Abstract
Patients with Huntington's Disease (HD) were tested on 2
tasks, probabilistic classification learning and artificial grammar
learning. Both tasks are performed normally by amnesic patients and
are considered to be independent of declarative memory. Patients
with HD were severely impaired in probabilistic learning but
performed normally in artificial grammar learning. The probabilistic
classification task may be akin to habit-learning tasks that depend
on the neostriatum, whereas artificial grammar learning may depend
on changes within neocortex similar to what is thought to occur in
perceptual priming. The deficit in the probabilistic classification
task indicates that impaired nondeclarative learning in patients
with HD occurs not only in motor tasks but also in nondeclarative
learning tasks that have no motor component.
