In this paper, we aim to increase the understanding of human-robot interaction by considering
the goal orientation displayed by the robot (i.e., competitive vs. cooperative) and the role displayed by
each player (partner vs. opponent) in an entertainment group scenario. Sixty participants engaged in a
card game called Sueca (two robots and two humans). Each participant played with each of the other
players, and the goal orientation was manipulated by the set of verbal utterances displayed by the robot.
Using a coding scheme based on Bales Interaction Process Analysis, the video-recorded interactions were
analysed in terms of socioemotional positive, negative and task-oriented behaviours. A marginal multilevel
modelling analysis yielded significant interactions between the robotic addressee and the role the robot
displayed in the socioemotional and task-oriented behaviours. Overall, our main results demonstrated the
following: (1) Participants directed more behaviours towards partners than opponents, although most of
these behaviours occurred between humans when they were partners. (2) When comparing players in the
role of opponents, participants directed more socioemotional behaviours towards robots than towards the
other human player. (3) No difference in task-oriented behaviours was observed among any of the players
in this condition. These results suggest the occurrence of dierent behavioural patterns in competitive
and collaborative interactions with robots that might be useful to inform the future development of more
socially eective robots.
