Experimenter Bias Effect At Varying Levels Of Motivation, Leslie Marie Slade Gray

All Master's Theses

This study examined the effects of experimenter motivation upon the experimenter bias effect on a person perception task. It was hypothesized that the experimenter bias effect would decrease as reward and threat of punishment increased.

Thirty-five experimenters were randomly assigned to five treatment groups including a control group, two reward groups, and two punishment conditions. Each experimenter administered the photo task to two subjects. The results failed to support the experimental hypotheses.
