Mary K. Rothbart

Dr. Rothbart has received several awards for her contributions in social and developmental psychology. In 2009, she received the Gold Medal Award for Life Achievement in the Science of Psychology from the American Psychological Foundation. She is also the recipient of the Block Award from the Society of Personality and Social Psychology, the Award for Distinguished Scientific Contributions to Child Development from the Society for Research in Child Development, and the G. Stanley Hall Award for Distinguished Contribution to Developmental Psychology from the American Psychological Association.

Rothbart has also done significant research on cognitive development. In 2007 she researched the differences in the human brain and how it changes over the years. She also did research on differences in education style and how this influences development. She also worked within the realm of social psychology in 2011 doing research on the brain states involved in hypnosis. She has used her knowledge of temperament in the varying ages of individuals and has begun applying it to other areas of psychology. In 2015 Rothbart did research involving the use of temperament in how mental disorders are viewed and categorized. Her most recent work done in 2016 was the role of temperament in personality.

Her methods of assessing infant temperament would evolve into the Infant Behavior Questionnaire, developed in 1981 and in a revised form still widely used today. This technique is commonly used among researchers studying infant behavior and temperament.

Rothbart earned her B.A in Psychology (1962) from Reed College in Portland, Oregon. She went on to earn her Ph.D in Psychology (1966) from Stanford University. Rothbart worked closely with developmental psychologist Eleanor Maccoby who served as her major advisor and mentor while she attended Stanford University. She has dedicated most of her work to the study of child development and temperament.

Mary Klevjord Rothbart (born May 22, 1940, in Lewistown, Montana) is professor emerita of psychology at the University of Oregon. She is known for her research in the fields of temperament and social development, emotional development, and development of attention. She was a co-founder of Birth to Three, a parent support and education program. She has written over 159 articles related to educational psychology, developmental psychology, developmental cognitive neuroscience and biological psychology. Rothbart has also authored and co-authored many books, including Becoming Who We Are, for which she received the Eleanor Maccoby Book Award from the American Psychological Association. Two other popular volumes by Rothbart are Temperament, a Handbook of Child Psychology, and Attention in Early Development: Themes and Variations.

Rothbart was born in Lewistown, Montana, in May 1940 and named Mary Louise Klevjord. Her father, whose family came from Norway, was a teacher and her mother was a housewife. Rothbart was the oldest of four daughters. Though born in Montana, Rothbart's father joined the civil service of the Air Force during World War II, which resulted in most of her early years living in Washington and Utah. After attending high school in Utah, she then enrolled at Reed College in Portland, Oregon. This is where her love of learning was strengthened and where she met her husband Myron Rothbart, a social psychologist. After graduating, both Rothbarts went to Stanford, where she graduated with a doctoral degree in developmental psychology. While at Stanford Rothbart gave birth to her first son, and 20 months later her second son. Her second son was born in Montreal, where Rothbart's husband was teaching. During her sons' early years, she took three years off to stay at home with them, which led her to research the development of temperament of children. She had looked into what research was available on child temperament at the time and there was not much work beyond an early study by Alexander Thomas and Stella Chess (New York Longitudinal Study). She would go on to spend countless hours interviewing and observing children and their emotional responses to outside stimuli in the process of developing the Infant Behavior Questionnaire in to assess temperament in small children. Rothbart then accepted a teaching position from the University of Oregon, where she spent the rest of her teaching and research career. She is now retired from her teaching career, but continues to conduct research.
