Locus of control and the aggression inhibiting effects of aggressive humor appreciation

Empirical investigation into the theoretical connection between humor appreciation and aggression has provided a continued series of equivocal results. This experiment examined the proposition that previous inconsistencies were due to the lack of concern for individual locus of control. Female subjects, differentiated as internals and externals, received either an aggression arousal induction procedure or a neutral nonarousal procedure. Subjects were presented three stimulus situations: neutral humor, aggressive humor, or nonhumorous material, and assessed for mood state. Locus of control was found to be a significant variable in the effectiveness of aggressive humor to reduce aggressive mood. Internals were able to reduce aggressive mood through appreciation of aggressive humor and demonstrated preference for this humor type. Importance of internals' cognitive style interacting with humor content was found significant in relationship between humor and aggressive reduction.
