Modulating the Intentional Stance: Humanoid Robots, Narrative and Autistic Traits

Abstract

To enhance collaboration between humans and robots it might be important to trigger towards humanoid robots, similar social cognitive mechanisms that are triggered towards humans, such as the adoption of the intentional stance (i.e., explaining an agents behavior with reference to mental states). This study aimed (1) to measure whether a film modulates participants’ tendency to adopt the intentional stance toward a humanoid robot and; (2) to investigate whether autistic traits affects this adoption. We administered two subscales of the InStance Test (IST) (i.e. ‘isolated robot’ subscale and ‘social robot’ subscale) before and after participants watched a film depicting an interaction between a humanoid robot and a human. On the isolated robot subscale, individuals with low autistic traits were more likely to adopt the intentional stance towards a humanoid robot after they watched the film, but there was no effect on individuals with high autistic traits. On the social robot subscale (i.e. when the robot is interacting with a human) both individuals with low and high autistic traits decreased in their adoption of the intentional stance after they watched the film. This suggests that the content of the narrative and an individual’s social cognitive abilities, affects the degree to which the intentional stance towards a humanoid robot is adopted.
