  Perspective taking, which allows people to imagine another's thinking and
goals, is known to be an effective method for promoting prosocial behaviors in
human-computer interactions. However, most of the previous studies have focused
on simulating human-human interactions in the real world by offering
participants experiences related to various moral tasks through the use of
human-like virtual agents. In this study, we investigated whether taking the
perspective of a different robot in a robot-altruistic task would influence the
social behaviors of participants in a dictator game. Our findings showed that
participants who watched the help-receiver view exhibited more altruistic
behaviors toward a robot than those who watched the help-provider view. We also
found that, after watching robots from two different viewpoints in the task,
participants did not change their behavior toward another participant.
