Psychologist Dr LeGoff (USA) in 2004 developed the theory around LEGO® after he noticed that children with Autism Spectrum Condition (ASC) were playing with LEGO® and interacting with each other in his waiting room. Of all the toys available in the waiting room children preferred to play with LEGO® and he therefore chose this as a medium to promote and develop collaborative play. He, and other researchers, have since found that the level of social interaction in children with ASC increased when they are engaged in games and LEGO® based therapy was therefore rewarding to children with ASC.
