She focused on the construct of organized choices in the late 1950s. Her concerns about vocational interests led to a longitudinal study of the broader question of the directions of development that interests and personality take. A major research finding was that, as people thought about careers, dislikes and avoidances were more important than likes. This research led to the study of how choices organized peoples' lives. She developed the Choice Pattern Technique, that required people to indicate their construals of occupations and free-time activities. In 1962, she received the Fulbright scholarship to work at the University of Amsterdam. This allowed her to test her ideas and methods cross-culturally. Her research was extended to India and Australia and expanded to take in values, daily activities, and future time-perspectives in adolescents.
