Breaking the back of love: attachment goes neuro-molecular
This chapter explores how attachment theory is increasingly going ‘under the skin’, looking for fundamental biological mechanisms to explain behaviours and consequences. Attachment scholars and researchers have sought new alignments with developments in evolutionary biology and developmental neuroscience. All these domains — despite inconsistent findings, thorny issues relating to extrapolations from animal work, and problems with replication — are purported to provide further support for attachment theory's veracity. In addition, they dangle the tantalising prospects of better targeting of interventions and more efficacious clinical approaches to fixing the effects of disrupted attachments, including some normative and sensitive matters such as the onset of puberty, and what are somewhat euphemistically called ‘reproductive strategies’, often meaning girls having babies too early. This ‘new generation’ of biological reasoning looks to the molecular level to explain health inequalities, with the prevention of adverse childhood experiences on the ‘to do’ list for public health policy makers. This has profound potential implications for child welfare practices.
