Abstract
Research studies have indicated that when subjects are given cues or information about the purpose of a research study the scores on a psychological measure tend to increase in a positive direction. In this study 100 undergraduate students were assigned to one of three treatment groups. The first group received information stating that high scores on the Minnesota Teacher Attitude Inventory (MTAI) revealed a potentially successful teacher. The second group obtained neutral information. The third group was told that high scores on the MTAI resulted in potentially poor teachers. The results indicated that both positive and negative information increased the scores of subjects on the MTAI and suggested that the validity of the MTAI might be compromised.
