What encompasses verbal and non-verbal interactions between individuals?

The correct answer is communication because it is defined as the process of conveying information and meaning through various methods, which include both verbal (spoken or written language) and non-verbal (body language, gestures, facial expressions) forms of interaction. Communication is essential for forming connections, sharing ideas, and enabling understanding between individuals.

Behavior, while related, primarily refers to the actions or reactions of individuals in response to external or internal stimuli, rather than the specific exchange of information. Interaction might suggest the involvement between individuals but lacks the emphasis on the transfer of information central to communication. Socialization encompasses the broader process of learning and internalizing the norms and values of a culture, which includes communication but is not limited to the exchange of messages between individuals. Thus, the most accurate term for the entire spectrum of interactions—both verbal and non-verbal—is communication.
