Synthesizing Attachment Theory with the REBUS Model

A theoretical synthesis of attachment theory and the REBUS neuroscientific model offers an organizing framework for psychedelic science. Attachment theory holds that people develop internal working models (IWMs) of relational experiences that function as predictive models shaping social and emotional worlds. Effective psychedelic interventions may induce a hyper-plastic neural state that, supported by corrective relational experiences, facilitates rapid learning and revision of IWMs toward greater security. Three proposals guide future research: individual differences in attachment security predict psychedelic phenomenology and integration; increasing attachment security may be a clinical outcome; and clinical utility involves attachment-related dynamics such as connectedness and alleviation of worries.

Abstract

Abstract In this chapter, the authors synthesize the relational developmental perspective of attachment theory with a neuroscientific model: the RElaxed Beliefs Under pSychedelics (REBUS). This synthesis, the authors argue, can serve as an organizing framework for psychedelic science. Attachment theory posits that people develop internal working models (IWMs) of relational experiences with close others. These IWMs function as predictive models (“priors”) that, for better and for worse, contribute to people’s social and emotional worlds and organize how they navigate them. Effective psychedelic interventions may work by inducing a hyper-plastic neural state that, supported by corrective relational experiences (with therapists, God, or others), facilitates rapid and deep learning. This can include revision of IWMs toward greater security and other psychological transformations. Based on the attachment-REBUS synthesis, the authors describe three main proposals to guide future research. First, individual differences in attachment security predict the phenomenology of psychedelic experiences and processes related to their integration. Second, increasing attachment security may be a clinical outcome of efficacious psychedelic therapy. Third, among other process-level mechanisms, the clinical utility of psychedelic treatment involves attachment-related dynamics (e.g., connectedness to others and God, alleviation of attachment-related worries and defenses). Finally, the authors provide words of caution and future directions.
