Behavioral signs refer to observable actions or reactions that indicate a person's emotional state or mental condition. These signs can include changes in body language, such as crossed arms or avoiding eye contact, as well as shifts in tone of voice or speech patterns. Understanding these behaviors can help identify feelings like stress, anxiety, or happiness. In various contexts, such as psychology or animal behavior, recognizing behavioral signs is crucial for effective communication and interaction. For instance, a dog may show signs of aggression through growling or baring teeth, while a child might express discomfort by withdrawing from social situations.
