Our aim was to compare self-report data with actigraphic data. Thirty non-demented individuals with PD and 14 normal control participants (NC)(More)

This effect has typically been studied using single list-learning trials, but in neuropsychology, multi-trial list-learning tests(More)
Two of the most commonly used methods to assess memory functioning in studies of cognitive aging and dementia are story memory and list learning tests. We hypothesized that the most commonly used story memory test, Wechsler's Logical Memory, would generate more pronounced practice effects than a well validated but less common list learning test, the(More)
