The DR5 model
In this episode, Dr. Zab Johnson, Dr. Al’ai Alvarez, and Dr Preston Cline will break down the DR5 model using a Trauma Resuscitation scenario.
The DR5 represents the latest version of the original MCTI Learning Diagnostic Tool (The LERP and then the DR4) that was developed through a collaborative inquiry process between the Mission Critical Team Institute, Naval Special Warfare, and the Wharton Neuroscience Initiative (UPENN), to improve the training for hostage rescue teams. This version was specifically developed for use in medical resuscitation. As always, it is designed as a tool to help Instructor Cadre improve performance within immersion events and is currently being utilized by teams worldwide. Initially created to move past the all too common “You Suck! Suck Less!” instructor/student interaction by providing instructors a more precise language to overcome the Tacit Knowledge Transfer Problem . This is the problem that experts face when trying to explain or articulate their expertise (e.g., Having the skill to ride a bike versus explaining that skill to another). Using research from Psychology, Education, and Neuroscience, the DR5 model breaks down the immersion event into 5 distinct areas of Detection, Recognition, Reaction, Response, Reset, and Reflection. While neurologically, these stages do not behave sequentially , the model provides Instructor Cadres a mechanism for specificity  to diagnose better and mediate learning within and after immersion events.

Executive Director, Wharton Neuroscience Initiative
Senior Fellow, Wharton Neuroscience Initiative
Elizabeth (Zab) Johnson is the executive director and senior fellow of the Wharton Neuroscience Initiative. Her research focuses on vision and visual behavior. Her work spans physiological approaches in the retina and early visual cortex to using eye tracking to investigate how human observers look and navigate through the world, how these processes unfold over time and with experience, and the role of social cognition and decision making in these processes. She is an expert on color vision. She received her PhD in Neural Science at New York University.
