Unmentalized experiences comprise internal and external somatosensory information that is not transformed into a mental representation and hence, cannot serve as substance for thoughts or feelings. Instead, unmentalized experiences, especially painful ones, are revealed implicitly through physical states, impulsive actions, or somatic symptoms. Therapeutic work with patients who lack mentalizing abilities presents therapists with the need to adjust their therapeutic thinking and interventions to help their patients develop the capacity to mentalize. This paper discusses some clinical implementations on the theoretical thinking of unmentalized experiences, by focusing on therapeutic work with children and the therapist's role. The author suggests that children are relatively closer to the unmentalized areas in their mind, due to their developmental stage, and because of their ability to engage in more primary means of expression and behaviour, making access to the unmentalized areas relatively easy. Hence, clinical work with children offers fruitful possibilities in modifying a patient's raw, vague, toxic unmentalized experiences into more structured and formed mental experiences. The therapist needs to immerse him or herself in primary mental functioning parallel to that of the child, in order to connect and transform the child's unmentalized experiences. Clinical illustrations from a case of child psychotherapy are presented.
