“…To this end, recent personality disorder research has focused on developmental issues with relevance for multiple personality disorder constructs, including reward processing (White et al, 2014), stress responses , emotion regulation (Gratz et al, 2014) and social cognition (Sharp & Vanwoerden, 2014). Over recent years there has been increasing interest in the emergence of borderline personality disorder (Arens et al, 2013;Bornovalova, Hicks, Iacono, & McGue, 2013;Chanen & McCutcheon, 2013;Stepp, Olino, Klein, Seeley, & Lewinsohn, 2013) and evidence to suggest that the disorder may have roots in early development is accumulating (Goodman, Patel, Oakes, Matho, & Triebwasser, 2013;Lopez-Castroman et al, 2013;Perroud et al, 2013;Siever, 2008). In this paper, building on earlier work on the significance of attachment and mentalization for the development of BPD (see Allen, Fonagy, & Bateman, 2008;Fonagy & Luyten, 2009;Fonagy & Luyten, in press;Fonagy, Luyten, & Strathearn, 2011), we propose a developmental framework that conceptualizes BPD in terms of a specific underlying vulnerability to psychopathology (Fonagy, Luyten, & Allison, 2014).…”
