Optic Ataxia Video

Optic ataxia concerns impairments in using visual information to guide motor movements. In the clip we see a patient who can recognize visual objects but with at least one of her hands she has a difficult time reaching out to grasp the objecta problem tied to impaired representation in the "how" visual pathway.

@Demitsi

The uploader of this video is my psych prof at ubc, he however is not the person conducting the experiment and had nothing to do with the techniques used.

@Demitsi well keep in mind, this video is obviously quite old, when psychiatric patients weren't exactly treated as they should have been. I don't think the neuropsychologist here was terribly rude, but he does seem to treat her as if being a somewhat slow child. It breaks my heart to see her suffering so much, though... but clinically, it's fascinating to see how specialised the dorsal stream is for guiding visually-directed actions.

Well in that kind of examinations, the doctor (or the neuropsychologist) has to follow a precise pattern of actions in order to *neutrally* assess the performance of the patient. That's the best way to have a reliable estimation of his impairments. The kindness and polite stuffs and all, that comes before and after the testing. During it, it might bias the results.

By the way I doesn't seem to me that the doctor is being particularly rude here.
