The Neurobiology of Human Super-communication: Insights for Medicine and Business

引用

World Journal of Neuroscience 2021年第4期11卷 287-306页

作者： Michael Hoffmann Department of Neurology University of Central Florida Orlando VA Medical Center Veteran’s Blvd Lake Nona Orlando Florida USA

Background: Much adversity in our lives can be traced to a communication breakdown. To communicate well, it helps to understand how our brains and its communication hardware and software were assembled in the first place. With these insights, comes a better understanding not only how we can best communicate, but also why it is that way. We can be heard globally but fail to relate to someone beside us. Current modes of human communication: Electronic communication has had stupendous impacts, but cannot accomplish the fine-tuned, penta-sensory input and multimodal output communication abilities we developed over millions of years as primates. Even those developed before the age of mammals, such as scent and sound, continue to influence and modulate our more dominant vision sense. Hence, video-conferencing or skyping is unlikely to reliably relay critical pupillometrics, facial micro expressions, body postures, leg movements or scents. Although convenient to dispatch an email, twitter or facebook message at any time during a 24-hour period, the intended message or its impact may not be the optimal one. The remedy exists in knowing what communication tools should be used for what purpose. Much of our interaction involves important decisions, maneuvers, counseling and visionary ideas that are most effectively communicated with the 10 communication modalities we evolved with. Deployment of our communication modalities: An overview of the communication unit assembly process and prodigious communication abilities is presented and how to use these features to propel us back to our super communicator status amongst our workers, patients, peers and colleagues.
