Patients with Huntington's Disease (HD) and matched normal controls attempted to recall items of general information, made “feeling-of-knowing” judgments about unrecalled items, and attempted to recognize correct answers. The HD patients had impaired recall, but they were as able as normals in recognizing what they couldn’t recall. In addition, they were as accurate as normals in predicting whether they could recognize unrecalled information. Unlike normals, however, the HD patients did not spend more time searching for material they believed they were likely to recall than material they believed they were unlikely to recall. The results suggest that the dementia of HD includes a defect in the metamemorial control processes that direct retrieval efforts.
