This is known as the real-simulator design (O'Connell, Shor & Orne, 1971;Orne, 1959;Sheehan, 1971). This design has been criticized by several investigators for a variety of reasons: (a) the inclusion of insusceptible 5s as simulators introduces subject variables (Reyher, 1967(Reyher, , 1969Spanos & Chaves, 1970;Sarbin & Coe, in press); (b) instructions to simulate alter the demand characteristics of the research for the simulating 5s (Reyher, 1967); (c) each of the ego involving or motivating instructions to the simulators represents a confounding variable (Reyher & Smyth, 1971); and (d) confusing phenotypic identity with genotypic identity (Bowers, 1971;Reyher, 1962Reyher, , 1967.…”
