Denny-Brown takes a more holistic approach and suggested ideational apraxia results from diffuse brain damage. Body part as object is a relatively new concept in scientific literature. Past studies have suggested that BPO pantomimes may allow aphasics to avoid an impaired cognitive function. By not having to reproduce a movement outside of the usual context, they can have a more vivid experience of acting on an object. What is known as BPO pantomiming in children was first discussed in Goodglass and Kaplan’s
