This journal provides a focal point for the collection and distribution of systematically processed information about theory and practice in theatre. This issue contains discussions of (1) the effects of cognitive complexity on characterization depth and performance; (2) the effects of a director's system of communication on actor inventiveness and rehearsal atmosphere; (3) an instrument and a process used to identify musical compositions with greater accuracy than the written score, to account for interpretive differences among polished performing artists, and to match artists' interpretations with fundamental emotional expressions; (4) the effects of informal drama in influencing the self esteem of preadolescents; and (5) a programed approach to dialect training for the actor. Appendixes include an index to the previous five journal issues and an annotated bibliography on behavioral research in theatre. (AEA)
