I happened to see the clip you had on prenatal brain development. Even though there are probably no studies; furthermore how would it be done? It would need to have a large sample size and follow these kids through at least 2 decades in my opinion. It is a difficult study to do but that does not mean there is no point to prenatal cognitive exercises. I was kind of surprised at how definitive the developmental psychologist from John Hopkins was. The mind is one of the least understood areas of the body. Maybe she is a healthcare hard ####, I have seen this type before speak hundred miles per hour and act like a know it all!

But the truth is there is no way to definitely say there is no point to prenatal or early childhood cognitive coaching. Even the newer research is showing things such as neurogensis and factors such as BDNF (bran derived nerve factor) amongst others play a major role in cognitive development and preservation. In regards to the segment based on what I know believe it is impossible to be so definitive and the jury is still out. . . As for spending cash on these things, probably not. It might better to read and interact with the kids and have them do various cognitive games. It is fascinating how children in extreme seclusion in their early years have serious cognitive impairments. So there is definitively much to learn in this area about the mind body connection. And even the mind environment connection. And hence feel her dismissiveness overall is seriously unwarranted.
