oh - the highly repetitive response common in autism.

Are there gradients of perseveration? This is absolutely fascinating - a brain based answer to why people do many behaviours - from sitting in the corner mumbling one word over and over, to various forms of self sabotage ("always picking the wrong man")

(And I might say heartening - as the father of an ASD child, it can seem hopeless, but just being armed with some knowledge of where the behaviours come from might allow some hope)
