Emotions are the drivers of every person's mood. Their role is to connect the individual with the world of people, events and things. They are divided into positive (happiness, surprise) and negative (sadness, fear, anger, disgust). The first emotions a child expresses are often reactions to pleasure or discomfort. A positive emotional state is expressed by staring, cooing, and smiling, while an unpleasant emotional state is expressed by frowning, crying, and an expression of disgust. Events in a child's early childhood have an impact on the child's overall development, and the dimensions that are considered the most important are physical, social-emotional and cognitive. Also, early interactions play an important role in shaping a child's emotional, social and cognitive skills. Socialization is an important process in which a child acquires knowledge, social skills, social sensitivity and behaviors that enable him to integrate into different groups. Emotional development affects the child's understanding of himself and the world around him, as well as his self-confidence, social relationships and ability to cope with challenges. The aim of the paper is to provide an overview of the relevant literature on the communication skill of expressing (verbalizing) emotions. Through a review of the relevant literature, the paper will point out the need to improve human communication skills related to the recognition and verbalization of emotions as one of the prerequisites for successful communication.
