Psychologists generally agree on the importance of early events in personality development, yet until now there has not been an opportunity to look at the personal lives of a group of adults over a considerable time. Subjects examined were 16 men and 44 women, parents of the subjects of the Guidance Study, a longitudinal study of the Institute of…
