Physical expressions refer to the non-verbal ways in which individuals convey emotions and thoughts through body language, facial expressions, and gestures. These expressions can include smiling, frowning, crossing arms, or maintaining eye contact, all of which can communicate feelings such as happiness, anger, or openness without the use of words. Understanding physical expressions is important in various fields, including psychology and communication. For instance, psychologists study how these expressions can reveal underlying emotions, while communicators use them to enhance interpersonal interactions. Recognizing and interpreting these cues can improve relationships and foster better understanding among individuals.
