The employ of different technologies has been constantly increasing in our daily life. From chatbots to automated cars, it is becoming normal to interact with some sort of technology and the functional relationship with it is essential to cover certain needs and expectations. The Sense of Agency (SoA) seems to play an important role in social interactions to facilitate the involvement in group tasks. In this way, the perceived involvement of a non-human agent would be sufficient to develop a cooperative environment between humans and computers. In order to understand this phenomena, the joint Go/NoGo tasks are commonly employed to investigate the perceptions of the individuals while performing the task together. The present research aimed to study the interactions while individuals perform a Go/NoGo task with a partner and, together with subjective ratings, determine whether the computer partner is perceived as similar to human partners; and, second, to explore to which extent the performance in the task differs between human partners and computer partners.
