Why the playroom?

Playroom techniques have been criticized because they are at once a diagnostic and a therapeutic tool. But in my experience this is actually a great advantage. Play technique is frequently successful in both areas. And it is theoretically a sound principle to do psychological exploring studies on a child in the process of treatment, education and re-education. Pedagogy, psychotherapy of children and child psychology should become recognized more and more as closely related and inseparable disciplines.
