Self-Observation of Facial Expressions: A Hypothesis for Enhancing Self-Presentation and Confidence through Mental Modeling

This paper proposes a novel hypothesis: systematic self-observation of facial expressions enables individuals to construct a mental model of their expressive behaviors, facilitating intentional modification of expressions to enhance self-presentation and confidence. Grounded in the facial feedback hypothesis, self-perception theory, and mirror neuron research, this hypothesis posits that self-observation strengthens neural pathways associated with facial control and emotional regulation. By reviewing relevant literature, this paper articulates the theoretical mechanisms, proposes testable predictions, and discusses implications for social psychology, emotional regulation, and self-improvement interventions. While empirical validation is needed, this hypothesis offers a low-cost, self-directed approach to improving nonverbal communication and psychological well-being.
