Potential new SIDS explanation

A new study correlates SIDS to a biological marker present in normal amounts babies at birth for babies who survive and lower in babies who don’t.

BChEsa, measured in dried blood spots taken 2-3 days after birth, was lower in babies who subsequently died of SIDS compared to surviving controls and other Non-SIDS deaths. We conclude that a previously unidentified cholinergic deficit, identifiable by abnormal -BChEsa, is present at birth in SIDS babies and represents a measurable, specific vulnerability prior to their death.

Correlation does not mean causation, but it is an intriguing area for more exploration to find a solution to a devastating problem for parents.

Parents receive a lot of sometimes contradictory advice on how to prevent SIDS. And should they lose a child to it, they could wonder what they did wrong.

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.)
