Average number of interactions between agent and human players of different colour for a game in the experimental setups. The varying agent concentrations in the colour groups resulted in different numbers of interactions between humans and agents. The numbers represent all the initiated interactions (i.e. requests sent). The number of initiated interactions in the purely human setup A and the purely agent based setup D are of the same range. However, the different group compositions in setups B and C have an effect on the number of initiated interactions in terms of human to agent and agent to human. It should be noted that the performance of individual groups in the game can lead to situations where a single group has not been able to form a large cluster and the other groups initiate more interactions towards them in order to maximize their own payoff, thus adjusting their behaviour towards more cooperative interactions. This type of helping behaviour towards the autonomous agents occurred because of the smaller cluster size resulting from the cooperative interactions’ tendency to break clusters in order to facilitate movement of other players. In total, the hybrid setups had more interactions on average (B with 90 and C with 86) than the purely agent or human setups (both A and D with 61).
