 If it is too much acting will be blocked, if it is too small action will be short-lived and be in want of intensity and impact.Helwig characterizes his approach both as dramaturgical (1958) and behavioristic (1964), the latter because overt behavior is seen as the primary phenomenon, to be explained from the interaction action-environment instead of hypothetical inner forces and features.His "behaviorism" starts, however, from very molar behavior units, unlike American behaviorism.
