Transactional Analysis (TA) refers to a wide-ranging set of theories about the human personality. It provides an unambiguous and logical framework within which we can understand and analyze ourselves—our motives, our behavior, and our interactions with others. The principles of TA can be applied universally—at home, in the workplace, at clubs and restaurants, at sporting events, in social occasions, and so on. TA was originally developed by the American psychoanalyst Dr Eric Berne in the 1950s. After his untimely death in 1970, the existing TA theory was substantially enlarged and added to by a host of other illustrious contributors.
