Cornerstones and discourses in attachment study: celebrating the publication of a new landmark.

is a landmark history of five major research groups that have helped establish the empirical foundations of the Bowlby-Ainsworth attachment tradition. This essay highlights Duschinsky's use of historical methodology rather than the narrative-style review more familiar to psychologists. We then turn to a recurring theme in the book, the inconsistent use of language and theoretical misunderstandings, especially as they arise at the interface between attachment study and more applied disciplines. We discuss Duschinsky's sociological analysis of how these difficulties arose and are maintained and our own perspective, which emphasizes more difficulties attending communication across declining and emerging paradigms. We expect will be a significant asset as we try to establish new modes of collaboration and communication with educators, clinicians and other practitioners who work not with abstractions and populations but with individuals presenting complex histories and living complex lives.
