Which term describes outward signs of emotion, such as facial expressions, posture, and tone of voice?

• A. Polygraph
• B. Catharsis Hypothesis
• C. Grit
• D. Expressive Behaviors

Answer: (D)

Outward signs of emotion are known as expressive behaviors. These are the visible nonverbal cues people use to read how someone is feeling—facial expressions, posture, and tone of voice—all observable signals that convey emotion even without words. Expressive behaviors specifically name these outward signals, making it the best fit for the question. A polygraph measures physiological responses to detect deception, not the visible expressions of emotion. The catharsis hypothesis talks about venting emotions to relieve tension, not about observable signals. Grit is about perseverance and long-term motivation, not about emotional display. So the term that captures these visible indicators is expressive behaviors.
