Study: Type of play affects learning

I remember when we were looking for toys for the 9 month age. We were good already with passive toys. So, we were more interested in in good active toys. Somehow, I had forgotten one of the basic concepts in psychology: the best way to study for a test is to replicate the conditions of the environment where the exam will be taken.

The best way to recall the test information is to create a study environment closely resembling the testing situation. The difference between an A and a B could be sitting in a desk in a quiet room over laying on a couch with Metallica pumping through headphones.

This study essentially confirms similar in infants. They cycle through calm attentiveness, wakeful activity, and crying. Recall is better if the state matches the state at encoding.

We cycle through these states, so I need to ensure multiple encoding opportunities to get maximum coverage. Don’t just wait for or try to achieve calm attentiveness for a learning opportunity. (I do talk about physics of the activity while Fleur is in physical play. Just need to mix it up a bit.)

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.

Book: Brain Rules for Baby

I loved the Brain Rules book. The original discussed why the brain works the way it does (including the studies) and gave specific activities one can do to boost the efficacy. An example: the brain is a major consumer of oxygen, so scientists have found that intense exercise improves function by getting more oxygenated blood to the brain.

I need to re-read it as it has been a decade. I recently got the baby one.

Some quotes:

Having a first child is like swallowing an intoxicating drink made of equal parts joy and terror, chased with a bucketful of transitions nobody ever tells you about.

This is 1,000% true.

As a scientist, I was very aware that watching a baby’s brain develop feels as if you have a front row seat to a biological Big Bang. The brain starts out as a single cell in the womb, quiet as a secret. Within a few weeks, it is pumping out nerve cells at an astonishing rate of 8,000 per second. Within a few months, it is on it’s way to becoming the world’s finest thinking machine.

Some notes I took.

  1. Perception begins at weeks for most senses. And memory persists after birth, but stimulation too early is harmful and later not going to make a genius.
  2. Everything is a balancing act. During pregnancy especially weight, nutrition, stress, exercise.
  3. Chronic or acute stress passes those hormones through the placenta and children seeing it stunt brain growth observing it. Husbands need to keep their wife not stressed. Happy is the ideal, but at least not stressed. This can be 8 IQ points.
  4. Exercise can reduce pushing time and reduce the time baby is without oxygen and reduce stunted brain development.
  5. Kinds of intelligence:
    1. Record information, aka crystallized intelligence.
    2. Improvisation
    3. Desire to explore
    4. Self-control
    5. Creativity
    6. Verbal communication
    7. Decoding nonverbal communication
  6. Ingredients for happy kids:
    1. a demanding but warm parenting style ( responsiveness & demandingness)
    2. comfort with your own emotions
    3. tracking your child’s emotions (don’t ignore & don’t helicopter)
    4. verbalizing emotions (describe emotions)
    5. running toward emotions (emotions are reflexive; behavior is a choice; be consistent with rules on behavior; turn intense feelings into teachable moments)
    6. two tons of empathy
  7. Behavior modification basic principles.

Overall, I really enjoyed the book. The thing I liked the most about the original was he named a rule and went on about why it is important and the research justifying it. This book lacked that simplistic and novel model, which put me off.
