| Research Abstract |
The present study aimed to reveal how emotional and social information affects the central executive of working memory. In order to achieve the goal, we employed onomatopoeia that describes one's affective state, and a self-reference paradigm that directs participants' attention toward their own or other's personality trait. Brain activation was measured while participants were performing the task with a functional magnetic resonance imaging (fMRI), which allowed us to specify brain regions integrating emotional brain, social brain, and intelligent brain (central executive). We also performed a transcranial magnetic stimulation study and the structural equation modeling analysis to investigate the neural network underlying the central executive of working memory.
