When implemented in the field, smart-meter-based feedback interventions typically lag behind the presumed energy-saving potential of the technology. As we and others argue, part of the problem is that such interventions do not work equally well for everyone. The significance of a feedback intervention for actual energy savings depends on the rigor with which people make use of smart-meter-based information. In a quasi-experiment (N=186), we expectedly found that registering for a web portal that provided smart-meter-based feedback led to moderate energy savings conditional on a person's environmental attitude level. Apparently, a person's attitude discloses itself in the rigor with which this person makes use of an energy-saving opportunity. Hence, to effectively restrain consumption and save energy, environmental attitude is essential because, not only must people make appropriate behavioral choices, but they must also rigorously implement these choices.

Service robots that mimic human social behavior can appear polite. We tested the social and behavioral efficacy and legibility of two kinesic courtesy cues on people’s approval of a service robot. In a repeated-measures design, 29 volunteers were randomly assigned to two test situations: A participant and the robot simultaneously approached a bottleneck either next to each other or from opposite ends. Nested within these two situations were three courtesy cue conditions: The robot moved without any explicit courtesy cues, stopped, or moved aside and then stopped. We found statistically significant effects of the courtesy cues on people’s self-reported appreciation and the legibility of the robot’s motion. Behavioral observations indicated that the robot exhibiting two courtesy cues was less disruptive to the human’s own actions and was thus more behaviorally effective. This research demonstrates that kinesic politeness cues can be used effectively in the motion design of service robots.
