Winett Department of Psychology, University of Kentucky A pilot study is presented in which a typically used sign and sticker were compared to larger, strategically placed signs that more specifically indicated the target behavior of this study—turning-out lights in an unoccupied room. The typical sign and sticker were ineffective while the signs developed for the study appreciably decreased unnecessary lighting. The results are discussed in terms of the development of other signs and prompts applied to unnecessary lighting and other environmental problems. A. E.
