| Research Abstract |
Frustration is shown to evoke aggressive behaviors that variesacross individuals. Using an fMRI, the present study investigated cognitive and neural basis of such individual differences in aggressive behaviors. As the results, individuals who preferred to direct their aggression toward others showed greater activation of the ventrolateral prefrontal cortex which includes the orbitofrontal cortex. The activation may reflect emotional processing under frustrating situation. On the other hand, in those who preferred to direct their aggression toward themselves, greater activation was observed in the left dorsolateral prefrontal cortex, raising a possibility that they make effort to reduce aggression.
