A 25-year follow-up: Some reflections on personality development over the long term

Highlights of our work over the last 30 years are reviewed; we begin with the infants whom we studied in the mid-1950s and conclude with impressions from a follow-up of their development 30 years later. The review begins with our first effort to propose a constructionist view of behavioral organization over the first 3 years of life, in terms of the negotiation by infant and caregiver of a sequence of adaptations in their interaction. This review includes a brief consideration of living systems and some of the principles that constrain the organization of behavior of the participants. Illustration of the way that these principles set up the “event-structure” of a system is given. In its recurrence, this event-structure sets the stage for psychic organization. The application of this early formulation to the study of 25- to 30-year outcome in these same infants studies the hypothesis that the configuration of adaptive strategies that the subject constructs by 2 years of age will be recognizable in the strategies which that individual employs in self-recognition and in the later construction of his ecologic niche at age 25. The logic or rules for this construction are set up over the first 2 years, as the infant's adaptation to the event-structure of the system is achieved and regulates later constructions. The bias set depends on the red thread of the subject's early inner experience of state and emotion (or affect) in relation to the infant's competence as agent in regulating states. A basis for inference as to this red thread of inner experience has been summarized in five propositions of construction. These highlight the patterning of competence in self-regulation within the individual's unique system. The role of infant state and of positive affects in this long-term influence is critical, as is the patterning of competence in enabling the infant to reconstruct desired states as goals in the unique configuration of adaptive solutions achieved for that system.
