In this investigation, an observer variable is manipulated in an experimental context concerning the trajectory of electrons affected by their movement through a Stern-Gerlach apparatus. The basis in psychology concerning why the observer variable is significant in the experimental context is discussed. This investigation can serve as a prototype for more complicated investigations.22 pages, extension of papers by Snyder, Journal of Mind and Behavior, 1993, 14, 145-153 and 1995, 16, 151-171General Physicstext
