Outline of Final Research Achievements |
Older adults experience memory decline thereby hampering fluent communication. To facilitate their memory performance, positive emotions have been shown to have a beneficial effect (the age-related positivity effect). However, the neural basis underlying this effect within the language domain remain unclear. Using functional magnetic resonance imaging (fMRI) and voxel-based morphometry (VBM), this study assessed in what way age-related changes influence the role positive emotion plays during sentence processing. Results indicated that, in comparison with the younger counterparts, the older participants recruited broader regions including the putamen, the hippocampus, and the insula, for positive emotional sentences than neutral ones. VBM analysis found that the gray matter volume (GMV) in the dorsomedial prefrontal cortex (dmPFC) predicted the positivity effect during sentence retrieval. GMV in the dmPFC might underlien older adults’ retrieval of positive emotional sentence.
