The term ‘corrective emotional experience’ is most often used to refer to the repair of a misattunement in the therapist-client relationship.
Misattunements include misunderstandings, misinterpretations, or even mistakes on the part of the therapist.
In response, the repair can take the form of an apology, for example, if one of your comments was misunderstood by your therapist. Or maybe you needed to hear a comment or reflection that deepened the therapeutic relationship.
Traditionally it refers to a unique and healing interaction with your therapist.
