This volume presents a new theory on attachment that broadens its range to ages beyond infancy, to many cultures and to endangered populations. The intent is to provide new theory and methods to better understand human variation in interpersonal and cultural self-protective strategies. Quality of attachment has been a key variable in developmental research during the last two decades. Even though attachment is relevant to all cultures and humans of all ages, the majority of research has focused on middle class infants in Anglicized cultures. The expansion of the attachment classificatory system beyond its roots in infancy and to a broad range of cultures differentiates this volume from other work on attachment.
