The article also mentions neuroscientist Elizabeth Phelps's research to support an attendant claim that "When the prefrontal cortex is under stress, our capacity for learning, memory, and decision-making is compromised". But her research on stress's effects on cognition that I can find actually suggests stress is often beneficial to learning and performance, and her work on fear response conditioning focuses on timing of interventions, not energetic expense or discomfort.
What's so worth hating about this kind of vacant-eyed patronizing crap, this "neuroscience-based approach" and "blueprint for L&D professionals", is how it authoritatively name-drops experts and science-y words as an appetizer, without inviting any actual engagement or understanding, and proceeds to dish up warmed-over PD workshop slop for the next 9/10ths of the article. Those L&D professionals may have no substantive understanding of neuroscience, but they know that you need to feel "discomfort" and bear "energetic expense".
