This study examined the experimenter-bias effect. In past studies, Es and Ss were college students and the criterion instrument was a person-perception task. The Es showed S a series of faces and asked to scale their judgment of whether the person depicted had been "experiencing failure or success". This study removed the Es from one of the two groups of college students Ss. Group I had high-expectancy instructions, while Group II had no E and read the instructions themselves. The conclusion is that the experimenter bias, in this case, may be a task bias built into the experimental paradigm.
