Abstract
Research on social contagion dynamics has not yet included a theoretical analysis of the ubiquitous
local trend imitation (LTI) characteristic. We propose a social contagion model with a tent-like adoption
probability to investigate the efect of this LTI characteristic on behavior spreading. We also propose
a generalized edge-based compartmental theory to describe the proposed model. Through extensive
numerical simulations and theoretical analyses, we fnd a crossover in the phase transition: when the
LTI capacity is strong, the growth of the fnal adoption size exhibits a second-order phase transition.
When the LTI capacity is weak, we see a frst-order phase transition. For a given behavioral information
transmission probability, there is an optimal LTI capacity that maximizes the fnal adoption size.
Finally we fnd that the above phenomena are not qualitatively afected by the heterogeneous degree
distribution. Our suggested theoretical predictions agree with the simulation results.
