Final answer:
An actor must carefully understand the psychology of their character, focusing on character-centric actions rather than self-conscious performance. Embracing vulnerability is essential for authenticity, and actors must balance this with maintaining safety and trust in performances, all while considering the audience's experience.
Step-by-step explanation:
An actor must note carefully how the psychology of the character deals with various situations. This involves a deep understanding of the character's given circumstances, including the time period, relationships, and history. Through research and analysis, an actor uncovers the character's world and behavior patterns, which are used to sustain the character's substance and context within the narrative.
Beginning actors may initially focus inwardly due to self-consciousness, but they must learn to remain outwardly aware and responsive to external events from their character's perspective. This shift from self-preoccupation to a more character-centric approach is essential for actors to perform more believably and spontaneously.
