Gestalt and Experiential Techniques on the NCMHCE: Empty Chair, Two-Chair, Contact Boundaries, and When Not to Use Them

By David Zimmerman · 8 min read · Clinical content

Gestalt therapy, humanistic therapies, emotionally focused therapy, and somatic therapy all appear on NBCC’s list of the frameworks counselors use most[5], and the experiential techniques they share (empty chair, two-chair, staying with the feeling, exaggeration, attention to the body) show up in Domain 4 items. This post covers the Gestalt vocabulary[1][4], the emotion-focused version of chair work[2][3], and when these techniques are and are not the keyed answer. Seven scenarios follow.

Gestalt concepts by name

ConceptMeaning
Here and nowThe present moment, including body and nonverbal experience, is where change happens; "what" and "how" over "why"
AwarenessThe goal and the method: full contact with what one is experiencing
Contact and contact boundaryMeeting the environment while remaining oneself; disturbances at the boundary maintain problems
IntrojectionSwallowing others' rules and beliefs whole ("shoulds")
ProjectionAttributing one's own disowned feelings to others
RetroflectionDoing to oneself what one wants to do to others (turning anger inward)
ConfluenceLoss of the self–other boundary; merging
DeflectionAvoiding contact through humor, abstraction, changing the subject
Unfinished businessUnexpressed feelings from the past that intrude on the present
Figure and groundWhat stands out in awareness against the background; healthy functioning forms and completes figures
Paradoxical theory of changeChange comes from becoming fully what one is, not from trying to be different (Beisser)
Top dog / underdogThe internal critic and the defensive, apologetic part; a classic two-chair split

The techniques

  • Empty chair: the client addresses an absent person (or a part of self) directly to complete unfinished business.
  • Two-chair: two sides of an internal conflict (top dog and underdog, critic and experiencer) speak to each other from separate chairs.
  • Exaggeration: amplify a gesture or phrase until its meaning becomes clear.
  • Staying with the feeling: resisting the urge to escape a difficult emotion so it can be experienced and integrated.
  • Language experiments: “I” for “you/it”; “won’t” for “can’t”; turning questions into statements.
  • Making the rounds: in a group, saying something to each member in turn.
  • Dream work: the client becomes each element of the dream in the present tense.
  • Body awareness: “What is your jaw doing right now?” Somatic approaches extend this to tracking sensation, grounding, and titration.

Emotion-focused therapy (Greenberg)

The individual EFT of Greenberg (distinct from Johnson’s couples EFT) is the research-based descendant of Gestalt chair work: the therapist watches for markers (a self-critical split, unfinished business with a significant other, a problematic reaction, unclear felt sense) and matches each to a task (two-chair, empty-chair, systematic evocative unfolding, focusing)[2][3]. Primary adaptive emotions are accessed and transformed; secondary reactive emotions (the anger that covers hurt) are worked through to what is underneath.

When experiential work is the keyed answer, and when it is not

Keyed: unfinished business, grief the client cannot feel, self-criticism, a client who intellectualizes, a body signal the client is not aware of, a group ready for here-and-now work. Not keyed: acute crisis, active psychosis, severe dissociation, or a client who has not consented to intensification; and never as the first move when safety is unassessed. Experiential techniques amplify; stabilization comes first.

Frequently asked questions

What is the empty chair technique for?

Completing unfinished business: the client addresses an absent person, or a part of self, directly in the present so the emotion is experienced and resolved rather than described. Two-chair work is the version for internal conflicts such as the critic and the experiencing self.

What are the Gestalt contact boundary disturbances?

Introjection (swallowing others' beliefs whole), projection (attributing one's own feelings to others), retroflection (turning against the self what one wants to do to others), confluence (loss of the self–other boundary), and deflection (avoiding contact).

When are experiential techniques contraindicated?

Without modification, in acute crisis, active psychosis, or severe dissociation, and before safety has been assessed. Experiential techniques intensify emotion; stabilization and the capacity to stay grounded come first.
