“…Classical theories of grief include: the “Five Stages” model, describing a sequence of emotional states (Kübler-Ross & Byock, 1969); attachment theory-based descriptions of painful bond breaking (Bowlby, 1979); and the “Dual Process” model, describing oscillation between loss processing and restoration (Schut, 1999). More recently, models informed by neurobiology and/or behavioural neuroscience have suggested that learning (O’connor & Seeley, 2022; Boddez, 2018), representational change (Shear & Shair, 2005), competitive (Békés, Roberts, & Németh, 2023) and cognitive-behavioral (Maccallum & Bryant, 2013) processes play central roles in grief, and may have identifiable neural correlates (Gündel, O’Connor, Littrell, Fort, & Lane, 2003).…”
