Asymptotic distribution functions of extremes were applied to sequences of various events; duration of marriages before divorce, length of courtship periods before engagement, loss of information from memory, and retrieval of words belonging to a specified category, etc. There are a large number of conditions leading to occurrence of each event. A sequence of events will be the distribution of minima (Weibull) if each event occurs as soon as one condition is met, and that of maxima if it occurs when all the conditions are fulfilled. This model is “soft” and hence covers various series because what is assumed is only the behavior of possible causes but not their substantive nature.
