Towards human-robot interaction: A framing effect experiment

摘要

Decision making is a critical issue for humans operating unmanned vehicles. However, it is well admitted that many cognitive biases affect human judgments, leading to suboptimal or irrational decisions. The framing effect is a typical cognitive bias causing people to react differently depending on the context, the probability of the outcomes and how the problem is presented (loss vs. gain). There is a need to better understand the effects of these biases in operational contexts to optimize human-robot interactions. We therefore conducted an experiment involving a framing paradigm in a search and rescue mission (earthquake) and in a Mars rock sampling mission. We manipulated the framing (positive vs. negative) and the probability of the outcomes. Our findings revealed that the way the problem was presented (positively or negatively framed) and the emotional commitment (saving lives vs. collecting the good rock) statistically affected the choices made by the human operators.
