Nonverbal communication refers to the transmission of information through signals other than spoken language.
These include gestures, glances, movements and other aspects that, subtly or obviously, influence the interpretation of a message.
While verbal communication focuses on content, nonverbal communication adds an additional layer of meaning that can transform the receiver's perception.
When analyzing human interactions, it is observed that non-verbal communication plays a crucial role in creating trust and emotional connection.
For example, a genuine smile can make a person feel welcome, while a calm tone of voice can ease tensions in a difficult conversation.
These elements are universal, although they vary slightly in their interpretation depending on the cultural context.
In Argentina, for example, closeness and physical contact are common ways of expressing warmth and empathy.
Furthermore, this form of communication can reinforce or contradict the spoken message.
If a person says “I’m fine” while avoiding eye contact and slouching, the nonverbal communication conveys a sense of discouragement that contrasts with the words.
This dual power highlights the importance of being aware of our gestures and expressions, especially in sensitive contexts such as job interviews or important negotiations.
