Abstract

Objective: This study investigated whether emotions and enactment can jointly increase memory performance in nondemented Parkinson's disease (PD) and Alzheimer's disease (AD) patients.

Method: Actions' drawings with negative, positive, or neutral valence were presented to 17 PD patients, 17 AD patients, and 37 elderly controls, matched to age. Two conditions of intentional encoding were proposed to each participant: one verbal, in which participants had to name the represented actions; and one motor, in which they had to mime the displayed actions. Thereafter, participants were submitted to an immediate free recall task and a delayed recognition task.

Results: The enactment effect was found in all three groups. The effect of emotion was also observed in that all three groups recalled negative actions better than both neutral and positive (PD patients), only neutral (AD patients), or only positive actions (elderly controls). Positive actions were not recalled better than neutral actions in any group.

Conclusions: These results constitute an evidence for the preservation of the enactment effect and of the emotion effect on memory in AD and PD patients. However, they do not support the hypothesis of the combined effect of emotion and enactment on memory, neither in AD and PD patients nor in normal aging.
