Attachment theory is well-recognised for understanding and treating adult love relationships. Neuroscientific research highlights the implicit process of attachment and the unconscious, nonverbal, bodily-based, and affect-regulating interactions of the right brain hemispheres in attachment development. Effective couple therapy ought to consider the implicit processes between infants and caregivers as a model to develop secure attachment in romantic partners, which makes dance/movement therapy (D/MT) a valuable treatment modality. Mirroring is a staple D/MT intervention that involves imitation of a client’s movement by the therapist to enhance attunement and empathy. In this paper, the author explores the overlap between attachment theory, neuroscience, dance/movement therapy, and couple therapy. A theoretical model is proposed for the use of mirroring with couples to foster secure attachment by means of attunement on a bodily-based level. Future research is suggested in order to measure the effectiveness of mirroring on couples’ attachment.
