Memory Perception And Strategy Use In Parkinson's Disease, Andrew Johnson, Carrie Pollard, Philip Vernon, Jennifer Tomes, Mandar Jog
Andrew M. Johnson
Although there is growing support for the existence of memory deficits within Parkinson's disease (PD), little has been done to evaluate the extent to which PD patients demonstrate differences in their use of metacognitive strategies. In the present study, 79 PD patients (46 men and 33 women) and 49 age-matched healthy participants (19 men and 30 women) were compared on a metamemory questionnaire. PD patients reported significantly less strategy-use than age-matched controls, particularly with regards to external memory strategies (such as making lists). This suggests that auxiliary treatments such as memory strategy training might be effective in this population.

A Role Of The Basal Ganglia In Movement: The Effect Of Precues On Discrete Bi-Directional Movements In Parkinson's Disease, Andrew Johnson, Philip Vernon, Quincy Almeida, Linda Grantier, Mandar Jog

The effect of a precue on improving movement initiation (i.e., reaction time; RT) is well understood, whereas its influence on movement execution (i.e., movement time; MT) has rarely been examined. The current study investigated the influence of a directional precue (i.e., left vs. right) on the RT and MT of simple and discrete bi-directional movements in a large sample of Parkinson's disease patients and healthy control participants. Both patients and controls were tested twice, with testing sessions separated by 2 hours. Patients were tested first following an overnight levodopa withdrawal and again after they had taken their medication. Both patients …
