Systematic monitoring by the therapist of the quality of the client's mentalization across the session. The therapist tracks signs of loss of mentalization, recognizes the move into non-mentalizing modes, and chooses the appropriate response. This is a diagnostic skill — the ability to tell in real time whether the client is mentalizing or has lost the capacity. Detecting a failure triggers the chain: stop → validate → rewind → inquire.
Step-by-step guide
- Monitor markers of loss of mentalization: rigidity of thinking, certainty about the motives of others, black-and-white judgments, repeated accusations, emotional escalation
- Identify the specific non-mentalizing mode (psychic equivalence, pretend mode, teleological stance)
- Gently name the noticed pattern: "I notice that right now it has become hard for us to think about feelings"
- Choose the appropriate intervention: at high arousal — validation and stop; at low — inquiry and challenge
- Help the client over time to notice moments of loss of mentalization themselves
When to use
- Continuously, throughout the session — this is a background monitoring
- Especially attentive when discussing significant attachment relationships
- When the client becomes unusually certain in their judgments about others
Key phrases
It seems to me right now it has become hard for us to think about feelings. This is normal.

Warnings
- ⚠️ Do not shame the client for the loss of mentalization — it is a normal reaction to stress
- ⚠️ Name the process, do not evaluate: "It has become hard for us to think" instead of "you stopped thinking"
- ⚠️ Use "we", not "you" — emphasizing the joint nature of the process
