I am very excited about this.
This is, as far as I know, the first study to attempt to measure the degree of chaos in the home.
The researchers in an earlier-mentioned study (Related: Poor children have smaller brains) speculated that “poor families tend to live more chaotic lives, and that stress could inhibit healthy brain development.” The current study seems to indicate that it is directly so.
As of this writing, my hypothesis has become as follows: the chaos of a growing child’s environment causes comparatively more resources to be devoted to the limbic system and less to the cerebral cortex, resulting in a body with reduced capacity to learn.
