>From Gazzaniga's Cognitive Neuroscience There can be an apraxia related to language production. This is seen in difficulty pronouncing words. More commonly apraxia is related to motor control. There are two classifications of apraxia, ideomotor and ideational. A patient with ideomotor apraxia "appears to have a rough sense of what the desired action is, but has problems executing the action." A patient with ideational apraxia has their "knowledge about the intent of the action disrupted." In this case the patient will no longer understand the intent of a tool.

I am using Josephine Wilson's text and I think I have found some conflciting information, which a student pointed out to me. The text states, "This disorder is not due to a motor dysfunction, however, or to an impairment in language comprehension..." Later on in the paragraph it states, "..., but they cannot perform the appropriate movements in response to a verbal command." Now, doesn't this seem conflicting to you? The text says that it is not due an impairment in language comprehension, but then later says a movement cannot be perfoemed in response to a verbal command? Isn't language comprehension and a vrebal command the same thing? I thought, as I was taught, that the problem laid in the fact that a person with this disorder couldn't understand what is being asked of them. For example, if I put a toothbrush in front of you and you are the one with apraxia, and I ask you to brush your teeth, you cannot perform this function because you do not understand what I am asking of you. Any help???? Nina Nina L.
