Great observation Lois. A distinction I didn't make clear in this article is that "Responsibility-Avoiders" are motivated by contact, which is about kinesthetic movement, real or imagined. They are called Rebels in the PCM model. Playful movement/activity is different from thrill and excitement, and is what helps ADHD people focus. This isn't a hard and fast rule, but the research is pretty strong. Thrill-Seekers are called Promoters in the PCM model. To learn more about this model, check out a free app called PocketPCM, available for Apple or Android.
