As commonly used, the phrase early influences denotes the conditioning of behavior by the experiences of very early life. Early experiences, however, do more than conditioning behavioural patterns; they also affect profoundly and lastingly many biological characteristics of the adult. I shall show that, in animals, events occurring during the very first days of life determine the initial growth rate, the maximum adult size, the efficiency in utilization of food, and the resistance to infection, malnutrition, and other stressful stimuli.
Early influences are, of course, at least [as] important in human life as they are in animal life. In fact, the experiments to be reported here were designed to provide experimental models for the study of socio-medical problems first recognized in human populations.
During the past century, for example, there has been a constant
