Emotional contagion reveals the fascinating way emotions spread among individuals. Through verbal and nonverbal signals, one person's emotions can influence the emotional atmosphere of others, creating a shared ambiance and enhancing empathy and interpersonal connection. In recent years, interest in this process has significantly increased due to scientific research, and an increasingly important role has been attributed to the synergy between psychology, physiology, and the application of artificial intelligence in these fields. One of these innovative directions involves the application of machine learning techniques in the field of facial expression recognition. In this context, advanced computational algorithms can categorize emotions represented in photographs with increasing accuracy.
