Do a robot's social skills and its objection discourage interactants from switching the robot off?

PloS one Jul 31, 2018
Building on the notion that people respond to media as if they were real, switching off a robot which exhibits lifelike behavior implies an interesting situation. In an experimental lab study with a 2x2 between-subjects-design (N = 85), people were g...
