I'm writing this as part of an {{ Educational assignment}} at university. It's unfinished as of yet but I aim to complete it by end of January. I still need to add the sub-topics 'relationships' and 'integration' as well as topics Implications on Development/Attachment' and 'Applications for Patients/Clinicians.' There are plenty more journal articles I am gathering to ensure this is verifiable information.

This was a Requested Journal article under the Psychology/Social Science wikiproject and due to the wide array of journal articles/studies involving Interpersonal Neurobiology (IPNB), as well as books and reputable psychologists who conjured it, I dont think it's a fringe theory.
