rules intentionally. Most of us are breaking some rules several times a day. Some intentionally, some by ignorance. Some because we were set up for failure. Some because the likelihood of being caught and punished are so low the wasted effort at complying is not worth it.

Shortcuts: Multitasking (repost)

These are reposts of a series I did years ago on mental shortcuts.

This one combines the worst of Illusions and Math. We trust our senses and inadequately assess risk.

We have limited capacities for attending to what happens around us. Two or more objects are not being held at the same time in memory. We switch between them. Once we have copied them from long term or permanent memory into working memory then short term, we can find those copies pretty quickly again. The more complicated the behavior and the more dissimilar the two or more tasks, the worse we multitask. By worse, I mean we are more prone to error and take longer time.

Given all the research and media coverage on how bad we are at multitasking and risks associated of texting and driving, I see people doing it daily. A law here allows police to write tickets to people who do it for the past few years. Texting is also pretty bad even on hands-free devices. Like other risky behaviors, these approaches are unlikely to stop humans from putting themselves in dangerous situations.

Shortcuts: Illusions (repost)

We like to think only those things we experience exist. Or even can experience. What about those things we can experience that do not or never did exist? That is what illusions are. They are cases where we trick the brain into believing something happened that did not. Or tricking the brain into thinking is experiencing reality when it is missing crucially important.

Michael Bach has a nice optical illusions page to demonstrate how easily our eyes are tricked. Every sense we have can be tricked. The food industry has worked wonders in devising how to trick our senses of smell and taste. When you feel something crawling on you and look to see nothing, that is your sense of touch going haywire.

Illusions can also be dangerous. Eyewitness testimony is the worst evidence we use in the legal system. Witnesses rarely capture and retain all the details. And how they are interviewed can allow them to fill in these gaps with other evidence and skew their results to confirm that same evidence. Say the police pick up a suspect and present that photo with others to a witness. The witness picks the photo of the suspect and later out of a line up. If the suspect actually only resembles the culprit, then these two steps confirm for the witness (and the police) the suspect’s guilt even though the witness saw someone else. We attend to similarities when searching and ignore the differences. And we will go with the closest option given choices.

Inattentional blindness also falls into my illusions category. Paying too much attention to something means we have no idea about what else is happening. The train operator on his cell phone not noticing the curve for which he needed to slow down and derailed. Multitasking while operating a vehicle is dangerous because of this.

Of course, everything we experience is really the interpretation of signals to the brain. One of my favorite experiments was people wore goggles that inverted the image so everything appeared upside down. The brain just adapts to the error and interprets the picture to the desired orientation. Do not like what you see? The brain can solve that problem. Another favorite experiment was ending phantom pain in missing limbs by using mirrors to make the limb appear to exist again.

My favorite metaphor for how the brain works is Object-Oriented Programming. Different parts of the brain perform different functions. The functions adapt (are reprogrammed or reconfigured) based on the needed interpretation of the data. Of course, the adaptations are not always 100% correct. Nor do they always adapt in time not to avoid errors.

Daddy’s Little Helper

The other day we went out to play. I grabbed a towel to dry off the slide, swings, and chairs. After watching me dry the slide and finding there was still some water, Fleur walked over to the towel, grabbed it, and dried the slide more. 

The blatant imitation had me tempted to roll around in the wet grass laughing. But, I was proud of the problem solving at play here. She totally assessed the problem, decided on the solution, and took care of it. It makes me excited and terrified for the future.

  1. She is developing the capability to do things we want her to all by herself.
  2. She is developing the capability to do things we don’t want her to all by herself.

Chimes

Last summer we spent a week at the house of my aunt and uncle. They have three chiming clocks. A grandfather clock and two small ones.

We have something similar. Auditory reminders at 9, 10, 3, 4, 5, 6 that announce: Check diaper. This is essentially our chimes. I find I don’t really need a clock during this period.

We don’t need the automated system when we get up from sleeping and prepare for it at naptime and bedtime. It is the in between that we need brought to our attention. In the focused zone, it can be easy to assume the other parent is going to take care of it. The chime brings back to our attention that maybe we should. We have saved on diaper cream since setting these up as we are better at making sure to address the diaper before the acidic defecation causes a rash.

On the plus side, Fleur loves the announcements. She runs around repeating it. If I am in the middle of work, then her running around letting us know keeps it on the brain.

Reminders are my main way of remembering to do things. The strange thing to me is this working from home means I am on my phone less. So, I miss more of the ones through it.

Paternal oxytocin

The one good thing about the shelter-in-place is the opportunity to be more engaged with my daughter. Before, I got her fed, dressed, and transported to daycare. Now, I still generally get her fed then periodically engage her in conversations, reading, and play. I can say that I do feel more connected to her.

Thus, the below makes sense to me:

Oxytocin increases in mothers, who provide a lot of affectionate contact and in fathers, who have a lot of stimulatory contact. Studies show that fathers highly involved in playing with their children have a higher level of oxytocin, compared with fathers, who show less stimulating activities. Moreover, brains of fathers involved in caregiving activities show an increase in grey matter volume.

Executive Function

Teenagers have an under developed prefrontal cortex. This is the part of the brain that interrupts emotional responses and considers the potential effects before acting. Teenagers look enough adult-like we want to treat them as adults, but they also have yet to grow the brain into their bodies.

Toddlers DGAF. Stimulus-response. Galahad is having to deal with the consequences of lack of planning, thinking three moves ahead, and a toddler who makes him pay the consequences.

He was in a bad mood, but he came upstairs to make a showing of his displeasure. Fleur who adores him now has made him sit and watch the same annoying video (we all hate) over and over.

She sounds so happy.

He sounds grumpier. Well, until she has worn him down.

My hope is that experiences like this will help him grow into being more mindful.

Pre-Theory of Mind

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.

Tryptophan, insulin, and melatonin

A few times now, I have gotten Fleur to sleep right after eating lunch. I know the daycare times it this way. It seemed arbitrary until I tried it and found it easy to get her to sleep.

Then I remembered something I read a while ago: Meats contain tryptophan. Fruits and sweets contain carbohydrates. At Thanksgiving and Christmas, we eat feel drowsy because of eating both. The carbohydrates prompts the release of insulin to use the branched-chain amino acids in rebuilding muscle, but the tryptophan is left behind. The tryptophan is metabolized into serotonin which is metabolized into melatonin. The last is what gives us that drowsy feel.

So, I now suspect the trick to getting the little one to take that nap is to get her full and use the excess melatonin as another nudge to “Go the #$@! to sleep!” That may also mean supper needs to be right before the bath when the neurotransmitter is maxed out.

Facebook Memories effect on recognition

I usually show Fleur videos I make of her doing something and gauge her enjoyment. Her face lights up seeing herself do something she just minutes prior. (Well, seconds because she now comes over to check the screen after seeing me record it.)

A Facebook memory popped up with her saying “dada” around the first time. I showed her that video and got a puzzled expression. She likely did not recognize herself. nor remembered the event. But, she quickly changed the expression to amusement, so I wonder what she was thinking about it.

Facebook Memories is an useful tool to trigger fond memories about past events. (Though, I vaguebooked too much.) Seeing old milestones can change a frustrating day into a good one.
