Cooperative and defective behavior depends on economic rules（i.e.,game theory） and follows psychological laws（e.g.,Prospect theory and other social psychology）.In this paper,we proposed a two-stage approach to probe into the process of individual behavior decision:non-rational and Prospect theory embedded rational ***,to capture the underlying mechanism of polarization and reversal of collective behavior in the smart environment,modeling of catastrophe in collective behavior is designed by integrating cusp catastrophe model and QSIM（i.e.,a qualitative simulation method）.Verifications and validations show the modeling results are suitable for explaining the dynamics of collective behavior in the smart environment.

The dynamics of two-word naming game incorporating the influence of biased assimilation is investigated in this paper. Firstly an extended naming game with biased assimilation（NGBA） is proposed. The hearer in NGBA accepts the received information in a biased manner, where he will refuse to accept the conveyed word with a predefined probability, if it is different from his own current memory. Secondly, the adaptive network is formulated, where the existing links may be reconnected so that the individual can influence other individuals over the population as much as possible. Numerical simulation results show that the population in NGBA can eventually reach consensus;the larger strength of biased assimilation on both words, the slower convergence speed, while larger strength of biased assimilation on only one word can slightly accelerate the convergence;larger population size can make the rate of convergence slower to a large extent when it increases from relatively small size, but such effect becomes minor when the population size is large;the behavior of adaptively reconnecting the existing links can greatly accelerate the rate of convergence.
