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.

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.

Smile timing

Fleur makes us work at times to get great smiles for photos. As she has gotten older, it seemed like she has gotten more crafty about getting more. Then I ran across this nugget of confirmation bias:

The research team found that by timing their smile precisely, babies can elicit maximum smiles with little effort on their part.

My wife fills up her phone trying to get the perfect smile because the toddler is manipulating the adults to get entertained enough to bestow upon us a photo worthy one.

Proud of her.

Being a Musician Is Good for the Brain

Highlights from an Inc article on the benefits of music on the brain caught my attention:

  1. 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.
  2. It improves long-term memory, in part because it teaches the hippocampus how to store memories and recall them on demand.
  3. It improves executive function, things like processing and retaining information, controlling behavior, making decisions, and problem solving
  4. Musicians tend to be more mentally alert with faster reaction times.
  5. They tend to have better statistical use of multisensory information, so they are better able to integrate inputs from the various senses.
  6. The earlier a musician starts, the more drastic the changes.
  7. Music reduces stress and improves happiness.*
  8. 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.
