Effects of sudden insight on long-term sentence priming in Alzheimer's disease.
The purpose of this study was to demonstrate spared, long-term sentence priming in individuals with Alzheimer's Disease (AD) using a sentence puzzle task. The sentence puzzle task required a decision--either yes or no--regarding the correctness of an answer supplied for a sentence puzzle. Twelve persons with AD, 12 older controls, and 12 younger controls took part. Speed of response (deciding if a puzzle answer was correct or incorrect) was recorded, with increased speed at retesting after 30-min and 1-week delays used as an index of priming. Individuals with AD demonstrated sentence priming over both a 30-min and 1-week delay, comparable in form to that of controls. In addition, persons with AD were affected by stimulus parameters (correct/incorrect puzzle answers; difficult/easy puzzles) in a similar manner as were controls.
