“…Some are simply case studies (e.g., [26]), others engage larger participant samples (e.g., [27]), some studies investigate the effects of the robot in the context of specific tasks (e.g., [20]), some leave the interaction free and open to what participants want to make of it, constrained just by the robots capabilities (e.g., [28]). Some of the robots used are designed with clinical applications in mind, such as assisting children with autism (e.g., [29]) or providing couples therapy (e.g., [30]), but many of them are intended for general use, for purposes such as promoting inter-generational interactions (e.g., [31]). Finally, some of these studies were conducted in lab settings (e.g., [27]) while others in more naturalistic settings such as nursing homes (e.g., [32]).…”
