We propose the modified two-state approximation to investigate the nonlinear regime of stochastic resonance phenomenon. The new model corresponds to some non-trivial cumulant truncation scheme. A comparison between the results of ordinary cumulant truncation schemes (Gaussian and excess approximations) and obtained in the framework of new method for the power amplification factor is performed.
