jimmy, I understand fully that early intervention does affect "the ability to learn and regulate emotions" however, the biological and genetic factor must not be undermined. If a child did not have a receptive brain to such education, or if they genetically have a trait that has been passed to them to not respond as much to such stimuli then the child would not learn as much. Would it be acceptable to say that environment only affects us by setting off certain behaviors biologically encoded in our DNA? We have yet to understand why humans sleep, what forms personalities, the subconscious, and other extremely important parts of human life so to say this question has been answered is not correct, in my opinion.
