Attachment Stability from Infancy to Adulthood: Meta-Analysis and Dynamic Modeling of Developmental Mechanisms

A central tenet of attachment theory is that a person's attachment pattern in adulthood is a reflection of his or her attachment history - beginning with the person's earliest attachment relationships. However, the precise way in which early representations might shape adult attachment patterns is ambiguous, and different perspectives on this issue have evolved in the literature. According to the prototype perspective, representations of early experiences are retained over time and continue to play an influential role in attachment behavior throughout the life course. In contrast, the revisionist perspective holds that early representations are subject to modification on the basis of new experiences and therefore may or may not reflect patterns of attachment later in life. In this article, I explore and test mathematical models of each of these theoretical processes on the basis of longitudinal data obtained from meta-analysis. Results indicate that attachment security is moderately stable across the first 19 years of life and that patterns of stability are best accounted for by prototype dynamics.
