To better understand attachment from a cross-cultural and historical perspective, I have amassed over 200 cases from the ethnographic and archaeological records that reveal cultural models (D'Andrade and Strauss 1992) of infancy. The 200 cases represent all areas of the world, historical epochs from the Mesolithic to the present and all types of subsistence patterns (Appendix 1). The approach is inductive where cases with similar models of infancy are clustered into archetypes. My principal finding from this analysis is that, in the broadest overview, infants are, effectively, placed on probation and not immediately integrated into the society. Attachment failure is not seen as a potential problem but, rather, premature attachment to an infant whose existence may be fleeting is to be guarded against. Most societies view infants and even children as not-yet-persons. Infants are born into a state of liminality or incompleteness. Among the Wari, a baby is compared to unripe fruit as it is "still being made" (Conklin and Morgan 1996: 672) and the Nankani reserve judgment on the infant's humanity until they can be certain it is not a spirit or bush child (Denham et al 2010: 608). My presentation of results will first identify the main factors that give rise to delaying personhood and, second, to the cultural models which justify and guide the transformation of babies into persons. Variability in the way this non-personhood is characterized and in the steps that must occur to complete the process of constructing a person is great but not infinite. Hence, in the second half of the chapter, I will identify and discuss several archetypal cultural models of infancy. Attachment and Attachment Parenting In the middle of the last century, John Bowlby (1953), an English psychotherapist, advanced a set of ideas about the emotional ties between a mother and her infant and the deleterious effects of maternal deprivation. These propositions are now widely known as "attachment theory." A critical component of the theory was its universality; all mother-child dyads must engage in behaviors, which build and strengthen mutual bonds during a critical period from six-eighteen months. The theory has, since then, gathered adherents across a broad spectrum from developmental psychologists testing for evidence of "secure" versus "avoidant" or "ambivalent/resistant" attachment (Ainsworth, et al 1978) to social workers who point to attachment failure as the root of criminal behavior. Numerous empirical studies have extended attachment to non-industrialized societies with mixed results but, overall, they suggest considerable cross-cultural variability (Keller, 2007; van IJzendoorn and Sagi-Schwartz 2008; Tomlinson et al, 2010).
