Turbo-charge AEDP’s consolidation of brain growth and neural integration for your clients and yourself


Kate Halliday, LCSW is a psychotherapist based in Ithaca New York. She has been in private practice since 1998 after a number of years spent in community human service agencies.

Over the course of a long career, Kate has been influenced and enlivened by a wide variety of experiences and teachers. She began her career as a nursery school and elementary school teacher, and went on to train as a clinical social worker. A writer and a pragmatist, she was initially drawn to Solution Oriented and Narrative therapy. A longing to feel more effective in treating trauma led her to train in EMDR in 2000, and in 2009 she began learning AEDP. Like many of us in the AEDP community, Kate fell in love with the model from the first moment she saw Diana Fosha present a videotape; and in the years since, Kate has enjoyed every moment of AEDP-related experience.

After several years of assisting in Essential Skills courses, Kate recognized that her longing for more ongoing lived experience of AEDP might be realized by generating an AEDP community where she lives in the Finger Lakes region of New York State. Kate began offering AEDP training groups to local clinicians there in April, 2015, and is delighted that the project has taken wings. There are now ongoing groups studying and being supervised in AEDP with her. Many of these clinicians attend Institute trainings elsewhere, and some are now Experiential Assistants in Essential Skills classes. Kate’s original commitment was to make AEDP accessible and affordable to clinicians in her local region which is far removed from a large urban center; this remains a primary interest for her as she considers how AEDP may be promoted around the world.

Kate’s clinical work, evolving from early training in Developmental Psychology and subsequent professional experiences, has focused on Trauma, Dissociation, and their repair. She has always had a commitment to serving her own GLBT community, and for the past decade or more she has had something of a speciality in work with transgender people. She is also re-discovering a passion for time limited treatment as she participates in the AEDP Research project.

Kate currently supervises both in her office and over Zoom. She's been pleased to discover that the process of remote meeting turns out to offer most if not all of the emotional intimacy and efficacy of in person sessions. Especially for those of us in far-flung locations, online supervision and even therapy offer opportunities for personal and professional growth (and delight!).



There is generosity in receiving and absorbing loving-kindness. As Brene Brown puts it: “until we can receive with an open heart, we’re never really giving with an open heart”. The seemingly simple practice of being available for what Diana Fosha has termed the “bi-directional relational experience” that is fundamental to practice of AEDP can be challenging for many people. You might have already discovered in your AEDP journey how the scope and depth of rewards we receive from taking this relational challenge are in fact one of the gateways to State Four expansiveness and delight. To quote senior faculty member Yuko Hanakawa, we “facilitate an upward spiral of transformations beyond ….already accomplished therapeutic gains” of changes in attachment style and repair of Trauma. We have the lofty goal of supporting our clients beyond surviving their wounds into flourishing as a secure, joyful, and competent self.

Many of us, as we have learned AEDP, have remarked upon the dramatic differences it has caused in our professional efficacy. It’s also cause for celebration that we note a corollary and dramatic transformation in our personal relationships, both with ourselves and with others. As we ourselves participate in the deep healing work the model offers our clients, we receive equal benefit. (One colleague has remarked to me “I get a session for every session I give, when I really show up and use everything I’ve learned with AEDP!”)

This course aims to be an opportunity to “bring home” your theoretical knowledge of AEDP, to deepen your understanding of how the model works from the bottom up and inside out, starting with yourself. Alongside the reliable AEDP training components of didactic and video presentations we will use a variety of experiential exercises, with ourselves and with one another. As you’ve come to realize, the joy of learning AEDP is in the ways it potentiates access to delight. The hope is that this class will lighten your spirits and enhance your enjoyment of your practice as a

Course Objectives

  • Define AEDP’s theoretical perspective on the therapeutic importance of Receptive Affective capacity for clients and clinicians.
  • Apply concepts of AEDP’s four state model to recognize affective phenomena as they arise, and use this understanding to guide promotion of R.A.C.
  • Utilize skills articulated by AEDP to enhance “secure enough” attachment experiences by using “small m” metaprocessing to assess and deepen how both members of the therapeutic dyad are receiving one another’s presence.
  • Recognize opportunities for developing Receptive Affective Capacity specifically as they arise as State Three Transformational Healing Affects, which include “feeling moved, touched, or emotional within oneself and/ or feelings of tenderness, love, or gratitude toward the other, in this case, the therapist.” Diana Fosha (2009, 2011, 2020)
  • Explain how expanded focus on moments of gratitude and relational delight promote brain growth and neural integration.
  • Explain how ruptures and repair of ruptures enhance and deepen relational intimacy.
  • Recognize and reflect upon opportunities within ourselves as clinicians to grow our relational capacities, personally and professionally.
  • Role-play personal challenges: receiving expressions of positive emotions and ways to grow our own capacity.
  • Demonstrate the enhanced emotional, cognitive, and spiritual benefits of deepened relational experience
  • Develop curiosity around the mysteries of the energetic space between members of any dyad, and the beauty of AEDP’s theoretic model to explain, expand, and explore new frontiers in our awareness of those mysteries.
