Abstract: | P. W. Sheehan (see record 1974-10335-001) is erroneous in claiming to identify an artifact in T. X. Barber's (1969) model for hypnosis. While Sheehan shows empirically that the group differences in Barber's Ss do make a difference in suggestibility scores, this is a variable of constraint in terms of instructions, not an artifact.
