The Effects of Induced "E" [Experimenter] Bias on the Reading of Instructions during a Behavioral Experiment.
Kennedy, John J.; And Others
Eight graduate students were used as experimenters in this study to assess the effects of experimentally induced experimenter outcome bias with respect to selected suprasegmental phenomena (pitch, stress, and terminal intonation) emitted by the experimenters during the instruction reading phase of a behavioral experiment. Experimenters were led to expect differential conditioning performance from the subjects prior to the experiment. The subjects, 24 undergraduate students, were informed as to the nature of the experiment and were instructed to provide results which were compatible with the experimenters' expectations. The experimenters' directions to the subjects were audio-taped and rated by trained judges. Analyses of data produced several marginal findings but generally failed to demonstrate that bias is communicated through systematic variations in the measured language features. It was noted, however, that the response measures analyzed in this study were more specific than measures examined in earlier research and that the failure to uncover anticipated relationships suggests the study direct attention to an anomaly or inconsistency in the chain of logic underlying a substantive phenomenon which can serve to prompt further exploration and clarification.
