Lorna Smith Benjamin
She received her B.A. in Psychology from Oberlin College in Ohio, and her Masters and Ph.D. from the University of Wisconsin, where she studied under Harry Harlow, working with the baby monkeys in his famous "wire mother" experiment.
Dr. Benjamin has practiced as a licensed psychologist in Wisconsin and Utah. She taught at the University of Wisconsin Medical School from 1971 to 1986 and has been Professor of Psychology at the University of Utah since 1988.
In 1968 she began work on the Structural Analysis of Social Behavior (SASB), a method she invented to categorize personality disorders. Originally conceived as a tool for studying primate behavior, SASB was well-suited to understanding personality disorders when they were first described in the Diagnostic and Statistical Manual of Mental Disorders in 1980. SASB describes human relationships as fitting along two axes: "love-hate," and "enmeshment-differentiation," with the additional dimension of "interpersonal focus."  Dr. Benjamin received an honorary degree from the University of Umea, Sweden, for her work with SASB.
After many years of work on the SASB model, Dr. Benjamin used its insights to develop Interpersonal Reconstructive Therapy (IRT). Rather than concentrating on the amelioration of symptoms (except in crisis situations), IRT focuses on identifying the patterns underlying a patient's maladaptive behavior and guiding them toward the formation of new, healthier patterns. SASB is used both to aid patients in understanding problems in their relationships, and to help them conceive of the form that improved relationships would take.
