I've been led to read some of the stuff on the neurobiology of attachment too... Fairly interesting. There is some stuff on the attachment styles of infants (secure, disorganised etc) and the neurobiology of those attachment styles. Kind of psychodynamic theory gone scientific.

It is especially relevant to developmental explanations of personality disorders. Borderline Personalilty Disorder, for example, had been characterised as a disorder of emotion regulation, and also as a disorder of attachment. I read something the other day on theory of mind and mentalization and about how when the attachment system is activated theory of mind / ability to mentalize seems to go out the window for these people.

One notion is that teaching the ability to mentalize while the attachment system is activated is the 'active' ingredient in mentalization, interpersonal, schema, dialectical behaviour, transference, and cognitive based treatments.
