The nature of hypnotic performance following administration of the Carleton Skills Training program

30 low hypnotizable Ss were administered the Carleton Skills Training (CST) program, while 8 were assigned to a practice group. Prior to treatment, an attempt was made to facilitate training by altering the ecological conditions of the laboratory. All Ss were tested immediately after treatment, and trained Ss were retested after 5-7 months. Immediate training gains were large and were comparable in magnitude to those routinely found at Carleton University. In addition, (a) trained Ss responded comparably whether screened once or twice, (b) practice alone did not enhance hypnotic performance, and (c) natural high hypnotizable Ss obtained significantly larger Field Inventory of Hypnotic Depth (Field, 1965) scores than created high hypnotizables. Follow-up scores fell between scores posted at screening and immediately after training. Current findings are interpreted in the context of existing evidence concerning the CST program.
