| Abstract |
OBJECTIVES
To develop reliable tools for measuring communication skills in schizophrenia, the present study proposed the concept of communication intelligence, consisting of conversational competence, emotional competence, and empathic competence, and explored its neurobiological underpinnings using regional gray matter volume with healthy people.
METHODS
Communicative intelligence scores were obtained from 126 healthy young participants. Correlation analyses between regional volume distributions and communication intelligence subcomponents were conducted using voxel-based morphometry of structural MRI.
RESULTS
The significant positive correlations between the regional gray matter volumes with conversational competence were found mainly at the ventromedial frontal gyrus while the negative correlations between the bilateral middle frontal gyrus. With emotional competence, the volume of right superior temporal gyrus was positively and that of bilateral insula was negatively correlated. With empathic competence, the volume of the left middle frontal gyrus was positively and that of the insula was negatively correlated.
CONCLUSION
Each of the subcomponents of communicative intelligence scores showed distinctive neurobiological underpinnings. The regions for the subcomponents, which constitute a common network for social cognition and emotion, are highly associated with the regions of the schizophrenia pathology. In conclusion, communicative intelligence scales have neurobiological basis to evaluate social skills of patients with schizophrenia. |
