This video continues my rebuttal of Jordan Peterson's assertion that ADHD is primarily the result of a lack of opportunity for rough and tumble play, primarily in boys. It discusses Peterson's use of the animal research of Jaak Panksepp that found that socially isolated juvenile rats showed increased aggressive play when entering a social situation, although it dissipated with time. I am quite familiar with this research as Panksepp was on my dissertation committee and corresponded with me occasionally thereafter about the applicability of his findings to ADHD, then known as hyperactivity. After demonstrating the lack of comparability of rat play research to human play, the difficulties directly extrapolating from the rat brain to the human brain that is any times larger and more cortically developed, I review the findings in ADHD that directly refute Peterson's assertions. I then argue that Peterson's opinion implies that parents are to blame for their child's ADHD as they are the one's immediately responsible for their children's social environments -- a position that was held 50+. years ago that was resoundingly refuted by many subsequent studies. I then argue that such a position has no scientific standing, is worse than wrong, and is morally offensive given the voluminous research on the neurodevelopment and genetic nature of ADHD.

The video is just under 40 minutes long. I did not cut it into smaller videos as, like the closing arguments of a prosecuting attorney, this speech builds to a crescendo that should not be interrupted by frequent breaks.
