Transactional analysis (TA) is a theory of communication developed by Eric Berne in the 1950s. According to TA, all human interactions or "transactions" involve exchanges between three ego states - Parent, Adult, and Child. Berne identified common dysfunctional interaction patterns called "games" and developed tools like the Johari Window and script analysis to improve self-awareness and interpersonal relationships. The goal of TA is more open, empathetic communication through increasing awareness of one's own and others' behaviors and motivations.
