According to Spolin, Boyd's teachings provided "an extraordinary training in the use of games, story-telling, folk dance and dramatics as tools for stimulating creative expression in both children and adults, through self discovery and personal experiencing." Building upon the experience of Boyd's work, she responded by developing new games that focused on individual creativity, adapting and focusing the concept of play to unlock the individual's capacity for creative self-expression. These techniques were later to be formalized under the rubric "Theater Games".
