The first modern office workstations were called the Action Office 1, 1964. Knowledge workers using that first design began to have mental breaks. By 1968 the problem was solved with the cubicle.

Cubicles are designed so that a concentrating worker cannot subliminally detect threat-movement in peripheral vision to trigger the vision startle reflex. The startle reflex is a hard wired part of human physiology. It cannot be turned off.

If you can learn to ignore movement in peripheral vision the startle will stop. But your brain continues to subliminally detect threat-movement and attempts to trigger the startle.

That threat detection and the brain’s reaction is a Subliminal Distraction, the name of this phenomenon. SD is explained in college psychology under psychophysics.

With enough exposure the subliminal appreciation of threat will color thought and reason. Typical symptoms are fear, paranoia, panic attacks, depression and thoughts of suicide.

VisionAndPsychosis.Net proposes this phenomenon is the cause of college suicides, and student disappearances. No school deliberately provides Cubicle Level Protection for student study areas or warns students in apartments or two person dorm rooms. A library carrel is full Cubicle Level Protection;
