In preparation and rehearsal, the actor develops imaginary stimuli, which often consist of sensory details of the circumstances, in order to provoke an organic, subconscious response in performance. These "inner objects of attention" (often abbreviated to "inner objects" or "contacts") help to support the emergence of an "unbroken line" of experiencing through a performance, which constitutes the inner life of the role. An "unbroken line" describes the actor's ability to focus attention exclusively on the fictional world of the drama throughout a performance, rather than becoming distracted by the scrutiny of the audience, the presence of a camera crew, or concerns relating to the actor's experience in the real world offstage or outside the world of the drama. In a rehearsal process, at first, the "line" of experiencing will be patchy and broken; as preparation and rehearsals develop, it becomes increasingly sustained and unbroken.
