Under the leadership of its founding editor, Dante Cicchetti, Development and Psychopathology has been recognized for decades as the foremost journal integrating developmental theory and clinical research programs. Contributors have often highlighted the implications of attachment theory and research for understanding developmental processes and pathways, and as a testing ground for intervention strategies. In this paper we reflect on the strengths and limitations of the traditional developmental perspective. We suggest that behavioral, cognitive, and emotional development are better understood as a process of bricolage (construction within constraints). This perspective is illustrated in an analysis of change mechanisms, and behavioral and representational changes, in attachment development from pre-locomotor infancy to later adulthood. Special emphasis is placed on ordinary learning and cognitive processes, rather than those specific to attachment, and on the roles that socialization pressures and changing circumstances play in shaping the course of attachment development.
