Abstract
We analyze the dynamical response of a nonlinear stochastic model with mean-field coupling driven by a time-sinusoidal external field. The L angevin equation for the model is solved numerically, and the results indicate the possibility of observing stochastic resonant amplificatio n of the driving amplitude. The influence of the mean-field coupling o n the typical stochastic resonance effects is pointed out.
