3 graduate student experimenters' expectations about the stress reaction of 24 subjects to sensory deprivation or to an ambulatory control condition were factorially manipulated. No significant differences were found for experimenters' expectation, directly or through interaction. Results were interpreted as a refutation of the assumed pervasiveness of experimenter-bias effects.
