The document discusses a study that examined how working with a robotic companion versus a human companion affects trust and work efficiency. In the study, participants were asked to navigate a maze and were given instructions by either a robot or human. The results showed that participants were more likely to follow instructions from a human and took longer on average when instructed by a human. However, participants who received instructions from the robot were more likely to deviate from the instructions and had a higher failure rate when navigating the maze. The hypothesis that working with a robot would increase efficiency was not supported.
