The term psychological templates, or psych template for short, referred to the personality and experiences of a human being.

In the final years of the Terran Federation, it was possible to replace a person's psych template with another, even a fictitious one.

During Operation Ark, it was decided by Chief Administrator Eric Langhorne, and Chief Psychologist Dr. Adorée Bédard to replace the psych templates of almost all eight million colonists within the Ark fleet. This was done for several reasons. Aside from preventing the reemergence of technology that would attract the Gbaba, they also thought to better prepare the colonists for a physcially demanding lifestyle of farming, animal husbandry, and hunting.

In nearly all cases the replacement of the psych templates was a success, with very few colonists being aware of their previous lives. (OAR)
