Recently, it was shown that the spreading of stereotypical escape behavior (startle) in fish schools corresponds to a complex contagion process [1]. Here, we will discuss the modeling of such behavioral cascades using an extension of the generalized contagion model proposed by Dodds & Watts [2]. In particular, using networks extracted from experimental data, we will identify and discuss parameter regions providing best agreement with experimentally observed cascades. Furthermore, we will apply our modeling ansatz to new experiments on the impact of different risk perception on the behavioral contagion dynamics in fish schools.
