Final answer:
The universal emotion expressed with the whole body, not just the face, is happiness, as per Paul Ekman's research on universal emotions and their distinctive expressions.
Step-by-step explanation:
The emotion that is universal but is expressed with the whole body, not just the face, is happiness. While Paul Ekman's research identified seven universal emotions with distinctive facial expressions—happiness, surprise, sadness, fright, disgust, contempt, and anger—it's the emotion of happiness that is often shown through both the face and the body. This finding aligns with Darwin's observations in his seminal work, The Expression of Emotions in Man and Animals, suggesting that the physical displays associated with emotions are innate.
Furthermore, Ekman's work with isolated cultures supports the universality of these emotional expressions. Happiness, being a positive emotion, tends to manifest in outward expressions such as smiling, open body language, and gestures that convey joy and satisfaction, reflecting a full-body experience.
