Effects of Robot's Language and Attribute Framing on People's Risky Behavior.

With the globalization, it is essential to investigate the robot’s language on human-robot interaction. The robot’s information framing may also affect people’s behavior. This study investigated the effects of the robot’s language (native vs. foreign) and information frame (positive vs. negative) on people’s risky behavior in Balloon Analog Risk Task. The results indicated that participants’ behavior was less risky when the robot used the negative frame to represent the information. Furthermore, the effect of the robot’s information frame on participants’ risky behavior was less obvious when the robot used a foreign language. The use of a foreign language would reduce the framing effects in human-robot interaction. The effects of the robot’s language and information frame should not be neglected. The obtained findings can serve as a basis for the design of robots’ language and information presentation.
