Abstract
Thepresent article advances a model of humor development extending from late adolescence until about age 60. Previously advanced models of humor development during the preadolescent years are reviewed, and issues related to the proposal of models of adult humor development are discussed. The developmental model presented here drawsfrom a series of factor-analytic studies which document the importance of two principal humor-appreciation factors (nonsense and incongruity plus resolution), andfrom a broad ränge of data demonstrating age-related changes in personality measures closely associated with these two factors. Separate attention is given by the model to positive (funniness) and negative (aversiveness) aspects ofreactions to cartoons andjokes.
