In the latter part of her career, Clark focused more on art therapy and less on the actual creation of a work. When she returned to Rio de Janeiro in 1976, Clark's therapeutic focus rest upon the memory of trauma. When she changed her creative direction in 1971, she wrote "I discovered that the body is the house...and that the more we become aware of it the more we rediscover the body as an unfolding totality." She wanted to uncover why the power of certain objects brought about a vivid memory in her psychotherapy patients so that she could treat their psychosis. Depending upon the individual, the sessions could be short-term or long-term, in which treatment came about through the relationship between the relationship object and how the participant interpreted its meaning.
