In Transactional Analysis, what is a Transaction?

• A. Verbal and nonverbal communication between two people
• B. A message sent to the therapist's ego state
• C. A pattern of reinforcement in behavior modification
• D. The overt and hidden levels of a message

Answer: (A)

In Transactional Analysis, a Transaction is the basic unit of social interaction: one person sends a communication from one of their ego states (Parent, Adult, or Child) and the other person receives it and responds from an ego state. This can be verbal or nonverbal, and it’s the alignment between the sending ego state and the receiving ego state that determines how smoothly the interaction unfolds. When the response comes from the expected ego state, the transaction is complementary, keeping the conversation on track. If the response comes from a different ego state than expected, the transaction is crossed and misunderstandings or conflict can arise. A simple way to see it is: two people exchanging messages, where each message, taken together with the reply, constitutes one transaction. The option describing verbal and nonverbal communication between two people best captures that unit. The other options refer to narrower ideas (a message to the therapist’s ego state, patterns of reinforcement, or the idea of overt and covert aspects) that aren’t the defining concept of a transaction in TA.
