Abstract: The behaviors of humans are not always profit-driven in public goods games (PGG). In addition, social preference and decision-making might be influenced, even changed by heuristics and conformity in the real life. Motivated by the facts, we would like to investigate the role of emotional system in cooperative behaviors of structured population in PGG. Meantime, the effects of diffusion of influence are studied in structured population. Numerical simulation results are indicated that emotions play very significant role indeed in emergence and maintenance of cooperation in structured populations in PGG. However, the influences of emotions on others are limited due to diminishing of influence diffusion and the existence of pure defectors. What is more, conformity, to some extent, could drive potentially more people to accept cooperative strategy with higher probability. Higher-level cooperation could be promoted as increasing values of synergy factors, but while the effects might diminish gradually as increasing number of positive heuristic players and conformist. Our work may be beneficial to address the social dilemmas in PGG.
