Cooperation is an effective way to maximize collective benefits, especially in modern human society. The issues on the emergence and maintenance of cooperation have attracted much attention in recent years. Here, we introduce the persistence parameter τ to characterize the time duration of choices held by individuals and consider the effects of τ on cooperation. We find that persistence could promote cooperation in a population no matter what the network structure is. Furthermore, the results on heterogeneous networks show that individuals with larger τ are more inclined to cooperate than those with smaller τ. Moreover, we investigate the effects of correlations between degree and persistence in scale-free networks and find that assortative matching could remarkably enhance cooperation whereas disassortative matching has adverse impacts on the evolution of cooperation.
