Emotional expressions are the visible signs of our feelings, often conveyed through facial expressions, body language, and vocal tone. These expressions help communicate emotions like happiness, sadness, anger, and surprise, allowing others to understand how we feel. For example, a smile typically indicates happiness, while a frown may suggest sadness or displeasure. Different cultures may have unique ways of expressing emotions, but many basic expressions are universally recognized. Research in psychology shows that even infants display emotional expressions, indicating that these signals are innate. Understanding emotional expressions can improve communication and strengthen relationships among individuals.
