This week's programme in the series on Man and Science today.

Irene Kassorla is an American therapist who has worked in this country with mentally ill children who have apparently no communication with the outside world, children whose parents had almost given up hope of making contact with them. Gradually, under her care, they begin to react; to produce words that are relevant, to frame sentences.
This film, made during actual therapy sessions over a period of six months, shows the remarkable effects of her simple method: how she has given new hope to troubled parents and restored, at least partly, the bridge of communication to three children.
