United States Navy Miniature Naval Experimental Psychologist / Aviation Physiologist Insignia
Criteria: The Aerospace Experimental Psychologist insignia is a military badge of the United States Navy which is issued to those members of the Navy Medical Service Corps who have been qualified as in-flight aviation observers with certification in psychology, in particular the psychology of in-flight aircraft close quarters and the mental stress of possible combat situations.
The Aerospace Experimental Psychologist insignia is one of the rarest badges of the United States Navy. Those obtaining the device must complete a doctoral degree in experimental, industrial-organizational, or clinical psychology, successfully pass the personal qualification standard (PQS) examination, and must complete standard aviation indoctrination training. The Aerospace Experimental Psychologist insignia is then only presented after final certification and completion of a pre-determined number of flight instruction hours.
