In this paper, the authors report on the transition to young adulthood (18-25) in the highest functioning 18 individuals in our cohort (GAF '90) from a prospective longitudinal study of 76 lives followed from birth. These 18 individuals provide as clear a view as possible into the inner lives of people least distorted by psychopathology. This gives us a more crystalline photograph of psychic structure: the precipitant of family, society and psyche itself. Using a standard DSM IV criterion, Global Assessment Functioning (GAF), provides phenomenological homogeneity, but leaves us with heterogeneity of inner life. The 18 individuals had relatively rare drug or alcohol use and less sexual partners. Vocational functioning exceeded intimacy. Four had tumultuous pathways into adulthood. Nine were crossover cases, coming from sub-optimal mothering, with significant variation in gender distribution and intrapsychic structure. The paper discusses factors facilitating and inhibiting development and the nature of memories.
