What if i told you that children who is peeking through the window into the classroom would be more observant about what is being told rather than someone in the classroom itself.
Brain is funny, the fun and comic part of brain is how it has its quirks. It can work beautifully but comes with its caveats
the moment brains are streamlined they cannot really observe and think, the observation window closes. The pre-fontrol cortex of conscious brain gets activated and that is devoid of any ideas and deep thoughts.
