Attachment-past and present. But what about the future?

This essay acknowledges the seminal contribution of the founders of attachment theory and research as a paradigm shift in understanding the importance of the socioemotional foundation of developmental processes. However, it is surprising that attachment theory has been treated as a closed system by its students with remarkable resistance to change and further development of theory and methodology. Especially three dimensions are identified that would help to advance attachment theory as a valid conception also for the future. The context specificity of evolutionary theorizing, the different socialization goals and parenting strategies across cultures and the new insights in infant development need to be taken into consideration in order to develop a valid theory of socioemotional development as the culturally informed solution of universal developmental tasks.
