What term refers to an external expression of one’s inner feelings about themselves or others?

The term that refers to an external expression of one’s inner feelings about themselves or others is "attitude." An attitude encompasses a person’s beliefs, feelings, and predispositions toward various objects, people, or situations. It manifests in behaviors, opinions, and even nonverbal cues, showcasing how individuals feel about themselves and their interactions with others.

In this context, while emotion describes an affective state or response that can be fleeting, it doesn’t necessarily convey a consistent viewpoint toward others. Mood typically refers to a more prolonged emotional state and may not be directed toward a specific object. Response denotes a reaction to a stimulus but lacks the comprehensive perspective that an attitude represents. Thus, "attitude" is distinct in that it integrates various emotional responses and beliefs into a more stable viewpoint, effectively expressing one’s inner feelings externally.
