Transactional refers to interactions that are based on exchanges or transactions, often seen in business and communication contexts. These interactions focus on the give-and-take nature of relationships, where each party provides something of value to the other, such as goods, services, or information. In psychology, Transactional Analysis is a theory that examines social transactions to understand behavior and communication. It categorizes interactions into three ego states: Parent, Adult, and Child, helping individuals analyze their communication patterns and improve their interpersonal relationships.
