Kenneth L. Davis completed his Ph.D. with Jaak Panksepp on Opioids and the Social Behavior of Dogs. After teaching in a small college for four years, he gave up my search for an academic research position and left the academic world for a job in industry. Meanwhile, he continued his work with Panksepp on developing the Affective Neuroscience Personality Scales (ANPS). Davis has since focused on adjectives closely related to the six primary emotions measured in the ANPS and recently developed a short adjective personality assessment called the ANPS-AR consisting of 24 adjectives, which can be used to self-rate personality but which can also be used by observers to rate the personalities of others such a therapy patients. With Panksepp he authored The Emotional Foundations of Personality: A Neurobiological and Evolutionary Approach (W.W. Norton, 2018).
