The dispersion parameter of the prehistory distribution for a potential system driven by white noise is analyzed theoretically and by means of analog and digital experiments. Nonmonotonic evolution of the dispersion with time is shown to arise provided that the potential fulfills a certain condition. It does not necessitate the existence of an unstable point, but can occur in single-minimum potentials, both symmetric and asymmetric. [S0031-9007(98)05610-5] PACS numbers: 05.40. + j, 02.50. -r
