In this exploratory study of humor, it was hypothesized that responses to humorous material are related to each person's needs. Form B of the IPAT Humor Test of Personality and the Stern Activities Index were administered to 276 volunteer college students as measures of humor preference and needs, respectively. The results of the study suggest male/female differences in humor preferences as well as in needs patterns, which influence responses to funny material. Humor-preference patterns are suggested as ways of viewing sense of humor and related need constellations. An "identifier-desirer" factor is hypothesized as a possible variable in future research.
