The contribution of extensive background fluctuations to effective mass of a moving particle in an environment has been investigated and has showed the dependence on only the characteristic parameters of background fluctuation such as rate parameter (λ) in Boltzmann, variance (𝛼) in Gaussian and temperature (T) in back–body fluctuations. This field of interests is especially useful to provide physical insights of backgrounds. However, in the research of complex systems such as biological and ecological systems, it is not qualitatively adequate to model background fluctuations by a simple extensive distribution and to requires to take into account the non–extensiveness of the given background. In this work, an attempt to touch the non–extensiveness of an environment is analytically performed by using q–distributions and the dependence of effective mass on environmental non–extensive parameter is also discussed.
