On the speed of forgetting
(RESUME)

A conceptual model of forgetting based on a probabilistic approach is suggested: l-l0 exp (-kt), where l0 is the initial amount of information, and l - its value after the passage of time t. The model is in good agreement with experimental data. Analysis of literature enables the author to establish values of the parameter k-|dl/(ldt)| interpreted as the relative speed of information loss, or "the speed of forgetting": for "neutral" information its value is about 10-5 sec-1, for emotionally charged information (a meaningful text) the speed of forgetting is approximately 10 times less. Some ideas are presented concerning possible psychological means to increase the strength of emotionally bright information.
