Abstract
Previous research showed that energy consumption feedback of a social nature resulted in less energy consumption than factual energy consumption feedback. However, it was not clear which elements of social feedback (i.e. evaluation of behavior, the use of speech or the social appearance of the feedback source) caused this higher persuasiveness. In a first experiment we studied the role of evaluation by comparing the energy consumption of participants who received factual, evaluative or social feedback while using a virtual washing machine. The results suggested that social evaluative feedback resulted in lower energy consumption than both factual and evaluative feedback. In the second experiment we examined the role of speech and physical appearance in enhancing the persuasiveness of evaluative feedback. Overall, the current research suggests that the addition of only one social cue is sufficient to enhance the persuasiveness of evaluative feedback, while combining both cues will not further enhance persuasiveness.
