Two different videotaped interviews were staged with the same individual-a college instructor who spoke English with a European accent.In one of the interviews the instructor was warm and friendly, in the other, cold and distant.The subjects who saw the warm instructor rated his appearance, mannerisms, and accent as appealing, whereas those who saw the cold instructor rated these attributes as irritating These results indicate that global evaluations of a person can induce altered evaluations of the person's attributes, even when there is sufficient information to allow for independent assessments of them.Furthermore, the subjects were unaware of this influence of global evaluations on ratings of attributes.In fact, the subjects who saw the cold instructor actually believed that the direction of influence was opposite to the true direction.They reported that their dislike of the instructor had no effect on their ratings of his attributes but that their dislike of his attributes had lowered their global evaluations of him.
