Baby Einstein: Baby MacDonald
there were 17 scene changes; about one every three seconds …
and of course, it’s nothing like being on a real farm, right?
Adults watching this find it confabulating because your mind is trying to make a coherent narrative out of this. And there is no coherent narrative, it jumps all over the place!

Prolonged exposure to rapid image change during critical period of brain development ->
Precondition mind to expect high levels of stimulation ->
Innatention in later life.

She also wondered if teachers were adding to the problem by adjusting their lessons to accommodate shorter attention spans.  “Are we contributing to this?” Ms. Molina-Porter said.
“What’s going to happen when they don’t have constant entertainment?”

Scholars who study the role of media in society say no long-term studies have been done that adequately show how and if student attention span has changed because of the use of digital technology.
But there is mounting indirect evidence that constant use of technology can affect behavior, particularly in developing brains, because of heavy stimulation and rapid shifts in attention.

nearly 90 percent [of teachers] said that digital technologies were creating “an easily distracted generation with short attention spans.

The heavy technology use, Dr. Christakis said, “makes reality by comparison uninteresting.”
