It's in the trauma books. There is discussion about "gently" withholding what a client needs to allow things to be worked through. And what a client needs is usually the stuff they were deprived of in childhood. That's what draws transference feelings out the most.

Gently being the key word here. For example, if a client always seeks validation, then withholding it will get at that need, process deep emotions, and let a client understand why she needs it and how it affects her etc. It's a common technique, I believe. However, this doesn't mean you withhold all validation for weeks, months at a time. It doesn't even mean you do it an entire session.
