N2  - The propagation of a single act in a large population is supposed to depend on some external circumstance and on an "imitation component", where encounters with individuals who are performing or have already performed the act contribute to the tendency of an individual to perform it. The "tendency" to perform is supposed to be measured by the average frequency of stimuli, randomly distributed in time, impinging on the individual. The deduced equation is a relation between the fraction of the population who have performed the act and time, provided the time course of the "external circumstance" and the way in which the imitation component contributes are known. Several special cases are studied, in particular, cases without the imitation component, cases with imitation only, and various mixed cases. Examples are given of social situations in which such factors may operate and general suggestions are made for the systematization of observations and/or experiments to test the assumptions of the theory.
