A two-step cognitive model is outlined that explicates the key empirical findings on the relation between age and creative productivity. Two primary information-processing parameters, the ideation and elaboration rates, define a mathematical function that both describes the age curves and specifies how those curves vary across disciplines. To validate the model further, a nonlinear estimation program was applied to previously published tabulations on the longitudinal fluctuations in creative output. The resulting parameter estimates also yield the expected peak age and the creative half-life for each domain of achievement. Despite the prediction of a post-peak decline, the model's implications for creativity over the life span are optimistic.
